How to choose a concrete polishing pad?

The whole process of concrete polishing pad can be divided into four stages: rough grinding, fine grinding, fine grinding and polishing. The processed stone has a gloss of more than 90°.

Since the construction site does not allow ash to be lifted, it can only be operated with water. Therefore, the water mill construction is beneficial to heat dissipation and lubrication scouring, which can extend the life of the mill and make the ground more uniform and delicate. Then, how to choose a concrete polishing pad?

1, The flatness of the ground:

Manually leveling the ground or loosening, seriously damaging the old ground, need to level or remove the loose surface, need to use a high-power grinder, use a concrete diamond grinding disc and other polishing machine, suitable for flat grinding.

Cement self-leveling grinders or polishing machines should find a better level of ground flatness. Only diamond resin grinding can make the polishing more beautiful and the grinding parts are more economical.

2, the hardness of the ground:

Concrete used in the design and construction of concrete floors is indicated by a label number, namely C20, C25, C30, etc. Under normal conditions, the higher the label, the better the strength and hardness of the concrete. However, due to various factors, the hardness of the concrete and the hardness of the ground often do not correspond.

The hardness of concrete floors is usually expressed in terms of molar hardness. The hardness of concrete slabs is usually between 3-5. At the site, we can use some alternative Morse hardness testers to understand the hardness of the ground: the hardness of the dent can be marked with nails and keys, otherwise the hardness is greater than 5.

3, the weight and speed of the grinder:

Grinders are usually divided into small, medium and large. In general, the larger the machine, the greater the power and the higher the efficiency; in actual use, the larger the machine, the higher the efficiency. Although the grinding efficiency is high, excessive grinding often leads to excessive grinding in use, which increases construction costs. According to the characteristics of the machine, experienced workers can adjust the speed, moving speed, the number and weight of the grinding machine, reduce construction costs and improve construction efficiency.

Finally, the hard flattening effect is better, and it is more suitable for medium and large grinding machines. The soft grinding disc has better polishing effect and is suitable for various grinding machines. It is recommended to use diamond grinding discs and thick grinding discs for leveling and rough grinding. Fine grinding discs are recommended for finishing and polishing.

Marble polishing pad instructions

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 explain and describe in detail how to use and use the polishing pad from each step used in the marble polishing pad.

Marble polishing pad use

1. Thoroughly clean the ground. Use the knives to remove the concrete slurry from the stone gap and then thoroughly remove the dust with a brush, vacuum cleaner, etc. 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. Firstly, the original damaged surface is repaired with marble glue close to the stone color. Then use a special stone slitting machine to re-align the slits of the original stone installation to make the width of the gap uniform, 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. Finish the first time of polishing, re-cast the marble glue, insert the seam, complete the second grinding, then use the stone refurbished machine with the steel stone grinding disc from coarse to fine, a total of seven grinding and polishing is required. The whole surface is flat and 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. Grind it with a marble polishing machine. 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. Make the crystal surface material crystal on the surface of the stone. The surface effect formed after the formation.

6, the overall ground maintenance treatment: If the stone with a large gap is to be treated with a marble protective agent, re-grinding once to increase the hardness of the crystal surface of the entire ground.

7. Ground cleaning and maintenance: When the surface of the stone is crystallized, use a vacuum cleaner to absorb the residue and moisture on the ground. Finally, polish the surface with a polishing pad to make the whole surface completely dry. Bright as a mirror. If local damage is possible, local maintenance is possible. Construction can be done at any time.

Steps to renovate the floor refurbishment

Stone refurbishment is part of stone maintenance and consists of three steps: rough grinding, fine grinding and polishing. The steps of renovating the floor refurbishment floor, each step is carried out with the use of diamond abrasives.

1. Rough grinding will remove scratches, corrosion, and traffic marks on the surface.

2, fine grinding, smoothing the ground and grinding the surface.

3. Polished, diamond abrasive will polish the surface. The water is constantly flowing as a lubricant for diamond.

The specific operation details have the following parts:

1. Base treatment:

(1) The large terrazzo machine is equipped with a coarse diamond grinding head water mill to smooth the ground and completely remove the epoxy resin coating.

(2) The large terrazzo machine is equipped with a fine grinding head water mill to ensure a smoother and smoother surface.

(3) Wash and remove clear water, and dry naturally for 3-7 days.

2, cement floor sanding agent A component construction

(1) Dilute component A with appropriate amount of water on the ground according to the ground conditions. The amount of raw liquid: 0.2-0.5kg/m2.

(2) When the surface has no clear water or becomes viscous, spray a small amount of water in time to keep the surface moist to promote penetration. The above operation lasts for about 4 hours. Finally, rinse the surface with enough water to remove the surface water and dry naturally. More than an hour;

(3) If the ground strength is poor, repeat the above steps after 24 hours.

Marble polishing renovation method

Grinding and polishing of marble grinding blocks is the first process of stone care crystal surface treatment. The weathering resistance is poor, so the worn surface is easy to lose luster. The marble can be refurbished according to the degree of wear on the marble surface, with a mild, medium and deep marble grinding and refurbishing method. Here’s how to polish the marble renovation process.

1. Thoroughly clean the ground, remove the concrete slurry at the gap of the stone with a knife, and then thoroughly remove the dust with a brush, vacuum cleaner, etc. Clean with a dry and clean ground, no sand or impurities on the ground.

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. Firstly, the original damaged surface is repaired with marble glue close to the stone color. Then use a special stone slitting machine to re-align the slits of the original stone installation to make the width of the gap uniform, 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. Finish the first polishing, re-cast the marble glue caulking, continue the second grinding with the caulking, and then use the stone refurbished machine with the water refining sheet from coarse to fine. A total of seven grinding and polishing is required. It is smooth and smooth, and then polished with steel wool. The polishing degree reaches the brightness required by the design, and there is no obvious gap between the stones. (Granite refurbishment must use bridge mills and professional grinding discs. Resin grinding discs should not be used. Rough grinding: Do not reduce the number of grinding passes and change the number of grinding discs. 60-mesh grinding discs are used to polish the stone floor, the height difference, The color of the glue such as scratches and deformations is basically the same, and must be full. Fine grinding: Do not reduce the number of grinding passes and change the number of grinding pieces.)

4. After the polishing 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 it, use a washing machine with a red scouring pad, spray the syrup with the same amount of water on the ground, start grinding, and heat the crystal surface material on the surface of the stone. The surface effect formed after the formation.

6, the overall ground maintenance treatment: If it is a large void stone to be marble protective agent painting, re-polishing once, in order 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 surface, use the vacuum cleaner to absorb the residue and moisture on the ground. Finally, use the polishing pad to polish, so that the whole ground is completely dry and bright as a mirror. If partial damage can be used for local maintenance, Construction can be done at any time. (After the surface of the stone is dried, it is hardened by crystallization until the surface effect required by the sample is achieved. The refractory travertine surface reaches a mirror gloss of 60 degrees or more, and there must be no height difference between the stones, and the granite surface is achieved. Above 80 degrees, there must be no leakage.)

How to choose the cutting blade?

Many of the peers who do stone care, when choosing the initial grinding sheet, are often selected according to the height of the ground cut. When we conduct on-site inspection, we find that the height of the panel is mostly above 3MM. The 30-mesh grinding disc will be selected for the trimming and smoothing treatment. If the height between the stone plates is below 3mm, then we generally choose 50 mesh for processing.

But is this really reasonable and correct? From the perspective of professional specifications, we choose the starting grinding sheet. The high and low cutting between the stone plates is an important basis for our choice, but it is not the only basis. We also need to refer to the physical properties of the stone to determine. The physical and chemical properties of stone include: bulk density, water absorption, Shore hardness, compressive strength, and the Shore hardness of these four items is directly related to our choice of grinding disc. The Shore hardness of stone is a special name for reflecting the hardness of stone. It is the data obtained by the authoritative organization through experimental testing. The higher the data, the higher the hardness of the stone. It is more difficult to grind directly on the grinding. The grinding needs to be more rounded. It is necessary to choose a sharper grinding piece (the smaller the grinding piece, the sharper it is). The smaller the Shore hardness data, the lower the hardness of the stone and the easier it is to grind.

After understanding the physical and chemical properties of the stone, we know that the selection of the grinding sheet should not only be based on the height of the stone, but also the hardness of the stone. The height of the floor is very large, but the hardness of the stone is very low. The original grinding piece does not need 30-mesh or 50-mesh grinding pieces. We can directly select 150 mesh or even 300 mesh. For example, when encountering white sand beige stone (its Shore hardness is 33), no matter how high or low the cut is, we can start grinding with 300 mesh. For stone like American white hemp, its height is not big, but we usually choose to start from 30 mesh because its Shore hardness is 109. After understanding these, the following is a comprehensive consideration when selecting the grinding disc according to the unevenness of the ground and the Shore hardness. This not only improves the efficiency of the work, but also reduces the material cost.

We must pay attention to a problem when choosing a cut-off grinding piece, that is, the grinding piece should be targeted and professional. What is the reason for this? In fact, grinding marble should choose marble professional grinding discs. Grinding granite series stone should choose granite professional grinding disc. Grinding and polishing brick series should choose polishing disc special grinding disc. If marble grinding is used to grind granite, we know that the cutting is flattened too slowly, the efficiency is low, and the labor cost is increased. When the granite is used to grind the marble, the speed of the smoothing of the cut will be increased, but the grinding loss will be fast and the material cost will be greatly increased. The special grinding discs of marble or granite are used to grind the polished brick floor, which may not be ground. The grinding sheet will slip, that is, it will be ground up, and the scratches of the grinding sheet will not be eliminated. Give us the subsequent process belt. Come a big problem.
