Pervaporation ceramic membrane

Author:


Pervaporation ceramic membrane is a silicon aluminate crystal with a regular microporous structure. In addition to the advantages of general inorganic membranes, it also inherits the characteristics of molecular sieves, and its uniform pore size distribution provides good selectivity and adsorption performance; The interconnected pore structure in three-dimensional space enables rapid gas diffusion; Zeolite intergranular pores can be modified to enhance their selective adsorption properties. Pervaporation ceramic membranes have become very promising membrane materials.
Compared with pervaporation organic membranes, molecular sieve membranes have the advantages of high temperature resistance, chemical corrosion resistance, high mechanical strength, high flux, high separation coefficient, no swelling problem of organic membranes, and long service life of membranes. No vacuum hood is required, and the equipment occupies a small area for easy installation and maintenance.
