树脂微球应用于乳化炸药物理敏化技术的研究

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。

Application of Resin Microsphere in Physical Sensitization of Emulsion Explosives

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.
