The main component of carbon black is carbon, and their chemical formula is C. It is reasonable to say that it is combustible, and it is easy to burn. Why is carbon black not easy to burn? Under what circumstances can carbon black burn? Carbon What is the ignition point of black? Let me explain in detail for you.
Can carbon black burn?
First of all, it is necessary to explain that carbon black is combustible. However, carbon black is difficult to burn and requires a higher temperature to burn slowly. Generally, carbon black cannot be burned. Consider that a lot of carbon black itself is produced through incomplete combustion.
Under what circumstances does carbon black burn?
The necessary conditions for the combustion of substances are temperature and the concentration of oxygen, and the combustion temperature of carbon black is required to be between 310-400 degrees Celsius. The requirement for oxygen is also very important, because carbon black is in the form of small particles. If the same flame is heated with an open flame, the supply of oxygen will be cut off, making it difficult for carbon black to meet the combustion conditions, so it is difficult to burn.
What is the ignition point of carbon black?
There is no exact value for the ignition point of carbon black, which is related to particle size and internal structure. Usually the ignition point of carbon black is between 310~400°C.
What is the combustion form of carbon black?
The manifestations of carbon black combustion are also different. Even if the conditions for carbon black combustion are met, carbon black will generally emit light and heat slowly, become carbon dioxide (CO2) and fly away, and rarely open flames will appear directly. The resulting phenomenon led many to believe that carbon black does not burn. Secondly, we need to know that carbon black is combustible, as long as the combustion conditions are obtained, it can be burned.
