| titleOfInvention | The preparation method of long-acting hydrophilic polyvinyl chloride hollow fiber ultrafiltration membrane |
| abstract | The preparation method that the invention discloses a kind of long-acting hydrophilic polyvinyl chloride hollow fiber ultrafiltration membrane, belong to optimal experimental design technical field, by hydrophilic high molecular polymer with polychloroethylene blended, solution inversion of phases film forming procedure realizes the purpose of long-acting hydrophilic modification. Preparation method is as follows: polrvinyl chloride, long-acting hydrophilizing agent, pore former, heat stabilizer and solvent are mixed in proportion, obtain the hollow fiber ultrafiltration membrane casting solution that polrvinyl chloride mass concentration is 8-30%, by this casting solution with inner gel medium simultaneously by spinneret extrusion tubulose liquid film, this liquid film enters in outer setting medium through the airspace of 0-30 centimetre and solidifies, prepared long-acting hydrophilic through rinsing, that flux is big, flux decline is little, intensity is high, rejection effect is good PVC hollow fiber ultrafiltration membrane. |
