Title:
METHOD FOR IMPROVING DISPERSIBILITY OF AQUEOUS EMULSION AND METHOD FOR MANUFACTURING AQUEOUS EMULSION HAVING IMPROVED DISPERSIBILITY
Document Type and Number:
WIPO Patent Application WO/2016/121596
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method that is capable of efficiently separating and refining an aggregated body in an aqueous emulsion and that is capable of a high-throughput at low costs. This problem is addressed with a method for improving dispersibility of an aqueous emulsion that depressurizes a stir/mix tank 10 in which the aqueous emulsion E is placed to a pressure at which dissolved air included in the aqueous emulsion is removed, and that collides the aqueous emulsion together after the depressurizing treatment. The method for improving dispersion of an aqueous emulsion is characterized in that the aqueous emulsion E is circulated by continuously collecting, in a liquid pressurization mechanism 20, a portion of the liquid inside the tank E1 which is the aqueous emulsion inside the stir/mix tank 10 and by spraying, toward the inside of the stir/mix tank 10, a pressurized liquid E3 which is the aqueous emulsion pressurized by the liquid pressurization mechanism 20 and when spraying the pressurized liquid E3 toward the inside of the stir/mix tank 10, the pressurized liquid E3 is collided with the liquid inside the tank E1 to improve the dispersibility of microparticles in the aqueous emulsion.
