White corundum is made from industrial alumina powder as raw material. It is smelted at high temperature above longitude in the arc and then cooled. It is crushed, shaped, magnetically separated to remove iron, and screened into various particle sizes. Its texture is dense. , high hardness, grains formed into sharp angles, suitable for manufacturing ceramics, resin-bonded abrasives, grinding, polishing, sandblasting, precision casting (special corundum for precision casting), and can also be used to manufacture advanced refractory materials&. White corundum is a high-grade refractory raw material with a main crystal phase of '&' and a white color. It has the characteristics of high volume density, low porosity, good volume stability and thermal shock resistance. It is suitable for large steel castings, especially alloy castings, core surface sand, coatings and investment casting shell materials. It can also be used as semi-finishing and fine grinding abrasives for quenched steel, alloy steel, etc. White corundum sand and powder are the most ideal materials to replace zircon sand powder as surface material in precision casting, and the castings processed with it have good smoothness. White corundum is classified according to mesh size: white corundum segment sand, micro powder, fine powder, and granular sand.
Use of white corundum:
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 Remove the black spots on the ceramic surface, remove the uranium color, and repaint it.
Beautification processing: Matte or matte processing of various gold, gold jewelry, precious metal products, matte processing of crystal, glass, corrugated, acrylic and other non-metals, and can make the surface of the processed object have a metallic luster.
Etching processing: Etching art for jade, crystal, agate, semi-precious stones, seals, elegant stones, antiques, marble tombstones, ceramics, wood, bamboo chips, etc.
Pre-treatment: Teflon rubber, plastic coating, rubber roller (RR), electroplating, metal spray welding, titanium plating and other pre-processing to increase surface adhesion.
, Burr processing: Burr removal of bakelite, plastic, zinc, aluminum die-casting products, electronic parts, magnetic cores, etc.
Stress relief processing: Stress relief processing for parts in aerospace, national defense, precision industry, rust removal, paint removal and matting, renovation, etc.
, Electronic parts processing: matte surface and etching of silicon chips, removal of impurities on the back of wafer, glue spillage from electronic parts packaging, removal of printing on the surface of finished products, cleaning of ceramic electric heating
, mold processing: general Sandblasting of mold surface, matte treatment after mold bite, wire cutting mold, glass mold, tire mold, conductive rubber mold, shoe mold, bakelite mold, electroplating mold, button mold, plastic product mold.
Processing of large workpieces: rust removal, paint removal, repair of large workpieces such as oil tanks, chemical tanks, ship hulls, copper structures, iron houses, containers, automobile industry, etc. and automatic matte treatment of large flat glass.
Glass processing: Sandblasting of various craft glass
