Study of Explosion Characteristics of Emulsion Explosive Sensitized by New Sensitizer
新材料敏化的乳化炸药爆炸特性研究

Through underwater explosion experiment and explosion cutting experiment, energy output characteristic of emulsion explosive sensitized by new sensitizer was studied. Results show that compared with emulsion explosive sensitized by glass microspheres, the emulsion explosive sensitized by CMLS has a great improvement on explosive power. Dynamic sensitizing technology was adopted in CMLS type emulsion explosive preparation, so during detonation process, CMLS is decomposed and produces gas due to pressure, then small bubbles are distributed uniformly in the emulsion matrix, at last the emulsion matrix is sensitized. New sensitizer ensures charge with a high initial density, and can avoid half explosion and misfire due to the damaged of sensitization bubbles. The materials produced by CMLS decomposition are energetic groups which participate in detonation reaction, so the total energy output increases over 30%. It is expected that this new emulsion explosive will be further developed and applied extensively in practice.
