Abstract:
(EN) [Problem] To provide a porous hollow fiber membrane having excellent chemical resistance and mechanical strength, a production method therefor, and a filtration method using the porous hollow fiber membrane. [Solution] A porous hollow fiber membrane (10) in which: the porous hollow fiber membrane (10) includes at least a first solvent and a second solvent; the first solvent is at least one compound selected from a sebacic acid ester, a citric acid ester, an acetyl citric acid ester, an adipic acid ester, a trimellitic acid ester, an oleic acid ester, a palmitic acid ester, a stearic acid ester, a phosphoric acid ester, a C6–30 fatty acid, and an epoxidized vegetable oil; the second solvent differs from the first solvent, and is at least one compound selected from a sebacic acid ester, a citric acid ester, an acetyl citric acid ester, an adipic acid ester, a trimellitic acid ester, an oleic acid ester, a palmitic acid ester, a stearic acid ester, a phosphoric acid ester, a C6–30 fatty acid, and an epoxidized vegetable oil; and the porous hollow fiber membrane (10) has a three-dimensional mesh structure.
(FR) La présente invention vise à fournir une membrane poreuse à fibres creuses ayant une excellente résistance aux produits chimiques et une excellente résistance mécanique, son procédé de production, et un procédé de filtration utilisant la membrane poreuse à fibres creuses. À cet effet, l'invention concerne une membrane poreuse à fibres creuses (10) dans laquelle : la membrane poreuse à fibres creuses (10) comprend au moins un premier solvant et un second solvant; le premier solvant est au moins un composé choisi parmi un ester d'acide sébacique, un ester d'acide citrique, un ester d'acide citrique d'acétyle, un ester d'acide adipique, un ester d'acide trimellitique, un ester d'acide oléique, un ester d'acide palmitique, un ester d'acide stéarique, un ester d'acide phosphorique, un acide gras en C6-30 et une huile végétale époxydée; le second solvant diffère du premier solvant, et est au moins un composé choisi parmi un ester d'acide sébacique, un ester d'acide citrique, un ester d'acide citrique d'acétyle, un ester d'acide adipique, un ester d'acide trimellitique, un ester d'acide oléique, un ester d'acide palmitique, un ester d'acide stéarique, un ester d'acide phosphorique, un acide gras en C6-30 et une huile végétale époxydée; et la membrane poreuse à fibres creuses (10) a une structure de maille tridimensionnelle.
(JA) 【課題】耐薬品性、および機械的強度に優れた多孔性中空糸膜、その製造方法、および多孔性中空糸膜を使用したろ過方法を提供する。 【解決手段】多孔性中空糸膜(10)が少なくとも第1の溶剤及び第2の溶剤を含み、第1の溶剤が、セバシン酸エステル、クエン酸エステル、アセチルクエン酸エステル、アジピン酸エステル、トリメリット酸エステル、オレイン酸エステル、パルミチン酸エステル、ステアリン酸エステル、リン酸エステル、炭素数6以上30以下の脂肪酸及びエポキシ化植物油から選択される少なくとも1種であり、第2の溶剤が第1の溶剤と異なり、セバシン酸エステル、クエン酸エステル、アセチルクエン酸エステル、アジピン酸エステル、トリメリット酸エステル、オレイン酸エステル、パルミチン酸エステル、ステアリン酸エステル、リン酸エステル、炭素数6以上30以下の脂肪酸及びエポキシ化植物油から選択される少なくとも1種であり、3次元網目構造を有する多孔性中空糸膜(10)とする。
