| titleOfInvention | A kind of PVA-PVDF hollow fiber ultrafiltration membrane, preparation method, preparation facilities and application |
| abstract | The present invention relates to a kind of preparation methods of small-bore organic hollow fiber ultrafiltration composite membrane, using narrow slit blade coating as main feature, first controllably in one layer of PVA solution of PVDF doughnut coating on base films, while PVA further being promoted more uniformly to sprawl and adhere on surface.The present invention has following benefit: (1) the average pore size control problem of composite membrane, it is made to can be applied to certain a kind of specific system；(2) film thickness is controlled, makes the existing good integrality of composite membrane, ideal permeability can be possessed again；(3) the narrow slit coating processes of blocking operation are convenient to industrialization amplification. |
