Green silicon carbide

Product description

Green silicon carbide is made of petroleum coke and high-quality silica by high-temperature smelting in resistance furnace with salt as additive. It is green crystal, brittle and sharp, and has certain thermal conductivity and conductivity. The microhardness of silicon carbide is 9.3, the microhardness of silicon carbide is 2940-3300kg / mm2, the Knoop hardness is 2670-2815kg / mm2, which is higher than that of corundum in abrasives, and next to diamond, CBN and BCC. The density is generally considered as 3.20-3.25g/cm3. The natural packing density of silicon carbide abrasive is between 1.2-1.6g/cm3, and the specific gravity is 3.20-3.25g/cm3.

Green silicon carbide micro powder is made of high-quality large crystalline silicon carbide block by crushing, vertical ball mill particle shaping, acid pickling water, precise hydraulic classification, high-temperature drying after natural settlement, stable quality, good crystallization, high surface cleanliness, no large particles, small content of fine particles, concentrated particle size distribution, high grinding efficiency, suitable for all kinds of precision grinding processing, uniform surface of processed workpiece , no scratches.

Green silicon carbide spherical sand and micro powder are the second shaping products after Raymond grinding. They have the characteristics of small particle edges and corners, good hydrophilicity, high grinding efficiency and long working life.

Product model and use

The green silicon carbide segment sand is produced by Bama restraint sand machine, with rounded particles. As the grinding medium, it can perfectly replace the high price zirconia ball. In the ultra-fine powder grinding of green silicon carbide photovoltaic edge material, it has perfect grinding effect and does not affect the product content

Green silicon carbide grain size sand is mainly used for abrasive manufacturing and sand blasting media for surface treatment.

Manufacturing of grinding tools: resin grinding wheel, ultra-thin cutting piece, marble grinding wheel, diamond grinding plate, etc

Surface treatment: grinding hard alloy, hard brittle metal and non-metallic materials - quartz glass, optical glass, piezoelectric ceramics, etc.

Green silicon carbide powder can be used for precision grinding of hard glass, slice of single crystal silicon and polycrystalline silicon bar, precision grinding of single crystal silicon chip, processing of super hard metal, processing of soft metal such as copper and copper alloy, processing of various resin materials, etc.
