摘要:
采用激光粒度仪跟踪粒度分布，用扫描电子显微镜（SEM）和透射电子显微镜（TEM）观察颗粒大小和形貌；通过热重（TG）和差示扫描量热法（DSC）分析了使用HLGB-10型粉碎机批量制备纳米黑索今 (RDX)的热分解特性，并测定了5 s爆发点和感度。研究结果表明，制备的纳米RDX粒度分布窄；与原料RDX相比，活化能和5 s 爆发点稍有降低，热安定性基本不变，静电感度与火焰感度与原料RDX相当；摩擦、撞击和冲击波感度分别比原料RDX降低了37.5%、 92.8%和51.0%。
Abstract:
The particle size distribution of nano-RDX was traced by the laser particle size analyzer. At the same time, the particle size and the morphology of nano-RDX were characterized through the SEM and the TEM. The thermal decomposition of nano-RDX which was prepared in batches by the pulverized machine HLGB-10 was examined by the TG/DSC simultaneous thermal analyzer. Furthermore, the explosion temperature in five seconds and the sensitivities were measured. Results show that the nano-RDX gets a narrow particle size distribution. Compared with the coarse counterpart, the activation energy and the explosion temperature in five seconds decrease slightly, and the thermal stability remains unchanged. The electrostatic sensitivity and the flame sensitivity of nano-RDX are the same as that of the coarse counterpart. while friction, impact and shock wave sensitivity of nano-RDX respectively decrease by 37.5%, 92.8% and 51.0%.
