| Abstract: | In order to avoid defects of the ultra-fine explosive which was easy to agglomerate in the course of general coating,ultra-fine booster explosive based on sub-micron HMX was prepared by supercritical anti-solvent(SAS) technique.The influence of technical condition on the coating effect was studied.Test results show that the major factors affecting coating effect of sb-micron HMX are: initial solution concentration,system temperature,system pressure,average pressure increase velocity and average pressure decrease velocity.Under the conditions of volum of ethyl acetate 20 mL,system pressure 9.5 MPa,system temperature 50℃,average pressure increase velocity 3.0 MPa/min,average pressure decrease velocity 4.0 MPa/min,the grain diameter of ultra-fine booster explosive is 4-8 μm.Its characteristic drop of impact sensitivity is the highest and gap thickness of shock wave sensitivity is decreased by 35.27% compared with that of JO-9C(Ⅰ) booster explosive. |
