Unconventional Emulsion Explosives with Low Detonation Velocities
Detonation velocities of unconventional emulsion explosives containing epispastic polystyrene (EPS) micro-balloons were studied experimentally and theoretically. Fine-particle lithium and zinc oxides have been prepared by the detonation of emulsion explosives of the metal nitrates, M (N3)x (M = Li, Zn) as oxidizers and paraffin as fuels, at a low velocity. For the calculations in which the first set of decomposition products is assumed, predicted heats of detonation of emulsion explosives with the product H20 in the gas phase have a deviation of 586kj/kg from results with the product H2O in the liquid state. The results obtained enable a comparison of the usefulness of both calculating and measuring methods. The influence of lithium and zinc nitrates contained in the emulsion matrix on the detonation velocities of the explosives was discussed.
