Method for Preparing Multichannel Ceramic Hollow Fiber Membrane
The Invention relates to a method for preparing a multichannel hollow fiber membrane. According to a certain ratio, ceramic powder, a macromolecular polymer, an organic solvent, and a dispersant are mixed evenly to prepare a membrane casting solution; and after bubble removing processing is performed on the membrane casting solution, a membrane green body is formed with the cooperation of a multichannel hollow fiber die and phase inversion. After the membrane green body is roasted at a high temperature, a multichannel ceramic hollow fiber membrane is formed. The multichannel ceramic hollow fiber membrane has an asymmetric structure and a skeleton structure in an inner cavity and can meet the strength and flux requirements of a ceramic hollow fiber membrane.
