Title (EN) COMPOSITE SEMIPERMEABLE MEMBRANE
(FR) MEMBRANE SEMI-PERMÉABLE COMPOSITE
(JA) 複合半透膜
Abstract: front page image
(EN)A composite semipermeable membrane which comprises a finely porous support membrane composed of a base material and a porous support and a layer having a separation function, comprising a polyamide and formed on the finely porous support membrane, and which is characterized in that the polyamide has an irreversible endothermic heat amount of 275 J/g or more in a temperature range from -20˚C to 150˚C in the initial temperature-rising stage which is measured by a temperature-modulated DSC method. Provided is a high-performance composite semipermeable membrane having high chemical resistance, a high water permeation amount and a high removal ratio.
(FR)L'invention concerne une membrane semi-perméable composite qui comprend une membrane de support finement poreuse constituée d'un matériau de base, d'un support poreux et d'une couche ayant une fonction de séparation qui comprend un polyamide et qui est formée sur la membrane de support finement poreuse, ledit polyamide présentant une quantité de chaleur endothermique irréversible supérieure ou égale à 275 J/g dans une plage de températures allant de -20 ˚C à 150 ˚C lors de l'étape d'augmentation initiale de la température qui est mesurée par un procédé d'ACD modulé par la température. L'invention concerne une membrane semi-perméable composite haute performance caractérisée par une résistance chimique, un degré de perméation d'eau et un taux d'élimination élevés.
(JA) 基材と多孔性支持体とからなる微多孔性支持膜上にポリアミド分離機能層を形成してなる複合半透膜であって、温度変調DSC法を用いて測定した初期昇温過程における-20~150℃の範囲での該ポリアミドの不可逆的吸熱量が275J/g以上であることを特徴とする複合半透膜。 高い耐薬品性と高透水量、高除去率を有する高性能な複合半透膜を提供する。
