White corundum use
White corundum is made of high-quality aluminum oxide powder as raw material, refined and crystallized by electric melting. It has slightly higher hardness than brown corundum, lower toughness, high purity, good self-sharpening, strong grinding ability, low heat generation, and high efficiency. Acid and alkali corrosion resistance, high temperature resistance and good thermal stability. The abrasive tools made of it are suitable for grinding high-speed steel, high-carbon steel, etc., which are widely used in the industries of fixed abrasive tools, coated abrasive tools, polishing and precision casting. And because the white corundum is refined and crystallized by electric melting, the hardness is slightly higher than that of the brown corundum, the toughness is slightly lower, the purity is high, the acid and alkali corrosion resistance, high temperature resistance and thermal stability are good, and it is a kind of advanced refractory material.

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 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 processed and broken by a self-mill, the particles are mostly spherical particles, and the surface is dry and clean, and it is easy to bond with the binder.
1. Does not affect the color of processed parts;

2. It can be used for sandblasting in a process where iron powder residue is strictly prohibited;

3. The micropowder grade is very suitable for wet sandblasting and polishing operations;

4. Fast processing speed and high quality;

5. The amount of iron oxide contained is extremely low, suitable for sandblasting operations where iron residues are strictly prohibited;

6. After pickling step to remove impurities.
White corundum is suitable for surface beautification of various high-end products, crafts or hardware. After sandblasting, the surface is white without any impurities, eliminating the trouble of cleaning. Fine white corundum can be used as the first for polishing and grinding. It can also be used as a variety of product additives.

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, painted painting Rebirth.

2. Beautification processing: matte or matte processing of various gold, K gold jewelry, precious metal products, non-metal matte processing of crystal, glass, corrugated, acrylic, etc., and can make the surface of processed objects become metallic luster.

3. Etching processing: etching art for jade, crystal, agate, semi-precious stone, seal, elegant stone, antique, marble tombstone, ceramic, 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-treatments to increase surface adhesion.

5. Burr processing: Removal of burrs from bakelite, plastic, zinc, aluminum die-casting products, electronic parts, magnetic cores, etc.

6. Stress relief processing: aerospace, defense, precision industry parts, rust removal, paint removal and matting, refurbishment and other stress relief processing.
