摘 要:塑料粘结炸药(PBX)的机械撞击感度远低于单纯炸药,这因为塑料包覆层改进了炸药晶体表面性质。本工作研究了含有燃烧向爆炸转变(DDT)抑制剂-三苯甲醇(TPC)对于黑索今(RDX)的机械感度影响,发现含TPC的RDX撞击感度低于不含TPC的。塑料粘结剂改进,并降低在撞击时热点产生的概率(P_4),而TPC则降低热点传播的概率(P_2)。可以预期含有TPC类型化合物的PBX机械感度可能会大幅度地降低。The impact sensitivity of plastic-bonded explosives (PBX) is significantly smaller than that of without plastic, because plastic may improve the surface property of explosive crystal. In this paper the influence of DDT (Deflagration Detonation Transition) preventing agent-triphenylcarbinal (TPC) upon the impact sensitivity of cyclotrimethylenetrinitroa mine (RDX) is studied. It has been found that the impact sensitivity of PBX-RDX with TPC is quite smaller than that of without it.TPC improves and decreases the probability of growth and propagation of the hot spots. It may he expected that the impact sensitivity will be decreased significantly for the PBX with DDT preventing agent as well as triphenyl compounds.
