铝粉含量对乳化炸药性能影响

Effect of Aluminum Powder Content on Performance of Emulsion Explosive

为了提高乳化炸药做功能力,实验在乳化炸药中外加铝粉,考虑到氧平衡对乳化炸药性能影响,其基础配方按正氧平衡、零氧平衡和负氧平衡设计。对每个基础配方铝粉含量分别从2%增加到14%,并在乳化炸药温度为70℃左右时加入。试验中用电测法测试了含铝乳化炸药爆速,用水下爆炸能量测试法对冲击波能和气泡能进行测试,并用盖斯三角形法计算该炸药的爆热,同时分析了铝粉含量对乳化炸药性能的影响。结果表明:随着铝粉含量的增加,乳化炸药的爆速减小,爆热、冲击波能和气泡能增加,对基础配方而言,零氧平衡时含铝乳化炸药的性能最好。

Aluminum powders with contents of 2% -14% were added into the formulation when the temperature of emulsion explosive is about 70℃. Electrical measurement was used to get the detonation velocity of emulsion explosive containing aluminum, and the underwater tests were used to obtain the shock wave energy and bubble energy of explosive. At the same time the explosion heat was calculated by GAS triangles. The effects of aluminum powder contents on performance of emulsion explosive were analyzed. The results show that detonation velocity of emulsion explosive containing aluminum decreases with the increasing of aluminum powder contents, but explosion heat, shock wave energy and bubble energy increase with the increasing of aluminum powder oontents.
