Preparation of Ultra Fine Explosive HMX and RDX Using High Speed Impinging Streams

Zhang Xiaoning Xu Gengguang Wang Tingzeng (Department of Engineering Safety, Beijing Institute of Technology, Beijing100081)  
Aim To study the new methods of preparing ultra fine HMX and RDX and their technological factors affecting the preparation. Methods High speed impinging streams of suspending liquid were used. Results The particles of HMX and RDX can be crushed into sub micron effectively by high speed impinging streams method. The effective particle diameter is 612 2 nm and the particle size distribution is 236 5~1 286 0 nm. Conclusion The pressures and times of processing are the main factors that affect the particle sizes and particle size distribution. The most important factor affecting the crush degree is the pressure. The times of processing affect the mean particle diameter and the particle size distribution, not the crush lower limit.
