| titleOfInvention | A kind of chlorine-containing polymer base hollow fiber filtering membrane and preparation method thereof with high resistance tocrocking |
| abstract | The invention discloses a kind of chlorine-containing polymer base hollow fiber filtering membrane with high resistance tocrocking, the film have three-decker, including macropore supporting layer, dense functional layer and modified layer.Macropore supporting layer is made of chlorine-containing polymer, dense functional layer is reacted by polynary amine substance with chlorine-containing polymer, modified layer is reacted by highly resistance pollutant with polynary amine substance, structure and with stable chemical bonds between supporting layer and functional layer, functional layer and modified layer, with interpenetrating overlapping between supporting layer and functional layer.Filter membrane of the invention has the characteristics that flux is high, flux stability is good, retention and resistance tocrocking are excellent, each Coating combination is stablized in good mechanical properties, film.The present invention discloses the preparation methods of the filter membrane, and using the filming technology of immersion precipitation inversion of phases realization synchronous with interface aminating reaction, production process is simple. |
