Pre-treatment electrophoresis system is responsible for the front-end treatment and primer coating of the workpiece in the painting line , which is an indispensable work for the painting process. The body is the cathode, and the electrophoretic coating is cationic (positively charged). Under the action of direct current, a uniform coating film is deposited on the surface of the body. This is the basic principle of electrophoretic coating. Electrophoresis has excellent anti-corrosion and anti-rust functions.

The conventional process flow of pretreatment electrophoresis is :

Pre-cleaning → degreasing and degreasing → water washing → surface conditioning → phosphating (or silane) → water washing → pure water washing →

Electrophoresis → super filtration → pure water washing → drying

The composition of pretreatment electrophoresis :

The pre-treatment electrophoresis is composed of a tank body, filtration circulation system, automatic temperature control system, air supply and exhaust system, rectifier power supply, ultrafiltration circulation filtration system, anode circulation system, conveying system, and strong cooling chamber for electrophoresis drying .
