| Abstract: | A kind of originally created unique ternary additive of spinning solution and corresponding dry-jet wet-spinning membrane fabricating conditions were invented. The hollow fiber ultrafiltration membrane developed has high permeability, no defect, narrow differential pore size distribution and excellent retentity. The membrane have double-row finger-like pore support layer structure and have skins both on the inner surface and on the outer surface, so the hollow fiber membrane can be operated under inside pressure or outside pressure. A series of hollow fiber ultrafiltration membranes with molecular weight cut-off of 10000; 30000; 50000 and 100000 respectively. |
