“层内爆炸”技术用硝基甲烷改性液体炸药的配方研究
Explosive Materials(2015)
Abstract
根据“层内爆炸”技术对液体炸药理化性能、安全性能和爆轰性能的要求,采用单因素法对硝基甲烷液体炸药进行改性研究,确定硝基甲烷改性液体炸药配方的质量分数为:硝基甲烷76%、乙二胺5%、醋酸纤维素5%、片状铝粉14%.该配方硝基甲烷改性液体炸药的主要性能指标为:黏度1 342 mPa·s,pH值8.0,挥发率2.0%,机械感度0,临界传爆直径2.5~3.0 mm,爆容662 L/kg,爆热5 749kJ/kg,爆速4 233 m/s,满足“层内爆炸”技术开采低渗透油气藏的使用要求.
