含退役双基发射药的低爆速炸药的研究❋

摘要

[ ABSTRACT] A low detonation velocity explosive containing double-base propellant was developed by mixing the double-base propellant as a sensitizer with ammonium nitrate as an oxidant. The explosive contains ( mass fraction) 75%-80%ammonium nitrate, 15%-22% double-base propellant, 1%-5% density modifier and 1%-3% process additives. Testing results show that a series of low detonation velocity explosives could be produced to meet with various product requirements by changing the mass fraction of double-base propellant. Production control can be well realized within a density range of 0. 76-1. 02 g/cm3 , a detonation velocity range of 1500-2200 m/s, a brisance range of 8. 8-9. 7 mm, and a sympathetic detonation distance up to 4 cm. The influence on detonation velocity was analyzed and discussed due to the variations in content, granularity, density and diameter of double-base propellants.%研究了一种含双基发射药的低爆速炸药。这种炸药以双基发射药作为敏化剂，以硝酸铵作为氧化剂，二者混合后形成低爆速炸药。炸药由质量分数为75%~80%的硝酸铵、15%~22%的双基发射药、1%~5%的密度调节剂和1%~3%的工艺添加剂组成。试验表明，在低爆速炸药中，随双基发射药质量分数的不同，可制备出满足不同需求的低爆速炸药产品。产品密度控制在0.76~1.02 g/cm3之间，爆速在1500~2200 m/s之间，猛度在8.8~9.7 mm之间，殉爆距离达到4 cm。分析探讨了双基发射药的含量、粒度、密度、直径等对爆速的影响。
