摘要
改善 HMX炸药的重结晶细化效果 .通过制备 HMX超微粉体炸药的研究 ,提出一种化学重结晶与物理作用相结合的喷射细化方法 .其核心技术在于炸药溶液与非溶剂的混合方式采取了喷射分散混合 ,强烈搅拌混合的射流使炸药颗粒以极快的速度沉淀 ,并产生超细粒度 .得到了 0 .6 2～ 1.10 μm的 HMX超细炸药 .叙述了该方法的理论基础并探讨了喷射细化机理 .采用喷射细化方法能明显改善 HMX炸药的重结晶细化效果 ,其细化产品粒度分布范围窄 。
To improve the recrystallizing fine effect of explosive HMX, a novel method——the spray fine method which combines chemical action with physical action——was presented. Jet dispersing was used in the mixed process of HMX solution and non solvent and ultrafine particles were precipitated at a rapid velocity. 0 62～1 10 μm particle of explosive HMX were prepared and the theoretical basis of the method and the mechanism of the spray fine process were elucidated. The recrystallizing fine effect of explosive HMX can be distinctly improved by using the spray fine method and a narrow range of particle size distribution of explosive HMX can be obtained.
