Carbn black CAS 1333-86-4 , also known as carbon black, is an amorphous carbon. A light, loose, and extremely fine black powder with a very large surface area ranging from 10 to 3000m2/g. It is a product of incomplete combustion or thermal decomposition of carbon containing substances (coal, natural gas, heavy oil, fuel oil, etc.) under insufficient air conditions. Specific gravity 1.8-2.1. Gas black is made from natural gas, lamp black is made from oil, and acetylene black is made from acetylene. In addition, there are “slot black” and “furnace black”. According to the performance of carbon black, there are “reinforced carbon black”, “conductive carbon black”, “wear-resistant carbon black”, etc. It can be used as a black dye for manufacturing Chinese ink, ink, paint, and also as a reinforcing agent for rubber.

Application

Carbon black is usually divided into pigment carbon black, rubber carbon black, conductive carbon black, and specialized carbon black according to its purpose.

Carbon black for pigments – internationally, according to the coloring ability of carbon black, it is usually divided into three categories, namely high pigment carbon black, medium pigment carbon black, and low pigment carbon black. This classification is usually represented by three English letters, with the first two letters indicating the coloring ability of carbon black and the last letter indicating the production method.

Carbon black for rubber – Carbon black for rubber was originally classified based on particle size, but later changed to nitrogen surface area classification. In addition, the naming also takes into account factors such as the vulcanization rate and structure of carbon black pigments, consisting of four systems. The first English letter represents the curing rate of the rubber compound, with N representing the normal curing rate and S representing the slow curing rate. The last three are Arabic numerals. The first number represents the range of carbon black nitrogen surface area, which is divided into 0-9 levels. The second and third numbers are designated by Committee D24.41 of the American Society for Testing and Materials responsible for carbon black and terminology, reflecting different degrees of structure, which is determined by the approximate high and low structure of carbon black, with a certain degree of arbitrariness. Relatively speaking, the larger the number, the higher the structure.
