树脂微球应用于乳化炸药物理敏化技术的研究

Application of Resin Microsphere in Physical Sensitization of Emulsion Explosives

对比分析了乳化炸药树脂微球敏化与其他物理敏化方式的优点,提出了树脂微球可作为乳化炸药良好的物理敏化剂。采用树脂微球与一定比例的液体石蜡、二甲基硅油、32#机油混合后发泡,发泡效果良好,并抑制了粉尘,发泡过程及泵送过程对树脂微球破坏较小。试验结果表明:使用最佳发泡温度为150~170℃的树脂微球与32#机油混合后加热发泡,再与乳化基质进行混合敏化,得到的乳化炸药爆炸性能较好。

Advantages of resin microspheres sensitization and other physical sensitization methods of emulsion explosive were compared and analyzed.It was proposed that resin microspheres can be used as a good physical sensitizer of emulsion explosives.The foaming effect of resin microspheres mixed with a certain proportion of liquid paraffin,dimethylsiloxane and 32#engine oil is good,and the dust is restrained.The foaming and pumping process have little damage to the resin microspheres.Experimental results show that the best foaming temperature is 150-170℃.Resin microspheres with the best foaming temperature were heated and foamed after mixing with 32#engine oil,and then it was mixed with emulsion matrix for sensitization.The obtained emulsion explosive has good explosion peformances.
