Rapid Prediction of Effect of Ferrous Iron on the Stability of Emulsion Explosives Matrix

Designing an emulsified matrix formulation in the laboratory, ratios of emulsifier span-80 and T-152 were 1:0, 2:1, 1:2, 0:1 respectively. Then preparation was added by 0.04% Fe2+ impurities emulsion matrix. Based on water-soluble test method, we used ultrasonic instrument to focus containing impurities. The results show that crystallization amount adding is more than not .Impurities has damaging effects stability its interface membrane. At same time, ultrasound can accelerate speed demulsification As composite emulsifiers span-80: T-152=1:2, best.
