PREPARATION PROCESS AND DETONATION CHARACTERISTICS OF THE EMULSION EXPLOSIVES USED FOR DETONATION SYNTHESIS

A new type of emulsion explosive used to prepare nano-MnFe2O4 powders via detonation method was prepared,the parameters of the preparation process,detonation velocities and characteristics of the explosives were discussed,tested and researched respectively.Results indicated that the preparing process of the emulsion explosives was more rigid than that of traditional emulsion explosives.However,pure emulsion base could not be detonated by detonator except of adding some RDX as sensitizer.Detonation velocity test indicated that the emulsion explosives had relatively lager critical detonation diameter(32mm) and could be stably detonated with the velocities closed to those of traditional explosives.The detonation state of the emulsion explosives could be judged and evaluated by detonation products,and the structural uniformity of detonation reaction could be improved by adding ammonium nitrate in the oxidants of the explosives.
