摘要:
乳化炸药；损伤；静空气压力；静水压力；机械摩擦；对化学敏化、珍珠岩敏化、玻璃微球敏化的3种乳化炸药进行静空气压力、静水压力和机械摩擦模拟损伤试验研究。在0.6MPa静空气压力作用下，3种乳化炸药的作功能力分别下降了1.89%、3.92%、1.64%，爆速分别下降4.72%、4.84%、3.15%；在0.6MPa静水压力作用下，3种乳化炸药的作功能力分别下降了21.05%、27.57%、23.16%，爆速分别下降11.16%、14.36%、12.15%；在机械摩擦作用15min后，作功能力分别下降了1.12%、4.97%、3.74%，爆速分别下降1.87%、7.56%、6.91%。结果表明，在静空气压力及机械摩擦作用下，3种乳化炸药爆炸性能衰减较小，作功能力衰减幅度小于爆速；在静水压力作用下，3种乳化炸药爆炸性能衰减较大，作功能力衰减幅度大于爆速。爆炸性能
Abstract:
The experimental research by means of static air pressure, hydrostatic pressure and mechanical friction was conducted on the damage simulation of three types of emulsion explosives sensitized by chemical, perlite and glass microballon sensitization, respectively. Under the static air pressure of 0.6MPa, the power of three types emulsion explosives reduced by 1.89%, 3.92% and 1.64%, respectively, and the detonation velocity reduced by 4.72%, 4.84% and 3.15%, respectively. Under the hydrostatic pressure of 0.6MPa, the power of three types emulsion explosives reduced by 21.05%, 27.57% and 23.16%, respectively, and the detonation velocity reduced by 11.16%, 14.36% and 12.15%, respectively. After mechanical friction of 15min, the power of three types emulsion explosives reduced by 1.12%, 4.97% and 3.74%, respectively, and the detonation velocity reduced by 1.87%, 7.56% and 6.91%, respectively. Results showed that, under static pressure and mechanical friction, the loss of detonation property of three types emulsion explosive was small, and the loss of power was less than that of detonation velocity; and under hydrostatic pressure, the loss of detonation property of three types emulsion explosive was large, and the loss of power was more than that of detonation velocity.
