Abstract

In order to study the inhibitory effect of Al(OH)₃ powder explosion suppressant on polyacrylonitrile (PAN) powder explosion, a transparent pipeline explosion propagation test system was used to study the influence of mass fractions of Al(OH)₃ on the flame propagation shape, temperature and other parameters of PAN powder explosion. The scanning electron microscope, thermogravimetric analyzer and Fourier infrared spectrometer were used to study the microscopic characteristics of Al(OH)₃ inhibiting PAN powder explosion, and the mechanism of Al(OH)₃ inhibiting PAN powder explosion was summarized. The results show that the maximum flame propagation distance and the velocity of PAN powder deflagration gradually decrease with the increase of the mass fraction of Al(OH)₃. At the same time, pressure monitoring and temperature monitoring showed that with the increase of the mass fraction of Al(OH)₃, the maximum explosion pressure and maximum temperature of PAN powder gradually decrease. Thus, the inhibition effect of Al(OH)₃ on PAN powder explosion was verified, and the inhibition effect of Al(OH)₃ at mass ratio of 60% was the best. Through the study of characterization and thermal analysis of PAN powder explosion solid products, the inhibition mechanism of PAN powder flame by Al(OH)₃ was analyzed from both physical and chemical aspects. Physical suppression includes coating, endothermic cooling, and gas inerting. Chemical suppression is mainly by reducing the exothermic reaction between free radicals •H, •OH and •O through consuming the key free radicals O• and OH• that maintain the chain reaction of combustion and explosion.
