摘要
利用水下爆炸测试系统,对乳化基质和玻璃微球敏化的乳化炸药分别施加动态压力,并对受压前后的乳化基质和乳化炸药的电导率进行了测定,用电导率的变化来表征破乳程度。实验结果表明,乳化基质受压后电导率变化较小,而乳化炸药的电导率变化较大。因此,乳化基质的抗动压性能优于乳化炸药。
Using underwater explosion test system, dynamic pressure was carried on emulsion matrix and emulsion explosives sensitized by glass micro-balloon （GMB） respectively, and the electrical conductivity pressed fore and aft were measured, which was denoted demulsification degree. Experimental results show that the electrical conductivity of emulsion matrix changes a little, but that of the emulsion explosive changes greatly. So the dynamic pressure resistance ability of emulsion matrix is better than emulsion explosive.
