MSK-FPI-R200 Roll-to-Roll Membrane Coating System for Hydrogen Electrolysis and Desalination
The MSK-FPI-R200 is engineered to support advanced membrane fabrication processes essential for hydrogen electrolysis and seawater desalination technologies. It enables continuous roll-to-roll processing of membrane substrates, facilitating surface modification, coating, drying, and pressing in a streamlined workflow. This system is optimized for substrates with a maximum width of 180 mm, providing precise control over coating uniformity and material properties.
The system integrates multiple functional stages including corona treatment to enhance substrate hydrophilicity, dip coating baths for hydrophobic and slurry coatings at controlled temperatures, infrared drying ovens, powder dispersion and flattening, and hot calendering with IR heating and pressure application. These processes collectively produce membranes with tailored surface and structural characteristics suitable for electrochemical and filtration applications.
Key Features
- Roller width up to 200 mm with substrate max width of 180 mm and core diameter of 3″
- Mechanical speed adjustable from 0.1 to 1.0 meters per minute for process flexibility
- Corona treatment unit delivering 2 kW power over 180 mm effective width for surface activation
- Three functional baths: two at room temperature and one heated (60-80°C) with SUS304 construction and automatic vertical movement
- Infrared drying chambers with maximum temperature up to 120°C and centrifugal fan ventilation
- Powder loading via vibration and mechanical blade flattening, followed by hot calendering with IR heating up to 150°C and maximum pressure of 10 tons
- Tension control using gas cylinder-driven swing rollers with maximum tension of 80 N and open-loop control
