摘要:
为了提高乳化震源弹的爆炸威力和抗压性能,同时减少环境污染和安全隐患,设计了一种储氢型乳化震源弹,以TiH2-玻璃微球复合敏化的乳化炸药作为起爆药柱,MgH2化学敏化的乳化炸药作为主装药。利用猛度实验、爆速实验、水下爆炸实验和冲击波动压实验,分别研究了TiH2-玻璃微球复合敏化乳化炸药的爆炸威力和MgH2化学敏化乳化炸药的爆炸威力及抗压性能。结果表明,与传统乳化震源弹相比,储氢型乳化震源弹中TiH2-玻璃微球复合敏化的乳化炸药爆炸威力大,铅柱压缩量为23.80 mm,达到军用炸药猛度,同时爆速达到4 659 m/s,适合作为起爆药柱代替TNT起爆药柱;MgH2化学敏化乳化炸药的爆炸威力大且抗压性能好,峰值压力、比冲量、冲击波总能较传统玻璃微球敏化炸药分别提高了8.7%、12.4%、33.0%,适合作为主装药代替乳化炸药主装药;采用储氢型乳化震源弹替代传统震源弹具有较好的应用前景。
Abstract:
To improve the explosion power and the pressure resistant properties of emulsifying seismic bomb, and reduce the environmental pollution and safety hazards, a kind of hydrogen storage type emulsifying seismic bomb was designed using emulsion explosive sensitized compositely by TiH2-glass microsphere as the initiating explosive grain, and emulsion explosive sensitized chemically by MgH2 as the main charge. The explosion power of TiH2-glass microsphere sensitized emulsion explosive and the explosion power and the pressure resistant properties of MgH2 sensitized emulsion explosive were studied by compression experiments, detonation velocity tests, underwater explosion experiments, and shock wave pressure experiments, respectively. The results show that compared with the traditional emulsifying seismic bomb, TiH2-glass microspheres sensitized emulsion explosive in hydrogen storage type emulsifying seismic bomb has high explosion power, the compression amount of lead column is 23.80 mm, reaching military explosives brisance and at the same time the detonation velocity is 4 659 m/s, it is suitable to be used as initiating explosive grain instead of TNT explosive grain. MgH2 sensitized emulsion explosive has high explosive power and good compressive resistance, the peak pressure, specific impulse and shock wave total energy were respectively increased by 8.7%, 12.4% and 33.0% compared with the traditional glass microsphere sensitized emulsion explosive, which is suitable for main charge instead of the main charge of emulsion explosive. The use of hydrogen storage type emulsifying seismic bomb instead of the traditional seismic bomb has a good application prospect.
