High Purity White Fused Alumina Grit
WHITE FUSED ALUMINA DESCRIPTION
White corundum is a kind of artificial abrasive. Aluminum oxide (Al2O3) content in more than 99%, and contains a small amount of iron oxide, silicon oxide and other components, is white. The outstanding feature is the small crystal size and impact resistance if used in an automill Processing broken, particles for spherical particles, dry surface clean, easy to bond. White corundum with industrial alumina powder as raw material, in the arc after 2000 degrees of high temperature after cooling, after grinding Shaping, magnetic separation to iron, screen into a variety of particle size, its dense texture, high hardness, the formation of sharp grain, suitable for manufacturing pottery Porcelain, resin consolidation grinding tools and grinding, polishing, sand blasting, precision casting (investment casting special corundum), can also be used to manufacture high-grade refractory materials
White corundum is made of industrial alumina powder and refined by modern new unique technology. Sand blasting abrasive has the characteristics of short grinding time, high efficiency, good benefit and low price. The main components are: Aluminum oxide (Al2O3) content in more than 98%, and contains a small amount of iron oxide, silicon oxide and other components, is white, in the arc by more than 2000 degrees of high temperature melting after cooling made, by grinding and shaping, magnetic separation to iron, screen into a variety of granularity, its dense texture, high hardness, the formation of a sharp grain. White corundum hardness is slightly higher than brown corundum, toughness is slightly lower, high purity, good self-sharpening,strong grinding ability, small caloric value, high efficiency, acid and alkali corrosion resistance, high temperature thermal stability. Made of white corundum sand, suitable for grinding fine grained abrasives such as high carbon steel, high speed steel and stainless steel. White corundum sand can also be used for precision casting and high-grade refractory materials.

SCOPE OF APPLICATION
white corundum abrasive is suitable for all kinds of high-end products, technology or hardware products surface beautification treatment, sandblasting surface white without any impurities, remove the cleaning trouble. Fine white corundum can be used as polishing head. Can also be used as a variety of product additives. Can do solid and coated abrasive tools, wet or dry or jet sand, suitable for crystal, electronic industry super fine grinding and polishing and make high grade refractory materials. It is suitable for processing hardened steel, alloy steel, high speed steel, high carbon steel and other hard hardness, high tensile strength materials. It can also be used as contact media, insulator and precision casting sand. Iron workpiece rust removal, decontamination, removal of oxidation skin, increase the coating, coating adhesion; Aluminum workpiece oxidation skin, surface strengthening, polishing effect; Copper workpiece to remove skin matte effect, glass products crystal matte effect, patterned plastic products matte effect, denim and other special fabric plush processing and effect pattern.
1, surface processing: metal oxide layer, carbide black, metal or non-metal surface rust removal, such as gravity die casting mold, rubber mold oxide or free agent removal, ceramic surface black spots, uranium color removal, painting rebirth.
2, beautify processing: all kinds of gold, K gold jewelry, precious metal products of extinction or fog surface treatment,
crystal, glass, corrugated, acrylic and other non-metallic fog surface processing and can make the surface of the processing into metal luster.
3, etching processing: jade, crystal, agate, semi-precious stones, seals, elegant stone, antiques, marble tombstones, ceramics, wood, bamboo pieces of etching artists.
4, pretreatment processing: TEFLON (TEFLON), PU, rubber, plastic coating, rubber barrel (ROLLER), electroplating, metal spray welding, titanium plating before treatment, so that the surface adhesion increase.
5, raw edge processing: bakelite, plastic, zinc, aluminum die casting products, electronic parts, magnetic core and other raw edge removal.
6, stress relief processing: aerospace, national defense, precision industry parts, rust removal, paint extinction, repair and
other stress relief processing.
