Ultrafiltration Membranes for Electrophoretic Paint

Working Principle: 






The ultrafiltration membrane module for electrophoretic paint utilizes polypropylene (PP) hollow fiber membranes to achieve separation through external pressure crossflow filtration. The feed fluid is pressurized on the outer surface of the membrane, allowing liquid to pass through the membrane pores (0.02–0.1 μm) into the interior, retaining macromolecules, resins, and pigments for purification and concentration.




Features of Ultrafiltration Membranes for Electrophoretic Paint:




Superior Membrane Material: Made from polypropylene (PP), offering excellent chemical stability and corrosion resistance, suitable for a wide pH range (0-14).

High Flux and Retention Rate: Pure water permeability ≥1000 L/h (at 0.1 MPa and 25°C), with a retention rate for resins and pigments ≥99%.

Structural Design: The component is designed for external pressure, facilitating installation and cleaning, with up to 15,000 fiber strands providing a large membrane area (>12 m²).

Durability: Can withstand short-term exposure to chlorine (100 ppm) and hydrogen peroxide (200 ppm), with a maximum pressure tolerance of 0.15 MPa.

Flexible Installation and Operation: Can be installed vertically or horizontally, supporting crossflow filtration to reduce membrane clogging risk.

Long Service Life: Optimized design reduces sedimentation and fouling, making cleaning easy and maintenance straightforward.





Applications:



Electrophoretic Paint Production: Used for ultrafiltration and purification of electrophoretic coatings, enhancing the purity and quality of the coatings.

Biopharmaceuticals: Suitable for removing and concentrating cells, viruses, and bacteria during biopharmaceutical processes.

Water Treatment: Effective in industrial wastewater treatment, removing suspended solids and organic matter.
