摘要
针对传统乳化炸药在使用过程中存在的压力减敏和爆炸威力低的问题,研制出化学敏化的MgH_2型储氢乳化炸药,并利用包覆MgH_2的方法有效控制了炸药的发泡过程。冲击波动压减敏实验和水下爆炸实验结果表明,与玻璃微球型乳化炸药相比,MgH_2型储氢乳化炸药的冲击波峰值压力、比冲击波能和比气泡能分别增加了20.5%、21.2%和34.7%,同时具有优异的抗动压减敏性能和储存稳定性。
Based on the pressure desensitized and low power problems that traditional emulsion explosives exists in utilization, a hydrogen storage emulsion explosives sensitized by MgH2 with chemical method was developed,and the foaming process is controlled effectively by coating MgH2 with paraffin wax film. Shock wave dynamic pressure desensitization experiments and underwater explosion experiments are implemented, and experimental results show that compared with glass microspheres type of emulsion explosives,the shock wave peak pressure,shock wave energy and bubble energy of MgHz type of hydrogen storage emulsion explosives increased 20. 5%, 21. 2% and 34. 7% respectively, and it also has a brilliant dynamic pressure resist ability and storage stability.
