What should be paid attention to in stone polishing, and the materials needed for marble polishing a

1.Personal protection is the most important (gloves, goggles, dust masks) 2See whether dry throwing or water throwing is required (with different tools, throwing pieces) 3

Look at the nature of the plate to be thrown (marble and granite hardness are different, the grinding techniques are also different, but also to prevent some plates from fading) 4If the corners are dropped in the edging, the broken stone should be bonded first and then polished. 5.

Good ventilation. (Poor ventilation and dust are easy to contaminate the board surface and glue, and the grinding edge of such a board surface is easy to blacken.) 6.

The water flow must be controlled to prevent the water flow from being poured to the edge of the grinding, causing the temperature of the board surface to rise and change color. 7.To prepare the corresponding color of marble glue (repair, bonding) 8

The fading stone should also prepare the corresponding color dye, and then color it after grinding. 9.After polishing, it should be polished with wool felt wax (according to the plate with the corresponding color of liquid wax, solid wax) 10

The ground finished plate should be placed according to the properties of different plates. That's too much to say first.

Wear a dust mask to protect your health.

Stone grinding and processing belongs to a high dust environment, in this environment to protect the delicate dust must wear a qualified dust mask, it is recommended to use the national standard KN100 dust mask for protection.

Dust masks belong to special labor protection equipment in China, and the national standard GB2626-2019 "Self-priming Filtering Anti-particulate Respirator" must be implemented, which divides dust masks into three levels: KN100, KN95 and KN90. For example, Baoshunan's 3216 KN100 and 3219 KN100 dust masks can achieve more protection efficiency against ultra-fine dust above microns.

The scientific selection of dust masks certified by the GB2626-2019 standard can help prevent lung damage.

1) Choose a compound half-mask type: disposable masks are not suitable for long-term or occupational protection due to their high air leakage rate;

2) Choose KN100 level: high dust environment and low protection rate will lead to physical injury;

3) Choose a silicone mask, which has a relatively long service life, is soft and comfortable. Wear it for a long time, it is not easy to cause allergic reactions; Masks with high hardness are easy to cause facial indentation;

4) It is extremely important that masks come in large and small sizes. It is not recommended to buy those so-called universal models of masks, different people are tall, short, fat and thin, and have different face shapes.

5) There are two types of masks: covering the mouth and nose, covering the mouth, nose and chin, and it is recommended to use the latter, which is relatively comfortable;

6) It is recommended to choose a breathless mask: especially a dust mask with a double filter + double filter surface design, which has a longer service life and is relatively smoother to breathe.

<><1. What materials are needed for marble polishing and grinding?

Marble polishing requires tools such as hand polishing machines, steel wool, 3M polishing pads, dust pushers and crystallization powders, and dry cloths. And during sanding, you can open the window or fan to speed up the drying of the floor, stir the floor wax evenly, and evenly apply it to the marble surface and band. After the wax surface is completely dry, use a polishing machine to polish the wax surface.

Second, marble polishing precautions

1. When grinding and polishing, the grinding and polishing of the smooth surface should be carefully checked after grinding each abrasive or grinding disc, and the traces of the previous abrasive should be covered after the next grinding.

2. When grinding and polishing, we should also pay more attention to the control of water volume, if its water volume is insufficient, it is easy to cause smooth surface burning.

3. When grinding and polishing, marble must be elongated as much as possible along the direction of the line element, and the longer the better, so as to directly avoid the phenomenon of ripples.

4. The speed must be fast when polishing, and then it will be better to process a large number of lines for grinding and polishing, which can directly reduce the workload of coarse grinding, and can ensure the consistency of the shape of the lines after grinding coarsely, so it is recommended that the grinding must be carried out according to the actual situation, if you will not be able to do so, you must ask a professional master to operate, not only polishing and polishing beautifully but also will not damage the material.

First of all, when the basic grinding is carried out, that is, the shear grinding is usually carried out as a whole, rather than grinding along the seam, which is the most important thing in the grinding process.

Secondly, grinding should have a quantitative concept, 50 mesh grinding needs several times to grind the ground flat, 150 mesh grinding several times to eliminate the 50 mesh wear marks, and so on, can not be taken for granted (skip number), otherwise scratches will be left after grinding, because the phenomenon of rework in this case is very common.

It is very important to choose grinding discs when grinding, especially the selection of starting grinding discs, many of our stone caregivers will generally choose according to the on-site stone height and low cutting situation, which is not comprehensive, not only to pay attention to the height difference of the ground, but also to choose according to the physical and chemical properties such as the hardness of the stone.

Check whether the shape of the product conforms to the shape of the production process processing sheet, and can enter the grinding and polishing process only after it is qualified;

Before grinding and polishing, the glue repair treatment is carried out according to the condition of the material, and the glue repair treatment is completed and then polished;

First, a single piece of line drawing is coarsely grinded, and the fine grinding and water grinding allowance left during rough grinding;

Splicing: The lines to be polished are spliced according to the installation drawing, and selected and adjusted according to the color of the surface of the lines to ensure a good effect of color and pattern. After the line water mill 500, the uniform number is first unified according to the requirements of the installation drawing, and then disassembled and polished, so that the polished and polished lines will not be concave and convex at the interface;

When there is dislocation at the interface, the grinding of the transition section should stretch the distance, the longer the better, and check the straightness with a ruler during grinding;

The lines that have been polished and polished can only be shipped after passing the quality inspection;

Special-shaped handicrafts grinding and polishing to improve luminosity and reduce waves

Choose a good grinding and polishing material;

When grinding and polishing, each abrasive or grinding disc should be carefully checked after polishing and polishing, and the traces of the previous abrasive should be covered up after the latter grinding number;

Attention should be paid to the control of water volume when grinding and polishing, as insufficient water volume is easy to cause smooth surface burning;

When grinding and polishing, try to elongate as much as possible along the direction of the line element, the longer the better, so as to avoid the generation of ripples;

Be fast when polishing;

Adopt high-speed grinding and polishing power tools;

It is best to use a forming knife to process a large number of line grinding and polishing, which can reduce the workload of coarse grinding and ensure the consistency of the shape of the line after coarse grinding.

The beauty of the 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 a very important and critical link, how to polish the product to achieve the best effect, first of all, we must understand the material, method and principle of polishing.

The polishing materials are mainly chromium oxide (Cr2O3), white corundum (alumina (Al2O3), oxalic acid (Cooh2).

There are generally two types of polishing grinding stones: resin polishing blocks; Resin polishing discs.

Polishing of the product: The polishing grinding stone is placed on the processed product, and the polishing effect is achieved by using mechanical equipment to run quickly and "dry polishing and wet polishing", and there will be a strong reflected light on the surface of the product, which is commonly referred to as gloss.

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

Many of our stone care people have such feelings, stone recrystallization hardening treatment is stone polishing is the most difficult to master in the stone care process, but also difficult to quantify the operation of a process, in the training of workers to spend the most time on a process, with the project on the volume of care stone is getting larger and larger, how to do a better and better polishing, this is a problem we must face.

Although stone polishing is difficult to master, it is not irregular, so how to play with polishing, we will share with you many years of experience, I hope it will help you in your work.

First, if you want to do a good job of polishing easily, first of all, we must understand: the premise of doing a good job of polishing is to do a good job of grinding, just like embroidering beautiful flowers on brocade. Doing a good job of grinding does not require you to grind to 6,000 or 10,000 mesh, but to do a good job of basic grinding.

Second, to do a good job in the later stage of polishing, the early renovation must do a good job of waterproof treatment, the basic conditions for polishing are: clean, dry, a certain brightness of the board surface. The degree of dryness in these three conditions is the most direct factor affecting the polishing effect, how to keep the stone dry is to do a good job of waterproof treatment before grinding.

3. Understand the physical and chemical properties and lithology of stone, and choose a good polishing agent. To do a good job in stone polishing, we must first choose the material suitable for the work object, how to choose, then we must understand the physical properties of the stone and the chemical composition of the stone, in the face of the company and the dazzling array of products on the market, there will be no way to start, and there will be no waste of manpower and material resources.

Fourth, understand the use of various media of stone polishing materials: stone crystal hard agent has block, powder, slurry, agent, paste five kinds of media, we must understand the characteristics and advantages and disadvantages of each medium, in the specific stone care work to do a good job, in order to different physical and chemical properties of stone, to make the same good effect.

Fifth, master the essentials of stone polishing: multi-media use, multi-variety superposition, multi-times polishing, quantitative change is the foundation, qualitative change is the result.

With these in mind, you'll be able to play with stone polishing with ease.
