- Stainless steel sandblasted abrasive, white corundum grain size sand, 60 mesh, 80 mesh, 100 mesh
- White corundum is made of high-quality aluminum oxide powder as raw material, crystallized by electromelting, high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, stable thermal performance, it is slightly harder than brown corundum, slightly lower toughness, strong grinding ability, small calorific value, high efficiency. It can be made into an abrasive, which can be applied to grinding fine-grained abrasives such as high carbon steel, high speed steel and stainless steel; It can also be used for precision casting and advanced refractories.
- Physical and chemical indicators:

- 1. Does not affect the color of the workpiece;
- 2. It can be used for sandblasting in the process where iron powder residue is strictly prohibited;
- 3. Micro-powder 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.
- It is suitable for surface beautification treatment of various high-end products, crafts or hardware products. After sandblasting, the surface is white without any impurities, eliminating the trouble of cleaning. Fine white corundum can be used as an option for polishing and grinding, and can also be used as an additive for various products.
- 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, painting Rebirth.
- 2. Beautification processing: all kinds of gold, K gold jewelry, matte or matte treatment of precious metal products, matte processing of crystal, glass, corrugated, acrylic and other non-metallic surfaces, and can make the surface of processed objects into a metallic luster.
- 3. Etching processing: 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 roller (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. Force eliminates processing.
- Company Profile
- Henan Sicheng Grinding Technology Co., Ltd. was established in August 2010. The factory is located in West Farm, Gaocun Township, Xingyang City, Henan Province, with a registered capital of 2 million yuan and legal representative Ding Shouxin. The company covers an area of 6,000 square meters and has 25 employees. Our company mainly produces corundum products mainly made of white corundum, including white corundum grain size sand, micropowder, fine powder, and section sand, with an annual output of 6,000 tons.
