乳胶基质和乳化炸药受冲击波作用后的显微观察

摘要

在研究乳化炸药的压力减敏作用时,观察到程度不同的破乳现象.为深入了解此现象,分别就乳胶基质和乳化炸药在水中受到外界爆炸冲击波作用之后进行了了显微观察.发现乳胶基质和乳化炸药微观结构均遭到不同程度的破坏,局部发生了破乳,且乳胶基质的表层比内部破乳情况严重,而乳化炸药表层和内部无差别.%The deraulsification to different degree was observed when the emulsion explosive desensitiza-tion was studied. To find out this phenomenon deeply, the microscopic examination of the emulsion matrix and emulsion explosive was studied after they were subjected to the outside shockwave in water separately. The results indicated that the microstructure of the emulsion matrix and the emulsion explosive was de-stroyed to different degree by the shock wave, there was demulsification in local area, the degree of demul-sification of the surface layer of the emulsion matrix was higher than that of the inner part of the emulsion matrix, and while there was no difference between the surface layer and the inner part of the emulsion ex-plosive.
