摘要
本文利用撞击流法和微乳控制技术成功地制备了纳米粒度的奥克托今 (UFHMX)。实验表明 ,Zeta电位对分散HMX和分离UFHMX起着重要的作用。当HMX的水乳液液流在压力为15 0MPa、撞击速度约 10 0 0m /s的情况下进行超微化处理时 ,可得到粒度分布范围较窄的球形纳米UFHMX颗粒。这时颗粒的有效平均粒径为 184 .4nm ,最小颗粒为 12 .4nm ,最大颗粒为 4 6 5 .7nm ,比表面积为 2 8.4 2m2 / g .
Nanometer size ultra fine HMX particles had been prepared successfully using the impinging streams method and micro emulsion control technique. Experimental results showed that the Zeta potential plays an important role in the dispersion of HMX and the separation of UFHMX. Spheric nanometer HMX particles in narrow distribution range could be obtained under the condition of 150MPa pressure and 1000 m/s impact velocity. Effective average particle diameter of the sample obtained under that condition amounted to 184 4nm, with a minimum diameter of 12.4nm and a maximum diameter of 465.7nm, the specific surface area being 28.42m 2/g.
