摘要
为了解DADE以及含DADE的混合炸药的安全性能,用显微镜研究了DADE混合炸药降感机理。结果表明,在相同的试验条件下,DADE与TATB、NTO的机械感度相当,具有优良的安全性能;DADE粒度的大小对其感度影响很大,感度随粒度的减小而升高;在B炸药配方中,用DADE部分代替RDX后感度没有明显改变,完全代替RDX后降感效果十分明显。研究表明,DADE颗粒的合理级配以及表面包覆是降低DADE机械感度的重要途径。
To examine the safety of DADE and composite explosives with DADE, the mechanism of decreasing the sensitivity of mixed explosives with DADE is studied by means of a microscope. The result shows that under the same condition of experiment, the impact and friction sensitivity of DADE are in the same level with TATB and NTO, having very excellent safety. The particle size has important effect on DADE sensitivity. The smaller particle size makes impact and friction sensitivity increase . After replace RDX in composition B partially with DADE, the mechanical sensitivity of the formulation hardly changes, and the effect of decreasing the sensitivity is very obvious. The results show that rational particle grade and surface coating is an important process to decrease the mechanical sensitivity of DADE.
