HMX/TATB基PBX的感度与表面形态的关系探索

The Sensitivity and the Surface Characterization of HMX/TATB BASED PBX

报道了以 HMX/ TATB基的 PBX中 ,蜡的加入量和加入方式对配方的机械感度如撞击感度、摩擦感度、特性落高有明显的影响 ,但对配方的热感度如 5 s爆发点、10 0 0 s热爆炸临界温度影响不大。同时结合扫描电镜 (SEM)和光电子能谱 (XPS)的测试结果分析了造型粉的表面包覆形态和感度之间的关系。

In order to obtain a formulation with high energy output and low sensitivities, the influence of the amount and the process of wax used in the HMX/TATB based molding powders on the sensitivities were studied. The results show that the influence of the amount of wax on the mechanical sensitivity, such as impact test, friction test, and H 50 is very large, but on the thermal sensitivitiy such as 5s exploding point and 1000s thermal exploding citical temperature is little. At the same time the surface characterization of the molding powders was studied by scanning electric microscopy (SEM) and X ray photoelectron spectroscopy (XPS), the relation of the surface properties and the sensitivities was discussed too.
