Metallographic sandpaper is specially used for rough grinding and fine grinding during metallographic sample preparation. Using selected silicon carbide abrasive grains with uniform particle size and excellent grinding effect as abrasives, the metallographic special water-resistant sandpaper is manufactured by the electrostatic sand planting process. It has the characteristics of uniform distribution of abrasive particles, sharp grinding and durability. As a result, the sample has a fast grinding speed and a shallow deformation layer, which is particularly effective for hard or hard materials. All rough grinding and fine grinding processes can be water-grinded, which completely eliminates the defects of the sample being ground and dusty when using ordinary metallographic sandpaper.
Classification of metallographic sandpaper:
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, and 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 sanding 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 abrasion 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, and the water matte paper is suitable for polishing some finer textures, and it is suitable for post-processing.
Water abrasive paper has a small gap between the sand grains, and the crushed powder is also small. When used with water, the crushed powder will flow out with water, so use it with water. If you use water-based sandpaper to dry ground, the crushed powder will flow out. 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. The 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.
