摘要
In order to improve the detonation performance of emulsion explosives, a new type of emulsion explosives with TiH2 powders is developed. The influences of the amount of sensitizers GMs and energetic additives TiH2 on explosion characteristics of emulsion explosives are studied to determine the optimum compositions. Underwater explosion and brisance testing experiments show that, compared to traditional GMs sensitized emulsion explosives, the shock wave specific impulse I and total energy E of GMs-TiH2 sensitized emulsion explosives are improved significantly, and the effect of TiH2 powders on improving the explosion power of emulsion explosives is better than that of Ti powders. The brisance of GMs-TiH2 emulsion explosives is 23.80mm compression of lead block, 7.7mm more than that of the emulsion explosives sensitized by GMs alone. Therefore, the hydrogen containing material TiH2 could be a promising energetic additive for developing high-power emulsion explosives.
