摘要
传统乳化炸药在低温下由于乳胶基质中氧化物溶解度降低、水相凝固、有机相变硬等原因,存在破乳析晶、结冻等现象,致使其爆炸性能降低,不能完全爆轰,甚至拒爆,影响高纬度地区低温条件下的工程爆破作业效果。综合近年来国内外对耐低温乳化炸药的研究,对乳化剂类型、油相材料、氧化剂水溶液的析晶点、敏化方式等影响乳化炸药耐低温性能的主要因素分别进行了概述及分析,综述了耐低温乳化炸药的研究进展。
Freezing and crystallization of traditional emulsion explosives can be obseryed due to the decreased solu-bility of oxidant in emulsion matrix,water coagulation and organic phase hardenings at low temperature. Those phenomena mentioned above may cause decreased explosive performances,incomplete detonation or even failure,which are in appro-priate to the engineering blasting at high latitude areas with low temperature. Comprehensive studies were carried out on the low temperature-resistance emulsion explosives in recent years. The main raw material factors on the storage stability of emulsion explosives at low temperature, such as the type of emulsifier, oil phase materials, crystallization of oxidants solu- tion,sensitization method,were analyzed. The research progress of low temperature-resistant emulsion explosives was also summarized.
