摘要
为了探索硝胺类炸药的粒度对其烤燃热感度的影响,采用喷射细化法和滴加法,分别制备了三种粒度(亚微米、微米、数十微米)的黑索今(RDX)、奥克托今(HMX)、太安(PETN)粉末。采用扫描电子显微镜(SEM)和激光粒度分析仪对样品进行了表征,并按照GJB772A-1997方法608.1在自制的慢烤装置中对其进行了烤燃(cook-off)试验。结果表明,随着RDX、HMX、PETN粒度的减小,RDX、HMX、PETN三种样品烤燃(cook-off)热感度均逐渐升高。
In order to explore the relationship between the particle size of nitroamine explosives and their cook-off sensitivity,RDX,HMX and PETN samples with different particle sizes（centimillimeter,micron,submicron）were prepared by spray fine and dripping methods respectively.Scanning electron microscope（SEM）and laser particle analyzer were used to characterize samples.The cook-off thermal sensitivity for RDX,HMX and PETN samples were tested and analyzed by GJB772A-1997 method 608.1.Results show that thermal sensitivities of RDX,HMX and PETN increase with the reduction of particle size.
