亚微米炸药的感度选择性

Selectivity of the sensitivity of the sub-micron explosive

采用亚微米粉体炸药 (0 .1～ 1 μm )与普通粉体炸药 (>1 0 μm )进行了落锤撞击感度和冲击片 (高压短脉冲 )起爆感度对比试验 ,发现亚微米粉体炸药有在常见环境力 (一般的撞击、摩擦 )条件下比较安全 ,而在特定激励 (冲击片 )作用下起爆可靠性提高的感度选择性特点 ,并从理论上对上述特性进行了探讨。研究表明 ,亚微米粉体炸药具有非常好的应用前景。

The contrast test of the sensitivity between coarse size and sub micron size was done by both drop hammer tester and slapper initiating tester. The result shows that the sub micron explosive is safe when it is motivated by a generic environmental force, such as impact force and friction force. And the reliability is improved when it is motivated by special environmental force, such as slapper, which is the selectivity of sensitivity of sub micron explosive. In addition, the mechanism is discussed in theory. The sub micron explosive has great foreground for application.
