Black carbon is a kind of chemical raw material. According to its use, it’s usually divided into rubber-grade carbon black, color carbon black and conductive carbon black. Black carbon powder is conductive carbon black. Its purity is high and carbon content reaches 99.5% or more. It has more developed branch structure and less surface oxygen content than other carbon black pigment powder. Therefore, it has some unique and excellent performance such as high conductivity, strong adsorption and good dispersion performances. Because of these excellent performance, it can not only meet the use requirement of batteries but also improve the discharge performance. In addition, it’s the raw material of conductive rubber, conductive plastic, radio components, fibers, anti-static products.
We adopt the calcium carbide method to produce black carbon powder. In other words, first use calcium carbide to make acetylene gas, after purification, isolate acetylene gas from air under high temperature for cracking, then after cooling, collect the black powder-like material. Its main component is elemental carbon, and it contains a small amount of oxygen, hydrogen and so on. Acetylene carbon black powder is a kind of pyrolysis carbon black. Its main characteristic is the developed branch structure, high liquid absorption, good conductivity. And its chemical properties are quite stable, it is not easy to react with acid, alkali and water. As an excellent basic chemical raw material, it’s mainly used in dry batteries, batteries, lithium batteries, special tires and tire capsules, absorbing materials, conductive, anti-static rubber, plastics, cables and other industries.
Acetylene carbon black is of medium grain size, with high structure, high purity, low ash and volatilization content, so the resistivity is very low. When acetylene carbon black is produced, it’s quite fine ab powder with low performance density, and it has 3 products, the powder product, the compressed product and the granulation product.
Jiaozuo Chengyuan New Material Co., Ltd., a trusted supplier of black carbon, provides cheap ab powder price. Buy high quality acetylene carbon black powder from us!

The raw material calcium carbide and water are put into the catalyst, after reaction, get acetylene gas, then after purification, and collect with the gas cabinet. Then isolate the collected acetylene gas at high temperature in the cracking furnace for cracking, then after cooling, collect the black powder-like material. Through the compressor, compress the fluffy acetylene carbon black properly before packaging and storage.

1.The acetylene carbon black is non-hazardous chemical, but its surface has hygroscopicity, so damp-proof measures are necessary. Usually three-tier packaging (inner kraft paper bag, the middle layer of plastic bags, and the outer plastic woven bags) is adopted, and moisture-proof kraft paper bags, ton bags can be used for package. Customers can also request the use of PE bags and other special packaging.
2.The product should be stored in a cool, dry, ventilated warehouse, away from the sources of fire and heat, and isolated from the oxidant. It should not be moisturized, hooked, pulled, thrown or pressed forcibly. For leakage, the fallen carbon black shall not be mixed into the product.
3.In work, people should wear masks and work clothes to prevent inhalation; after work, have a shower and change clothes to keep the body clean. If there is a fire, use water and other fire-fighting equipment to put out the fire.
