| 中文摘要: |
| 通过水下爆炸与爆破切割实验,研究了新型材料敏化的乳化炸药爆炸能量输出特性。研究结果表明,材料CMLS敏化的乳化炸药相对玻璃微球敏化的乳化炸药在爆炸威力上有了很大的提高。CMLS型乳化炸药采用的是动态敏化技术,在引爆过程中,CMLS受压分解产生气体,从而引入均匀分布的小气泡,达到了敏化的目的。它保证了初始高密度装药,并且避免了由于敏化气泡破坏而造成的半爆和拒爆现象。材料CMLS分解产生的物质是含能基团,参与乳化基质的爆轰反应,因此其总输出能量会大于现有乳化炸药的输出能量。上述结果对新型乳化炸药设计具有指导意义。 |

| 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. |
