White fused alumina 

A type of artificial abrasive. Aluminum trioxide (Al2O3) has a content of over 99% and contains a small amount of iron oxide, silicon oxide, and other components, appearing white.

The product granularity is produced according to international standards and national standards, and can be processed according to user requirements. The general particle size is F4-F220, and its Chemical composition varies according to 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 grinding machine, the particles are mostly spherical, with a dry and clean surface that is easy to bond with the binder

Application scope:

     Mechanical engineering, abrasive grinding tools, abrasives 

Product advantages:

1. Does not affect the color of the processed parts;

2. Can be used for sandblasting in processes where residual iron powder is strictly prohibited;　

3. Micro powder level is very suitable for wet sandblasting and polishing operations; 　

4. Fast processing speed and high quality; 　

5. The extremely low content of iron oxide is suitable for sandblasting operations that strictly prohibit iron residue; 　

6. Go through the pickling step to remove impurities.

Purpose:

Scope of application: White corundum abrasive is suitable for surface beautification treatment of various high-end products, processes, or hardware products. After sandblasting, the surface is clean and white without any impurities, eliminating cleaning troubles. Fine sized white corundum can be used as the first for polishing and grinding. It can also be used as an additive for various products. It can be used for solid and coated abrasives, wet or dry or spray sand, suitable for ultra precision grinding and polishing in the crystal and electronic industries, as well as making advanced refractory materials. Suitable for processing hardened steel, alloy steel, high-speed steel, high carbon steel and other materials with higher hardness and tensile strength. It can also be used as a touch media, insulator, and precision casting sand. Remove rust, dirt, and oxide skin from iron workpieces, increase the adhesion of coatings and coatings; Aluminum workpieces are descaled, with surface strengthening and polishing effects; Matte effect of removing oxide skin of copper workpiece, crystal frosting of glass products, matt effect of carved pattern plastic products, plush processing and effect patterns of special fabrics such as Denim

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, and color painting regeneration.

2. Beautification processing: various gold, K-gold jewelry, precious metal products with matte or matte treatment, non-metallic matte processing of crystals, glass, ripples, acrylic, etc., as well as the ability to create a metallic luster on the surface of the processed product.

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

4. Pre treatment processing: Teflon, PU, rubber, plastic coating, rubber roller, electroplating, metal spray welding, titanium plating and other pre treatments to increase surface adhesion.

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

6. Stress relief processing: stress relief processing for aerospace, national defense, precision industrial parts, rust removal, paint removal, polishing, and renovation.
