Tubular Anode Cell for Electrocoating Systems

Overview
Anode Cells, also known as Anolyte Cells, are critical components in cathodic electrophoretic coating (e-coating) systems. They are used to isolate the anode from the paint bath while allowing ions to pass through a selective membrane. This ensures consistent bath quality and improves the durability and appearance of the final coating.

Working Principle
The Anode Cell consists of an internal titanium anode and an ion-exchange membrane. When a DC voltage is applied, positively charged ions (such as amines and other counter-ions from the e-coating bath) migrate through the membrane into the anolyte solution. This process:

• Maintains the bath's pH balance
• Improves paint stability
• Reduces contamination and paint defects

Specifications

Key Features

• Membrane Material: High chemical resistance, excellent ion-selective permeability
• Electrode: Stainless steel with long service life
• Anolyte Circulation System: Ensures efficient ion removal and heat dissipation
• Leak-Proof Design: Ensures safe operation and prevents cross-contamination

Advantages

• We use high quality anion exchange membrane sheet.
• We use integrated high strength inner support with high porosity.
• More open area = less resistance = more usable anode surface area = Better Efficiency.

Applications

• Automotive components
• Home appliances
• Agricultural and construction machinery
• Steel furniture and metal parts finishing
