Product Description

White Fused Alumina Grains to Make Emerypaper (XG-030)
Refractory grade 99.6% Al2O3 white fused alumina grit

Product process
White corundum using industrial alumina powder as raw materials, measures in the arc after cooling in more than 2000 degrees high temperature melting, plastic surgery to through crushing, magnetic separation to iron, screen is divided into a variety of particle size, dense texture, high hardness, particle formation Angle shape, is suitable for manufacturing ceramic porcelain, resin abrasive and grinding, polishing, sandblasting of consolidation, precision casting, precision casting special corundum), etc., can also be used for manufacturing high-grade refractory materials, codenamed "WA" international general standards, national standards, most for export, also has a certain supply of domestic users.

Usage
White corundum are suitable for all kinds of high-end product, process or beautify processing, hardware and other products surface after sand blasting surface clean without any impurities, cleaning trouble. Fine white corundum used as a polishing. Also can be used as additive in various products.
1. Surface machining: Metal oxide, carbon black, metallic or non-metallic surface decontamination rust removal, such as gravity die casting, rubber mold of oxides or removal of the debonding agent, ceramic surface black spots, color removal of uranium, coloured drawing or pattern.
2. Beautify processing: All kinds of gold, K gold, precious metals products of extinction or fog surface processing, crystal, glass, corrugated, the fog of the force that press a gram etc. Nonmetal surface and can make the machining surfaces into metallic luster.
3. Processing: Etching jade, crystal, agate, semi-precious stones, seal, stone, the stone of jas, antiques, marble tombstone, ceramic, wood, bamboo, etc. The etching of artists.
4. The pretreatment processing: TEFLON, TEFLON, PU, rubber, plastic, coating, rubber ROLLER (ROLLER), electroplating, metal spray welding, plating titanium before processing, increase the adhesion on the surface.
Burrs processing: Bakelite, plastic, zinc, aluminum die-casting products, electronic components, removing burrs of magnetic core, etc.
Pictures of stress relieving process: Aerospace, national defense, precision industrial parts, rust removal, in addition to paint the extinction, etc. The stress relieving process of repair.
