DNAN基高品质药块制备研究

Study on Preparation of High Quality DNAN-based Drug Block

为提高DNAN基熔铸炸药药块品质,以质量比DNAN/RDX/AI/AP:25/10/31/34的熔铸炸药为研究对象,采用2种不同制备工艺进行对比试验,并对药块的内外部疵病、药块密度及其分布均匀性进行分析。结果表明,与常规药块制备工艺相比,采用改进工艺技术制备的药块,制备产能提升了5倍,工艺安全性得到了改进,药块疵病大幅减少,药块密度分布均匀性得到明显改善。

In order to improve the quality of DNAN-based melt-cast explosive,the melt-cast explosive with the mass ratio of DNAN/RDX/AI/AP:25/10/31/34 was taken as the research object.2 different preparation processes were used to carry out comparative tests,and the internal and external defects,density and distribution uniformity of the melt-cast explosive were analyzed.The results showed that compared with the conventional technology,the production capacity of the improved technology was increased by 5 times,the process safety was improved,the defects of the block were greatly reduced,and the density distribution uniformity of the block was obviously improved.
