Abstract: The TG-DTG, PDSC and DTA-TGA-FTIR coupling were used to an investigation of the interactions of AP with HMX and RDX The results show that there is a strong interreaction of AP with HMX and RDX during thermal decompositions HMX decomposition accelerated by AP is weakened while the AP decomposition accelerated by HMX is boosted up as pressure increases These results are interpreted by the mechanism of their decomposition

摘要： 用热重 微商热重分析 (TG DTG)、高压差示扫描量热仪PDSC和差热分析 热重分析 傅立叶红外联用技术 (DTA TGA FTIR) ,研究了高氯酸铵 (AP)与HMX和RDX的互相作用。热分析和分解气体原位实时红外跟踪分析的结果表明 ,AP与HMX和RDX之间存在着强烈的作用。提高压力使AP对HMX的加速分解作用减弱 ,而使HMX对AP分解作用增强。从它们的分解机理解释了这些结果
