Claims preview

1 . An apparatus for manufacturing a composite deionization electrode, comprising: two polymer sheet supply units, each configured to supply a respective polymer sheet; two polymer sheet impregnation units, each comprising a tank containing an ion exchange solution and configured to impregnate the polymer sheet supplied from a corresponding polymer sheet supply unit with the ion exchange solution; an electrode sheet supply unit configured to supply a carbon electrode sheet; an undercoating unit comprising a first laminating roller and a second laminating roller that are sequentially disposed in a vertical direction, the undercoating unit being arranged to laminate each of the two polymer sheets on a respective one of the opposite surfaces of the carbon electrode sheet supplied from the electrode sheet supply unit to form a first composite; a top coating unit comprising a tank containing an ion exchange solution configured to coat both surfaces of the first composite with the ion exchange solution from the tank of the top coating unit to produce a second composite; and a drying unit configured to dry the second composite; wherein the carbon electrode sheet is supplied between the two polymer sheets through the undercoating unit, and the two polymer sheets and the carbon electrode sheet pass and are laminated through the first laminating roller and the second laminating roller. 2 . The apparatus for manufacturing the composite deionization electrode of claim 1 , further comprising a surface treatment unit configured to surface treat the polymer sheet supplied from the polymer sheet supply unit using corona discharge or plasma. 3 . The apparatus for manufacturing the composite deionization electrode of claim 1 , wherein the polymer sheet is a porous polymer sheet.
