The carborundum take burnt etc. of quartz sand, petroleum as the main raw material, passing a heat of electric resistance but becoming, its degree of hardness lie in just of the jade and diamond, the machine strength is high in just jade, sex frailty but sharp.It have certain of electrical conductivity and transmit heat sex.Whet with its manufacture, be applicable to process a metals with low strength of anti- and nonmetal materials.Such as:The ash iron casting, have the color metals, stone material, leather, rubber...etc..Still used for the fire-proof material, metallurgy additive extensively.
The green carborundum green carborundum mode of production and the Hey carborundums are basic and same, just having different request to the original material, the crystallize body that the become pure the degree is high, there is higher degree of hardness.Make with it whet, suit to process the degree of hardness high, big material of brittleness.Such as:The nonmetal material of hard quality metal alloy, metal alloy , bearings steel, and high and hard frailty include:The glass, the electricity porcelain, quartz product, stone material;Also can make the deluxe fire-proof material and give or get an electric shock the hot module, electric appliances module. |
