The floor is used frequently in the building, so it is easy to be damaged. Due to the limitation of process technology, many old floors (such as epoxy, emery, terrazzo, floor tiles, cement floor, etc.) gradually expose their defects, and there are differences. The problem of form and degree, so to a certain extent, it needs to be refurbished. Today, diamond water mill manufacturers will come to introduce you to several renovation construction techniques commonly used in industrial floor renovation.

Epoxy floor construction technology

1. Plain treatment: grinding, repairing and dust removal according to the condition of the plain

2. Epoxy Primer: Adopts strong epoxy primer roller coating to improve surface adhesion.

3. Epoxy approved soil: According to the actual needs of construction of several passes, it is required to achieve flat and no holes, no batch of knife and sand printing

4. Epoxy topcoat: two coats of solvent-based epoxy topcoat or anti-slip topcoat.

5. Construction is completed: people can be loaded after 24 hours, and pressure can be heavy after 72 hours. (25 ° C prevails, the opening time at low temperature needs to be moderately extended).

Concrete seal curing agent floor (mirror type) construction technology

1. Grass-roots treatment: before construction, clean and clear the sundries, oil, and curing agents on the ground. Cement-based repair mortar was used to repair the pits and cracks on the ground and cured for 3 days.

2. Grinding the ground: The surface quality is poor and rough: install a rough diamond module on a water grinder (7.5KW machine), add water to grind the ground, and after basic smoothing, change the fine grinding heads separately, and finely grind the ground, The same process is water milled) until the floor is smooth. After grinding the ground, clean the ground with water, and use a vacuum cleaner to suck up the sewage. For better, smooth new wear-resistant floors, you can directly apply concrete seal curing agent.

3. Brush concrete seal curing agent: After the floor is cleaned and the surface is allowed to air dry, brush concrete seal curing agent can be applied. Use a roller or sprayer to evenly apply the curing agent to the ground, and the average application amount is 10 ㎡ / kg. If the base surface is poor and has strong permeability, it must be painted twice after 1-2 hours; after about 1-2 hours (before the material is dry and shiny), spray some water on the ground to wet the material. Use a broom or a floor to scrub and wash the surface to allow the material to penetrate the ground, and repeat 2-3 times, then rinse the ground to remove excess material on the surface.

4. Ultra-fine polishing (mirror fruit): To improve the gloss and light fruit of the ground to reach the mirror fruit, a 1.1KW high-gloss polishing machine can be used, and 500-mesh, 1000-mesh, 2000-mesh, and 3000-mesh diamond polishing pads can be adhered to the disc. Watering ultra-fine polished floor.

Wear-resistant floor construction technology

1. Removal of scum: Slowly and evenly destroy scum on the surface of a single concrete with a machine equipped with a disc.

2. Spread material: Spread the specified amount of 2-3 wear-resistant material on the concrete surface in the initial setting stage. After the abrasion-resistant material absorbs moisture, the mechanical operation of adding a disc is performed, and when the abrasion-resistant material is hardened to a fixed stage, the abrasion-resistant material spreading operation is performed twice.

3. Disc operation: After the abrasion-resistant material absorbs moisture, perform mechanical operations for installing discs at least three times. The speed of the machine will be degraded depending on the hardening of the concrete. The mechanical concrete operation should be crisscrossed.

4. Finishing the surface: The final modification of the wear-resistant flooring material is processed using mechanical concrete or manual concrete. When polishing, it should be criss-crossed. The angle of the iron plate and the speed of the machinery should be adjusted and cut according to the hardening of the ground surface. .

Generally divided into ordinary resin grinding discs and super hard resin grinding wheels according to the grinding material. Ordinary resin grinding wheels are made of white corundum, brown corundum and silicon carbide. Super hard resin grinding wheel is a grinding wheel with diamond or CBN as the main grinding part.

In the production process, diamond wheels are used to polish the belt. Usually, the wheel is removed for cleaning after 5-7 days of operation.

Now we soak it in acetone for 2 hours and then clean it with imported cleaner. The effect is very good, but it is not environmentally friendly and does not save energy. The cleaning of resin polishing pads requires environmental protection and cannot damage the diamond wheel.

The concrete polishing pad adopts special formula and technology, which is specially used for the grinding, polishing and refurbishing treatment of industrial floors, warehouses, parking lots and other concrete floors, cement self-leveling floors, various aggregate hardener floors and liquid hardener floors.

1. Base surface treatment: fully soak the ground with water, use a high-pressure scrubber or a refurbisher with a hard brush to fully clean the loose surface layer, and treat the hollow drum part separately.

Precautions:

1. Select different types of refurbishers and polishing pads according to needs and experience. The grinding effect will be affected by various factors: ground hardness, grinder weight, counterweight, speed, whether water is added and the amount of water, polishing pad model, quantity, polishing Pad size, grinding time and experience, etc .;

2. Select polishing pads with different grain sizes according to the hardness of the ground and the experience of the technician. , 1000 #, 1500 #, 2000 #, 3000 #.

3. Dry and water mills use polishing pads with different formulas. Water mill can reduce dust on site and improve efficiency. The granularity number is: 30 #, 50 #, 150 #, 300 #, 500 #, 1000 #, 2000 #, 3000 #. It can be selected according to the actual situation. The effect and the hardness and flatness of the ground are used. , Grinding time, use experience. Throughout the processing process, rough grinding and fine grinding are more uniform and more thorough, and fine calendar and polishing can be saved in the heavy effect. Good grinding and polishing will save time and effect.

4. It is recommended to clean the ground before using the next size pad after each grinding, otherwise it will affect the grinding effect.

The polishing pad has a uniform and standardized particle color system and good flexibility. It is widely used in the processing of marble, artificial stone and other lines, countertop curved plates and special-shaped stone processing. There are multiple shapes to choose from, and different particle sizes are used differently. Colors can be distinguished and can be matched according to the different needs of customers. Then, only using polishing pads is not enough. The following aspects also need attention:

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

2. During work, the workpiece should be fixed, and the profile positioning should be in the direction of the cutter to avoid abnormal cut-in. No side pressure or curve cutting is applied. The knife is sent smoothly. Flying out and causing an accident.

When working, the fixed pressure is applied to the machine while the water is flowing. 4-5 times can be exchanged on the surface of the stone being polished. You can replace the finer abrasive discs. After understanding the aspects needing attention, you will use the polishing pad more flexibly and safely.

Stone refurbishment refers to repairing, grinding, and polishing the newly paved stone, or repairing, grinding, and polishing the old damaged stone to eliminate the height difference and maintain the stone’s brightness and flatness. It also renews its natural and luxurious nature.

Stone renovation is divided into marble renovation, terrazzo renovation, artificial renovation, granite renovation and so on. Different stone materials, the renovation process is also different, but the same. (For example, the overall density of marble is lower than that of granite, but the number of types is difficult to count. The density difference is not small, so the grinding time and materials used for refurbishment will also vary. Granite has a higher density. , So the renovation will take longer.)

Polishing-pad-size

First, the tools used in stone renovation are:

Stone refurbishing machine, single brush machine, hand throwing machine, angle grinder, stone slitting machine (cutting machine) and other tools and equipment.

Second, the materials used in stone renovation are:

Crystal powder, crystal hardener, diamond polishing pad, polishing pad, abrasive brush, marble adhesive, hot rubber, red pad, white pad, steel wool and other materials.

Third, the stone renovation process:

Spiral polishing pad

1. First clean up the original fillings between the stone gaps, and then use a special stone slitting machine to cut the slits of the original stone installation neatly to reduce the gap width between the stones to a minimum. The color is filled with marble adhesive.

2. Use marble glue close to the color of the stone and perfect color matching, so that it is close to the color of the original stone to improve the overall sense and achieve the best visual effect.

3. Fill the adjusted marble glue. Because the marble glue will shrink to a certain degree after it is completely solidified, the marble glue should be slightly higher than the stone level, so that it will not be filled multiple times.

4. Use polishing pads and fillers to make it a horizontal surface with the stone, increase the overall sense of the stone, and solve the problem of the height between the gaps to prevent the gaps from turning black again. The granite refurbishment machine is used together with the special cutting polishing pad to carefully polish the cutting position, so that it becomes a flat whole with the stone.

5. Grinding and polishing: Use a special stone rock polishing machine to grind from coarse, medium and fine sizes. If rough ground is found during the grinding process, the ground has pits, drops, crystals, and honey. After the watch is completely dry, it must be repaired separately. After the overall grinding, the ground flatness cannot be seen by waves, which makes the ground bright and flat as new.

6. Crystallization treatment: The stone crystal powder and crystal agent are used in combination with the crystal surface sander to polish. Under the weight of the grinding, the stone and the crystal powder undergo a comprehensive physical and chemical reaction under the action of high temperature to form a dense and hard crystalline protective layer. . After crystallization, it can enhance the color and brightness, and can also achieve anti-slip, waterproof and oil-proof effects.

The polishing pad has a uniform color system and good flexibility. It is widely used in the processing of granite, marble, artificial stone and other lines, chamfers, countertops, curved plates and special-shaped stones. Choose, each size number is distinguished by different colors. Nowadays, polishing pads are often used when polishing the surface of some materials such as metal, marble, and tile. Then what is the role of the polishing pad?

Machine or refurbished machine, DS grinding discs with different particle sizes are used for rough grinding, fine grinding and polishing.

Polishing pads are widely used in industrial equipment. Nowadays, polishing pads are often used when polishing the surface of some metals, marbles, ceramic tiles and other materials. The above is all about the role of polishing pads. I hope everyone will read them Will understand.

Marble-floor-polishing-pads

Floor paint construction often encounters the phenomenon that the newly installed polishing pad has been consumed too quickly before it has been used. So what is causing the polishing pad to run out too quickly?

The reason for the fast consumption of polishing pads

The polishing pad is divided into soft foundation, medium foundation and hard foundation. Hard foundation polishing pads are used for the ground with poor compactness. Soft foundation polishing pads are used for better quality. Generally, it is sufficient to use medium foundation for the ground. During the initial construction period, some concrete The quality of the ground is relatively poor, especially in the case of some old ground renovations. The flatness is poor, the ground is loose, and the water mill treatment is prone to generate a lot of mud, which causes the polishing pad to be consumed very quickly. The main reason for polishing pad consumption.

Solution

1. For the ground with poor quality, it is recommended that you use medium and large floor grinders, spray dry on the ground, and then use dry grinding. Select a hard-based metal polishing pad No. 30 and loosen the surface layer before leveling. Processing, then use a 100-type hard or soft base metal polishing pad and then process and polish, the basic hardness and flatness are not all processed, and the subsequent work is much simpler.

2. If you encounter sand with poor ground foundation density and the polishing pad will wear each other, so it is easy to accelerate the consumption of the polishing pad. At this time, we can first perform purification treatment to achieve higher ground density. Polishing later can save the use of polishing pads.

3. It is recommended to use diamond polishing pads or thick concrete polishing pads for ground leveling and rough grinding. Fine sand polishing pads can be used without coarse sand polishing pads.

4. It is recommended to use sharp resin polishing pads for hard concrete floors, increase machine counterweight, reduce mill speed, and reduce forward speed.

5. It is recommended to use durable resin polishing pads for soft concrete floors, increase the speed of the mill, and accelerate the forward speed.

6. When using the polishing pad, do not use jump numbers. According to the normal use situation, dry grinding is more consumable than water grinding, but water grinding treatment will make the ground more uniform and delicate.

From the above understanding, we know that in the early stage of the construction of wear-resistant floors, the quality of most concrete floors is not very good, especially for the refurbishment of some old floors, the flatness is not good, the ground is loose, and the hardness is poor. Mud, causing the polishing pad to be consumed particularly quickly. At this time we need to choose different polishing pads for different floors.

6-inch-diamond-polishing-pads

The most common stone grinding disc is the diamond polishing pad. The diamond polishing pad is mainly made of high-quality resin binder and diamond micro-powder, combined with advanced and exquisite technology. It is widely used in floor renovation, stone processing and In the production of ceramic tiles and other industries.

Because the diamond polishing pad has a relatively uniform color and color, whether it is chamfered on marble or granite, the processing on the lines is very wide, and the choice of specifications and shapes is more diverse, different. The granularity is differentiated by using different colors, and the devices can be used according to the needs and habits of the users.

After the diamond grinding disc is added with water, the conditions for its use will also be improved, and the grinding, polishing and processing of ceramics, glass and stone can be effectively processed. The sharpness and heat resistance of the spiral diamond grinding disc are better, and Under the premise of not changing the color of the stone itself, it has the characteristics of high brightness, fast glazing and no fading.

Stone polishing pad use

The first step is rough grinding. In rough grinding, we require the polishing pad to have a deep knife and high grinding efficiency. The grinding grain is thicker and the ground surface is rough. The main function is to clear the diamond. The saw blade marks left in the previous process and the flat surface of the stone is ground in place.

The second step of fine grinding, the finely ground diamond surface pattern, particles, color, etc. have been clearly shown, and the surface is more delicate, smooth, and the finely ground stone began to have a weak gloss.

In the third step, the polished and polished stone surface has no visible marks, and the surface will be smoother and smoother, and the highest degree of lightness can reach 55 degrees or more.

The fourth step of polishing, after we have done the first few steps, we use marble polishing machine to grind the marble from 50-3000 stone polishing pad from coarse to fine, which can make the ground bright and new as new The polished marble surface is very bright, and the marble’s lightness can reach 85 degrees or more.

Because the polishing pad has uniform and standardized grain color and good flexibility, it is widely used in stone processing, and has multiple shapes. Various grain sizes are distinguished by different colors, which can be matched according to different needs of customers. So what should you pay attention to when using the polishing pad?

Precautions for use

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

2. When working, the workpiece should be fixed, the profile positioning should be consistent 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 workpiece contact, resulting in saw blade damage, or workpiece Flying out, causing an accident.

3. When cutting and stopping cutting, do not use it 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 life of the saw blade and cut fruit; wet cutting, should be cut with water to prevent leakage.

The above is the use of stone polishing pads. The polishing pads are easier to process lines, chamfers, curved plates and shaped stones due to the complete and standard particle size color system and good flexibility. The specifications are optional, the various particle sizes are easy to distinguish, and the various grinders can be flexibly configured according to needs and customization. The various floors and steps laid on granite, marble and artificial stone slabs can be treated and refurbished according to needs and habits. Use a variety of hand or refurbished machines.

For the grinding and polishing of tiles, tile manufacturers have manufactured complete 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.

The reason why stone is loved by people, in addition to the charming natural color and hard texture, crystal clear luster is always the people’s favorite. People always pursue the high luster of stone, because the higher stone luster will show the nobleness and grandeur of the stone. However, the understanding and evaluation of the luster of the stone is relative.

The same kind of stone, grinding and polishing equipment and materials, the gloss is not the same; the same equipment and materials, will also get different luster in different stone varieties; in addition, the gloss of the stone and processing The environment and skills have a big relationship. Therefore, how to improve the polishing technology and effect of stone has been a subject of constant efforts in the industry.

The links and processes related to stone grinding and polishing can be divided into factory grinding and polishing and maintenance grinding, or large grinding and small grinding. Of course, due to some factors, some small equipment and tools are used in the factory to polish and polish the stone. We call it a small polishing.

For example, repair of broken sheets, processing of irregular shapes, processing of lines, and the like. Maintenance of grinding and polishing refers to reprocessing the stone gloss during the installation and application of the stone.

First, the significance of improving the gloss effect of stone reprocessing

In the different stages of stone application, there will be requirements for small polishing or re-polishing of the stone part or whole according to the needs. For example, in the case of grinding and polishing a small area of ​​stone, like in the case of repairing the board, the sheet is trimmed. In the case of the restoration of the surface gloss of the stone, as in the case of refurbishing the surface of the stone.

In these cases, the grinding and polishing of the stone is difficult to obtain a gloss which is consistent with or higher than that of the large plate or the original surface due to the restriction of equipment and materials.

Stone application is a systematic project, we emphasize the consistency of stone gloss.

Due to individual sheet or partial treatment, these individual local gloss drops can affect the coordination and consistency of the overall effect.

The overall grinding and refurbishment of the floor may also be less than the original effect. The marble countertops will also have the requirement to restore gloss due to local wear or acid corrosion. Although these conditions are a very small part of the overall application of stone, the effect will be very high attention, and these are also places that reflect details and meticulousness, and are also prone to disputes. Therefore, the restoration of the local luster of the stone and the improvement of the regrind and polishing are very important for the overall improvement of the effect of the stone.

Second, the current market situation of small grinding materials and technology

For the local grinding and polishing of stone, these small grinding and polishing processes, the existing equipment and materials are still relatively old, or extend the angle grinder, polishing pad and wax. It is difficult to obtain a good gloss effect by using these tools and materials, and the trace of luster is obvious, and the effect is not durable. These treated parts and parts tend to attract people’s attention and have a greater impact on the evaluation of effects.
As for the overall grinding and refurbishment of the stone floor, due to the increase in business volume in recent years, people have made great changes in equipment renewal and material investment. The refurbishment equipment has greatly improved in terms of power, gravity and speed. The matching grinding and polishing materials have also undergone major changes in types and performance, and are also more specialized and serialized.

For the gloss treatment of the profile and the line, although the existing equipment will give it a better luster, the seams and the like are still handled manually by people. Although there are some products such as hand-powder on the market, they are rarely used for reasons of efficiency and efficiency. So we still often see that wax is still a frequent choice for people under these conditions.

Third, stone polishing method

Polishing principle of stone products: The beauty of decorative stone, in addition to the color of the product, is mainly reflected in the gloss of the product, so the polishing of the product is an important and key link. How to polish the product to achieve the best effect, first of all, to understand the polishing Materials, methods, principles.

The polishing materials are mainly chromium oxide (Cr2O3), white corundum, alumina (Al2O3, 0.3um, VK-L30F), oxalic acid (COOH2).

There are two types of polishing stones: resin polishing blocks; resin polishing disks.

Polishing of the product: placing the polishing stone on the processed product, using the mechanical equipment to run quickly and dry polishing, wet polishing to achieve the polishing effect, the surface of the product will have a strong reflected light, which is commonly known as gloss .

The principle of polishing is mainly reflected in two aspects: the principle of particle grinding; the principle of physical chemistry.

1. Microparticle grinding: When the abrasive particles are coarsely ground to finely ground and polished, the traces of the abrasive on the surface of the stone are traced from coarse to fine to no visible to the naked eye, and the surface is smooth, smooth and delicate. When it reaches 110 microns, the surface of the processed surface has a specular gloss, which is radiant and bright.

Particle grinding consists of the following processes:

1 Rough grinding: requires the grinding tool to have a deep knife, high grinding efficiency, rough grinding, and rough surface. It mainly removes the traces of the saw blade left in the previous process and flatten the product. , the molding surface is ground in place;

2 semi-fine grinding: the coarse grinding marks are removed to form a new thinner grain, and the processing surface of the product is smooth and smooth;

3 fine grinding: the finely ground product pattern, granules and color have been clearly displayed, the surface is fine and smooth, and begins to have a weak gloss;

4 Fine grinding: After processing, there is no trace of the naked eye. The surface is getting smoother and the gloss is about 40~50 degrees;

5 Polishing: This step is the most important place for light extraction. Generally, it needs to be processed with alumina mirror polishing powder (VK-L30F) of about 0.3um. The surface of the treated stone is bright as a mirror and has a certain specular gloss. 85 degrees or more).

2, physical and chemical principles: polishing process has two, namely “dry and wet polishing”, polishing stone between “dry and wet” when the physical and chemical effects of stone products, dry polishing is the temperature of the stone surface Evaporation of water leads to an increase in the concentration of the polishing grindstone, thereby achieving a strengthening effect, and the gloss of the product begins to meet the desired requirements, and the gloss is above 85 degrees or higher.

The polishing stone is polished on the processed product. After the polished product is hot, add water to the surface to reduce the temperature. It is not allowed to add water or add a large amount of water. Otherwise, the lubrication of the water will make the polishing less than Ideally, dry polishing cannot be used all at all. Excessive temperatures can burn the surface and crack the surface.

Generally speaking, after the product is finely ground, the gloss of the product is about 40~50, and some stones can not reach the above gloss after fine grinding, such as Shanxi black, black gold sand, Jining black, etc. The gloss is only between 20 and 30 degrees. It is explained by the principle of particle grinding in the front. This product is dry and wet, the temperature rises, the temperature is lowered, the polishing process is strengthened, and the physical and chemical reaction occurs. After dry polishing and wet polishing, the gloss is gradually increased, and the gloss is more than 85 degrees.
