POLY(ETHYLENE CHLOROTRIFLUOROETHYLENE) HOLLOW FIBER MEMBRANES AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A poly(ethylene chlorotrifluoroethylene) hollow membrane and a method for manufacturing the same are provided to treat high concentration waste water and industrial water by improving the water permeation of the membrane. CONSTITUTION: A method for manufacturing a poly(ethylene chlorotrifluoroethylene) hollow membrane includes the following: A doping solution composed of a polymer, a solvent, a pore forming agent undergoes a spinning operation, a coating operation, or a casting operation to form a membrane. The pore forming agent is extracted from the membrane. The membrane is composed of a macropore layer, an intermediate layer, and a lower layer. A plurality of cylindrical pores is formed over the entire membrane.
