Stone dry grinding or water grinding, what is the difference?

Dry stone grinding, as the name implies, does not add water when grinding stone. Adding water when grinding is called water grinding. What is the difference between the two? When is the dry grinding? When is the water mill?

1. What is the difference between dry grinding and water grinding?

1, the polishing pad is different

The mainstream polishing pads currently on the market are mostly made of synthetic diamond particles and resin binders. Diamond is the diamond we usually say, and resin, in a broad sense, is a general term for a variety of high molecular polymers that can be used as plastic raw materials.

When the stone is grinded, the grinding piece and the surface of the stone are rubbed, and the high temperature is instantaneously generated under the speed and pressure of the machine rotation. This temperature can melt the general resin, and the inferior polishing pad is easily deformed and distorted when it is ground for this reason. Adding water to the stone water mill can accelerate the heat dissipation, and the requirements for the polishing pad composition are slightly lower, while the dry grinding does not add water, and the heat is emitted slowly. Therefore, the resin used for the dry polishing pad must select a high-quality resin with high temperature resistance.

Dry polishing pad with high temperature resistant resin

Simply speaking, due to the composition, the dry polishing pad can be water-grinded, but the ordinary polishing pad can not be dry-grinded for a long time. The grinding plate made of high-quality resin can be dry-grinded or water-grinded.

2, water mill damage to the stone is less

The high temperature generated during the grinding of the stone can cause certain damage to the structural crystal of the stone. Stones are burnt at high temperatures, which are prone to a series of problems such as loss of light, chipping, and chalking.

The reason is the composition of the stone. The main component of the marble is calcium carbonate. Calcium carbonate is converted into calcium oxide after being calcined at a high temperature, which is the so-called firing process of lime.

Chemical reaction type: CaCO3 (heating) = CaO + CO2 (gas) When adding water to the stone, it can accelerate the heat dissipation and reduce the damage to the stone.

3, the gloss of the water mill is more soft and beautiful

During the grinding and polishing process of the stone, all the light emitted by the high temperature is different from the light thrown out at the natural temperature.

The luster that is thrown out at natural temperature looks bright and bright, and under high temperature conditions, the heat generated by the friction moment has a certain destructive effect on the crystal structure of the stone, so the gloss produced by the dry grinding has glare and burning. Eclipse, dry, not transparent.

Generally, when black stone is ground, it tends to be white, and water mill is better than dry mill. The beige stone is dry-grinded all the way, and the color is not transparent, the bright is bright, but the gloss is dry and faint, which is due to the high temperature ablation during grinding.

The heat generated by dry grinding is harmful to any stone. It is not obvious on white or beige light stone, but it is especially noticeable on black stone. Therefore, dark stone, relatively transparent jade, etc., it is best to grind.

4, the pollution caused by dry grinding is difficult to handle

Dry grinding produces dust, which is mostly flying in the air, and a small amount is dissolved or absorbed into the holes of the stone. These extremely fine stone powders enter the interior of the stone to absorb moisture and absorb moisture, which will pollute the stone for a long time.

Flying dust in the air is very detrimental to the health of stone caregivers. Moreover, the dust generated during dry grinding is difficult to handle. The dust generated during the grinding process of the stone is very delicate and can produce a floating effect. As the mesh size increases, the fineness of the dust increases exponentially, and the dust volume becomes larger and larger. It is very difficult for you to deal with these dusts in the city.

Second, when does the stone dry grinding?

1, no protective stone

Stones that have been glazed, mirrored, or heavily aged on the surface need to be opened before the protective agent is applied. The specific method is to grind the crystallization, sealing layer or aging layer of the surface to facilitate the grinding. Absorbent absorption.

Stone coating protective agent, in order to achieve good results, requires the stone to be clean and dry, the stone that has not been protected is easy to absorb water. If the surface of the stone is opened by water grinding, the water absorption will extend the construction period.

Therefore, if there is no protective stone, the surface can be opened by dry grinding before applying the protective coating.

2, grinding and polishing

The stone grinding leveling and grinding optimization step uses water grinding, and in the grinding and polishing process, the light is accelerated by the dry grinding. The specific method is to grind to 1000 mesh by water grinding. The stone can be added with little or no water to semi-dry or completely dry. In practical applications, it is found to be a practical technique to help the stone.

The reason is that during the low-stage water mill, the stone has absorbed water and the ground is moist. Therefore, it can be dry-grinded after 1000 mesh, and the heat of dry grinding can also accelerate the evaporation of water, and the stone is dried in advance, which is the crystal seal of the latter. Glaze operation saves waiting time.

3, wall, corner, countertop

The wall must be dry-ground because the wall does not have water-grinding conditions. The finishing work after the stone is finished, such as the wall and the corner where the large machine is out of reach, can be carried out by dry grinding. As well as lines, small areas of enamel, repairing countertops, etc., dry grinding is more convenient.

Dry grinding is not absolutely without adding water. If the dark stone is dry and whitish during the grinding process, you can add a little water during the grinding, which will be better.

How to renovate granite floors?

The granite texture is hard and the color is beautiful. It is a high-quality building stone. The compressive strength varies according to the type of stone and the origin. Granite is not easy to weather, beautiful in color, and it can be connected for more than 100 years. Due to its high hardness and wear resistance, it is used for building decoration engineering, hall floor, and open-air carving.

Granite and microcrystalline stone flooring are hard to wear, but through long-term use, especially the erosion of outdoor acid rain, thermal expansion and contraction in summer and winter, weathering and dip, granite and microcrystalline stone floors will also lose their luster or even damage. Therefore, grinding, refurbishing, and maintenance will not be small.

First look at the general situation of the granite to determine whether it needs to be refurbished. If it is not necessary to renovate, it should be chemically restored to its revival. If it needs to be refurbished, it must adopt the correct refurbishment method.

Granite renovation process:

(1) First set the construction mark at the construction address to clean the granite floor that needs to be refurbished.

(2) Rough grinding: use 50#, 150# granite floor polishing pad or diamond bitter 60#, 120#, 220# grinding block (rough grinding, do not use soft polishing pad for grinding, easy to present sea waves, affecting flatness The coarse grinding water supply should be large, and the water should be thoroughly absorbed after each abrasive grinding. Check whether the deep scribe left by the cutting abrasive is ground with 50# abrasive, and so on, mechanical grinding, coarse grinding, and overall grinding. % time is the key link to ensure the completion quality inspection of Chengdu cleaning project.

(3) Fine grinding: using 300#, 500#, 1000# granite floor polishing pad, fine grinding accounts for 35% of the whole research time, after fine grinding to 500#, there is initial light, fine grinding to 1000#, the gloss is up to 50 degrees.

(4) Fine grinding: using 2000#, 3000# granite floor polishing pad for grinding and fine grinding, which accounts for 20% of the total grinding time. After finishing, the gloss is not promoted, but the density of granite and microcrystalline stone is improved. Polishing powder A5, polishing slurry (A2A5 blending agent) lay a solid foundation.

(5) Polishing: using a power of 2HP or more, a rotational speed of 175–210 rpm, a weight of 45 70 kg of crystal face machine, a hairy pad of 70%, a 3M pad, a nano pad, a common polishing powder A5. A2. Or polishing slurry (A2A5 blending agent for polishing and polishing, polished granite, microcrystalline stone profile gloss of more than 90 degrees.

(6) Crystal hardening treatment: using crystal machine power 2HP or more, rotating speed 75–210 rpm, weight 45 70 kg common cleaning pad (white or red) 3M pad, nano pad, crystal surface hardener A2 The watering can is evenly sprayed on the granite and microcrystalline stone profiles, and the starting crystal plane is 1.5 meters wide and 1.5 meters long. It is repeatedly moved 6 times round trip. Through the process of 3M pad, nano pad, friction on the granite microcrystalline stone, heat and crystal are generated. The hardener A2 performs ion exchange, forms a nanocrystalline polymer copolymer into a crystalline layer, is glassy, ​​has high hardness, wear resistance, transparency, and is resistant to water, stain, and slip.

Granite floor polishing pads have a complete and standard grain size color system and great flexibility. It’s easier to machine lines, chamfers, curved plates and shaped stones. The specifications are optional, the various particle sizes are easy to distinguish, and the various floors and steps of the paving are handled and refurbished. A variety of hand or refurbished machines can be used for a variety of grinding machines, depending on the needs and customization.

Grinding pad polishing technology

The polishing pad floor is a kind of composite floor material with cement as the main raw material. Its low cost and good performance are widely used in large-area public buildings. According to statistics from relevant departments, the use of public buildings exceeds 6 billion square meters, hospitals, pharmaceuticals, machinery, government agencies, schools, commercial sites, airport terminals and other terminals.

Polishing pad ground defects are mainly

1) It is easy to weather and aging, and the life cycle is 2-5 years;

2) The surface is rough, the gap is large, the stain resistance is poor, and it cannot be cleaned after being contaminated;

3) Even if the original waxing and maintenance method is used to improve the surface finish, due to the complexity of the operation organization, the cost is huge, but the result is not satisfactory;
For the above reasons, it is generally believed that the polishing pad is a medium and low-grade floor decoration material.

The traditional polishing pad has the advantages of low cost, free coloring and easy construction, and has a huge market. The polishing pad used in various urban and rural buildings has more than 10 trillion square meters. However, the traditional construction technology caused the polishing pad to be very rough and filthy, and even dirty when it was not delivered, it also caused serious obstacles to daily hygiene.

However, as time went by, there were very prominent problems in actual use: weathering, abrasion, stains, and dullness. How to restore the weathered and abraded polishing pad to its original beauty is an increasingly urgent problem to be solved in the building decoration industry.

Grinding pad polishing technology

In the face of weathering and abrasion, the only method at home and abroad is to clean the surface of the stone and apply a layer of wax. This method can protect the new surface and delay the natural weathering and abrasion speed. However, for the weathered and abraded polishing pad surface, the effect is the same as the varnish on the surface of the decaying wood. It is impossible to reproduce a beautiful, mirror-like fruit. Moreover, the wax film thus formed has a poor durability, and it is only necessary to keep the wax on the left and right again. Not only is the construction frequent, but the cost is high. The cost of cleaning and waxing per square meter per year is as much as several hundred yuan. Cleaning and waxing is the only method that every cleaning company can’t cope with customers. It can neither cure the symptoms nor treat the root cause.

The reason why cleaning waxing is not the real stone floor treatment is that it does not really solve the technical key of polishing pad processing. The reason why the polishing pad is as bright as mirror and crystal clear is that the polishing pad forms a layer of glass film on the surface after machining. This film not only has a mirror gloss, but also transparently shows the inner structure of the stone. The observed pattern is bright and beautiful. The key to rejuvenating a weathered, abrasive polishing pad is to re-form a vitreous film on the surface of the polishing pad.

The technical principle of the polishing pad ground grinding and polishing machine is: the weathered and abraded aging layer of the polishing pad surface is removed to expose the fresh layer, and then the complex effect is formed on the surface of the polishing pad by a mechanical method to form a new glassy film, thereby Restore the natural bright decorative fruit of the polishing pad. The entire process consists of multiple processes without any chemicals.

Solve the problem fundamentally, make the rough and dirty polishing pad smooth and bright, cure the symptoms and cure the problem, and achieve the mirror fruit. The cost of refurbishment is low. The construction is free from pollution, dust, mud splash or noise. For example, shopping malls and hotels can be operated while construction. The traditional ground construction process can be changed. For example, the ground can be first laid or firstly polished and then polished. Not only can the cost be reduced, but also the seams in the construction can be eliminated.

Crystal siliconizing technology for polishing pad

The principle of “Crystal Silicon Infiltration” is to seal the visible and invisible pores on the surface of the polishing pad with a mixed filler of modified resin and silicate powder, and form 0.5 mm silicate crystals on the surface, and the combination of silicone and silica. Body, so that the ordinary polishing pad meets or exceeds the fruit of the medium and high grade imported marble.
The polishing pad “Crystal Silicone” technology is suitable for the retrofitting of old polishing pads and the surface modification of newly made polishing pads, which improves the comprehensive performance index of traditional polishing pads.

After polishing pad modification, there are the following points:

1) The surface finish is high, it can reach 90 degree gloss unit, and the height can reach 98 degree gloss unit, which is equivalent to the quality of imported high-grade marble surface.

2) The surface has a hard height of 5-7, which is close to the surface of high-hardness granite and has good wear resistance.

3) Anti-infiltration, waterproof and anti-fouling (water permeability is less than 0.8), oil resistance, weak acid, alkali, salt spray resistance, the comprehensive performance of natural protection exceeds all current stone products.

4) The service life is up to 30 years. The special formula and structural design ensure that the “Crystal Silicone” board is easy to repair after being put into use, and the maintenance cost and hygienic management difficulty for the floor are greatly reduced.

What are the precautions for using the polishing pad?

The polishing pad has a uniform and standard grain size and good flexibility. It is widely used in the processing of marble, artificial stone and other lines, veneer curved plates and special-shaped stone. It has multiple shapes and different granularity. Colors can be distinguished according to the different needs of customers. Therefore, it is not enough to use only polishing pads. The following aspects also need to be noted:

1. When abnormal sounds and vibrations, rough cutting surfaces or odors are found, the work must be terminated immediately, and the fault should be checked and eliminated in time to avoid accidents.

2. When working, the workpiece should be fixed, the profile should be oriented with the direction of the tool to avoid abnormal cutting, no side pressure or curve cutting, smooth knife feeding, avoiding the impact of the blade and the workpiece, resulting in saw blade damage, or workpiece Flying out, causing an accident.

3. When cutting and stopping cutting, do not be too fast to avoid broken and broken teeth.

4. If cutting aluminum alloy or other metal, use special cooling lubricant to prevent the saw blade from overheating, causing damage such as paste and affecting the cutting quality.

5. The equipment discharge slag tank and slag suction device ensure the smooth flow of water, prevent slag agglomeration and affect production and safety.

6. Dry cutting, do not cut for a long time, so as not to affect the service life of the saw blade and cut fruit; when cutting wet, it should be cut with water to prevent leakage.

What are the uses of these various specifications of polishing pads?

1. Suitable for the processing of artificial stone, granite and marble. It has a complete and standard granular color system and great flexibility. It’s easier to machine lines, chamfers, curved plates and shaped stones. The specifications are optional, the various particle sizes are easy to distinguish, and various grinding machines can be flexibly configured according to needs and customization.

2. Handling and refurbishing various floors and steps of granite, marble and artificial slabs, and flexible use of various hand or refurbished machines according to needs and habits.

3. For the grinding and polishing of ceramic tiles, the tile manufacturer has manufactured a complete set of manual, automatic, semi-dispersing machines for semi-polishing and polishing of microcrystalline bricks, glazed tiles and antique tiles. The brightness of the illuminated surface can reach more than 90. Floor treatment and refurbishment for microcrystalline bricks and various tiles. It can be used flexibly with various grinders or update machines according to needs and habits.

4. The water mill can also be applied to the renovation of industrial floors, warehouses, parking lot concrete floors or various aggregate hardener floors. It is also the popular liquid curing agent floor project, which can be flexibly used according to needs and habits. Same size DS grinding machine for rough grinding, fine grinding and polishing.

The water grinder is suitable for hand-held electric or pneumatic mills with a joint power of 750-1500W and a speed of 2000~10000 rpm. When working, the pressure applied to the machine by the water can be reciprocated 4-5 times on the surface of the stone to be polished. It is possible to replace the finer grinding piece. I believe that after understanding the aspects that need attention, the polishing pad can be used more flexibly and with peace of mind.

What are the treatment methods for concrete polishing pads?

Concrete polishing pads are divided into diamond polishing pads, concrete thick polishing pads, concrete thin polishing pads and concrete polishing sheets. They are usually used on refurbished machines or floor grinders. Different models and sizes are selected according to the matching machine and ground hardness. Water polishing pad or dry polishing pad for floor leveling, rough grinding, fine grinding, fine grinding and polishing.

Leveling treatment:

1. Remove the loose surface layer of the old floor: Use the diamond polishing pad to easily remove the loose surface layer of the floor, and use it for medium and large floor grinding machines.

2. The flat surface treatment of poor flatness: first use the diamond polishing pad to initially level, and then use a thick polishing pad rough grinding and leveling, and then choose the appropriate concrete thick polishing pad or thin polishing pad grinding.

3. Surface treatment of large-area repairing floor: It is recommended to use the diamond polishing pad to grind and level before the surface is cured. After curing, use a thick polishing pad to roughen the leveling. Accurately grasp the grinding time to make the floor treatment simple and easy.

4. Surface treatment of old floor with good flatness: Selecting the thick polishing pad with the appropriate grain size according to the ground hardness can make the ground flatness better, and the later grinding and polishing process will be faster and better.

Rough grinding treatment:

1. After the ground leveling treatment, select a higher-grain size thick polishing pad or a thin polishing pad for coarse grinding, and use it for medium and large floor grinding machines.

2. Terrazzo floor, concrete color sand floor, uniform dry sand hardening agent floor: according to the floor hardness selection thick number of thick polishing pad, supporting medium and large grinding machine can improve the grinding rate and make the ground flatness better .

Fine grinding and fine grinding:

1. The new aggregate hardener floor keeps the surface of the puree: It is better to choose a thin concrete polishing pad suitable for fine grinding. A new floor with good mechanical light is easy to make a uniform surface of the pure pulp.

2. Ground after rough grinding: Select the concrete polishing pad suitable for fine grinding, thick polishing pad and thin polishing pad are applicable. The medium and large grinding machine can improve the grinding rate and make the ground flatness better.

Polishing treatment:

Concrete polishing should be carried out after fine grinding or fine grinding on the ground. Before polishing, the floor should be washed and dried, and dried with a thin polishing pad. The polished fruit is related to the hardness, flatness and pre-treatment of the ground.

Use a thin polishing pad to dry and then use a concrete polishing pad to polish, which can significantly improve the brightness of the ground.

Crystal surface treatment:

If the ground brightness requirement is high, it is recommended to perform crystal face treatment after polishing. Use concrete brightener for floor surface treatment. After spraying concrete brightener, use 6000# concrete polishing sheet (4FP6) to dry and throw, which is easy to bring long-lasting and charming mirror fruit.

Polishing pad life and grinding fruit will be affected by various factors, including ground hardness, grinder weight, counterweight, speed, whether water and water, polishing pad type, quantity, particle size, grinding time and experience. The thin concrete polishing pad can be used with a variety of refurbished machines and grinders. The thick concrete polishing pad is suitable for medium and large grinders to improve the grinding rate and make the ground flatness better.

Concrete polishing pads are divided into water polishing pads and dry polishing pads. Different formulations are used in different ways. Please choose according to the construction method.

What are the mirror stone maintenance steps?

Stone mirror maintenance is based on the improvement of hardness, gloss, lack of clarity and cumbersome process of water wax. The principle is to use the mirror treatment agent plus the heavy-duty processor to rub the stone surface. Under the dual action of chemical and physical, the stone surface layer forms a hard and dense crystal hard crystal layer, which makes the stone surface not easy to be damaged and not easy to stick. Stains, thus ensuring the essence of the stone, is one of the common stone conservation methods.

In other words, the crystal layer separates the source of pollution from the stone, and the only layer of crystal on the stone is contaminated and damaged. After the mirror treatment, the stone surface molecules are denser and the gloss brightness is obviously improved, making the stone surface brighter and more noble. Mirror processing accumulates fruit and value during constant maintenance.

The specific steps of stone mirror processing are as follows:

1. Finishing the surface of the stone floor: Before the crystallization treatment of the stone floor, the surface of the paving is completely flat, no color difference, the diagonal of each stone is flush, the whole ground is cleaned, and the ground is cleaned with dry and clean. There are no sand and impurities on the ground.

2. Stone gap marble glue repair: the overall cleaning is completed, use marble glue to repair small spots on each stone, the gap between the stones, use a small trowel to repair with marble glue, flat, use small Clean the rags and clean the finished parts one by one. The gypsum powder in the travertine must be cleaned; after the marble glue is repaired, it must be dried until the next step.

The so-called jointless grinding process is to fill the gap between the adjacent slabs, which are similar to the slabs, and then grind and polish them with the use of tools and techniques. After being processed in this way, the slate will present a large piece of stone that is not divided as a whole.

3. The overall ground grinding: After the marble glue is dried, use the grinding machine to polish the whole ground, the overall horizontal grinding, focus on the caulking between the stones (the diagonal between the stones) and near the wall, decoration At the edge of the shape and shape, keep the whole stone floor level, finish the grinding, re-cast the marble glue caulking, continue the second grinding with the caulking, and then use the platform refurbished machine with the diamond polishing pad from the coarse To fine, (150 mesh, 300 mesh, 500 mesh, 800 mesh, 1000 mesh, 1500 mesh, 2000 mesh), a total of seven grindings are required. The final ground is smooth and smooth, and then polished with steel wool. The brightness required by the design (70 degrees), there is no obvious gap between the stones.

4. The ground drying treatment: sanding is completed, first use the water suction machine to the overall treatment of the ground moisture, while using the blow dryer to dry the entire stone floor, if the construction period allows, you can also use natural air drying to keep the stone surface dry .

5. Ground crystallization treatment: the ground side sprinkle K2, K3 syrup, while using a multi-purpose washing machine to rotate, use the washing machine with red scouring pad, K2, K3 syrup with the same amount of water sprinkled to the ground, using 175 rpm /min The rubbing machine load 45KG starts to grind, and the heat energy acts to make the surface material formed by the mirror material crystallization on the surface of the stone.

6. The overall ground maintenance treatment: If it is a large void stone (sandstone, travertine, etc.) to be treated with marble protective agent, 12 hours later, then use the scrubber to alternate K2, K3 syrup on the ground, That is, K2-K3-K2-K3-K2 is used five times, and then replaced with a white polishing pad, sprayed with a small amount of K1 syrup, and re-grinded to increase the mirror hardness of the entire ground.

7. Ground cleaning and maintenance: When the stone surface is formed into a crystal mirror surface, use the water absorbing machine to absorb the residue on the ground, moisture, and then polish it with a polishing pad to make the whole surface dry and bright as a mirror. If partial damage can be used for local maintenance. The construction can be completed at any time.

Tips: The choice of mirror agent is more important. If the mirror agent is not well selected, it will have symptoms such as water spots and efflorescence after mirror treatment. A good way to identify this inferior mirror is to make a mirror surface and spill water on the beach. After soaking for a few hours, dry it again. Inferior products will show obvious immersion marks or gloss loss.

Marble polishing steps, precautions and maintenance

Marble decoration is very common. It is often used for cabinet countertops or floor decoration. It has the characteristics of beautiful decoration and good wear resistance. Marble needs to be polished during use, otherwise it will affect the luster of the marble surface. So what are the marble polishing methods, what should be paid attention to in marble polishing, how to maintain after polishing, let’s take a look!

First, marble polishing step

1. Dry grinding

There are many steps in marble polishing, and it is also very complicated. First, the first step is dry grinding. The purpose of dry grinding is to peel the marble. Need to use stone refurbished machine, it can remove the stain on the stone surface, while grinding the pores of the stone.

2. Dealing with stone stains

Usually the marble surface has a lot of stains, so if you want to polish the marble better, you need to deal with the surface stains. If it is a more difficult to treat stain, it can be treated with some chemicals, and the stain is easily removed.

3. Waterproof

Waterproof treatment is also a good foundation for marble polishing. Waterproof treatment is mainly to prevent the wet grinding in the later stage. Some sewage is immersed in the stone, which will affect the polishing, and the sewage will affect the quality of the marble.

4. Slitting, caulking, etc.

In order to ensure the marble surface is very beautiful, slitting, caulking and uniform slitting are very important. The easiest way is to make up the glue. After the glue is added, it can easily achieve the beautiful effect.

5. Simple polishing

Simple polishing is actually very simple, it can be waxed, cleaned, and then polished with steel wool.

6. Surface crystallization

Use the crystal plane machine to match the scouring pad and the detergent powder, and make a good protective layer on the surface of the marble to prevent the stain from entering the inside of the stone. At the same time, it can also prevent scratching, and it can also be very good. Enhance the brightness of the stone. It is understood that this protection period is about one year.

7. Waxing

Waxing is also done to increase the brightness of the marble, but also to protect the surface of the marble. The waxing period is basically three months.

Second, what should I pay attention to when polishing marble?

1. After the marble is finished, the surface water should be treated with a water absorbing machine, and the stone floor should be dried by a blow dryer to keep the surface of the stone dry.

2. If the stone is polished with a large diameter grinding machine, then the grinding depth should be controlled between 1mm and 2mm, and the feed speed should be reduced. If the line speed of the stone grinding machine is large, a large depth of cut is required.

3. Marble grinding should pay attention to, if it is a large gap of stone need to apply a protective agent on the marble surface, and then re-polishing once to increase the hardness of the entire surface of the crystal face.

Third, how to maintain the marble after polishing

1. After the marble is polished, the pores of the stone are completely closed, and the lesion is prone to occur. Therefore, the polished marble needs to be treated for the crystal surface, so that the pores on the marble surface can be opened, so that the marble can be opened inside and outside. Breathable, and the crystal-treated marble is not prone to lesions, but also has a certain anti-fouling and waterproof effect.

2. After the marble is polished, after a period of time, it is necessary to remove the old wax layer with wax water. At this time, it is necessary to carry out large-scale construction, and do not carry out partial construction, otherwise there will be chromatic aberration after construction. Thereby affecting the beauty of the overall effect.

I would like to remind everyone that when cleaning the marble floor, it is best to use a neutral detergent. If a strong acid detergent is used, it will cause certain damage to the marble floor and even corrode the marble surface, causing more unnecessary trouble.

Marble polishing pad use

Marble polishing pads are believed to be familiar to everyone. Because marble floors are widely used in public places, shopping malls, supermarkets, etc., due to the large number of people, it is inevitable that the marble floor will wear out over time. At this time, marble polishing pads will be used, and the ground needs to be refurbished. When it comes to this, many people have already basically understood this product, but after all, there are still many people who are confused about the use of this product. Know how to use it to achieve the effect of ground renovation.

This article will detail and describe some of the considerations in the use and use of the polishing pad from each step used in the marble polishing pad.

1. Clean the surface of the ground. Use a tool to remove the concrete slurry from the gap in the stone. Then remove the dust thoroughly with a brush or a vacuum cleaner. Use a dry and clean ground to clean and clean the ground without sand and impurities.

2. After the overall cleaning of the stone surface is completed, the small damaged points and the stone joints on each stone are repaired with marble glue, and the original damaged surface is first repaired with marble glue close to the stone color. Then use the stone slitting machine to re-cut the slit in the original stone installation to make the width of the gap, and then fill it with marble glue close to the stone color. After the marble glue is repaired, it must be dried before the glue can be dried.

3. After the marble glue is dried, use the sander to polish the whole ground, and polish the whole horizontally. Focus on the caulking between the stones and the edge of the wall, the decorative shape and the special shape to keep the whole stone floor level. Finishing the polishing, re-creating the marble glue, caulking, caulking, and continuing the secondary grinding. Then use the stone refurbished machine with the steel stone polishing pad from coarse to fine. A total of seven polishing and finishing finishes are required. Smooth, and then polished with steel wool, the polishing degree reaches the brightness required by the design, there is no obvious gap between the stones.

4. After the polishing is completed, use the water suction 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 the enamel. Use a washing machine with a red scouring pad. Sprinkle the syrup with the same amount of water on the ground. Start grinding and heat. The crystal surface material is crystallized on the surface of the stone. The surface fruit formed after the transformation.

6. The overall ground maintenance treatment: If it is a large gap of stone to be treated with marble protective agent ‚ re-polishing times to increase the hardness of the entire surface of the crystal face.

7. Ground cleaning and maintenance: When the stone surface is formed into a crystal mirror, use a vacuum cleaner to absorb the residue and moisture on the ground. After polishing, use a polishing pad to make the whole surface dry and bright. If the surface is damaged, local maintenance can be performed. Construction can be done at any time.

Marble polishing pad has traditional and standardized grain color and good flexibility. It is widely used in the processing of marble, artificial stone and other lines, curved veneer and special-shaped stone. It has multiple shapes and can be used for various grain sizes. Different colors can be used to distinguish them according to different needs of customers. Therefore, it is not enough to use only polishing pads. In the following process, you should also pay attention to these aspects:

1. When abnormal sounds and vibrations, rough cutting surfaces or odors are found, the work must be terminated immediately, and the fault should be checked and eliminated in time to avoid accidents.

2. When working, the workpiece should be fixed, the profile should be oriented with the direction of the tool to avoid abnormal cutting, no side pressure or curve cutting, smooth knife feeding, avoiding the impact of the blade and the workpiece, resulting in saw blade damage, or workpiece Flying out, causing an accident.

3. When cutting and stopping cutting, do not be too fast to avoid broken and broken teeth.

4. If cutting aluminum alloy or other metal, use special cooling lubricant to prevent the saw blade from overheating, causing damage such as paste and affecting the cutting quality.

5. The equipment discharge slag tank and slag suction device ensure the smooth flow of water, prevent slag agglomeration and affect production and safety.

6. Dry cutting, do not cut for a long time, so as not to affect the service life of the saw blade and cut fruit; when cutting wet, it should be cut with water to prevent leakage.

The above is a complete introduction to the use of marble polishing pads. I believe that through the above introduction, we can use polishing pads more flexibly and safely.
