Quality corundum size sand blasting corundum abrasives Luoyang Wei Cheung

Quality corundum size sand blasting corundum abrasives Luoyang Wei Cheung corundum is bauxite, corundum and iron block inside anthracite firing almost no impurities of high purity corundum block, pick After the block level and the rest is secondary and tertiary corundum corundum, and because of the high purity corundum (over 95%) so the price will be less than the yield secondary, tertiary, much higher, a corundum used for refractories and abrasives. corundum, common name, also known as carborundum, is bauxite, coke (or anthracite), three types of raw iron in an electric furnace at 2,000 degrees melting reduction obtained through the brown artificial corundum, it is for this name. Corundum main chemical composition is AL2O3, its content 94.5% -97%, and the other containing a small amount of Fe, Si, Ti and the like. After the plastic from the mill grinding, magnetic separation to iron, screening into a variety of size, its dense texture, high hardness, formation of spherical particles, for the manufacture of ceramics, resins and high abrasive grinding, polishing, sand blasting, precision casting etc., it can also be used to manufacture advanced refractories. Grade corundum corundum main component is alumina, aluminum content also graded to distinguish between the lower aluminum content will lower the hardness of. Corundum color: corundum is the main purpose was brown corundum: the corundum is mainly used for blasting abrasives, water filtration. Abrasive blasting Scope: workpiece material, blasting purpose technological requirements; stainless steel, surface decontamination, in addition to the slag and matte effect; iron piece, rust, decontamination, descaling increased plating, coating attached focus; aluminum parts, descaling, surface hardening, Polishing effect; copper artifacts go oxidation Pia light effects; frosted crystal glass products, carved patterns; plastic products (hardwood products) matt effect; denim and other special fabrics, plush effect processing and pattern corundum Density: Density divided into two types called corundum, one corundum bulk density, particle density and second, corundum. Bulk density: 1.53 ~ 1.99g / cm3, abrasive abrasive bulk density and particle size, particle size composition, species, particle shape and other factors are related, in general, larger than the fine-grained coarse-grained abrasive abrasive bulk density and particle size of the abrasive mix a bulk density greater than the density of a single particle. Particle density: 3.95 ~ 4.0 / cm3, abrasive particle density is the unit volume (excluding open pore volume) contained within the abrasive quality.
