Abstract: In order toanalyzethe interfacial properties of the oil phase material and Ammonium nitrate solutionpropellantburning process,the interfacial viscosity and interfacial film yield value are measured by shear interfacial viscoelastic meter.The relationship between the interfacial viscosity of emulsifier,oil phase material,ammonium nitrate solution and interfacial yield value are analyzed in detail.The research results show that,with the increase of emulsifier content percentage,the interfacial viscosity and interfacial film yield value are increased accordingly.The interfacial viscosity value and interfacial film yield value of the two phase system that is formed by T-154 high molecular emulsifier are high.
