采用 NC、NH4Cl O4、BP常用点火材料组成不同的点火剂配方 ,考察其对含 RDX的硝胺火药的点火能力。以点燃性能较好的硝化棉、单基药 (SL)作基准 ,通过点火模拟对比试验 ,获得了可提高硝胺发射药点火效能的新型点火药配方。点火剂 E(含 NC2 3.1%、BP38.5 %、NH4Cl O438.5 % )在低温 (- 4 0℃ )条件下点燃硝胺药的点火延迟时间 (tig)与制式单基药 tig相当 Using NC, NH4Cl O4, BP commonly used ignition materials composed of different ignition agent formulations to investigate its RDX nitramine gunpowder ignition ability. Based on the nitrified cotton and single base drug (SL) with good ignition performance, a new ignition powder formulation was developed through ignition simulation test to improve the ignition efficiency of nitramine propellants. Ignition agent E (NC2 3.1%, BP38.5%, NH4Cl O438.5%) ignited nitramine at low temperature (-40 ° C) and its ignition delay time (tig) was comparable to that of the standard single-base tig
