In industry, silica mill is usually used to micronize raw materials Processing to obtain ultrafine silica powder. The demand for silica is relatively large, but the purity requirements are not very high. At present, the domestic situation is more favorable to the industry, which is mainly reflected in the general increase in industrial applications. In particular, the attention to the industry has obviously increased greatly. At the same time, investment and preferential policies for the silica glass manufacturing industry have also increased. more and more.
Ultra-fine silica has a very significant reinforcing effect on various rubbers , among which the reinforcing effect on silicone rubber is outstanding. White carbon black is a white reinforcing agent whose reinforcing effect is second only to the corresponding furnace carbon black. Compared with the corresponding furnace carbon black reinforced vulcanized rubber, the vulcanized rubber containing a certain amount of silica has the advantages of high strength, large elongation, high tear strength, high hardness, and good insulation. Usually, carbon black and silica black are used together to obtain better overall performance.
