摘　　要：对以TATB为基的高聚物粘结炸药(JB1)进行了超声空化处理,并利用扫描电镜(SEM)观察了处理前后JB1炸药表面的细观形貌,用X射线能谱仪(EDS)检测了处理前后JB1炸药表面的相对元素含量。结果表明:超声空化处理可以使JB1炸药表面的粘结剂和炸药晶体的界面脱粘,使炸药晶体裸露。随着超声空化处理时间的延长,炸药晶体裸露程度加大,炸药晶体表面的小孔洞增加,表面也变得更加粗糙和疏松,起爆感度提高。Ultrasonic cavitation treatment of polymer bonded explosive （JB-1） was undertaken. Before and after treatment, the surface structure of JB-1 explosive was observed by scanning electron microscope （SEM） ,and its element concentration was analyzed by X-ray energy spectrum （EDS）. The results show that the interface between explosive crystal and binder is debonding during the ultrasonic treatment,and explosive crystals appear on the surface. With the treatment time increasing, the exposed extent of explosive crystal and the number of micro-hole on the surface of explosive crystal increase. As the surface of JB-1 explosive become rough and loose after ultrasonic cavitation treatment,its initiation sensitivity may also increase.
