| 摘 要： | 为了研究敏化方式对MgH_2型储氢乳化炸药爆轰性能的影响,进行了两种储氢乳化炸药的水下爆炸和猛度测试实验。借助实验数据和理论分析,研究了MgH_2型储氢乳化炸药作功能力与猛度之间的关系,并对用比冲量表示炸药猛度的理论进行了修正。结果表明,在物理敏化和化学敏化的MgH_2型储氢乳化炸药中,MgH_2粉末分别起到含能添加剂和化学发泡剂的作用。与化学敏化相比,物理敏化的MgH_2型储氢乳化炸药比冲击波能、比气泡能和总能量分别下降了11.98%、5.38%和8.66%,但其猛度(铅柱压缩量)却提高了5.15 mm,说明敏化方式对MgH_2型储氢乳化炸药的作功能力和猛度具有显著影响。

| Abstract: | To study the effect of sensitizing methods on the detonation performances of MgH2-based hydrogen storage emulsion explosives, the underwater explosion and brisance testing experiments of two kinds of hydrogen storage emulsion explosives were carried out. With the help of experimental data and theoretical analysis, the relationships between the work capability and brisance of MgH2-based hydrogen storage emulsion explosives were studied and the theory of using the specific impulse to express the brisance of explosive was adjusted. The results show that in the physical and chemical sensitization of MgH2-based hydrogen storage emulsion explosives, MgH2 powders play the roles of energetic additive and chemical foaming agents, respectively. Compared with the chemical sensitization, the specific shock wave energy, specific bubble energy and total energy of the physical sensitization of MgH2-based hydrogen storage emulsion explosives are decreased by 11.98%, 5.38% and 8.66%, respectively, but its brisance (lead block compression value) is increased by 5.15 mm, which means that sensitizing methods have significant impact on the work capability and brisance of MgH2-based hydrogen storage emulsion explosives. |
