Factors Influencing the Self - ignition and Combustion Process of Carbon Black

摘要

This paper investigates the influence of main factors determining the trend of self- ignition of carbon black. Experimental determinations were performed on samples of carbon black in different areas of the manufacturing process, working under different conditions, in order to highlight the determinants for the initiation of combustion. Combustion research has been conducted under static conditions using thermogravimetric and termodifferential analysis equipment. The results showed the influence of natural samples, heating rate, the oxygen content of the environment and thermal loading of area on the self -ignition temperature. Findings are particularly relevant to carrying out the parameters of conditioning and avoiding reaching completion conditions of self- ignition. They are crucial to analyse root causes for different fires.
