高温老化对HMX基炸药爆速的影响

为掌握高温老化对HMX基炸药爆速影响的规律,选择粘合剂不同的两种HMX基炸药进行高温老化试验。通过测量药柱尺寸,计算炸药的密度,采用电雷管起爆测试方法获得了试样的爆速。结果表明:高温老化时间对炸药的密度影响不同,老化8天是两种炸药密度变化的分界点,超过8天,试样的密度发生较大变化;两种炸药的爆速随老化时间下降显著,但H-2炸药的爆速始终高于H-1炸药。

Effect of High Temperature Aging on the Detonation Velocity of HMX-based Explosives

In order to understand the decay rate of HMX-based explosives before and after aging, two kinds of HMX-based explosives with different binders were selected for aging test. The density of explosives was obtained by calculation, and the detonation velocity of the samples was obtained by electric detonator detonation test method. The results show that the aging time has different effects on the density of explosives. The aging of 8 days is the boundary point between the density changes of two kinds of explosives. The density of the samples changes greatly over 8 days; the detonation speed of the two explosives decreases significantly with the aging time, but The explosive rate of H-2 explosives is always higher than that of H-1 explosives.
