Mainly used as rubber reinforcing agent and filler, its consumption is about half the consumption of rubber, rubber, carbon black carbon black accounts for 94% of the total, of which about 60% for tire manufacturing. In addition, as inks, paints and plastics and plastic products, colorants UV shielding agent. In many other products, such as electrodes, batteries, resistors, explosives, cosmetics and polishing paste, it is also important additives. Furnace black is mainly used for rubber, carbon black, the finer the particle size, the more excellent performance of its reinforcement; higher the degree of carbon black structure, and its modulus and modulus higher. Varieties of fine particle size of the reinforcement is mainly used for tire tread, the tire gives good wear resistance. Other parts of the tire, such as the sidewall, ply, belt buffer layer and the inner layer, requiring rubber song flex cracking resistance, resistant to ozone oxidation, has good elasticity and low heat properties, generally using more The semi-reinforcing type of coarse grain size (surface area less than 40m2 / g) furnace black.</p>
