| 摘 要： | 为了研究乳化炸药局部燃烧特性,根据法国燃烧转爆轰试验方法和美国燃烧转爆轰试验方法,在钢管中,对膨胀珍珠岩敏化的乳化炸药进行局部引燃试验,试验结果发现药温对于乳化炸药的燃烧有着重要的影响。无论是黑火药还是电热丝引燃,乳化炸药都没有实现燃烧波的传播。结果表明,在常压下乳化炸药局部燃烧不能实现燃烧波的传播,乳化炸药的燃烧存在最小临界燃烧压力。

| Abstract: | Local ignition was investigated for emulsion explosives containing expanded perlite as the density control material with small sized equipment that has been referred to the French method and American method. To evaluate the safety of its manufacturing process, emulsion explosives were ignited by hot-wire at different initial temperatures. The emulsion explosives caused partial reaction that led to the rupture of steel pipe closed to the screw cap, followed by the reaction interruption without explosion. For black powder and hot-wire ignition, emulsion explosion has not sustained combustion, and all quenched. Pressure may be a key factor to previous accident and process of production for emulsion |
