In which six main areas can carbon black be applied?

Carbon black is one of the indispensable important chemical raw materials in my country's modern economy. Carbon black is of great significance to the development of the national transportation industry, the realization of agricultural mechanization, the strengthening of national defense construction, and the improvement of people's material life and spiritual civilization.

1. Rubber
Carbon black is an important reinforcing agent for rubber products. In carbon black for rubber, about 75% of carbon black is used to manufacture various types of tires, such as automobile tires, tractor tires, aircraft tires, bicycle tires, electric tires, etc.; the rest is used to manufacture other rubber products, such as Rubber hose, tape, rubber shoes, etc. Carbon black has very excellent reinforcing properties, improves the wear performance of tires, greatly increases the mileage of tires, and can also improve the physical and mechanical properties of rubber compounds such as tensile strength and tear strength.
2. Ink
Carbon black is the main pigment of black ink. Most printing inks use high-quality pigment carbon black, and the basic properties of carbon black affect the quality of ink and printed matter to a large extent. The requirements of printing inks for carbon black are mainly blackness, hue, flow phase, viscosity, dryness and thixotropy.
3. Paint
Carbon black has the stability to chemical substances, light and heat, which is unmatched by other black inorganic pigments and organic dyes. When carbon black is added to paint, it has less reflection, high blackness, good weather resistance and strong tinting power.
4. Plastic
Carbon black for plastics accounts for a large proportion of non-rubber applications. Not only can it be colored or toned, but it can also prevent UV aging, antistatic or conduct electricity. In order to make carbon black have a good dispersion in plastics, carbon black is usually pre-dispersed in a certain medium, called masterbatch or masterbatch; and then the wood is diluted with an appropriate proportion of plastic.
5. Synthetic leather
Carbon black is one of the important auxiliary materials for the production of synthetic leather. In the production process of synthetic leather, as a black colorant for coating polyurethane solution, it is mainly used in the layer close to the surface layer. Carbon black is an indispensable raw material for the preparation of dark synthetic leather.
6. Other fields
In addition to the above application range, carbon black is also used in dry batteries, electrical appliances, electronic components, high-purity graphite, printing and dyeing, gunpowder, electrostatic copying toner, etc. In these fields, carbon black also plays a great role.
