树脂微球敏化乳化炸药的安全性研究

摘要

Safety analysis of an emulsion explosive sensitized by resin microspheres with various features of enclosed micropores,smooth surface and high compressive strength was conducted in comparison with those fabricated by current sensitization technology.Its friction sensitivity,impact sensitivity, thermal sensitivity, thermal decomposition temperature and vacuum stability,compatibility of emulsion matrix to resin microsphere and emulsion explosive safety were studied both at room temperature(20℃)and at high temperature(95℃).Results show that resin microsphere could improve intrinsic safety,blasting performance and storage stability of emulsion explosive.Emulsion explosive sensitized by resin microsphere has mechanical insensitivity,good thermal safety and chemical stability.Resin microsphere could be applied in sensitiza-tion either at high temperature or middle/low temperature on the production line of emulsion explosive.%介绍了乳化炸药敏化技术的安全性现状,对比分析了具有封闭微孔、表面光滑、耐压强度高的树脂微球作为敏化剂的乳化炸药的安全性,并对树脂微球敏化的乳化炸药在常温(20℃)及高温(95℃)时的摩擦感度、撞击感度、热感度、热分解温度、真空安定性及乳胶基质同树脂微球的相容性进行检测.结果表明:树脂微球提高了乳化炸药的本质安全性及产品的爆炸性能和储存稳定性;树脂微球敏化的乳化炸药机械感度低,具有良好的热安全性及化学安定性.该敏化技术对高温敏化及中低温敏化乳化炸药生产线均适用.
