The Effect of the Hydrogen Containing Material TiH2 on the Detonation Characteristics of Emulsion Explosives.

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 23.80 mm compression of lead block, 7.7 mm 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. [ABSTRACT FROM AUTHOR]
