摘要
通过测试水中爆炸冲击波,将乳化炸药压力减敏作用数量化,用减敏程度来表征,定量地比较和分析炸药的抗压性能.采用该方法研究了Span80含量与乳化炸药压力减敏作用之间的关系.结果表明,乳化剂含量对乳化炸药的压力减敏作用有较大影响,随着Span80含量的增加,乳化炸药发生压力减敏作用的程度减小,其含量为4%时,减敏程度最小,亦即抗压性能最好,乳化剂含量继续增加炸药的抗压性能下降.
Desensitization of emulsion explosives was quantified by means of measuring its explosion shock waves in water, and a concept of desensitization degree was used to express the extent of desensitization which could compare and analyze the anti pressing performance of explosives quantitatively. The relationship of Span-80 content to pressure desensitization of emulsion explosives was studied with the method. Emulsifier content showed strong influence on pressure desensitization of emulsion explosives and desensitization degree decreased with the increase of Span-80 content. While the Span-80 content reached 4%, the desensitization degree became the least. The anti-pressing performance of the explosive was the best, but the anti-pressing performance would decrease if the Span-80 content further increased.
