The effects of nonionic surfactant TX and AEO emulsified white oil on the anti-polymerization and stability of the emulsions were investigated experimentally with the changes of electrolyte concentration and surfactant HLB values. A static mechanical model was established for the above system, The influence of interface potential and electrolyte concentration on the force between two liquid droplets was investigated by analyzing the contradiction between the simulation results and the experimental phenomena in the model. It is pointed out that in the collision process of liquid droplets, the electrostatic repulsive force , There is a tendency to be squeezed into the disperse phase bead, resulting in the deforming of the interface and the formation of the void region of the surfactant. A micro-mechanism of bead aggregation in emulsion
