Influence of glass microspheres content on underwater explosion energy of emulsion explosives

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.
