White corundum is a kind of artificial abrasive. The content of aluminum oxide (Al2O3) is 99% or more, and contains a small amount of components such as iron oxide and silicon oxide, and is white.
The product size is produced according to international standards and national standards, and can be processed according to the user's required particle size. The general particle size number is F4~F220, and its chemical composition varies depending on the particle size. The outstanding feature is that the crystal size is small and impact resistant. If it is broken by the self-grinding machine, the particles are mostly spherical particles, the surface is dry and easy to combine with the binder.
White corundum is made of industrial alumina powder. The particle size of white corundum is cooled by smelting at a temperature of over 2000 °C in an electric arc. After crushing and shaping, magnetic separation is carried out, and the sieve is divided into various particle sizes. The texture is dense and high in hardness. It is formed into a sharp angle and is suitable for the manufacture of ceramics, resin-bonded abrasives, as well as grinding, polishing, sandblasting, precision casting (special corundum for precision casting), etc. It can also be used to manufacture advanced refractory materials, codenamed "WA".
Scope of application: White corundum abrasive is suitable for the surface beautification of various high-end products, crafts or hardware products. After blasting, the surface is white and free of any impurities, eliminating the need for cleaning troubles. Fine white corundum can be used as the first polishing polishing. Can also be used as a variety of product additives. It can be used as a solid and coated abrasive, wet or dry or spray sand, suitable for crystal, ultra-fine grinding and polishing in the electronics industry and making advanced refractory materials. It is suitable for processing hardened steel, alloy steel, high speed steel, high carbon steel and other materials with hard hardness and high tensile strength. It can also be used as a touch medium, insulator and precision foundry sand. Iron workpiece derusting, decontamination, descaling, increasing coating and coating adhesion; aluminum workpiece descaling, surface strengthening, glazing; copper workpiece descaling matt effect, glass crystal scrub , patterned plastic products matt effect, denim and other special fabric plush processing and effect pattern
Scope of application:
1. Surface processing: metal oxide layer, carbide black skin, metal or non-metal surface rust removal, such as gravity die casting mold, rubber mold oxide or release agent removal, ceramic surface black spots, uranium color removal, painting Rebirth.
2, beautification processing: all kinds of gold, K gold jewelry, matte or matte treatment of precious metal products, crystal, glass, corrugated, acrylic and other non-metal matte processing and can make the surface of the workpiece into a metallic luster.
