White corundum is made of high-quality industrial alumina powder as the main raw material. It is made in an electric arc furnace after being smelted at a high temperature above 2000°C and then cooled. It is broken, magnetically separated to iron, and sieved into various particle sizes. It has white color and high hardness. High purity, excellent self-sharpening, high efficiency, acid and alkali corrosion resistance, high temperature resistance, good thermal stability and other characteristics, it is the main raw material for the production of medium and high-end shaped and unshaped refractory materials, and is also widely used in the manufacture of ceramics and resin abrasives And sandblasting, grinding and polishing, precision casting, special ceramics and other industries.

It is white, slightly higher in hardness than brown corundum, and slightly lower in toughness. Abrasive tools made with it are suitable for grinding high carbon steel, high speed steel and quenched steel. It can be used as grinding and polishing materials, as well as precision casting molding sand, spraying materials, chemical catalyst carriers, special ceramics, advanced refractory materials, etc.

White corundum abrasive is suitable for beautifying the surface of various high-end products, craftsmanship or hardware products. The surface is white after sandblasting without any impurities, eliminating the trouble of cleaning. Fine white corundum can be used as the head of polishing. Can also be used as additives for various products. It can be used as solid and coated abrasives, wet or dry or blasted sand, suitable for crystal, super precision 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 harder materials with higher tensile strength. It can also be used as contact media, insulators and precision casting sand. Derusting, decontaminating and descaling of iron workpieces, increasing the adhesion of coatings and coatings; descaling of aluminum workpieces, surface strengthening and light decoration; matte effect of descaling of copper workpieces and crystal frosted glass products , Matte effect of carved plastic products, denim and other special fabric plush processing and effect patterns.

Application

1. Surface processing: metal oxide layer, black carbide skin, metal or non-metal surface rust removal, such as gravity die casting mold, oxide or release agent of rubber mold, black spots on ceramic surface, uranium color removal, painting Rebirth.

2. Landscaping: all kinds of gold, K gold jewelry, matt or matte surface treatment of precious metal products, crystal, glass, corrugated, acrylic and other non-metallic matte surface processing and can make the surface of the processed object into metallic luster.

3. Etching: jade, crystal, agate, semi-precious stones, seals, elegant stones, antiques, marble tombstones, ceramics, wood, bamboo, etc.

4. Pre-treatment processing: Teflon (TEFLON), PU, rubber, plastic coating, rubber drum (ROLLER), electroplating, metal spray welding, titanium plating and other pre-treatment to increase the surface adhesion.

5. Flash processing: remove the flash of bakelite, plastic, zinc, aluminum die-casting products, electronic parts, magnetic core, etc.

6. Stress relief processing: stress relief processing for parts of aerospace, national defense, precision industry, derusting, paint delustering, renovation, etc.
