Through the pneumatic spray method that is the combination with a chemical re-crystallization and physical function to improve the re-crystallization thinning effect of HMX explosive

the core technology is the jet dispersive mixing of explosive solution and non-solvent.Adopting this method-HMX as raw material and dimethyl sulfoxide as solvent

the orthogonal experiment was designed and the best technological parameters of influencing factors of explosive thinning were studied.The results show that when water temperature is 0 ℃

injection pressure is 0.5 MPa

the speed of inputting drug is 40 mL/min

the best volume ratio of water and solution(the amount of water joined to spray pot) is 3×5 500 mL

refining effect of HMX is the best when solution temperature is 50 ℃.
