摘要:
为了提高熔铸炸药块铸装药质量，以质量比DNAN/RDX/Al:55/20/25的基础配方为研究载体，采用两种不同装药工艺进行装药对比试验，并对样品的内外部质量、装药密度及其均匀性进行分析。结果表明，与常规块铸工艺相比，采用预整形同步块铸技术所装填的药柱，其装药密度达到了1.726 g/cm3，相对密度为95.8%，与常规块铸工艺相比分别提高了0.041 g/cm3和2.2%；同时减少了装药的缺陷，使装药内外部质量获得提高，并改善了装药的密度及其均匀性。
Abstract:
To improve the blockmolded charge quality of melt-cast explosives, the comparable experiments of charge were carried out by two kinds of processes based on the formulation of DNAN/RDX/Al=55/20/25 (mass ratio) as a research object. Moreover, the inner and outer quality, charge density and homogeneity of the samples were analyzed to validate the advantage of the new method. The outcomes show that, compared with conventional blockmolded casting, the density of charge due to preshaping and synchronous blockmolded casting reaches up to 1.726 g/cm3, and the relative density is 95.8%, which increase by 0.041 g/cm3 and 2.2%. Furthermore, the drawbacks of charge declined, the inner and outer charge quality was advanced, and the uniformity of charge density was improved.
