Vinylidene Fluoride Resin Hollow Filament Porous Membrane, Water Filtration Method Using the Same, and Process for Producing Said Vinylidene Fluoride Resin Hollow Filament Porous Membrane |
| abstract |
A hollow-fiber porous membrane, comprising a hollow fiber-form porous membrane in a network texture of vinylidene fluoride resin showing a pore size distribution in a direction of its membrane thickness including an outer surface-average pore size P1 as measured by a scanning electron microscope and a membrane layer-average pore size P2 as measured by half-dry method giving a ratio P1/P2 of at least 2.5. The hollow-fiber porous membrane is excellent in long-term water filtration performance including efficiency of regeneration by air scrubbing. The hollow-fiber porous membrane is produced through a process, wherein a mixture of vinylidene fluoride resin, a plasticizer and a good solvent for vinylidene fluoride resin, is melt-extruded in a hollow-fiber film and cooled and formed into a solidified film within a cooling medium containing at least a certain proportion of a good solvent for vinylidene fluoride resin. |
