摘要/Abstract

摘要： 利用热分析—质谱和红外联用法、高压差示扫描量热法研究了高氯酸铵(AP)粒度对AP-CMDB推进剂在0.1 MPa(常压)和1.0MPa压强下的热分解过程。结果表明,含不同粒度AP的AP-CMDB推进剂的热分解过程存在明显的差异,含大粒度AP(d50=96.8μm)的推进剂在常压和1.0 MPa下的热分解过程均出现了AP单体的高温分解阶段,含小粒度AP(d50=12.4,8.5和1.0μm)的推进剂在高压下均仅表现出一个快速分解阶段;AP-CMDB推进剂分解过程中的气体产物主要包括NO2,NO,N2O,CO2,CO,O2,N2,H2O,HCHO和HCl。

Abstract: The effects of the granularity of Ammonium Perchlorate(AP) on the thermal decomposition of AP-CMDB propellant were experimentally studied by the combination technique of thermal analysis,MS and rapid-scan Fourier transform infrared spectroscopy(Thermal analysis-MS-FTIR) and the pressure differential scanning calorimetry(PDSC).The results show that there are obvious differences in the thermal decomposition of AP-CMDB propellant with AP of different granularities.The decomposition gas products of AP-CMDB propellant consist of NO2,NO,N2O,CO2,CO,O2,N2,H2O,HCHO and HCl.
