Product Description
Introduction to white corundum:
White corundum with industrial alumina powder as raw material, regularly over 2000 degrees in the arc after cooling in high temperature melting, through crushing, shaping, magnetic separation to iron, screen is divided into a variety of particle size, the dense texture, high hardness, granular form sharp corners, suitable for making ceramic, resin consolidation abrasive and grinding, polishing, sandblasting, precision casting, precision casting special corundum), can also be used for manufacturing high-grade refractory materials. White corundum is a kind of high-grade refractory raw material, the main crystal phase is alpha -Al2O3, white color. It has the characteristics of large volume density, low porosity, volume stability and good thermal shock resistance. It is suitable for large steel castings, especially for shell making materials of alloy casting mould, core sand, coating and investment casting. White corundum sand and powder are ideal materials to replace zircon sand powder as surface material in precision casting. White corundum is classified by mesh size: white corundum segment sand, fine powder, fine powder and grain size sand.
USES of white corundum:
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 deformizing agent removal, ceramic surface black spots, * color removal, painting regeneration.
2, beautification processing: all kinds of gold, K gold ornaments, precious metal products extinction or fog treatment, crystal, glass, corrugated, acrylic and other non-metallic fog processing and can make the processed surface into a metallic luster.
3, etching processing: jade, crystal, agate, semi-precious stone, seal, ya shi, antique, marble tombstone, ceramic, wood, bamboo, etc.
4. Pre-treatment and processing: TEFLON, PU, rubber, plastic coating, ROLLER, electroplating, metal spray welding, titanium plating, etc., to increase the surface adhesion.
5, rough edge processing: bakelite, plastic, zinc, aluminum die casting products, electronic parts, magnetic core, etc.
6, stress relief processing: aerospace, national defense, precision industry parts, rust removal, paint extinction, renovation, such as stress relief processing.
7. Electronic parts processing: fog and etching of silicon chips, removal of impurities on the back of wafers, overflow of packaging of electronic parts, removal of printed words on the surface of finished products, electrothermal cleaning of ceramics
8. Mold processing: sandblasting on the surface of general mold, fog treatment after mold bite, wire cutting mold, glass mold, tire mold, conductive rubber mold, shoe mold, electrowood mold, electroplating mold, key mold, plastic products mold.
9. Processing of large industrial crops: rust removal, paint removal, maintenance and automatic mist treatment of large plate glass for large work pieces such as oil tank, chemical tank, hull, copper structure, iron house, container, automobile industry, etc.
10, glass processing: all kinds of technology glass blasting
