Introduction And Characteristics Of Carbon Black

Carbon black,molecular weight: 12.01

Industrial carbon black is a highly dispersible black powdery substance produced by the cracking and incomplete combustion of hydrocarbons (oil or natural gas and other hydrocarbons). Pigment carbon black is mainly composed of carbon elements, while microcrystalline It has a quasi-graphite structure and is concentrically oriented, and its "particles" are composed of aggregates of nearly spherical or other irregular shapes.

Carbon black has the following characteristics:

1. One of the best black pigments.

2. Relatively cheap pigments.

3. One of the pigments with the strongest tinting power and hiding power.

4. The visual sense is neutral.

5. The most stable pigment, heat resistance, chemical resistance, and light resistance.

Uses:

Mainly used as a reinforcing agent and filler for rubber. Its consumption is about half of rubber consumption. Rubber carbon black accounts for 94% of total carbon black, of which about 60% is used in tire manufacturing. In addition, it is also used as a colorant for inks, coatings and plastics, and as a UV shielding agent for plastic products. It is also an important additive in many other products, such as electrodes, dry batteries, resistors, explosives, cosmetics and polishing pastes. Carbon black for rubber, pigment carbon black and conductive carbon black. Carbon black for rubber, such as tire industry, rubber seals, shock absorbers, etc., with a certain amount of carbon black in rubber products can play a role of reinforcement and filling to improve the performance of rubber products. Pigment carbon black is mainly used as black pigment in ink, paint and other industries. Conductive carbon black uses the low resistance or high resistance properties of some carbon blacks to make it become conductive carbon black in different products, such as conductive rubber, radio components, etc. ·The application of carbon black in the plastics industry·Before choosing, it is necessary to determine its use, such as coloring, UV protection, or conductivity, etc.
