本文对导爆管激爆前后的微观形态结构,使用 JSM350CF 型扫描电镜对35个样品放大一千至六千倍进行仔细观察、拍摄与对比分析,为导爆管传爆机理研究提供了若干有益的结果;作者通过对激爆前导爆管内炸药颗粒与内壁结合关系的观察和对导爆管传爆后内壁面破坏情况观察,以及对正常导爆管吹气前后炸药颗粒在内壁面附着现象和数量的观察;初步证明:导爆管传爆属管中气固相爆炸化学反应,内壁上不存在爆炸化学反应;作者还通过对传爆后导爆管作纵向间隔连续切片观察说明:导爆管被激爆后,约需经过0.5米以上的传爆,才能获得完全反应;使用过程中必须注意这一特点。
In this paper, before and after the detonation of the detonator explosion microscopic structure, the use of JSM350CF type scanning electron microscope 35 samples magnified 1000 to 6000 times for careful observation, shooting and comparative analysis for the detonating tube explosion mechanism provides a number of useful The author through the explosion of the former detonating tube explosives particles and the inner wall of the observation of the relationship between the explosion and the explosion on the inner wall of the explosion after the observation, as well as the normal detonator before and after blowing the adhesion of explosive particles in the inner wall and The number of observations; preliminary proof: detonating tube burst tube gas-solid phase explosion chemical reaction, there is no explosion on the inner wall of the chemical reaction; the author also through the detonation of the detonating tube longitudinally spaced continuous section observation shows: After the tube is excited, about to pass after 0.5 meters of the explosion, in order to obtain complete response; the use of the process must pay attention to this feature.
