MSK-AFA-C300-CHGD Roll-to-Roll Membrane Coating System with Phase-Inversion Water Baths for Hydrophilic Surface Treatment and Membrane Fabrication
The MSK-AFA-C300-CHGD is engineered for precise roll-to-roll coating of membranes, particularly suited for applications such as hydrogen electrolysis and seawater desalination. This system facilitates continuous substrate processing, enabling the transformation of raw materials into functional membranes with hydrophilic surfaces and hydrophobic coatings through a controlled phase-inversion process.
The substrate unwinds from a roller and passes through a blade film applicator or optional slot-die coater to achieve a hydrophilic surface. Subsequently, it undergoes dip coating in multiple temperature-controlled water baths containing hydrophobic repellents at room temperature. The coated membrane is then dried in a convection or infrared heated chamber with a maximum temperature of 150°C before entering a washing bath at ambient conditions to complete the fabrication cycle.
