摘要:
Nanoscale particles of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) are obtained by means of the bidirectional superfine mill with controlled solid loadings and rotation speeds. 500g of raw RDX is addressed per batch. The size distribution of the nanoRDX is characterized by a laser particle size analyzer. The TEM observation shows that the nanoparticles are semispherical having an average size of about 60 nm. The nanoRDX is free of contamination as detected by XPS. The peak thermal decomposition temperature of nanoRDX shows a decrease of 1.6 ℃, compared with that of raw RDX. Significant decrease happens in the friction, impact and shock sensitivities, especially a decrease of 59.9% in the shock sensitivity. It is expecting to promote largescale manufacture of sensitivityreduced nanoRDX which would work for insensitive munitions.
Abstract:
使用双向旋转球磨机,通过控制固含量和转速,成功制备了纳米RDX。实验过程中,RDX单次处理量为500 g。采用激光粒度仪表征纳米RDX的粒度分布,并通过透射电子显微镜(TEM)观察纳米RDX颗粒的大小和形貌,发现其平均粒径在60 nm左右,呈类球形。通过X光电子能谱(XPS)分析表明,纳米RDX中不含有污染物。与原料RDX相比,纳米RDX的热分解峰温提前了1.6 ℃;其机械感度降低明显,尤其是冲击波感度,降幅为59.9%。结果表明:有望实现纳米RDX的大规模生产并为不敏感弹药服务。
