Product name: grained sand of white fused alumina
specification: 150#
Introduction and application scope of white corundum:
White corundum is made of industrial alumina powder as raw material, which is melted at high temperature above 2000 °C in arc and cooled. After crushing and shaping, magnetic separation and iron removal, it is sieved into various particle sizes. It has dense texture, high hardness and sharp corner shape. It is suitable for manufacturing ceramics, resin consolidated abrasive tools, grinding, polishing, sandblasting, precision casting ( special corundum for precision casting ), etc., and can also be used to manufacture refractory materials.
MAIN APPLICATIONS
The white corundum abrasive is suitable for the surface beautification treatment of various products, processes or hardware products. The surface is white without any impurities after sandblasting, eliminating the trouble of cleaning. Fine white corundum can be the first of polishing and grinding. It can also be used as various product additives. Can be used as fixed coated abrasive, wet or dry or jet sand, suitable for crystal, electronic industry of ultra fine grinding, polishing and production of refractory materials. It is suitable for processing hardened steel, alloy steel, high speed steel, high carbon steel and other materials with hard hardness and high tensile strength. It can also be used as touch media, insulators and precision casting sand. Iron workpiece derusting, decontamination, oxide skin, increase coating, coating adhesion ; aluminum workpiece to remove oxide skin, surface strengthening, polishing effect ; copper workpiece to oxide skin matte effect, glass products crystal frosting, carved plastic products matte effect, denim and other special fabrics plush processing and effect patterns.
