Small sandblasting machine silicon carbide
Product name: black silicon carbide, special abrasive for small sandblasting machine
Product model: 16-400#
It is widely used in sandblasting, grinding and polishing, emery wear-resistant floor, precision casting mold shell production.
Silicon carbide has stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance. In addition to being used as abrasives, there are
Many other uses, such as: coating silicon carbide powder on the inner wall of the turbine impeller or cylinder block with a special process to improve its resistance
It can prolong the service life by 1~2 times; it is made of high-grade refractory material, which is heat-resistant, small in size, light in weight and high in strength.
The effect is good. Low-grade silicon carbide is an excellent deoxidizer, it can speed up the steelmaking speed, and facilitate the control of chemical composition, improve the quality of steel. In addition, silicon carbide is also widely used to make silicon carbide rods for electric heating elements.
Silicon carbide has great hardness and excellent thermal conductivity. It is a semiconductor and can resist oxidation at high temperatures.
Black silicon carbide is made of quartz sand and petroleum coke as the main raw materials. It is smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum. It is brittle and sharp, and has certain electrical and thermal conductivity. .Use it to make abrasive tools, suitable for processing low tensile strength metal and non-metal materials, such as gray cast iron, non-ferrous metals, stone, leather, rubber, etc., and also widely used in refractory materials, metallurgical additives
