【摘要】 内壁散附微量药粉的导爆管现已普遍应用,但对其传爆机理的研究目前还较欠缺。本文对导爆管的传爆物理因素与化学反应形态进行了高速摄影与光电测速,全面分析了影响其稳定传爆的原因,得出了导爆管在真空下仍能正常传爆且其爆速基本不变的结论,初步提出了导爆管传爆的内管道综合效应机理模型。该观点无疑对导爆管的应用和发展具有一定的指导意义,特别是在有瓦斯粉尘爆炸危险的地点应用具有重要价值。更多还原

【Abstract】 Nonels,which absorbed slight amount of powder on its internal wall,have been widely used,however,not much investigation of its detonation mechanism has been done.A comprehensive analysis is made by the authors on the factors that affect steady detonation,including physical factors and chemical reaction morphology of Nonels by using high speed camera and photo-electric velocity measurement. A conclusion is drawn that detonation of Nonel is normal in vacuum condition,and the velocity can be basically kept unchanged.A model,representing mechanism of combined effects of inner Nonelin detonation is preliminarily set up. The viewpoints of the authors have never been published in the literatures at home and abroad.It is no doubt that these viewpoints can give guidance to application and development of Nonel,and are of important value to their application in localities prone to gas and dust explosion.更多还原
