HMX炸药的重结晶超细化技术研究

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０．６２￣１．１０μｍ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

Recrystallizing Ultrafine Technology of Explosive HMX

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. 0.62～1.10μm 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.
