油相材料对混装乳化炸药性能的影响

Influence of oil phase materials on properties of mixed emulsion explosive

为了研究油相材料对混装乳化炸药性能的影响,在常规现场混装乳化炸药配方的基础上,通过改变油相材料种类,对油相材料黏度、乳化基质黏度、乳化基质敏化效果及对应装药爆速等性能参数进行测定,研究不同黏度油相材料、机油和柴油复配比例对现场混装乳化炸药黏度、敏化效果以及爆轰性能的影响。结果表明,随着机油标号及油品黏度的增大,乳化基质的黏度在低温、高温状态下均升高,基质在高温敏化时固泡能力逐渐增强,表观敏化气泡更加细腻,爆轰性能更优;随着柴油添加比例的增大,机油和柴油复配的基质黏度逐渐降低,70℃下乳化基质黏度调控范围在13900~35340 cp;研究结果能够较好地指导现场混装乳化炸药配方设计及性能调配。

In order to study the influence of oil phase materials on the properties of mixed emulsion explosives,at the scene of the conventional,on the basis of mixed loading emulsion explosive formulations,by changing the oil phase material types,to the oil phase material viscosity and viscosity of emulsion matrix,the effects of sensitized emulsion matrix and corresponding charge detonation velocity measurement of performance parameters such as,different viscosity,oil and diesel oil phase material ratio on the viscosity of the mixed loading emulsion explosive,sensitization effect and the influence of detonation performance.The results show that with the increase of engine oil grade and oil viscosity,the viscosity of the emulsified matrix increases at both low and high temperatures;with the increase of the viscosity of the oil phase material,the foaming ability of the matrix gradually increases during high temperature sensitization.Enhanced,the apparent sensitization bubbles are more delicate,and the detonation performance is better;with the increase of the proportion of diesel fuel,the matrix viscosity of the engine oil and diesel fuel will gradually decrease,and the viscosity control range at 70°C is 13900~35340 cp;the research results can Better guidance for the formulation design and performance allocation of mixed emulsion explosives.
