  • Abstract

    To study the influence of glass microsphere content on underwater explosion energy of emulsion explosives, emulsion matrix was mixed with 2%,3%,4%,5% and 6% glass microspheres respectively to make five kinds of emulsion explosives, and underwater explosions were tested under the same experimental conditions. Results show that glass microsphere content has a great influence on underwater explosion energy of emulsion explosives, and that the energy parameters of underwater explosion rise with the increase of glass microsphere content within a certain range. When the mass fraction of glass microspheres is 4%, underwater explosion energy output of emulsion explosives reaches maximum, and underwater explosion energy decreases when the glass microspheres content further increases.
