Description

Technical Field

[0002] Acetylene black is a nano-scale carbon black material produced through a specific chemical process. Acetylene black is mainly obtained by decomposing and refining acetylene with a purity of more than 99% through the calcium carbide method or by-product gas during the pyrolysis of naphtha (raw gasoline), and then undergoing continuous pyrolysis to obtain carbon black. This type of carbon black has highly unstable chemical properties and consists of two carbon atoms and two hydrogen atoms, with a chemical formula of C2H2; compared with other types of carbon black, acetylene black has more developed crystals and secondary structures, which makes it more conductive and absorbent. In addition, due to the small amount of impurities such as heavy metals, the loss caused by self-discharge is also small, making it perform well in applications such as the negative electrode of nickel-hydrogen batteries;
