DNAN基高品质药块制备研究

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。

Study on Preparation of High Quality DNAN-based Drug Block

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.
