Jiangxi black silicon carbide - Jiangxi black silicon carbide Zhengzhou Huan River Industrial company specializing in the production of black silicon carbide, black silicon carbide abrasive hardness than corundum class, cutting edge Ruifeng, brittle. Good thermal conductivity, heat dissipation, self-sharpening performance than corundum abrasives. Adapted to the ceramic, resin, rubber wheel, refractories manufacturing; gray cast iron, white cast iron, bronze, brass, minerals, aggregates, glass, leather, rubber, plastics and grinding heat-sensitive materials. Black silicon carbide abrasive blasting is also suitable for dry grinding, milling and freedom jewelry, jade, agate cutting and shaping, quality assurance, welcome to consult the discussion. Black silicon carbide purposes: (1) black silicon carbide SiC containing about 98.5%, which is higher than the toughness of green silicon carbide, mostly for processing low tensile strength of the material, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals and so on. (2) seals manufacturers in the production of silicon carbide seals, and 98% have joined the green silicon carbide powder as a filler. Produced silicon carbide mechanical seal ring with a light weight, low coefficient of thermal expansion, high hardness, high temperature strength at high temperatures has good size, corrosion resistance, strength and high modulus of elasticity, long service life . Can be used for radioactive, corrosive, toxic, flammable, explosive, high temperature, and many other complex working conditions. For petroleum, chemical pumps and rotary machinery using. Advanced Refractories (3) to be made, heat shock, small size, light weight high strength, good energy saving effect. (4) a low-grade silicon carbide (containing about 85% SiC) is an excellent deoxidizer, it may be used to accelerate the speed of the steel, and to facilitate control of chemical composition, to improve the quality of steel. (5) is also used extensively for the production of silicon carbide silicon carbide heating elements Zhengzhou Huan River Industrial specializing in the production of black silicon carbide, black silicon carbide abrasive hardness than corundum class, cutting edge Ruifeng, brittle.
