含废弃丁羟推进剂的凝胶炸药

为安全处理和再利用废弃固体推进剂,通过添加单基药将丁羟推进剂再利用制备了灌注式凝胶炸药.采用验证板试验及电离探针法研究了不同装药配比、推进剂颗粒尺寸及装药直径对炸药爆轰性能的影响.结果表明,丁羟推进剂难以发生爆轰,若添加适量单基药,能显著提高炸药的爆轰感度,并降低其临界直径；该凝胶炸药密度为1.6 g/cm3,直径为7...

Gel Explosive Containing Waste HTPB Propellants

In order to dispose and reuse waste solid propellants safely,a type of gel explosive containing waste HTPB propellant and single-base propellant was proposed.The effects of charge ratio between the single-base propellants and HTPB propellants,particle size of HTPB propellant and charge diameter on the detonation properties of the gel explosive were studied by the witness plate test and ionization probes.The results show that the HTPB propellant itself is hard to detonate,but if some single-base propellants are added and mixed with HTPB propellant in the charge,the impact sensitivity of explosive can be significantly improved,the critical diameter would also be reduced.The density of the gel explosive is about 1.6 g/cm3,and the detonation velocity is more than 6 500 m/s when the charge diameter is 70 mm.Thus it can be used as an open-air commercial gel explosive with big charge diameter.
