某型高聚物粘结炸药制备工艺研究

为了系统研究不同工艺条件对炸药包覆效果的影响,以 HMX 为单质炸药,采用"溶液水悬浮"法工艺制备某新型高聚物粘结炸药(PBX),分析了分散剂、搅拌速度、温度和蒸馏时间等工艺条件对 HMX 单质炸药包覆效果的影响.试验结果表明:影响包覆效果与包覆药感度的主要因素为分散剂、搅拌速度、温度及钝感剂的加入方式.制备某新型高聚物粘结炸药较佳的工艺条件为:加入分散剂、造粒温度65 ℃、搅拌速度300 r/min、蒸馏时间30 min、钝感剂外包覆.

Study on Certain Type PBX Technique

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.
