| 摘 要： | 为降低岩石粉状乳化炸药的爆速,选择了一种HW矿物粉,通过筛混方式将该分散剂与炸药混合,并测定了该分散剂加入量和布药厚度对炸药爆速的影响。结果表明,岩石粉状乳化炸药中掺入44.5%50%的HW矿物粉时,爆速为1913m/s50%的HW矿物粉时,爆速为1913m/s2378m/s,经钢与不锈钢板爆炸焊接试验表明,爆炸结合率达100%,可满足金属爆炸焊接用炸药的要求。

| Abstract: | A kind of HW mineral powder was chosen as dispersant to reduce the rock powdery emulsion explosive detonation velocity,and it was screened and mixed into explosive.The influence of the dispersant addition and charging thickness on detonation velocity were also measured.The results showed that when the addition of HW mineral powder was between 44.5%and50% and the detonation speed was 1913m/s2378m/s,经钢与不锈钢板爆炸焊接试验表明,爆炸结合率达100%,可满足金属爆炸焊接用炸药的要求。A kind of HW mineral powder was chosen as dispersant to reduce the rock powdery emulsion explosive detonation velocity,and it was screened and mixed into explosive.The influence of the dispersant addition and charging thickness on detonation velocity were also measured.The results showed that when the addition of HW mineral powder was between 44.5%and50% and the detonation speed was 1913m/s2378m/s.The explosive welding experiments of steel and stainless steel plate showed that binding ratio was up to 100%,and it could satisfy the requirements for explosive used in explosive welding. |
