In terms of stone, how to understand its abrasiveness and other properties, and what are the differe

The abrasiveness of stone is its hardness, and how to polish it?

If you don't test, as long as you look at it with your eyes, I can talk to you about ,-- eyes, that is, there is no fine pores of stone, the sound is relatively crisp, and the water is not easy to soak into, that is, the density of the stone is relatively high, and the hardness is relatively high, so its hardness is relatively high and the luminosity will be higher, that is, the material is better.

-Abrasiveness means that the harder the stone, the more difficult it is to grind, and it can't be grinded, but it has a high luminosity.

-The abrasiveness of stone is generally divided into three types, 1>> hardness is relatively high, such as granite--- Indian red, South African red and the like.

2>> medium hardness, for example, Kadoory, British brown, red diamond, 3>> very low hardness is the material is relatively soft, such as black gold sand, Mongolian black, Shanxi black, in fact, there is another kind, rarely encountered, medium hardness, is a little sticky. It feels like rubber, it's neither hard nor soft, but it's hard to grind, but it's easy to open it.

- The above is to say the abrasiveness of the stone, according to the material and hardness, not the quality of the stone.

Enter the China Stone Network to take a look, there are many professionals in this area, and the introduction is very detailed.

Different colors and different resistances, you can know by burning them with fire.

Stone grinding requires several characteristics, one is hardness, one is toughness, and the other is abrasiveness. If the hardness is not enough, it is easy to disintegrate, if the toughness is not enough, it is easy to break, and if the abrasiveness is not enough, it is not resistant to wear.

To summarize the above points. The best stone for stone grinding is currently recognized as bluestone and granite, which is the best white hemp, hard enough, tough enough, and the degree of wear resistance is the highest in the current stone grinding market.

Stone characteristics and advantages of white hemp:

1. No deformation, high hardness and strong wear resistance.

2. Anti-abrasion, high temperature resistance, maintenance-free.

3. The physics is stable, the structure is meticulous, the impact grains fall off, the surface is not burr, it does not affect its plane accuracy, the material is stable, and it can ensure that it is not deformed for a long time.

The linear expansion coefficient is small, the mechanical precision is high, and it is anti-rust, anti-magnetic and insulation.

4. Fujian white hemp has excellent quality, high surface finish, corrosion resistance, acid and alkali resistance, high hardness and density, high iron content, and non-radioactivity, which is equivalent to that of American white hemp.

The traditional stone grinding is best made of large bluestone stone, which is of the best quality, natural and healthy and hard.

Granite can be this one with no counterfeit ingredients.

It's hard to tell if you're not a professional!

Summary. Although the material and craftsmanship of the grinding stone vary depending on the region and use, the best grinding stone should be made from natural minerals with high hardness, such as quartz, sandstone, granite, etc. These minerals have high wear resistance and durability, and are able to maintain the shape and surface quality of the grinding stone for a long time.

When making a grinding stone, you first need to choose the right minerals, and then process and polish them. Normally, the process of making a grinding stone includes the following steps:1

Choose the right minerals and cut them into the right size and shape. 2.The minerals are sanded with a hammer and chisel into the basic shape of the grinding stone.

3.Use tools such as a grinding wheel and sandpaper to sand the surface of the grinding stone until smooth. 4.

Finally, the grinding stone is polished and painted to improve its surface gloss and durability. In conclusion, the best grinding stones should be made from natural minerals of high hardness and finely machined and sanded. The result is a grinding stone that not only has high wear resistance and durability, but also provides better grinding results and is suitable for a wide range of grinding tasks.

What is the best process material for exterior wall grinding stone?

The best process material for exterior wall grinding stone should be terrazzo material. Terrazzo is a material mixed with natural stone and cement, which has good weather resistance, wear resistance, water resistance and anti-fouling properties. In addition, terrazzo also has a high degree of decoration and can be customized according to different design needs, making the effect of exterior wall grinding stone more beautiful.

In contrast, other common exterior wall grinding stone materials such as marble, granite, etc., although the pants also have good durability and decoration, but they are higher and not suitable for large-scale use. Terrazzo, on the other hand, is relatively affordable and has a wider range of applications. In short, the use of terrazzo as the material of the exterior wall grinding stone can not only ensure the beauty of the appearance of the building and the durability of the erection, but also save costs, which is a very good choice.

Grinding stone generally refers to various abrasives used in vibration (grinding) polishing machines, rolling (grinding) polishing machines, and can also be used in centrifugal (grinding) polishing machines, vortex (grinding) polishing machines and other (grinding) polishing machines.

Grinding spike grinding stone refers to all kinds of abrasives used in vibration (grinding) polishing machine Li Heng, rolling (grinding) polishing machine, and can also be used in centrifugal (grinding) polishing machine, vortex type which group does (grinding) polishing machine and other (grinding) polishing machines.

Stone polishing its meaning is:

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 role and characteristics of stone polishing are:

The consistency of grinding is good, and the lines of different sizes can be installed in a disordered order, which has good interchangeability;

The polished lines have no waves, and the flatness and straightness of the surface are very good;

The products used for grinding rotary bodies have good arc and high luminosity; High efficiency;

Reduce the labor intensity of grinding and polishing operations;

Improve the working environment for grinding and polishing;

Suitable for assembly line production;
