Title: Innovations of Tadashi Uragami
Introduction
Tadashi Uragami is a notable inventor based in Mino, Japan. He has made significant contributions to the field of silicone products, holding a total of four patents. His work focuses on innovative processes for fabricating porous silicone products and methods for separating liquid components from solutions.
Latest Patents
One of his latest patents is a process for fabricating a porous silicone product. This process utilizes a silicone emulsion capable of forming an elastomer through the removal of water. The silicone emulsion consists of a water emulsion of an organopolysiloxane, a cross-linking agent, and a curing catalyst. The process involves freezing the silicone emulsion and subsequently drying it, allowing water to sublimate and resulting in a porous silicone product. This product is particularly effective as a selective permeable membrane for separating liquid components from solutions containing multiple liquid components.
Another significant patent is an improved method for separating a liquid component from a solution containing two or more liquid components. This method employs a vessel divided into a solution chamber and a vacuum chamber by a permeable membrane. The membrane exhibits a superior affinity for the specific component intended for separation. The solution is placed in the solution chamber, and a vacuum is applied to the vacuum chamber, allowing the solution to evaporate and drawing the resulting vapors through the permeable membrane. This innovative approach enables the collection of the desired
