RDX和铝含量对RDX基含铝炸药热爆发温度的影响

通过热爆发延滞期试验测定了含铝炸药的5s延滞期热爆发温度Tb,研究了RDX和铝粉含量对热爆发温度的影响.结果表明,随着RDX含量的增加,Tb先下降后升高,获得了描述Tb与RDX和铝粉含量关系的线性经验方程.认为在热爆发试验中体系是从含能材料热分解和加热介质两个途径获得能量(热量),前者与含能反应物的含量有关,后者与体系...

Effect of RDX and Al Contents on the Heat Explosion Temperature for RDX-based Aluminized Explosives

The explosion temperatures Tb of 5 s delay for aluminized explosives of different RDX contents were determined by heat explosion test,and the effects of RDX and aluminum powder contents on explosion temperatures were studied.The results show that the Tb values first fall down and then rise with the increasing of RDX contents.A linear empiric equation,in which Tb is correlated with RDX and aluminum powder contents,was obtained.It is considered that the energies necessary to heat explosion under the test cond...
