Title: Akihiro Okubo: Innovator in Membrane Support Materials
Introduction
Akihiro Okubo is a notable inventor based in Itano-gun, Japan. He has made significant contributions to the field of membrane support materials, holding a total of 3 patents. His innovative work focuses on enhancing the performance and functionality of membrane systems.
Latest Patents
One of Okubo's latest patents is for a membrane support material. This material serves as a support for adhering a membrane to a membrane attachment surface. It consists of a plurality of non-woven fiber sheets, which are three-dimensional fiber aggregates, layered together and processed through thermal and pressure techniques. This process bonds the fibers of the non-woven sheets to form a single sheet of support material. Each layer of non-woven fiber sheet has a different longitudinal-to-lateral tensile strength ratio (k), which is the ratio of the tensile strength in the lengthwise direction to that in the width direction. In the processed state, the support material's membrane attachment surface exhibits curvature in the lateral direction with an outward protruding center region.
Another significant patent involves a laminated material of segregating membrane and segregating membrane supporting material, along with its method of manufacture. This segregating membrane supporting material is a three-dimensional assembly of fibers that are thermo-compressed into non-woven fabric. The fibers are joined together in sheet form, and the material includes at least 10 weight % polyacrylonitrile-based synthetic fibers. The thermo-compression process results in an overall bulk density that is 40% to 75% of the density of the fibers that comprise the non-woven fabric.
