【摘要】 利用主发药包在水中爆炸产生冲击波,次发乳化炸药药包在主发药包产生的水中冲击波动压作用下延时爆炸,研究乳化炸药在外界动态压力作用下的耐压性。研究中选用了三种国内常用乳化剂,分别改变乳化剂含量,测试了不同乳化剂种类与含量的乳化炸药临界减敏距离,并对试验结果进行了详细的讨论。研究结果表明:用Span-80乳化剂和煤矿许用乳化炸药,其耐压性随着乳化剂含量的增加而提高;而由路博润公司生产的2725高分子乳化剂及复合乳化剂制造的煤矿乳化炸药,当乳化剂含量达到一定值后,其耐压性不再随乳化剂含量变化而增加。采用合适的复合乳化剂制造的煤矿许用乳化炸药的耐压性能优于使用单一乳化剂制造的乳化炸药。更多还原

【Abstract】 In this paper, the donor charge of underwater explosion is used to produce underwater shock wave, and the second charge explodes after it is compressed by the dynamic pressure provided by the donor charge. The antipressing capability of the emulsion explosives compressed by the external dynamic pressure is studied. Three kinds of emulsifier are used, and the critical desensitization distance of the emulsion explosives with the different emulsifiers and the different quantity of the emulsifier is measured. The experiment results are discussed in detail. The results indicate: the antipressing capability of the coal mine permitted emulsion explosives increased with the increasing of the Span-80 emulsifier while the antipressing capability of the emulsion explosives with macromolecule emulsifier2725 produced by the Lubrizol company does not any more when the quantity of the emulsifier reaches a critical value, and the capability of the emulsion explosives with the composite emulsifier behaves in the same way. Therefore, the conclusion is that antipressing capability of the coalmine permitted emulsion explosives with the composite emulsifier is better than the emulsion explosives with single emulsifier.更多还原
