Abstract

Abstract

A pressure desensitization degree parameter was proposed to characterize desensitization of emulsion explosive and offer a quantificationally analyzing tool for studying its action mechanism. Pressure desensitization degrees were calculated with parameters, such as peak pressure, its logarithm, shock wave energy and total energy of explosion shock wave, which were respectively produced by emulsion explosive before or after desensitization. Calculated pressure desensitization degrees were similar with different parameters. Calculation with peak pressure was simple and the result calculated with shock wave energy was better. Research results show that pressure desensitization degree calculated with shock wave parameters can reflect the pressure desensitization essence of emulsion explosive.
