摘要
Abstract
In the production of emulsion explosives,in order to quickly characterize the stability of the emulsified matrix,the demulsification effects of liquid demulsifiers alkylphenol polyoxyethylene ether(OP-10)and dehydrated sorbitol monooleate polyoxyethylene ether(Tween80),solid demulsifiers sodium dodecyl sulfate(SDS)and sodium oleate on the emulsified matrix were systematically investigated.The degree of demulsification was quantitatively evaluated through vis-cosity measurement,ammonium nitrate crystallization rate analysis,rheological property testing,and ultrasonic attenuation characterization.The influence of various factors on demulsification efficiency was explored through orthogonal experiments.Meanwhile,the influence of microstructure on macroscopic phenomena was revealed by microscopic observation.The re-sults show that the demulsification effect of liquid demulsifier OP-10 was significantly better than that of Tween80.In solid demulsifier systems,the demulsifier content is the main factor affecting the demulsification rate.Meanwhile,increasing the temperature and prolonging the action time can effectively promote the demulsification process.In rheological test,it shows that the strength and yield stress of the interfacial film are significantly reduced by the demulsifier.There is a good correla-tion between the variation of ultrasonic attenuation coefficient and the degree of demulsification.A quantitative evaluation system for the degree of demulsification has been established,providing references for the quality assessment and rapid de-tection of emulsified matrix in industrial applications.关键词
