摘要：NOVELTY - A three-channel ultrafiltration membrane is prepared by utilizing polyether sulfone or polysulfone as the polymer material, N,N-dimethyl acetamide as solvent, diethylene glycol as additive to prepare casting solution. The casting solution is electrically stirred for 20-24 hours, kept aside and de-foamed for 20-24 hours, where the core liquid flow speed is 15-21 ml/minute, the take-up speed is 3.0-4.0 m/minutes, an air distance is 0-2 cm and the coagulation bath temperature is 20-25 degrees C. USE - Three-channel ultrafiltration membrane. ADVANTAGE - The three-channel ultrafiltration membrane can be prepared with high chlorine resistance, and effectively expanding the selection range of the base film has obvious industrial practical application value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing three-channel ultrafiltration membrane.
