摘要
采用物理气相沉积(PVD)技术研制了钝化太安炸药薄膜,对薄膜的微观结构和颗粒粒度进行了分析,对颗粒粒度与薄膜爆轰波稳定传播临界尺寸的关系进行了探索。结果发现颗粒粒度影响着薄膜的性质,构成炸药薄膜的颗粒粒度由微米级转化为纳米级将会缩小炸药薄膜的临界尺寸,有利于爆炸元件的微小型化。提出了含能薄膜材料向纳米化发展的方向。
The desensitized explosive PETN film was prepared by physical vapour deposition (PVD) technology,and SEM was used to analyze the mierostrueture and grain size of PETN film. The relationship between grain size of film and the critical dimension of detonation wave propagation was discussed. The results show that the grain size affects the properties of explosive film, and the de- crease of grain size in explosive film helps to decrease critical dimension of detonation wave propagation and mierominiaturize explosion element.
