糠蜡在乳化炸药中的应用*
The Application of Bran Wax in Emulsion Explosive
摘要：
选用糠蜡与石油副产物制备复合油相。用Span80、T152与油胺配比为4瞷1瞷1的复合乳化剂和复合油相按配方制备乳化炸药。测试结果显示，乳胶基质黏度比较高，且50℃时的黏度小于25℃时的黏度。经过13次高低温循环后，乳胶基质电导率变化较小。在转速8000r/min时离心，乳胶基质破乳程度相对弱。 SEM图显示乳胶基质粒子分布相对均匀，大部分粒子粒径在1μm左右。 DSC实验分析得分解温度在270～280℃之间，相对较高。乳化炸药爆速、猛度都比较高，距离为3 cm的殉爆测试，能保证100％爆轰。
Abstract：?
Bran wax was selected to prepare composite oil phase with petroleum byproducts .Thereby, emulsion ex-plosive was prepared by using the emulsifier with the ratio of Span 80, T152 and oil amine 4:1:1 and composite oil phase according to the recipe .The test results show that the viscosity of the emulsion matrix is relatively high and the viscosity at 50℃is less than that at 25℃.The variation of the conductivity of emulsion matrix is minor after temperature alters high and low for 13 times.The demulsification of emulsion matrix is relatively weak when centrifugal speed is 8000r/min.SEM images show that the distribution of emulsion matrix particles is relatively uniform , and most of the particle diameter is a-bout 1μm.Experimental analysis of DSC shows that the decomposition temperature is relatively high , between 270℃to 280℃.The detonation velocity and brisance of emulsion explosive are relatively high , and the sympathetic detonation test at a distance of 3cm can ensure 100%detonation.
