多孔硅对RDX感度及性能的影响
|
摘要
为了研究纳米多孔硅对黑索今(RDX)感度和性能的影响,对其进行热性能、感度、爆速和钢凹深度的测试。结果表明:随着多孔硅的加入,RDX的撞击感度和爆速均有所降低,且随着多孔硅质量分数的增加,撞击感度依次升高而爆速依次降低;当多孔硅的质量分数为1%时,降低了RDX的摩擦感度,但多孔硅质量分数进一步增加时,却提高了RDX的摩擦感度;3%多孔硅的加入可以增加RDX的作功能力。
In order to study the effect of nano porous silicon on the sensitivity and performances of RDX,thermal performance,sensitivity,detonation velocity and concave depth of steel of RDX containing porous silicon were tested. The results show that the impact sensitivity and the detonation velocity of RDX tend to reduce with the addition of porous silicon. With the increasing content of porous silicon,the impact sensitivity turns to increase,while the detonation velocity decreases successively. When the porous silicon content is 1%,the friction sensitivity of RDX is reduced. But further increase of the porous silicon content leads to the friction sensitivity of RDX improved. The addition of 3% porous silicon contributes to the work capacity of RDX.
