Product Description

White Fused Alumina Powder Fused Calcined Alumina Casting Molds Fused Alumina

Use of the white corundum abrasive material
 

Surface processing

It can remove metal oxide layer, carbide black skin, metal or non-metal surface rust, such as oxide or separation agent used to remove gravity die casting mold, rubber mold, remove ceramic surface black spots, uranium color and make the color rebirth, etc. 

 

Beautification processing

Used in all kinds of gold, K gold jewelry, precious metal products extinction or fog surface processing, can also be crystal, glass, ripple, acrylic and other non-metal fog surface processing, but also can make the surface of processing into metallic luster.

 

Etching processing

Suitable for jade, crystal, agate, semi-precious stone, seal, elegant stone, antique, marble, tombstone, ceramics, wood, bamboo, other etching artist.

 

Pre-treatment and processing aspects

Use in ferrofluoron (TEFLON), PU, rubber, plastic coating, rubber rolling barrel (ROLLER), electroplating, metal spray welding, titanium plating, etc., can increase the surface adhesion.

 

Maoyan processing

Can remove electric wood, plastic, zinc, aluminum die-casting, electronic parts, magnetic core and other edges.

Stress elimination and processing aspects

For aerospace, national defense, precision industry parts of rust, polishing, renovation and other stress elimination processing.

 

Mill making

The grinding tool made of white corundum is suitable for the grinding of high carbon steel, high speed steel and quenching steel, can also be used for grinding and polishing materials, can also be used as precision casting sand, spraying materials, chemical catalyst, special ceramics, high quality refractory materials, etc. Among them, electrofused white corundum is the main raw material in the production of high-grade uncertain and fixed shape refractory materials (such as large ladle pouring material, middle and high-grade iron trench pouring material, spray supplement, prefabricated parts, etc.) .

 

Other applications

It does not affect the color of processing parts, and can be used for sandblasting in the manufacturing process of prohibited iron powder residue. It is very suitable for wet sandblasting and light grinding, and the amount of iron oxide is very low and suitable for sandblasting operation of prohibited iron residue; it can be used for atomization aesthetic processing of glass, sandblasting, silicon crystal cutting, etc
