At present,there are few studies on the effect of the sensitization mode on the stability of emulsion explosives under the effect of ultrasound. The emulsion matrix and the emulsion explosive prepared by using 3 different sensitization methods were effected by ultrasonic wave respectively,and formaldehyde titration was used to measure crystallization quantity,so as to measure the demulsification degree of the four samples. The experimental results showed that the effect of ultrasonic wave obviously improves...
