| titleOfInvention | A kind of hollow fiber nanofiltration membrane and preparation method thereof |
| abstract | A kind of hollow fiber nanofiltration membrane and preparation method thereof, the NF membrane are made up of polymeric material internal layer, polymeric material outer layer and the intermediate layer that is mutually wound by the strand of internal layer and outer layer copolymer material.Its preparation method is that inner layer polymeric material and outer layer copolymer material are dissolved in high-temperature diluent, using two parallel dual-screw extruding machines and triple channel spinning head；The step of method one for causing to be separated by temperature or exchange of solvent obtains the internal layer and nano pore structure outer layer of co-continuous pore passage structure, that is, obtains hollow fiber nanofiltration membrane.The present invention possesses the features such as high intensity, resistance to backwash, high selection separating property. |
