【摘要】 采用激光共聚焦扫描显微镜、接触角测试仪、显微-红外联机等表面分析技术,对JO-9159炸药柱的表面特性进行了非破坏性分析。在65℃、湿度<40%RH、贮存4个月的加速老化条件下,可得到如下变化趋势:JO-9159炸药柱在加速老化后,氟橡胶在温度的作用下向炸药柱表面发生迁移,表面自由能下降,表面分子结构未发生明显变化。更多还原

【Abstract】 JO-9159 explosive charge has been aged for four months under conditions of 65℃, and less than 40%RH. The surface characteristics of the explosive charge such as morphology, free energy and structure before and after being aged have been determined by using non-destructive measurements. The results show that the molecule structure on surface has varied unconspiciously, while the morphology has changed and the surface free energy is getting to decrease with the aging time prolonging.更多还原
