Abstract

Belonging to the technical field of membrane separation, the invention provides an automatic assembling device and method of a multilayer composite separation membrane. Existing composite membranes prepared by an immersion layer-by-layer self-assembly method has the problems of a lot of composite layers, long film forming cycle, and complex procedures, and is not conducive to industrial production. The automatic assembling device and method of a multilayer composite separation membrane can respectively spray membrane making liquids of different components to the surface of a porous support body in order. And then through layer-by-layer reaction on the surface and assembly, the multilayer composite separation membrane can be formed. The automatic assembling device and method of a multilayer composite separation membrane in the invention can automatically complete spraying and assembly of membrane making liquids with different components, effectively overcome the complicated steps in existing self-assembly membrane forming processes, substantially shorten membrane forming time, and can be adapted to the demands of large scale production.

Description

technical field

[0001] The invention relates to an automatic assembly device and method for a multilayer composite separation membrane, belonging to the technical field of membrane separation. Background technique

[0002] Polyelectrolyte, also known as polymer electrolyte, refers to a polymer with many ionizable ionic groups in the main chain or side chain. Polyelectrolytes are widely used in the fields of flocculants, dispersants, superabsorbent resins, biomedicine and membrane materials because of their charge and most of them have good hydrophilicity. Polyelectrolytes can be divided into polycations, polyanions and amphoteric polyion electrolytes with positive and negative charges according to their charges. The polyelectrolyte composite membrane can be formed by the electrostatic force between two oppositely charged polyelectrolytes, by hydrogen bonds and hydrophobic interactions, or by the coordination between a polyelectrolyte and inorganic metal ions or small organi...
