Is carbon black dangerous? What is the ignition point?
May 18, 2022
Carbon black is not classified as a dangerous product; there is no exact value for the ignition point, it is related to particle size and internal structure. Usually the ignition point of carbon black is between 310 and 400°C.
Carbon black generally refers to simple carbon particles. Generally, due to insufficient combustion of organic matter, the hydrogen and oxygen elements in it are converted into water, and the carbon element is not fully burned, and it will be separated from the molecules to form carbon black.
Carbon black is composed of carbon, but is generally classified as an inorganic pigment. Carbon black is a black powdery substance formed by incomplete combustion or thermal cracking of hydrocarbons in the gas phase. Due to different production processes, various products with different properties can be obtained through different process conditions.
What is the form of carbon black combustion?
The manifestations of carbon black combustion are also different. Even if the conditions for carbon black combustion are reached, carbon black will generally emit light and heat slowly, turn into carbon dioxide (CO2) and fly away, and there will rarely be an open flame directly. The resulting phenomenon has led many to believe that carbon black does not burn. Secondly, we need to know that carbon black can be burned, as long as the combustion conditions are obtained, it can be burned.
