Electrophoresis roll type ultrafilter
Key Features
Roll-Type Membrane:
A cylindrical or roll-type membrane is used for ultrafiltration, providing a compact and efficient design.
These membranes allow selective passage of water and low-molecular-weight compounds while retaining larger particles like paint solids.
Electrophoretic Compatibility:
Optimized for electrophoresis coating baths, which involve applying paint or coating to a substrate using electrical current.
High Recovery Rate:
Recovers paint solids efficiently, reducing waste and enhancing the economy of the coating process.
Durable Material:
The ultrafilter membrane is often made from materials resistant to the harsh chemicals used in electrophoretic coating processes.
Continuous Operation:
Supports continuous filtration and recycling of the coating bath, maintaining optimal bath chemistry and reducing downtime.
