Abstract

The invention discloses polyethylene out-phase ion interchanging film for filled bed electricity oozing salt eliminating device and the manufacturing method. The film comprises: high pressure polyethylene 100, linear high pressure polyethylene 18í½30, chlorine sulphur polyethylene 2í½5, cinnamene-butadiene-cinnamene polymer 3.1í½3.8, polybutylene 15í½30, calcium stearate 5í½8, antioxidant 0.5í½1.5, positive or negative ion interchanging resin power 370í½480. The film combines several kinds of plastic as frame, adds the power into the plastic and rolls them and extracts out the film. Enhances them by terylene cloth, finally, carries on hydraulic pressure and heat pressure.

Description

(1) Technical field [0001] The invention relates to an ion exchange membrane for producing ultrapure water, in particular to a polyethylene heterogeneous ion exchange membrane for a packed bed electrodialysis desalter and a preparation method thereof. (2) Background technology [0002] The use of ion exchange membranes to manufacture electrodialyzers has been used for seawater desalination, boiler water preparation, ion separation and concentration, etc. for decades, but the ion exchange membranes produced in the past have poor compactness and low mechanical strength. Low, oxidation resistance and corrosion resistance are also poor. [0003] EDI continuous electric desalter, also known as packed bed electrodialysis water purifier (ElectrodeioniZation), is a green production equipment with no environmental pollution being promoted in the world. This production process combines electrodialysis technology and ion exchange technology without acid and alkali treatment. Produce u...
