Effect of Perlite Content on Performance of Emulsion Explosive in Under-Water Environment

Emulsion explosive has been widely used in underwater blasting construction. To study the effect of perlite content on the performance of emulsion explosives under deep water conditions, the performance of emulsion explosives with different applied pressures and different perlite contents was studied by using the self-built underwater explosion test system. The results show that, with the increase of pressure in the water, the energy of emulsion explosive with different content of perlite as sensitizer has a decreasing trend, which is consistent with the actual situation, and when the perlite content is 4%, the sensitized bubble is adiabatically compressed, and the hot spot fully explodes, and its detonation performance is the best.
