摘　　要：采用挤出造粒法、溶液悬浮法、水悬浮法三种不同的工艺,选用不同的包覆材料,如氟橡胶和丁腈橡胶,对ε HNIW进行了包覆,并对包覆样品进行了扫描电镜分析和机械撞击感度测试,考察了其钝感效果及包覆工艺对样品机械撞击感度的影响。通过比较,溶液悬浮法、水悬浮法工艺制备的样品机械撞击感度要比挤出造粒法的低。在所选材料中,氟橡胶F 5作为粘结剂,采用水悬浮法工艺制备得到的以HNIW为基的混合炸药的机械撞击感度最低,特性落高值为42.5cm。The ε-HNIW was coated by several kinds of materials such as fluororubber and chemigum by means of extruding-prilling,solution suspension and water suspension methods. The coated HNIW samples were evaluated by means of SEM and impact sensitivity test in order to confirm the desensitization effect and the effectiveness of the coating methods mentioned above. Results show that the solution suspension method is better than the extruding-prilling method to desensitization of HNIW. Among coated samples,impact sensitivity of ε-HNIW coated by fluororubber F-5 by water suspension method is the lowest,value of characteristic height(H_(50)) is 42.5 cm.
