PROBLEM TO BE SOLVED: To provide a method capable of efficiently separating and refining aggregates in an aqueous emulsion and capable of mass treatment at a low cost, and an aqueous emulsion in which aggregates are sufficiently separated and refined.SOLUTION: Provided is a method for improving the dispersibility of an aqueous emulsion E where the pressure in a stirring mixing tank 10 charged with an aqueous emulsion E is reduced to the one at which dissolved air contained in the aqueous emulsion E is removed, and each aqueous emulsion E after the pressure reduction treatment is collided. Also provided is a method for improving the dispersibility of the aqueous emulsion E where a part of a tank-inner liquid E1 as the aqueous emulsion E present in a stirring mixing tank 10 is continuously taken inside a liquid pressurization mechanism 20, a pressurized liquid E3 as the aqueous emulsion pressurized by the liquid pressurization mechanism 20 is jetted toward the inside of the stirring mixing tank 10 to circulate the aqueous emulsion E, and the pressurized liquid 3 is collided with a tank-inner liquid when being jetted toward the inside of the stirring mixing tank 10, thus the dispersibility of the fine particles in the aqueous emulsion E is improved.SELECTED DRAWING: Figure 2 |
