摘　　要：文章通过测定乳化基质和乳化炸药的电导率、NH4NO3的析出量及溶失率,分析对比了不同受压距离对其稳定性的影响。根据界面溶胀理论,提出乳化炸药的界面膜与其稳定性的关系,揭示了乳化炸药敏化前抗压强度优于敏化后。该文的研究工作对解决乳化炸药用于毫秒延时爆破作业时,遇到的炮孔装药不完全爆炸或拒爆问题具有重要意义。Analysis and comparison is made about the impact of different pressure distance on its stability in this paper,by measuring the conductivity,NH_4NO_3 precipitation amount and solubility of emulsion matrix and emulsion explosive.Based on swelling interface theory,the relationship of the interfacial film and the stability is propounded,and the compressive strength of emulsion explosive before the sensitization is revealed to be superior to that of after sensitization.Studies in this paper will be very important for solving the problem of incomplete blasting or misfire when emulsion explosive used in millisecond delay blasting.
