Description: Carbon black N330 belongs to high wear resistance furnace black. N330 is the most widely used high wear-resistant furnace black. The wear resistance of this product is slightly worse than that of medium and super wear resistant carbon black, but better than that of trough carbon black. This product is used for tire tread, cord compound, tire side and various rubber industrial products. This product is a kind of carbon black with good reinforcing property. It can give the compound better tensile property, tear resistance, wear resistance and elasticity. The rolling loss of the passenger tyre used in this product is only greater than N351 in N300 series, which is smaller than other varieties. It has good dispersion and extrusion performance in rubber compound. It is suitable for all kinds of synthetic rubber and natural rubber.

Carbon black is produced by incomplete combustion or pyrolysis of natural gas or high aromatic hydrocarbon oil in the reactor. This kind of carbon black is called furnace black, and it is the largest and most diverse type of carbon black N330. The distinct difference between furnace blacks and groove blacks and hot cracking blacks is that the degree of melting or coalescence of particles can be adjusted according to different uses. Therefore, the same particle size range of furnace blacks can be divided into several derivatives with different structures.

Furnace black production is characterized by the combustion of fuel in the reactor to provide the heat required for the cracking of raw materials. Combustion and pyrolysis occur simultaneously. According to the different forms of raw materials used, the production of furnace black can be divided into gas furnace method and oil furnace method. The raw materials and fuels used in the gas furnace process are natural gas. The fuel of oil oven process can be natural gas, coke oven gas or liquid hydrocarbon. The raw material is high aromatic oil, such as ethylene tar and anthracene oil. Reactor is the core equipment in the production process of furnace black (see figure). Reaction furnaces with different sizes are needed to produce different kinds of blacks. Air and fuel are burned in the reactor. The raw materials are atomized and sprayed into the burning flame. Carbon black is produced by pyrolysis at high temperature. Carbon black is suspended in the residual gas to form smoke. The flue gas is further cooled by air preheater and oil preheater after quenching. Finally, it is fed into bag filter. The separated carbon black is sent to granulator for granulation, and then dried in dryer.
