In the abrasive industry, the use of white fused alumina micro-powder is very common, with high purity, good self-sharpness, acid and alkali corrosion resistance, high-temperature resistance, stable thermal performance, etc., suitable for all kinds of sandblasting and polishing. The form of assignments is explained below in detail:
White fused alumina fine powder can be used as a solid structure and coated abrasives, wet or dry blasting sand, suitable for super-precision grinding and polishing in the crystal and electronics industries, and making advanced refractory materials. It is suitable for processing hardened steel, alloy steel, high-speed steel, high carbon steel, and other harder materials with higher tensile strength. White fused alumina powder is harder and more brittle than brown corundum, and the cutting force is stronger. It has good chemical stability and good insulation.
The white fused alumina fine powder grade is very suitable for wet sandblasting and polishing operations; it does not affect the color of the processed parts; it can be used for sandblasting in the process where the iron powder residue is strictly prohibited; the processing speed is fast and the quality is high; the amount of iron oxide contained is extremely low. Sandblasting of iron residues.
White fused alumina is made of industrial alumina powder, smelted in an arc at a high temperature of more than 2000 degrees, and then cooled. It is crushed and shaped, de-ironed by magnetic separation, and sieved into a variety of particle sizes. Its texture is dense, high hardness, and the particles form sharp angles. The shape, White fused alumina is suitable for manufacturing ceramics, resin-consolidated abrasives, grinding, polishing, sandblasting, precision casting (corundum for precision casting), etc., and can also be used to manufacture advanced refractory materials, code-named “WA” in international general standards, countries The standards are the same, most are for export, and a certain amount is also supplied to domestic users. Aluminum oxide (Al2O3) content is above 98%, and contains a small amount of iron oxide, silicon oxide, and other components, showing white. White fused alumina is white, slightly harder than brown corundum, and slightly tougher. Abrasives made of White fused alumina are suitable for grinding high carbon steel, high-speed steel, and hardened steel. It can be used as an abrasive polishing brush. White fused alumina can also be used as precision casting sand, spraying material, chemical catalyst carrier, special ceramics, advanced refractory materials, etc.
White fused alumina powder is used in the following aspects:
1. It can be used in various sandblasting and lapping operations;
2. Atomized aesthetic processing of Poly or acrylic arts;
3. Sandblasting is the process of TV screen;
4. Cutting of silicon wafers;
5. Cleaning and sandblasting of the tooth mold;
6. Molding sand for precision casting;
7. Advanced refractory materials and other ceramic additives;
