White corundum is an artificial abrasive. The content of aluminum trioxide (Al2O3) is above 99%, and it contains a small amount of iron oxide, silicon oxide and other components, which is white. The product granularity is produced according to international standards and national standards, and can be processed according to the granularity required by users. Generally, the particle size number is F4~F220, and its chemical composition varies according to the particle size. Outstanding features are small crystal size and impact resistance. If crushed by a self-grinding machine, the particles are mostly spherical, the surface is dry and clean, and it is easy to combine with the binder.

Product uses of white corundum:

White corundum abrasive is suitable for beautifying the surface of various high-end products, crafts or hardware products. After sandblasting, the surface is white and free of any impurities, thus avoiding the trouble of cleaning. Fine white corundum can be used as a polishing head. And can also be use as an additive for various products. It can be used as solid and coated abrasive, wet or dry or sandblasting, and is suitable for ultra-precision grinding and polishing in crystal and electronic industries and making advanced refractories. Suitable for processing hardened steel, alloy steel, high-speed steel, high-carbon steel and other materials with high hardness and high tensile strength. It can also be used as contact medium, insulator and sand for precision casting. Derusting, decontamination and descaling of iron workpieces to increase the adhesion between coating and coating; Rust removal of aluminum workpiece, surface strengthening and polishing; Matte effect of rust removal of copper workpieces, matte effect of crystal glass products, matte effect of patterned plastic products, plush processing of denim and other special fabrics and effect patterns.

1, surface treatment: metal oxide layer, carbide black skin, metal or nonmetal surface rust removal, such as gravity die casting mold, rubber mold oxide or release agent removal, ceramic surface black spots, uranium color removal, paint regeneration.

2. Beautifying processing: matte processing of all kinds of gold, K-gold ornaments and precious metal products, matte processing of non-metals such as crystal, glass, ripple and acrylic, and the surface of the processed products has metallic luster.

3. Etching: an artist who etches jade, crystal, agate, semi-precious stones, seals, yashi, antiques, marble tombstones, ceramics, wood and bamboo chips.

4. Pretreatment: Teflon, PU, rubber, plastic coating, cots, electroplating, metal spray welding, titanium plating, etc. , to increase the surface adhesion.

Burr processing: bakelite, plastic, zinc, aluminum die casting, electronic parts, magnetic cores, etc.

6. Stress relief: stress relief, rust removal, paint removal, extinction and renovation of parts in aerospace, national defense and precision industries.
