Abstract

The invention relates to the technical fields of porous ceramic materials and membrane separation, in particular to a preparation method of a shaft disc type rotary ceramic membrane. The preparation method is mainly characterized in that a microsphere ceramic raw material is selected as aggregate of a support body, ceramic fibers are selected as a transition layer, beta-silicon carbide is selectedas a membrane layer, and the shaft disc type rotary ceramic membrane is formed by pressing through a hydraulic press and firing through a low-temperature liquid phase process. The preparation methodhas the characteristics of being low in sintering temperature, low in production energy consumption, simple in process method, low in equipment requirement, low in production cost and investment cost,flexible to control, easy to form, suitable for industrial customization and capable of meeting large-scale production; and the shaft disc type rotary ceramic membrane prepared by the method has thecharacteristics of good hydrophilicity, large permeation flux, high porosity, a high yield, no need of forming a diversion trench, 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 membrane separation materials, specifically a method for preparing a shaft-disc rotating ceramic membrane. 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 permeation flux...
