Influence of clay particle on stability of emulsion

The influence of clay particle on Jilin oil emulsion and oil-water interfacial property has been studied through dynamic model analysis, Turbiscan stability analysis and single drop method. The results showed that the dynamic reaction rate constant of system first increased then decreased, and the stability of emulsion first increased then decreased as the concentration of clay particle improved. It also showed that back scattered light of emulsion decreased less, and coagulation stability of system increased with addition of clay particle, which promoted drain and coalescence of droplets as joint medium. At the same time, it showed that drain time of droplets and survival half life increased, fracture velocity constant decreased and strength interfacial film improved because of adsorption of clay particle.
