W63 white corundum 280 mesh white corundum micropowder

Properties of white corundum

The color is white, and the hardness is slightly higher than that of brown corundum,High purity,Good self-sharpening, strong grinding ability,Low calorific value,High efficiency,Acid and alkali corrosion resistance,High temperature resistance, good thermal stability. Suitable for precision casting, refractory materials, grinding, sandblasting, polishing materials, spraying materials, chemical catalyst carriers, special ceramics, etc.

The production process of white corundum

White corundum is made of high-quality aluminum oxide powder as the main raw material, which is smelted at high temperature in an electric arc furnace.

White corundum powder is made of high-quality aluminum oxide powder as the main raw material, smelted at high temperature in the electric arc furnace to form white corundum blocks, crushed to small pieces by jaw crusher, ball mill for secondary crushing to make the particles smaller, and then through pickling to remove impurities, siphon segmentation, stirring and precipitation on time to extract different models, and then through precipitation drying and sieving loose.

Uses of white corundum

1Surface 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, painted rebirth.

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

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

4, pretreatment processing: Teflon (TEFLON），PU, rubber, plastic covering, rubber roller barrel (ROLLER), electroplating, metal spray welding, titanium plating, etc. before treatment, so that the surface adhesion increases.

5Burr processing: bakelite, plastic, zinc, aluminum die-casting, electronic parts, magnetic core, etc.

6Stress relief processing: aerospace, national defense, precision industry parts, rust removal, paint removal, matting, refurbishment, etc。
