Concrete polishing pad renovation process

Concrete polishing pads are specially formulated for use in industrial floors, warehouses, parking lots, concrete floors, cement self-leveling floors, various aggregate hardener floors and liquid hardener floors. Processing is as follows:

Old ground renovation

1. Base surface treatment: the ground water is fully immersed, and the loose surface layer is fully washed with a high-pressure washing machine or a refurbished machine with a hard brush, and the hollow drum portion is treated separately;

2. Damage repair: use water absorption machine to absorb surface water, apply interface agent, use the repair according to the requirements: material repair and maintenance according to the specifications;

3. Leveling: use TFP series concrete polishing pad or metal polishing pad (water mill or dry grinding);

4. Rough grinding: use 50#-200# series concrete floor renovation tablets;

5. Infiltration treatment: according to the standard use of concrete liquid hardener hardening treatment, if the original ground hardness is poor, it is recommended to do an infiltration hardening treatment before rough grinding;

6. Fine grinding: use 200#-300# series concrete floor renovation. If the hardness of the ground after the osmosis hardening meets the construction requirements, sanding will not occur during fine grinding;

7. Fine grinding and rough polishing: use 500#-1500# series concrete floor renovation film;

8. Washing and drying: thoroughly clean the floor with a refurbished machine with a cleaning pad, and dry it with a water suction machine;

9. Infiltration glazing: use concrete permeable brightener or similar products, pay attention to different processing techniques of different products;

10. Fine polishing: use concrete polishing sheet 3000# (select 1-2 particle sizes as needed).
For new ground infiltration treatment, the best polishing pad manufacturers recommend infiltration treatment after “fine grinding”. If sanding occurs on the ground during fine grinding, it is recommended to do an infiltration hardening process before fine grinding.

Precautions

1. According to the needs and experience, choose different types of refurbished machines and polishing pads. The grinding effect will be affected by various factors: ground hardness, grinder weight, counterweight, rotation speed, whether water and water quantity, polishing pad type, quantity, polishing Pad size, grinding time and experience, etc.;

2. According to the ground hardness and technician experience to choose different size number polishing pad, available for selection of granularity number including 30#, 50#, 100#, 150#, 200#, 300#, 400#, 500#, 600#, 800# , 1000#, 1500#, 2000#, 3000#, commonly used granularity number is: 30#, 50#, 150#, 300#, 500#, 1000#, 2000#, 3000#, according to the actual situation, you can use the jump level to select The effect is related to the hardness of the ground, the flatness, the size of the polishing pad, the grinding time and the experience of use. In the whole process, coarse grinding and fine grinding are more uniform and thorough, and fine grinding and polishing will save trouble and better effect. ;

3. Dry grinding, water mill using different formulations of polishing pad, water mill can reduce on-site ash and improve efficiency;

4. It is recommended to clean the ground before polishing the polishing pad for the next size. Otherwise, it will affect the grinding effect.

Quartz polishing pad processing precautions

The masters who have processed the stone will know that some stones are very well processed, and some stones are very difficult to process because the hardness is too high. Especially in the processing of quartz polishing pad, the hardness of quartz stone can reach Mohs 7, so its plasticity is not as easy as ordinary artificial stone and acrylic, and the processing technology is higher than other artificial stone. There are various problems in processing, how to avoid it?

Quartz stone joints should be spliced ​​with 45° anastomosis. When splicing, the connecting surface must be straightened with a straight knife, and the butt joints can be connected seamlessly. Before connecting, the glue color must be tested first, and the color can be spliced ​​before it can be connected. The remaining glue at the joint is removed by a small blade after the gel is not hard. When the glue is hardened, it is polished and the grinding range is not suitable.

Quartz stone will have a trace like a thread when it is connected, but it is not easy to see without careful observation, and it does not affect the appearance. Mainly open hole: When opening the furnace hole, the bottom of the quartz stone plate should have a backing plate, which can not be suspended, and the bearing force should be uniform to prevent cracking during the opening process due to uneven force. Before opening the hole, first strengthen the four sides and the middle of the quartz stone, and then punch the holes at the four corners of the furnace hole. Then use the wire cutter to cut the square shape slowly and evenly. When cutting, the plate cannot be cut through. It should be divided into two steps. Cut, cut the thickness of the sheet by 1/3, and cut the sheet through the two steps to prevent the sheet from cracking.

After the furnace hole is cut into squares, the angle of the arc of the angle grinder is ground into a circular arc angle. The radius of the arc is not less than R10mm. The back of the four corners of the furnace hole is thickened with a small plate of about 120×120mm, and then grinded into a corresponding angle grinder. The arc is thickened on the four sides by a quartz stone plate with a width of 30 mm or more. The distance between the edge of the furnace hole and the rear water barrier is not less than 70mm.

Look at the edging and chamfering: use hard diamond polishing pad, first 50#, after 150#, then 300#; when polishing with Tianbang diamond water grinding plate, start with 500# polishing pad, then use 800# in turn. Polishing pads of 1000#, 1500#, and 2000# are polished. Note that the diamond polishing pad must be hard and must be emphasized with the supplier. The size of the polishing pad is 3 or 4 inches, depending on the needs of the application. After the use of glue: the original glue of the quartz manufacturer should be used, and the glue must be thoroughly stirred before the glue is used.

The glue curing agent is similar to the ordinary artificial stone curing agent, and the relationship between the addition amount and the temperature is as follows:

(1) when the temperature is below 10 ° C, the amount of curing agent added is 1.5-2% of the glue;

(2) When the temperature is between 10 ° C and -20 ° C, the curing agent is added in an amount of 1% of the glue;

(3) When the temperature is between 20 ° C and -30 ° C, the curing agent is added in an amount of 0.5-0.8% of the glue;

(4) When the temperature is above 30 ° C, the curing agent is added in an amount of 0.5% of the glue.

The difference between polished and polished marble polishing pad

Because of the long-term use of marble, the crystal surface brightness and gloss disappeared on the marble surface, which affects the overall decoration design inside the home. Then, when the brightness and gloss of the marble polishing pad disappear, what method can be used to make the marble polishing pad re What about the glow? Generally in this case, we need to polish the marble to re-gloss the crystal face of the marble.

When marble is polished, different polishing and polishing processes are used depending on the type of marble, and the polishing process of the flat plate is different from the polishing process of the arc panel. Therefore, we should pay attention to the following when polishing and polishing.

1. After continuous polishing of the crystal layer and crystal layer after polishing the stone grinding block (commonly known as crystal face care), the pores are not completely closed, and the stone can be breathed inside and outside, and the stone is not easy to be diseased. At the same time, it has a certain waterproof and antifouling effect.

2. After the marble waxing and polishing, the stone pores are completely closed, the stone can not be breathable inside and outside, so the stone is prone to lesions.

The difference between marble polishing and wax polishing

Marble polishing and waxing and polishing can make the stone bright and beautiful, so what is the difference between the two? The best polishing pad manufacturers below mainly introduce the difference between the two in terms of essence, appearance and extension operation.

At present, stone surface treatment is one of the most ideal curing methods for marble. It does not change the structure of the stone, so it does not change the texture of the original stone. After the crystal surface treatment, the stone surface molecules are denser, and the gloss brightness is obviously improved, making the stone surface brighter and more noble. Stone waxing can make the stone color bright. Stone wax is a water-soluble material. When it is used, it will produce a protective film on the top of the product. This will improve the brightness of the stone, but its protective effect on the stone is Limited, poor weather resistance, anti-fouling effect is not ideal, and it is easy to attach dust.

Nowadays, people also find that waxing also causes some harm to the stone, because it is applied as an airtight cover protection material on the surface of the stone. After the pores of the stone are closed, the moisture inside and behind the surface is not released. In the interior of the stone, the stone has been damaged for a long time. Marble grinding is the last step in the process of stone care crystal surface processing or stone light board processing. It is one of the most important processes in today’s stone care, which is different from the marble cleaning and waxing polishing in the traditional sense of cleaning company business.

First, the essential difference

1. Marble grinding polishing is a prelude to stone surface treatment or a necessary process in stone processing. The main principle is to use the pressed grinding block synthesized by mineral acid, metal oxide and other materials to match the pressure of mechanical grinding disc, high-speed grinding force, frictional heat energy, and the physical and chemical cooperation of water on the smooth surface of marble. Thereby forming a new layer of bright crystals. This crystal layer has an ultra-bright, clear luminosity. The luminosity can reach 90-100 degrees. This crystal layer is a modified crystal layer of a stone surface layer (1-2 mm thick).

2. Marble cleaning is a prelude to marble waxing and polishing, marble cleaning waxing polishing is a relatively popular marble cleaning and maintenance protection measures in the early 80s-90s, and now has lost the market and the meaning of existence. Its essence is a thin coating of acrylic resin and emulsion polymer covered on the surface of the new stone (polished board), which is often referred to as water wax or floor wax. The high-speed, low-pressure polishing machine is combined with the fiber mat to rub the surface of the stone to make the resin coating more bright. Due to the product update, later appeared special light wax, wax-free, etc., this coating is similar to the oil varnish on the wooden floor.

3. The polishing process of the grinding block before the marble care crystal surface treatment is the physical and chemical cooperation process between the stone surface layer and the chemical. The surface layer of the stone is completely integrated with the bottom layer, and there is no separation layer.

4. The wax layer on the marble waxing is attached to the surface of the stone, a layer of resin film, and there is no chemical reaction with the stone itself. This wax layer can be shoveled with a blade to cut the wax film off the surface of the stone.

Second, the difference between representation

1. Polishing and polishing of marble grinding blocks is the prelude of crystal face care stone care. After polishing and polishing, the luminosity is high, the definition is high, the wear resistance, the resistance to stepping, and the scratching are not easy. It is the true embodiment and value extension of the stone use function.

2. The stone after polishing and polishing the luminosity is low, the luminosity is not clear, and it is very fuzzy, not wearable, not water resistant, easy to scratch, oxidized and yellow to reduce the essence of the stone.

Third, the difference between extension and operation

Generally speaking, the steps of the appeal can basically handle the marble surface, but sometimes we encounter artificial stone like jazz white and resin. After the completion, the surface may not be very bright, we can spray A2 again. The syrup is ground to 3000#, then repeated with nano-pad, with marble mirror complex cream NO2, 2X mirror lock bright knife into the milk Q5 for polishing, the effect of water bright will be much better than before.

How to choose polishing pad for floor construction

We all know that whether it is in construction or road construction, it will involve the construction of the floor. For the construction of the floor, polishing pads will be used. There are many kinds of polishing pads, such as water polishing pad, soft diaphragm and iron diaphragm. Wait, how do we choose to face such a wide range of polishing pads? This is indeed a difficult thing for newcomers to build. Don’t worry, Tianbang will reveal how to choose a polishing pad for the construction of the floor.

First, how to choose polishing pad for floor construction

Commonly used concrete polishing pads mainly include the following:

Polycrystalline diamond polishing pad: used to remove epoxy coating, it needs to be used when the coating is thicker; concrete diamond polishing pad: used for concrete floor leveling and old ground renovation; concrete thick polishing pad: usually refers to thickness more than 5mm Diamond resin polishing pad for concrete floor leveling, rough grinding, fine grinding, fine grinding and polishing; concrete thin polishing pad: usually refers to diamond resin soft polishing pad with thickness less than 5mm, used for coarse grinding and fine grinding of concrete floor. Fine grinding and polishing; concrete polishing: usually made of rayon, wool or other animal hair, and some products are also added with some abrasives and polishing accessories for the polishing of concrete floors;

How do we choose and use such a wide range of polishing pads? To understand how to properly select and use polishing pads, we need to understand some of the following terms about flooring and grinders:

1. The flatness of the ground: artificially smeared the leveled ground or the old ground with serious looseness and damage. It is necessary to level or remove the loose surface layer. It is necessary to use a high-power grinding machine and select a concrete diamond polishing pad to grind it. Suitable for leveling polishing pads. The level of flatness of the cement self-leveling floor or the trowel machine leveling is better. Only the diamond resin polishing pad can make a beautiful polished floor, and the polishing pad is also relatively economical.

2. Hardness of the ground: The concrete used in the design and construction of concrete floors is indicated by the number, which is C20, C25, C30, etc., which we usually talk about. The higher the number of normal concrete, the better the strength and hardness of concrete. However, due to various factors, the concrete marking and the ground hardness often do not correspond. The hardness of a concrete floor is usually expressed in terms of Mohs hardness. The hardness of the concrete floor is usually between 3-5. On the construction site, we can replace the Mohs hardness tester with some substitutes to understand the hardness of the ground: the hardness of the damaged scratches can be less than 5 by using nails and keys. Otherwise, Hardness is greater than 5.

3, the weight and speed of the grinder: floor grinders are usually divided into small, medium and large. Generally speaking, the larger the machine, the higher the power and the higher the efficiency. In actual use, the larger the machine, the better. The grinding machine with too large and too heavy is highly efficient, but it often leads to excessive grinding and increase. Construction costs. Experienced workers will adjust the machine speed, moving speed, number of polishing pads and machine weight according to the characteristics of the machine, reduce construction costs and improve construction efficiency.

4. Types and particle size of polishing pad: The most commonly used abrasives for floor treatment are PCD polishing pad, metal-based polishing pad and resin-based polishing pad. PCD polishing pad is used to remove thick coating on the floor surface. Metal-based polishing pad is used for Floor surface pretreatment and rough grinding treatment, resin-based polishing pad is used for surface rough grinding, fine grinding, fine grinding and polishing treatment. It refers to the size of diamond particles contained in the grinding tool. The lower the number, the larger the particle size.

PCD polishing pad is not divided into grain size, but it is directional, which should be paid special attention when using it; metal polishing pad is usually divided into several numbers such as 30#, 50#, 100#, 200#, etc. Which granularity number to use should be determined according to the ground conditions. For example, if the ground flatness is not good or the surface is loose, it may be necessary to use a 30# metal polishing pad to remove the loose surface layer to level the ground. The ground that needs to make a matte and grindstone effect is usually required. Use 50# or 100# metal polishing pad; resin polishing pad is widely used, grain size No. 30#-3000#, different grain size numbers are distinguished by different color adhesive cloths, used for ground rough grinding, fine grinding, fine grinding and polishing. Treatment, resin polishing pad has the difference between hard polishing pad and soft polishing pad. Hard polishing pad has better leveling effect. It is more suitable for medium and large floor grinding machines. Diamond soft polishing pad has better polishing effect and is suitable for various kinds. Type of floor grinder.

Hard concrete floors are recommended to use soft base metal polishing pads, use sharp resin polishing pads, increase machine weight, reduce mill speed, and reduce forward speed.

Soft concrete floors are recommended for hard metal polishing pads, durable resin polishing pads, increased mill speed, and faster forward speeds.

The quality of the domestic concrete floor is mostly not ideal, especially the renovation of the old ground, the flatness is not good, the ground is loose, the hardness is very poor, the water mill process produces a large amount of mud, and the abrasive consumption is particularly severe. On such a ground, it is recommended to use medium and large ground. Ping grinding machine, after shaving and dry, use dry dry grinding, first select 30# hard base metal polishing pad to remove loose layer to leveling treatment, then use 100# medium hard or soft base metal polishing pad to grind, flatness and foundation The hardness is handled well, and the back is much simpler.

Second, the correct choice of polishing pad benefits

The correct selection of polishing pad can improve the efficiency and reduce the cost. The selection and use of the polishing pad are regularly followed: the ground leveling and rough grinding use diamond polishing pad or concrete thick polishing pad; the fine sand polishing pad can handle the good without coarse sand. Polishing pad; increasing the weight of the grinder or increasing the speed can improve the efficiency; try not to use the polishing pad with the skip number; the dry grinding saves the consumables more than the water grinder, but the water grinding treatment will make the ground more even and delicate; wash the floor and dry it after use The thin polishing pad has a better effect of high-speed dry polishing; the use of a sponge polishing sheet can improve the brightness of the floor.

Diamond polishing pad available range, use and maintenance methods

Diamond polishing pads may not directly touch us in life, but many of the stones we use, such as tiles, marbles, etc., are all made by diamond polishing pads, forming a particularly beautiful form to present to us.

Diamond polishing pad, also known as diamond soft-grinding pad, is a flexible processing tool made of diamond as an abrasive and combined with composite material. The back is affixed with Velcro cloth and fastened to the joint of the mill.
It can be used for grinding, and can be used for stone, ceramic, glass, floor tile and other materials. It is suitable for stone polishing, line chamfering, curved plate and special-shaped stone processing. It can also be used for marble, coagulation, cement floor, terrazzo, Shaped processing, repair and refurbishment of glass-ceramics, artificial stone, floor tiles, glazed tiles and vitrified tiles.

The diamond polishing pad has strong grinding force, good durability, good softness, good definition, good gloss, no scratches on the stone after grinding and polishing, and color left (not easy to dye), high wear resistance and long service life. It is an ideal stone grinding tool. The whole process is divided into four stages: rough grinding, fine grinding, fine grinding and polishing. The processed stone has a gloss of more than 90°.

Diamond polishing pad available range

Diamond polishing pad is one of the most commonly used grinding blades, because polishing pads of different sizes can be selected according to different grinding materials, which can be used for grinding such as fine grinding, rough grinding and polishing, and can also be used according to different needs. And with the habit of matching different refurbished machines, according to different grinding materials and grinding methods to carry out the corresponding processing, and finally achieve the desired effect. Because the diamond polishing pad has a relatively complete grain size and good flexibility, it is more convenient to use in the processing of special-shaped stone such as marble and granite.

1. It is used for stone processing such as artificial stone, granite and marble. It has complete standard grain size and good flexibility. It is handy for line, chamfer, curved plate and special-shaped stone processing. It has various shapes and specifications. Various grain size numbers are easy to distinguish. Tianbang diamond polishing pad can be flexibly matched with various hand grinders according to needs and habits.

2. It can be used for the treatment and renovation of various floors and steps after laying granite, marble and artificial stone plates. It can be flexibly matched with various hand grinders or refurbished machines according to needs and habits.

3. For the grinding and polishing of ceramic tiles, the tile manufacturer is equipped with manual, automatic full-throwing machine and semi-polishing machine for the full-throwing and semi-polishing treatment of microcrystalline bricks, glazed tiles and antique bricks. The brightness of the smooth surface can reach more than 90; it can be used for ground treatment and refurbishment of microcrystalline bricks and various ceramic tiles. It can be flexibly matched with various hand grinders or refurbished machines according to needs and habits.

4. Tianbang diamond polishing pad can be used for refurbishing the concrete floor, warehouse, parking lot and other concrete floors or various aggregate hardener floors, especially the popular liquid hardener floor project, which can be flexibly according to needs and habits. Used with a variety of hand grinders or refurbished machines, DS grinding discs of different sizes are used for rough grinding, fine grinding and polishing.

Diamond polishing pad use method

The diamond polishing pad is suitable for portable electric or pneumatic mills, and then the joint is connected, the power is 750-1500W, and the number of revolutions is 2000-10000 rpm. When working, the water is applied to the machine by a certain pressure on the surface of the stone to be polished 4-5 times, and the finer number one grinding piece can be replaced. Many people are accustomed to using polishing pads, because the polishing pads are deeper, they are less prone to scratches and there is no dust. The dry grinding is relatively shallow, the dust is relatively large, and the scratches are more likely to occur.

Diamond polishing pad maintenance

1. Regularly carry out dust removal and cleaning work of Tianbang diamond polishing pad to ensure the normal cleaning of diamond polishing pad is also very beneficial to the removal of gravel;

2. Clean up the spill in time, and never leave heavy objects, or coffee and alcohol, on the diamond polishing pad for a long time;

3. The sand will be removed in time, and the gravel will directly cause the surface of the Tianbang diamond polishing pad to wear. Whether it is indoors or outdoors, the dusting mat should be laid, which can prevent the gravel from entering the room more effectively;

4. Must use a relatively high quality sealant to seal the diamond polishing pad, because the seal will help the natural appearance of the diamond polishing pad, but also effectively enhance the appearance of dark light on the surface, but also play appropriate The ability to resist pollution.

Marble polishing pad polishing process

Because of the long-term use of marble, the crystal surface brightness and gloss disappeared on the marble surface, which affects the overall decoration design inside the home. Then, when the brightness and gloss of the crystal surface of the marble disappear, what method can be used to make the marble crystal surface Re-glowing? Generally in this case, we need to polish the marble to re-gloss the crystal face of the marble.

Then, when we polished the marble, we prepared some tools before polishing, and prepared terrazzo, marble polishing machine, diamond disc, polishing powder, stone crystal machine and so on.

Marble polishing process

1. Before performing the marble polishing work, first check the shape of the marble used to see if the decorated marble material conforms to the shape of the processing sheet, and then the polishing and polishing process of the marble, first of all, the marble For the place to be glued, it is necessary to wait until the glue is processed before polishing and polishing.

2. The first is to make a single-piece drawing line for rough grinding, usually it is to leave it 0.5MM fine grinding, water mill is also the same; after completion, it is splicing, mainly to match the polished and polished lines, and then based on The color of the surface of the line is correspondingly adjusted, so as to ensure the color of the marble surface and the good pattern effect. After the line water mill 500#, the number is first unified according to the requirements of the installation drawing, and then the polishing is disassembled. This will not cause the polished and polished lines to be concave and convex at the interface.

3. When there is a misalignment at the interface, the grinding of the transition section should be extended, the longer the better, and the straightness should be checked by the ruler during the grinding; the finished polishing line can be shipped after passing the quality inspection.

4. After the sanding is completed, use the water absorbing machine to treat the moisture on the ground. At the same time, use the blow dryer to dry the whole stone floor. If time permits, you can also use natural air drying to keep the stone surface dry.

5. Spray the syrup evenly on the ground side, use a marble polishing machine to grind, use a washing machine with a scouring pad, spray the syrup with the same amount of water on the ground, start grinding, and make the crystal surface material on the stone surface under the action of heat energy. The surface effect formed after crystallization.

6. Overall ground maintenance treatment: If the stone with large voids is to be coated with marble protective agent, re-polishing once to increase the hardness of the crystal surface of the entire ground.

Generally speaking, the above steps can basically treat the marble surface well, but sometimes we encounter artificial stone like jazz white and resin. After doing it, the surface may not be very bright, we can spray A2 again. The syrup is ground to 3000#, then repeated with nano-pad, with marble mirror complex cream NO2, 2X mirror lock bright knife into the milk Q5 for polishing, the effect of water bright will be much better than before.

Marble polishing precautions

When polishing marble, we use different polishing and polishing processes according to the type of marble, and the polishing process of the flat plate is different from the polishing process of the arc panel. We should pay attention to the following points when polishing and polishing.

1. When polishing and polishing, each abrasive or abrasive sheet should be carefully inspected and polished to the polished surface after grinding and polishing. After the grinding, the latter should cover up the traces produced by the previous abrasive.

2. Polishing and polishing should pay attention to the control of the amount of water, the lack of water is easy to cause the surface to burn.

3. When polishing and polishing, try to lengthen along the direction of the line, as long as possible, so as to avoid the generation of ripples.

4. The speed of polishing is faster.

5. Processing large quantities of lines polished or polished is better to use a forming knife, this can reduce the amount of rough grinding work, and ensure that the line after rough grinding of good quality, shape consistency.

What are the renovation procedures for marble polishing pads?

As more and more stone is applied to the decoration project and enters people’s daily life and work, people put forward higher requirements for the decorative effect of the stone. “Stone needs nursing” is increasingly accepted by people, and stone conservation has become an important part of the process of building decorative stone.

First, marble polishing pad renovation

Renovation of marble polishing pad is to renovate the marble floor, wall (or exterior wall), countertop, column and other marble plates without any seams, pollution, weathering, holes, no light, etc. Nursing machines, tools, etc. are cleaned, polished, and polished to restore the same luminosity as before the initial installation and to make the marble surface more visible.

The refurbished marble polishing pad has the following four effects:

1. Increased hardness: After treatment, the surface is not dusty, wear-resistant and scratch-resistant, and prolongs the service life of the stone floor.

2, mirror effect: the surface of the terrazzo can reach the same luster of natural stone, and the finish is high. The luminosity can reach 105°.

3, good anti-fouling: corrosion resistance, oil, water, anti-seepage, anti-fouling, water absorption is less than 0.5%.

4, easy maintenance: daily cleaning, maintenance is easy, greatly reducing the cost of cleaning and maintenance in the later period, daily use only dust push with electrostatic vacuum dust, regular neutral detergent cleaning or stone care solution polishing marble board.

Second, the marble polishing pad renovation step procedure

Natural marble, also known as marble, is mainly composed of calcium carbonate and magnesium, sodium, silicon, etc. The hardness of the friction type is about 4 or 5, which is soft. It is less resistant to weathering, so it is easy to lose luster on the worn surface. We can choose to carry out light, medium and deep stone renovation according to the degree of stone surface wear.
The equipment, accessories and consumables required for marble renovation are: ordinary weighting machine, 4 inch diamond water-grinding disc, 17-inch refurbished disc, water absorbing machine, signboard, watering can, glass scraping, water wiper and bucket.

1. Marble polishing pad is lightly refurbished

The surface of the stone is slightly scratched and can be refurbished with a mild refurbishment process. If there is old wax on the ground, first wax, then use 800# diamond water grinding disc and clean water for 10 minutes. Note: add water in the grinding process to keep the ground moist, and use suction machine to absorb the sewage to prevent the second pollution of sewage. ground. Then change 1500#, 3000# polished sheet, diamond water-grinding sheet, and polish one by one by the above method. After the refurbishment process is completed, the water on the surface of the stone is washed with water and the surface of the stone is gently refurbished.

2. Marble polishing pad moderately refurbished

When the surface of the stone loses its luster, it can not reflect the object at all, but it has no deep scratches. It can be refurbished by a medium refurbishment process. Polished pieces of 200#, 400#, 800#, 1500#, 3000# and diamond water-grinding pieces were polished one by one. The grinding method and precautions were consistent with the above.

3. Marble polishing pad depth renovation

When the surface of the stone is holed, weathered, severely corroded, completely tarnished and deeply scratched, it can be refurbished by a deep refurbishment process. Before renovating, the holes should be repaired as follows: first clean the dirt in the holes, then dry the stone, and use imported epoxy resin or unsaturated resin glue according to the color and reflective characteristics of the original stone. After the coloring, the repair was carried out, and the weighting machine, the new plate and the 50#, 150#, 200#, 400#, 800#, 1500#, 3000# polished diamond water-milling pieces were used for one-by-one polishing. The grinding method and precautions are consistent with the mild renovation.

If marble crystal hard powder is used for hard treatment of stone crystal, in the process of refurbishing, after grinding with 800# diamond water grinding sheet, the crystal hard powder can be directly used for crystal hard treatment, and the surface of the treated stone is as bright as new.

Concrete polishing pad use method

The concrete polishing pad is specially formulated and used for the grinding and polishing treatment and renovation of concrete floors, warehouses, parking lots and other concrete floors, cement self-leveling floors, various aggregate hardener floors and liquid hardener floors.

1, base surface treatment: the ground water is fully immersed, and the loose surface layer is fully washed with a high-pressure washing machine or a refurbished machine with a hard brush, and the hollow drum portion is treated separately;

2, damage repair: use the water suction machine to absorb the surface water, apply the interface agent, use the repair materials that meet the requirements to repair and maintain according to the specifications;

3, leveling: use TFP series concrete floor polishing pad or metal polishing pad (water mill or dry grinding);

4, rough grinding: use 50#-200# series concrete floor renovation tablets;

5, infiltration treatment: according to the standard use of concrete liquid hardener hardening treatment, if the original ground hardness is poor, it is recommended to do an infiltration hardening treatment before rough grinding;

6, fine grinding: use 200#-300# series concrete polishing pad. If the hardness of the ground after the osmosis hardening meets the construction requirements, sanding will not occur during fine grinding;

7, fine grinding (rough polishing): use 500#-1500# series concrete polishing pad;

8, Washing and drying: thoroughly clean the floor with a refurbished machine with a cleaning pad, and dry it with a water suction machine;

9, penetration. Varnishing: use concrete permeable brightener or similar products, pay attention to different processing techniques of different products;

10, fine polishing: use concrete polishing pad 3000# (select 1-2 particle sizes as needed).
The new ground infiltration treatment suggests that the infiltration treatment is carried out after “fine grinding”. If sanding occurs on the ground during fine grinding, it is recommended to do an infiltration hardening process before fine grinding.

Precautions:

1. According to the needs and experience, choose different types of refurbished machines and polishing pads. The grinding effect will be affected by various factors: ground hardness, grinder weight, counterweight, rotation speed, whether water and water quantity, polishing pad type, quantity, polishing Pad size, grinding time and experience, etc.;

2. According to the ground hardness and technician experience to choose different grain size polishing pad, available for selection of granularity number including 30#, 50#, 100#, 150#, 200#, 300#, 400#, 500#, 600#, 800# , 1000#, 1500#, 2000#, 3000#, etc.

3. Dry grinding, water mill using different formulations of polishing pad, water mill can reduce on-site ash and improve efficiency. The granularity numbers are: 30#, 50#, 150#, 300#, 500#, 1000#, 2000#, 3000#, according to the actual situation, the jump level can be selected, the use effect and the ground hardness, flatness, and the granularity number selected by the polishing pad grinding time, experience of use. In the whole process, rough grinding, fine grinding is more uniform and more thorough, and the fine and smooth light will be saved and polished in a more efficient way.

4. It is recommended to clean the ground before polishing the polishing pad for the next size. Otherwise, it will affect the grinding effect.

Introduction of polishing polishing technology for polishing pad

When many people renovate their homes, they usually renovate the floor of their homes and renovate the old tiles into new ones. Sometimes, this is not necessary. You can achieve this effect with a simpler method. Then, in detail, we will introduce the polishing and polishing technology of the polishing pad in detail, so that you can have a new look in the home without replacing the new ceramic tile.

1. The traditional construction technology has caused the polishing pad to be very rough and filthy. Even if it has not been delivered, it will be dirty, and it will cause serious obstacles to daily hygiene termite control. However, as time went by, there were very prominent problems in actual use: the polishing pad was weathered, abraded, stained, and dull. China has used nearly 5 billion square meters of polishing pads in buildings. How the floor refurbishment film restores the weathered and abraded polishing pad to its original beauty and beauty is an increasingly urgent problem to be solved in the building decoration industry.

2. Facing the weathering and abrasion of the polishing pad, the only way at home and abroad is to remove the dirt on the surface of the stone and apply a layer of wax. Many people think that after waxing, they can keep the tiles transparent. In fact, this method can only temporarily keep the tiles bright and bright, and the duration of the tiles is only one week, so this method is not feasible.

3. In order to re-form the protective film on the polishing pad floor, it is necessary to polish the polishing pad floor. The weathered, abraded aging layer of the polishing pad surface can be shaved with a polishing pad ground grinding machine to expose the fresh layer and then mechanically maintained.

After understanding the above knowledge, we know that after polishing the polishing pad polishing technology, I feel that this technology is quite good, but the effect is not very big, and the maintenance time is not very long, so the technology still needs to be improved. However, this is a very practical and simple and easy way to operate the ground.

How to choose polishing pad for concrete floor construction

The selection and use of polishing pads are very regular. The ground leveling and rough grinding should use diamond grinding discs or concrete thick grinding discs. Dry grinding is more material saving than water grinding, but the water grinding treatment will make the ground more uniform and fine. Wait, then when choosing a polishing pad, how should I choose? What factors will affect our choice? I will analyze it carefully with you today.

Commonly used concrete polishing pads mainly include the following: Polycrystalline diamond polishing pad: used to remove epoxy coating, which is needed when the coating is thicker;

Concrete diamond polishing pad: used for concrete floor leveling and old ground renovation;

Concrete thick polishing pad: usually refers to a diamond resin polishing pad with a thickness of 5mm or more, used for concrete floor leveling, rough grinding, fine grinding, fine grinding and polishing;

Thin concrete polishing pad: usually refers to a diamond resin polishing pad with a thickness of 5mm or less, used for rough grinding, fine grinding, fine grinding and polishing of concrete floors;

Concrete polishing pad: usually made of man-made fiber, wool or other animal hair, and some products are also added with abrasive and polishing accessories for polishing the concrete floor; how to choose and use such a variety of polishing pads Use it?

Flatness of the ground

Manually screed the leveling ground or the old ground that is loose or damaged. It needs to level or remove the loose surface layer. It needs to use a high-power grinding machine, choose a concrete diamond polishing pad and other grinding force, suitable for leveling polishing. pad. The level of flatness of the cement self-leveling floor or the trowel machine leveling is better. Only the diamond resin polishing pad can make a beautiful polished floor.

Ground hardness

The concrete used in the design and construction of the concrete floor is indicated by the number, which is C20, C25, C30, etc., which we usually talk about. In normal cases, the higher the number, the better the strength and hardness of the concrete, but due to various The influence of factors, the number of concrete and the hardness of the ground are often not corresponding. The hardness of a concrete floor is usually expressed in terms of Mohs hardness. The hardness of the concrete floor is usually between 3-5. On the construction site, we can use some substitutes instead of the Mohs hardness tester to understand the hardness of the ground: the hardness of the scratches and scratches can be less than 5 with nails and keys. Otherwise the hardness is greater than 5.

Grinder weight and speed

Floor grinders are usually divided into small, medium and large. Generally speaking, the larger the machine, the higher the power and the higher the efficiency. In actual use, the larger the machine, the better. The grinding machine with too much weight is very efficient, but it often leads to excessive grinding and increases. Construction costs. Experienced workers will adjust the machine speed, moving speed, number of polishing pads and machine weight according to the characteristics of the machine, reduce construction costs and improve construction efficiency.

Type and size of polishing pad

The most commonly used abrasives for floor treatment are PCD polishing pads, metal-based polishing pads and resin-based polishing pads. PCD polishing pads are used to remove thick coatings on the floor surface. Metal-based polishing pads are used for floor surface pretreatment and rough grinding. Resin-based polishing pads are used for rough grinding, fine grinding, fine grinding and polishing. Particle size refers to the size of the diamond particles contained in the abrasive tool. The lower the number, the larger the particle size.

The PCD polishing pad is not granular, but it is directional, so pay special attention to it when using it.

Metal polishing pads are usually divided into several numbers such as 30#, 50#, 100#, 200#, etc. Which granularity number should be determined according to the ground conditions, such as poor ground flatness or loose surface, may need to use 30# The metal polishing pad removes the loose surface to level the ground. The ground that needs to be sanded or grinded usually requires a 50# or 100# metal polishing pad.

Resin polishing pad is widely used, grain size No. 30#- 3000#, different grain size numbers are distinguished by different color adhesive cloths, used for ground coarse grinding, fine grinding, fine grinding and polishing; resin polishing pad has hard polishing pad and soft The difference between the polishing pad and the hard polishing pad is better. It is more suitable for medium and large floor grinding machines. The soft polishing pad has better polishing effect and is suitable for various types of floor grinding machines.
