The certain type projectile charge will exist exudation when the storage temperature is sustainably over 70℃ for a period of time, carry out safe analysis for it. Analyze the high temperature exudation content of projectile charge, and select section to test the deterrent content and mechanical sensitivity. The test results show that exudation from the charge is uniform. The exudation components are stearic acid and ozokerite that is no safety risk. After high temperature storage, the explosive are recoated with the mechanical sensitivity decreases, which will not affect the safe use.
