摘要

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- 8μm, 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.
