摘要
为考察螺旋压伸工艺成型的RDX-CMDB推进剂的危险性,进行了摩擦感度、撞击感度、雷管感度、隔板、燃烧转爆轰、跌落、热安定性、爆发点、慢速烤燃和静电感度等典型试验。结果表明,该推进剂从10 m高度自由跌落不燃烧,慢速烤燃在164.2℃发生燃烧反应,在18 mm厚有机玻璃隔板下,仍能被冲击波引爆,摩擦感度(P)为2%,撞击感度特性落高(H50)为26.3 cm,50%发火时的静电点火能量为208.46 mJ,结果表明,该推进剂热安定性良好,对机械刺激不敏感,对冲击波刺激较敏感,该推进剂的危险等级为1.1级。
In order to explore the hazard property of the RDX-CMDB propellant prepared by screw-extrusion technique,typical experiments including friction sensitivity,impact sensitivity,detonator sensitivity,gap,deflagration-to-detonation transition（DDT）,drop,thermal stability,explosion temperature,slow cook-off,and electrostatic sensitivity were carried out.Results show that the propellant does not combust dropping freely from 10 m height,combusts under 164.2 ℃ during slow cook-off test,and detonats under 18 mm-thick organic glass by the shock-wave,and the friction sensitivity and 50% drop height of impact sensitivity was 2% and 26.3 cm,respectively,and the 50% ignition energy by electrostatic spark is 208.46 mJ,which indicating that the propellant has fair thermal stability,is insensitive to the mechanical stimulation,and is sensitive to shock-wave stimulation.The hazard rating of the propellant is 1.1.
