一种低爆速爆炸焊接炸药的实验研究

摘要

In order to meet the requirement of metal explosive welding on the detonation velocity, a low detonation velocity explosive for explosion welding was made which used the expanded ammonium nitrate as main ingredient and the diluent M as additive. The experiment results show that the explosive has stable detonation and moderate energy, and when the content of diluent M is 25%the detonation velocity is 2045 m/s which is suitable for explosive welding.%为满足金属爆炸焊接对爆速的要求，本研究以膨化硝铵炸药为主体，通过添加适量的稀释剂M制得低爆速爆炸焊接炸药。实验结果表明，该炸药具有爆轰稳定，能量适中等特点，当稀释剂含量为25%时，爆速在2045m∙s-1，适用于爆炸焊接应用场合。
