Title:
A continuous production method of the support ion selectivity film based on a water solvent
Document Type and Number:
Japanese Patent JP6188821
Kind Code:
B2
Abstract:
An apparatus for manufacturing membranes is provided, the apparatus comprises a casting section, a processing section and a conveyor system. The casting section prepares a membrane that is conveyed to the processing section. The conveyor system conveys the membrane through the processing section. In the processing section, the membrane is conditioned in tanks to extract residues. The membrane is also subjected to a leak test to detect physical flaws in the membrane. The leak test involves applying a dye to a surface of the membrane. Any dye that leaks through the membrane will provide a high contrast dye mark on an adjacent contrast material, which is indicative of a physical flaw in the membrane. A process for manufacturing and testing membranes is also provided. The process comprises the steps of casting a membrane precursor, curing the membrane precursor to form a membrane and processing the membrane.
