This paper introduces structure and detonation propagating of K · K non priming explosive detonator. The initiation delay time, axial and side exported energy were tested, which should be paid attention during the use of nonel tube detonator. 该文介绍了K·K无起爆药雷管的结构与传爆过程,测试了其点火延迟时间、侧向与轴向爆炸后能量输出情况,提出了作导爆管雷管使用时必须注意的一些问题。
