White corundum product introduction and use of white corundum
White corundum is a more common abrasive in the abrasive market, which is made of industrial alumina as raw material and melted at high temperature above 2000 degrees in the arc. The main chemical composition of white corundum sand is AL2O3, its content is 98.65% -99.37%, and contains a small amount of Fe, Si, Ti and so on. White corundum particle size sand is sometimes called number sand, and segment sand is different, it has a fixed particle size, like F sand, P sand, W sand belong to the range of particle size sand. White corundum is suitable for the manufacture of ceramic, resin-consolidated abrades, grinding, polishing, sandblasting, precision casting, etc., and can also be used to make refractory materials. The properties of white corundum are many such as wear resistance; Brittle; Toughness; Corrosion resistance; Reduce dust; Impact resistance; Not afraid of fire; Metal aggregate can also prevent static electricity and so on.
White corundum fine-grained products are composed of fine particles, fine particles have a larger surface, more contact between the particles, so the hardness is higher. When the hardness is the same, the porosity is larger. The large contact surface also increases the forming pressure relatively. Coarse particles have larger pores, while fine particles have smaller pores. The abrasives used in the manufacture of high-density products use mixed particle sizes so that different particle ratios can make products with high filling density and low porosity. The manufacture of low porosity products can consider a more strict control of the particle size range.
White corundum product uses
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 release agent removal, ceramic surface black spots, uranium color removal, painting rebirth.
2, beautify processing: all kinds of gold, K gold jewelry, products of matting or fog surface treatment, crystal, glass, corrugated, acrylic and other non-metallic fog surface processing and can make the surface of the processed metal luster.
3, etching processing: jade, crystal, agate, semi-precious stone, elegant stone, antique, marble tombstone, ceramic, wood, bamboo and other etching artists.
4, pre-treatment processing: TEFLON (TEFLON), PU, rubber, plastic coating, rubber ROLLER (ROLLER), electroplating, metal spray welding, titanium plating and other prior treatment, so that the surface adhesion increases.
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, precision industry parts, rust removal, paint extinction, repair and other stress relief processing.
