摘要:
利用小型密闭燃烧装置分别测试了两种黏结剂含量的RDX基和HMX基含铝炸药燃烧产生的准静态压力，得到4种含铝炸药燃烧能量的关系。利用气相色谱仪检测出部分气相燃烧产物的含量，通过化学计算探讨了4种含铝炸药的铝粉反应率，并用扫描电镜和能谱（EDS）对4种炸药的微观形貌和表面元素进行表征。结果表明，含铝炸药中黏结剂含量增加会使炸药与铝粉颗粒的表面包覆层变厚，更加阻碍铝粉在燃烧初期的吸热，从而在一定程度上导致铝粉反应率减小，并降低炸药燃烧总能量。
Abstract:
Small closed device for combustion was used to measure the combustion quasistatic pressures of both RDXbased and HMXbased aluminized explosives, each of which has two different binder contents. The energy relations of combustion among these four explosives were obtained. Contents of some gaseous combustion products were tested by gas chromatograph, and Al reaction ratios of the four aluminized explosives were discussed by chemical calculations. The microcosmic structure and surface elements content of these four explosives were characterized by SEM and EDS. The results show that the surface coating of explosive particles would be thicker, because of the binder content increased in aluminized explosives. The ticker surface coating would make heat absorption of Al more difficult in the prime of combustion. And then the Al reaction ratio would be decreased and the energy of combustion would be lower.
