[0052] Preparation method of total heat exchange membrane
[0053] The preparation method of total heat exchange membrane of the present invention comprises the following steps:
[0054] (a) providing high polymer solution or molten high polymer, said high polymer is polyvinyl alcohol, polyacrylamide, polyvinyl chloride, polyethylene glycol, polyvinylpyrrolidone, starch derivative, cellulose ether, A mixture of one or more of vegetable gums and soluble fluorocarbon polymers;
[0055] (b) mix the antibacterial additive with the high polymer solution or the molten high polymer provided in step (a) to obtain the casting solution, and the antibacterial additive is one or more of silver-loaded, copper, zinc, iron A kind of porous material, described porous material is the mixture of one or more in zeolite molecular sieve, aluminum oxide, kaolin, bentonite, montmorillonite, silica gel, metal organic framework material;
[0056] (c) forming a membrane using the casting solution obt...

[0085] 150g13X type molecular sieve and 3L concentration of 0.05mol / L AgNO 3 Mix the solutions, stir and react at 60°C for 4 hours, centrifuge after the reaction, wash with deionized water until there is no Ag in the washing liquid + , and obtained silver-loaded molecular sieves after vacuum drying, that is, antibacterial additives.
[0086] First, 20 parts of polyvinyl alcohol are dissolved in 80 parts of water to form an aqueous solution of polyvinyl alcohol; then 0.5 parts of antibacterial additives and 20 parts of anhydrous calcium chloride are added, mixed evenly, and a casting solution is formed. Using casting method, coated at 30g / m 2 1. Ordinary cellulose paper with a thickness of 100 microns is dried in an oven at 60°C to form a multi-phase solid total heat exchange film. The total heat exchange membrane can be made into a flat membrane element.
[0087] After testing, the total heat exchange membrane single-membrane carbon dioxide transmission rate prepared in thi...

[0089] 100g Y-type molecular sieve and 0.8L CuSO with a concentration of 0.15mol / L 4 Mix the solutions, stir and react at 70°C for 4 hours, centrifuge after the reaction, wash with deionized water until there is no Cu in the washing solution 2+ , after vacuum drying to obtain copper-loaded molecular sieves, that is, antibacterial additives.
[0090] First, 12 parts of polyethylene glycol are dissolved in 88 parts of water to form a polyethylene glycol aqueous solution; then 0.4 parts of antibacterial additives and 6 parts of anhydrous lithium chloride are added, mixed evenly, and a casting solution is formed. Using calendering method, coated at 20g / m 2 1. A polyester non-woven fabric with a thickness of 80 microns is dried in an oven at 40°C to form a multi-phase solid total heat exchange film. The total heat exchange membrane can be made into a hollow fiber membrane element.
[0091] After testing, the total heat exchange membrane single-membrane carbon dioxide permeation ...
