Composite semipermeable membrane, spiral separation membrane element, and manufacturing method thereof |
| abstract |
PROBLEM TO BE SOLVED: To provide a composite semipermeable membrane in which water permeability is not easily lowered even when exposed to a high temperature environment for a long time, a spiral separation membrane element using the composite semipermeable membrane, and production thereof It aims to provide a method. Another object of the present invention is to provide a method for evaluating the water permeation performance of a composite semipermeable membrane, which evaluates whether the water permeability of the composite semipermeable membrane is likely to be reduced by heat by a simple evaluation method. And The composite semipermeable membrane of the present invention has a skin layer containing a polyamide resin on a porous support, and the skin layer has an elastic modulus calculated by a force curve measurement with an underwater AFM. Is 100 MPa or more. [Selection] Figure 1 |
