用T154、T155和Span80制备复合乳化剂,采用DSC—TG联用技术研究了用复合乳化剂制备的4种乳化炸药的热分解行为,用Kissinger法、Ozawa法及Satava—Sesták法计算其热分解动力学参数。通过3种方法结果的比较得到4种乳化炸药热分解反应的动力学参数和最概然机理函数。
Multiple emulsifier was prepared by T154,T155 and Span80. The thermal decomposition behaviors of four kinds of emulsion explosives prepared by multiple emulsifier agents were studied by DSC-TG technique. The thermal decomposition kinetic parameters of these emulsion explosives were calculated by Kissinger,Ozawa and Satava-Sesták methods. Their thermal decomposition kinetic parameters and the most probable mechanism function were obtained by comparison of calculated results by three methods.
