Title: Kosuke Takeshige: Innovator in Cation-Exchange Membrane Technology
Introduction
Kosuke Takeshige is a notable inventor based in Shinnanyo, Japan. He has made significant contributions to the field of membrane technology, particularly in the development of cation-exchange membranes. With a total of 2 patents, his work has implications for various industrial applications.
Latest Patents
Takeshige's latest patents include a method of producing a cation-exchange membrane with a roughed surface. This innovative method involves mixing silica powder with water to create a suspended or pasty mixture. The mixture is then supported on art paper or filter paper and dried to form a silica powder layer. This layer is adhered to a membrane composed of perfluorocarbon polymer through heating and pressing. Finally, the silica powder layer is removed using a caustic alkali aqueous solution.
Another significant patent is focused on the purification of alkali carbonate containing a fluorine compound. In this process, the crude alkali carbonate is dissolved in an aqueous solution or suspension of magnesium bicarbonate. This method effectively transfers the fluorine impurity into a colloidal flocculated precipitate, thereby substantially separating the fluorine from the aqueous solution of the alkali carbonate.
