How many kinds of sandpaper are there?

In actual use, the classification of sandpaper is not uniform.

Sponge sandpaper

Suitable for grinding smooth parts, all kinds of materials are available.

The sponge sandpaper sanding process has the characteristics of high production efficiency, good surface quality, and low production cost. Therefore, it is widely used in furniture production. The final surface quality of furniture products is closely related to the sanding process. Sponge sandpaper is the main tool of the sanding process.

Dry abrasive paper

Dry abrasive paper uses synthetic resin as a binder to bond silicon carbide abrasive to latex, and is coated with an antistatic coating to make a high-end product. It has the advantages of anti-clogging, anti-static, good flexibility, and high wear resistance. . A variety of finenesses are available, suitable for polishing metal surfaces, putty and coating. Dry sanding paper is generally made of special kraft paper and latex paper, natural and synthetic resins are used as binders, and manufactured through advanced high-static sand planting technology. This product has high grinding efficiency and is not easy to stick to chips. It is suitable for dry grinding. . It is widely used in furniture, decoration and other industries, especially rough grinding.

Water matte paper

The texture is relatively fine, water matte paper is suitable for polishing some finer textures, and suitable for post-processing;

The gap between the sand grains of water abrasive paper is small, and the crushed powder is also small. When used with water, the crushed powder will flow out with the water, so use it with water. If you use water-based sandpaper for dry grinding, the crushed powder It will stay in the gaps between the sand grains and make the surface of the sandpaper lighten and thus fail to achieve its original effect. Dry sandpaper is not so troublesome. The gap between the sand grains is larger, and the grinding powder is also larger. It will fall off due to the large gap during the grinding process, so it does not need to be used with water.

According to product name:

Wood sandpaper, that is, dry sanding paper; water sandpaper, that is water-resistant sandpaper; iron emery cloth, a kind of dry sanding paper, is relatively coarse and can polish the metal surface as soon as possible.
