Abstract

In order to obtain a pressed fitting PBX that has good safety performance, 3-nitro-1, 2, 4-triazol-5-one(NTO) and HMX is used as the base explosive to make NTO/HMX based pressed fitting PBX by water slurry method. Solubility of NTO in water has been determined. The influences of the ratio of water and explosive compound, and agitating rate on the coating effect are studied. The effect of particle size of explosive compound on the impact sensitivity is also investigated. The detonation velocity of PBX has been determined. The result indicates that NTO has high solubility in water. At room temperature, the saturated NTO solution can be used to make molding powder. The optimal technical conditions are 1.6:1 of water and explosive compound ratio (V/M) and 500 r/min of agitating rate. After refining particle size of NTO and HMX, the impact sensitivity is only 15.3%, which is decreased by 43%. The detonation velocity of PBX was 8 200 m/s, which is above 95% of theoretical maximum detonation velocity.
