A type of artificial abrasive. The aluminum oxide (Al2O3) content is more than 99%, and contains a small amount of iron oxide, silicon oxide and other components, and is white. The product particle size is produced in accordance with international standards and national standards, and can be processed according to user requirements. The general particle size numbers are 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 processed and broken by an autogenous grinder, the particles will be mostly spherical particles with a clean surface and easy to combine with the binder. White corundum is made of industrial alumina powder as raw material. Picture of the particle size difference of white corundum? It is made by smelting in an electric arc at a high temperature of more than 2000 degrees and then cooling. It is crushed and shaped, magnetically separated to remove iron, and screened into various particle sizes. Its texture is dense and hard. High, the grains form sharp angles, and are suitable for manufacturing ceramics, resin-bonded abrasive tools, grinding, polishing, sandblasting, precision casting (special corundum for precision casting), etc., and can also be used to manufacture advanced refractory materials, code-named "WA" in the international The general standards and national standards are consistent. Most of them are for export, and a certain amount is also supplied to domestic users. There are two types of density, one is packing density and the other is true density. Scope of application: White corundum abrasive is suitable for surface beautification of various high-end products, crafts or hardware products. After sandblasting, the surface will be white without any impurities, eliminating the trouble of cleaning.

Fine white corundum can be used as a polishing and grinding tool. It can also be used as a variety of product additives. It can be used as solid and coated abrasives, wet or dry or spray sand, suitable for ultra-precision grinding and polishing in the crystal and electronic industries and the production of advanced refractory materials. Suitable for processing quenched 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 contact media, insulator and precision casting sand. Remove rust, dirt, and scale from iron workpieces to increase coating and coating adhesion; remove scale from aluminum workpieces for surface strengthening and light decoration; remove scale from copper workpieces to achieve a matte effect and crystal frosting for glass products , engraved pattern plastic products with matte effect, plush processing and effect patterns on special fabrics such as denim.
