摘要:
为了研究黏结剂对TKX50单质炸药的机械感度和成型性能的影响，通过粒度分布试验分析了高速剪切粉碎机处理TKX-50原料后的形貌和粒度。借助机械感度试验研究了TKX-50原料、TKX-50预处理样品、黏结剂氟橡胶和含能热塑性弹性体ETPE包覆处理后TKX-50炸药的安全性能；利用压制成型试验分析了压力、温度对含不同黏结剂的TKX-50基压装炸药成型性的影响规律。结果表明，预处理后TKX-50的粒度变小，分布变窄，形貌比较规整，机械感度降低；氟橡胶或ETPE包覆处理TKX-50炸药的机械感度降低，在一定程度上提高了炸药的安全性；压力、温度对含氟橡胶或ETPE黏结剂的TKX-50基压装炸药的成型性影响较大，且ETPE黏结剂的TKX-50基混合炸药的成型性较好，特定压力和温度条件下其相对密度可达98.1%以上。
Abstract:
A series of experiments was conducted in current research to better understand the influence of binder on the mechanical sensitivity and molding performance of TKX-50-based pressed explosive. They were focused on the morphology and particle size of TKX-50 raw material processed by high-speed shearing mill using scanning electron microscopy, the safety performance of TKX-50 explosive at different stages of raw material, after treatment and coating by various binders such as fluororubber and ETPE by mechanical sensitivity test, and the moldability of TKX-50-based pressed explosives with different binders under assigned pressures or temperatures by press molding test. Results show smaller particle size, narrower size range, more regular appearance, and reduced mechanical sensitivity of TKX-50 after treatment. The lower mechanical sensitivity of TKX-50 explosives coated with fluororubber or ETPE may improve its safety to a certain extent. Pressure and temperature have a greater impact on the moldability of TKX-50-based pressed explosives containing fluororubber or ETPE binder. TKX-50-based explosive with ETPE binder has good moldability and can reach a relative density of more than 98.1% under specific pressure and temperature.
