In order to study the effects of different craft conditions on explosive cladding, take HMX as single compound explosive, adopt water suspension method to make new PBX. Analyze the influence of technique conditions, such as dispersant, agitating rate, temperature and distil time, on HMX single compound explosive coating. The test results show that dispersant, agitating rate, temperature, distil time and desensitizer add methods were the main factors affecting the preparation quality and sensitivity of the molding powder. The optimal technique conditions for PBX: add dispersant, reaction temperature is 65℃, agitating rate is 300r/min, distil time is 30 minute, and enwrap desensitizer outside layer.
