Detonation Characteristics of Emulsion Explosives Sensitized by MgH2
摘要
Abstract
The theoretical calculations and underwater explosion experiments are performed to investigate the detonation characteristics of the emulsion explosive sensitized by MgH2. The results show that compared with the emulsion explosives sensitized by glass microspheres, the emulsion explosive sensitized by MgH2 has a great increase in underwater explosion shock wave overpressure, specific impulse, shock wave specific energy and specific bubble energy,and it is noticeable that the shock wave overpressure and shock wave specific energy increase by over 20. 5% and 31. 0% respectively. In addition, the detonation reaction mechanism of the emulsion explosive sensitized by MgH2 is also analyzed. MgH2 plays double roles in the emulsion explosive which acts as both sensitizer and energetic material. First MgH2 is hydrolyzed in the emulsion matrix, and then a lot of hydrogen bubbles appear and distribute evenly,and at last the emulsion matrix is sensitized and can be detonated by a detonator. The explosion energy is also improved,since H2 participates in the explosion reaction and alters the detonation reaction process of the emulsion explosive.关键词
