Carbon black is an amorphous carbon. It is a light, loose and extremely fine black powder with a very large surface area ranging from 10~3000m2/g. It is a carbonaceous material (coal, natural gas, heavy oil, fuel oil, etc.) that undergoes incomplete combustion under insufficient air conditions. Or the product of thermal decomposition. It can be used as a black dye, used to make Chinese ink, ink, paint, etc., and also used as a reinforcing agent for rubber.
1. Conductive carbon black
Conductive carbon black has two physical forms, powder and granular. The product has the characteristics of low resistance, high conductivity, easy dispersion, small addition amount, and stable quality. It is suitable for conductive applications in various different industries, such as antistatic and lithium battery products.
2. Pigment Carbon Black
Pigment carbon black has two hues, red phase and blue phase, and two physical forms of powder and granules. It has the characteristics of high blackness, high coloring, high dispersion, and stable quality. It is widely used in color masterbatches, paint inks, rubber, Plastic, wire and cable, leather, color paste, powder coating, paper, construction and other industries.
3. Acetylene carbon black
Acetylene carbon black has the characteristics of high purity, high structure, low resistance, low ash content, low volatile content, and stable quality. It is mainly used for batteries as electro-absorbent fluid, and also used for conductive, antistatic and thermal conductive rubber products, as well as conductive coatings, plastics In production.
4. Insulating carbon black
Insulating carbon black has the characteristics of ultra-high resistance value, high blackness, high coloring, easy dispersion, stable quality, etc., and can be used for high-quality printing and copying inks, high-insulating plastics, synthetic fibers, insulating rubber and other insulating products.
5. Spray carbon black
Spray carbon black is a large particle size, high structure furnace carbon black with a particle size of 100~130nm. It is mainly used as a reinforcing filler for rubber. This product can be filled in a large amount of rubber with good processing performance. Extrusion search is small. Vulcanized rubber has high elasticity, low heat generation, small deformation, good low temperature performance, high tensile stress, but low tensile strength and elongation rate.
6. Metallurgical carbon black
Metallurgical carbon black is an important raw material for the metallurgical industry. It is developed on the basis of improving the production process of natural gas semi-reinforcement and furnace black. It is mainly used as a carbon matching material in the cemented carbide smelting process, and can also be used as a graphite tube Furnace materials for resistance furnace.
Others include lamp smoke carbon black, mixed gas carbon black, water-soluble carbon black, rubber carbon black, building material carbon black, channel carbon black and other varieties.
