摘要：
Preliminarily results on the reaction mechanism of detonation of composite emulsion explosives sensitized by MgH2, which simultaneously plays the role of an energetic material, are presented. Compared to emulsion explosives sensitized by glass microspheres, emulsion explosives sensitized by magnesium hydride have a different reaction mechanism of detonation. The shock wave overpressure, specific impulse, shock wave energy, and bubble energy are all greatly increased with the use of MgH2, and it is noticeable that the shock wave overpressure and shock wave energy increase by 17% and 24%, respectively. In addition, emulsion explosives sensitized by MgH2 improve significantly in terms of detonation velocity and brisance. These emulsion explosives also meet safety requirements.
