Abstract
The invention discloses a ceramic filter membrane preparation method and a ceramic filter membrane, which relate to the technical field of filter materials, and aims to solve the technical problem ofpoor structural stability of the ceramic filter membrane in the prior art. The preparation method of the ceramic filter membrane comprises the following steps: sintering a ceramic membrane raw material at a preset temperature for a preset time to form slurry; injecting the slurry into a mold, and adding a second binder; after the slurry reaches the preset hardness, performing demolding, and obtaining a blank body; coating the surface of the blank body with a membrane preparation solution for multiple times until the membrane preparation solution is uniformly distributed on the surface of theblank body, and after the blank body coated with the membrane preparation solution is dried, putting the blank body coated with the membrane preparation solution into a sintering furnace for sinteringto obtain the ceramic filter membrane. Therefore, the ceramic filter membrane generated by the invention is relatively good in structural stability.
Description
Technical field [0001] This application relates to the technical field of filter materials, and specifically to a method for preparing a ceramic filter membrane and a ceramic filter membrane. Background technique [0002] At present, the main preparation techniques of inorganic ceramic membranes are: sol-gel method, solid particle sintering method, phase separation method, chemical vapor deposition method, physical vapor deposition method, etc. Currently, porous membranes are mainly ultrafiltration and microfiltration membranes, and their preparation methods are mainly particle sintering and sol-gel methods. [0003] In the prior art, the ceramic membrane has a complicated manufacturing process, high cost, and high price; in addition, the ceramic membrane in the prior art only has an outer layer and a support layer, which has poor structural stability, low membrane flux, and poor filtration effect. good. Summary of the invention [0004] The purpose of this application is to provi...
