Audited Supplier Industrial carbon black is a highly dispersed black powdery substance produced by the cracking and incomplete combustion of hydrocarbons (hydrocarbons such as oil or natural gas). It is mainly composed of carbon elements, and the microcrystals have a quasi-graphite structure. , and are concentrically oriented, and their "particles" are composed of nearly spherical or other irregularly shaped aggregates.
Characteristics of carbon black:
1. The best black pigment.
2. Almost the cheapest paint.
3. The pigment with the strongest tinting power and hiding power.
4. Visually neutral.
5. The most stable pigment, heat-resistant, chemical-resistant, and light-resistant.
Carbon black uses:
Mainly used as reinforcing agent and filler for rubber, its consumption is about half of rubber consumption. Carbon black for rubber accounts for 94% of the 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, cosmetics and polishing pastes.
In addition, there are many types of carbon black, and different types of carbon black have different functions and properties. And some carbon blacks can be processed into carbon black types with different properties through a series of special treatments.
