Title (EN) POROUS HOLLOW FIBER MEMBRANE AND METHOD FOR PRODUCING SAME
(FR) MEMBRANE POREUSE À FIBRES CREUSES ET PROCÉDÉ POUR SA PRODUCTION
(JA) 多孔質中空糸膜及びその製造方法
Abstract:
(EN) The present invention provides a porous hollow fiber membrane suitable for the removal of minute substances, e.g., viruses, contained in a liquid. The present invention relates to a porous hollow fiber membrane which is provided with a separation-functioning layer containing a fluororesin, has a gas diffusion amount of 0.5 to 5.0 mL/m2/hr as measured in a diffusion test, and also has foaming points at a density of 0.005 to 0.2 point/cm2 as measured in a foaming test under the immersion in 2-propanol.
(FR) La présente invention concerne une membrane poreuse à fibres creuses appropriée pour l'élimination de substances minuscules, par exemple, des virus, contenues dans un liquide. La présente invention concerne une membrane poreuse à fibres creuses qui est pourvue d'une couche fonctionnelle de séparation contenant une résine fluorée, qui possède une quantité de diffusion gazeuse de 0,5 à 5,0 ml/m2/h telle que mesurée dans un essai de diffusion, et qui possède également des points de moussage à une densité de 0,005 à 0,2 point/cm2 tel que mesuré dans un test de moussage sous immersion dans du propanol-2.
(JA) 本発明は、液体中のウイルス等微小物の除去に好適な多孔質中空糸膜を提供する。本発明は、フッ素樹脂を含有する分離機能層を備え、ディフュージョン試験における気体拡散量が、0.5~5.0mL/m/hrであり、かつ、2-プロパノール浸漬下での泡立ち試験における泡立ち点が、0.005~0.2個/cmである、多孔質中空糸膜に関する。
