Effect Of Wax That Adsorbed In Oil-Water Interface On The Properties Of Water-in-Oil Emulsion

In recent years,the study of multiphase wax deposition mechanism shows that the adsorption of wax in oil-water interface and the diffusion path of wax molecules will influence the process of wax deposition.Therefore,the study of the adsorption of wax in oil-water interface is of great significance in understanding the process of multiphase wax deposition from the mechanism.This paper uses 60# fully refined paraffin and 100# mineral oil to prepare model oil.The oil-water interface properties of model oil at different temperatures,different wax content and different surfactant concentrations were tested,according to the change of oil-water interface properties,the conditions that wax adsorb in oil-water interface were obtained.Based on the research,the effect of wax that adsorbed in oil-water interface on the stability of water in oil emulsion was studied.And this paper uses the Gibbs formula to calculate the adsorption quantity under different water content,different temperature and different stirring speed.Finally,the relevant parameters in the formula of effective diffusion coefficient of wax molecules are deduced theoretically,the method that calculates the effective diffusion coefficient of wax molecules is improved.Based on the above research,a formula for calculating the diffusion coefficient of wax molecules is proposed.
