摘要
利用燃速和火焰结构测试、TG-DTG和高压DSC实验分别研究了含1,3,3-三硝基氮杂环丁烷(TNAZ)的两类(TZ-CMDB和TZ-NEPE)推进剂的燃烧性能和热行为,发现了TNAZ对推进剂燃速、压力指数和火焰结构的影响及高压下TNAZ对上述两类推进剂中其它含能组分分解的影响,并得出常压下TZ-CMDB和TZ-NEPE推进剂受热时,TNAZ挥发和分解的温度范围为58～190℃。
The combustion characteristics of two types of propellants (TZ-CMDB and TZ-NEPE propellants) containing 1,3,3-trinitroazetidine (TNAZ) were studied by the determination of burning rate and analysis of flame structure, and the thermal behavior of TZ-CMDB and TZ-NEPE propellants were studied by TG-DTG and high pressure DSC. The effects of TNAZ on the combustion characteristics of the propellants and on the decomposition of other components in the propellants were described. The results show that the volatilization, sublimation or decomposition of TNAZ occur in the first mass-loss step on TG curve .With increasing the content of TNAZ in the propellants,the burning rate and pressure exponent of the propellants had little change and the flame of the propellants became less luminous. The decomposition of TNAZ was remitted to the second step on DSC curve where TNAZ decomposed together with RDX.
