Manufacturing method of composite reverse osmosis membrane |
| abstract |
An object of the present invention is to provide a method for producing a composite reverse osmosis membrane which is industrially stable and continuous. The present invention is an aqueous solution containing a compound having two or more reactive amino groups on a porous support while moving the porous support in the method for producing a composite reverse osmosis membrane composed of a polyamide skin layer and a porous support supporting the same. Step A of applying a to form an aqueous solution coating layer, maintaining the aqueous solution coating layer on the porous support for 0.2 to 15 seconds, and allowing the aqueous solution a to penetrate into the pores of the porous support, the aqueous solution a into the pores of the porous support. After the step C for removing the aqueous solution coating layer and the step C, and then the step C, the organic solution b containing the polyfunctional acid halide is applied to the surface of the porous support, and the organic solution b is brought into contact with the aqueous solution a for interfacial polymerization. Process D of forming a polyamide skin layer, and continuously A method for producing a composite reverse osmosis membrane, comprising producing a composite reverse osmosis membrane. |
