Abstract

The invention relates to the technical field of porous ceramic materials and membrane separation, and in particular relates to a preparation method of a shaft disk type rotating ceramic support body.The shaft disk type rotating ceramic support body is mainly characterized in that a shaft disk type rotary ceramic support body is formed by selecting microsphere ceramic raw materials, pressing and forming by a hydraulic press and firing by a low-temperature liquid phase method. The preparation method has the characteristics of low sintering temperature, low production energy consumption, simpleprocess method, low equipment requirements, low production cost and investment cost, flexible control, easy molding, suitability for industrial customization, and satisfaction of large-scale production. The shaft disk type rotary ceramic support body produced by the method has the characteristics of good hydrophilicity, super-large permeation flux, high porosity, high yield, no need of a guide groove, good acid and alkali resistance and long service life.

Description

technical field [0001] The patent of the present invention relates to the technical field of inorganic porous materials, in particular to the technical field of inorganic ceramic membrane separation materials, specifically a method for preparing a shaft-disc rotating ceramic support. Background technique [0002] Compared with traditional polymer separation membrane materials, ceramic membranes have the advantages of good chemical stability, acid and alkali resistance, organic solvent resistance, high mechanical strength, backwashing, strong anti-microbial ability, high temperature resistance, narrow pore size distribution and high separation efficiency. , It has been widely used in the fields of food industry, biological engineering, environmental engineering, chemical industry, petrochemical industry and metallurgical industry. [0003] However, ceramic membranes also have the problem of membrane fouling, resulting in a series of disadvantages such as low membrane permeati...
