Detonation Pressure of an Emulsion Explosive Sensitized by Polymer Microballoons

  • Published:
Combustion, Explosion, and Shock Waves Aims and scope

Abstract

The detonation pressure of an emulsion explosive sensitized by polymer microballoons was determined using two loading schemes: a detonation wave normally incident on the target and sliding detonation. The initial density of the explosive ranged from 0.2 to 1.2 g/cm3. The obtained pressures are in good agreement with the calculated values known from the literature and are compared with the detonation pressures of an emulsion explosive sensitized by glass microballoons. The reaction time and the isentropic exponent of the emulsion explosive were calculated.
