What is the role and use of carbon black

There are still many functions of carbon black. For example, it mainly plays the role of reinforcing agent and filler in rubber, it mainly plays the role of coloring in ink and paint, and it is used as a UV shielding agent in plastic products. It is also an important additive in many other products, such as dry batteries, resistors, explosives, cosmetics and polishing pastes. The main role played in different industries is different.

The raw material of carbon black is high temperature coal tar

Coal tar is a kind of carbon black raw material. At present, the raw material oil used for domestic carbon black production is mainly coal tar. quality and yield. The main requirements for the feedstock oil of the carbon black production team are high aromatics content and low asphaltenes and impurities. At present, many ordinary carbon blacks in China use high-temperature coal tar, but if the quality of carbon black is very high, and it belongs to the kind of special carbon black, coal tar cannot be selected as the raw material. Instead, anthracene oil, natural gas, etc. are selected as raw materials for carbon black.
