Influence of Compound Sensitizers on Compression Resistance of Deep Water of Emulsion Explosives

Abstract:

compound sensitizing agent is an important component of the emulsion explosive, by using reusable experiment device to simulate the deep charging environment, study compound sensitizing agent on the properties of emulsion explosive deep water pressure resistance. Experimental results show that the mixed sensitizing, the deep water pressure resistance of three kinds of emulsion explosive performance award to him a bad order: glass microspheres + perlite + sodium nitrite sensitization, glass microspheres + perlite and sensitizing sodium nitrite sensitization. Compound containing glass microspheres sensitizer, the measurement of explosive performance closer to sensitization performance when only glass microspheres, perlite, the addition of sodium nitrite on the explosive performance contribution is small. Sodium nitrite and perlite mixed sensitizing, explosive detonation "hot spots", first class formation is chemical sensitization is given priority to, only a minority of perlite as "hot spots", the measurement of explosive performance closer to use sodium nitrite sensitization performance.
