为研究现场混装乳化炸药高温敏化工艺技术,通过实验分别研究了敏化液浓度、添加量、敏化温度及敏化助剂含量对高温敏化过程的影响,得到了最优的高温敏化工艺参数。针对高温敏化工艺对现场混装技术装备的敏化装置进行了改进,并实验研究了水环润滑剂比例与装药输送压力的关系。根据炸药性能测试及工业化应用试验,相比现场混装中低温敏化技术,高温敏化工艺技术具备显著的优势,极大提高了乳化炸药现场混装技术的安全效益和经济效益。

To study the high temperature sensitization technology of site mixing emulsion explosive,the effects of the concentration and content of sensitizing liquid,the sensitizing temperature,as well as the content of sensitizing agent on the high temperature sensitization process were studied by experiments,and the optimal parameters were obtained.The sensitization device of the site mixing equipment was improved based on the high temperature sensitization technology,and the relationship between the proportion of lubricant in water ring and the charge delivery pressure was experimentally studied.According to the detonation performance test and industrial application test of the explosive,the high temperature sensitization technology has significant advantages,which greatly improves the safety and economic benefits of the site mixing emulsion explosives,compared with the low temperature sensitization technology.
