Carbon black plays a very important role in our daily life. It is an indispensable chemical raw material. What are the varieties of pigment carbon black? How to classify?
The main raw materials for carbon black production are coal tar, ethylene tar and other raw material oils. In my country, coal tar is the main raw material. Carbon black is mainly used in tires, plastics, coatings and other industries.
Carbon black is usually divided into rubber carbon black, pigment carbon black, and conductive carbon black according to different uses. Among them, pigment carbon black is widely used in the market, and the details of its use are as follows:
Sealants, color pastes, color masterbatches, inks, coatings, paints, special carbon blacks and pigment carbon blacks for building materials.

The Chinese national standard GB/T7044-1993 "Technical Conditions for Pigment Carbon Black" stipulates the name, classification and code of pigment carbon black. Generally divided into high, medium and low pigment three categories. According to its blackness and manufacturing method, it can be divided into: high pigment tank black (HCC), high pigment furnace black (HCF), medium pigment tank black (MCC), medium pigment furnace black (MCF), ordinary pigment tank black (RCC) ), regular pigment furnace black (RCF) and low pigment furnace black (LCF).
