报废固体推进剂的降感技术

为了清理火箭发动机内报废的推进剂,采用萃取法对含能组分进行降感处理,研究了萃取剂质量浓度对萃取效果及含能组分溶解度的影响,最后对萃取液中含能组分采用蒸馏方法进行回收。结果表明,从报废复合固体推进剂中萃取出AP后,推进剂的撞击感度、摩擦感度降低60%,推进剂本体发生裂解、失强,有利于发动机内报废推进剂的安全销毁,优选出最优萃取剂为T J-3,AP组分的回收利用使推进剂中大量氧化剂得以回收,有利于环保。

Depressing Sensitivity Technique of the Waste Composite Solid Propellants

To dispose waste composite solid propellants in solid rocket,the treatment of depressing the shock sensitivity and friction sensitivity of the propellant is performed by the method of extracting energetic component,AP in the propellant.The effect of mass concentration of extract on the extration efficiency and dissolubility of energetic component,the rate of depressing sensitivity and method of recovering energetic component from extraction solution with distillation method are studied.The results show that the shock sensitivity and friction sensitivity of the propellants after the extraction of AP from waste propellants descend 60%.The crack and pressure loss of propellant is favourable for the safety destruction of waste composite solid propellants in solid rocket.TJ-3,as an optimum extractant is studied.The recovery of AP from the propellant is beneficial to environment protection.
