The Applied Study On Explosives From Obsolete Propellants

A low detonation velocity explosive with medium density (lg/cm3) and proper power (>320ml). which made from obsolete Propellant by controlling the granularity and adding the inhibitor, is studied in this thesis; The distribution of water in the powdery propellant is described, the effect of detonation velocity from different granularity of powdery propellant is studied and the simulated mathematical model on leakage of water in low detonation velocity explosive is also showed Furthermore, the method involved in controlling the leak of water in explosive is provided. Meanwhile the effect of inhibitor is experimented Some of formulations and processes of low detonation velocity explosive are given in details. The detonation velocity can be controlled at about 2000m/s with reliable detonation propagation performance. The affection of the temperature in the test is trivial. The oil exploration tests show that the low detonation velocity explosive is better than traditional high detonation velocity explosive in improving the resolution of the geological layer. Propellant can be used to make perfusing explosive. The cavities of propellant are filled with mixture of oxide, water and polymer. The mixture will turn into the gel after a certain period. The perfusing explosive is equipped with performance of high density (>1.4g/cm3), anti-water and high detonation velocity. Its mechanical character is also discussed in this paper. Combining the perfusing explosive with the low detonation velocity explosive can be used to make special detonation shock shape. A plane shock is designed by Matlab program in this paper. Powdery propellant, oxide, polymer and agent can be mixed to make slurry explosive, the sensitivity of slurry explosive is discussed; Slurry explosive can be made into special shape destructor, It results of the area , height and setting angle of explosive is related to the destructed effect; The destroying effect of slurry explosive is also studied from the experiment in the air and on thesteel plate.
