Electrophoresis equipment system with the process


The electrophoresis equipment including electrophoresis tank, spray tank, electrophoresis power supply electrophoresis recovery ultrafiltration, electrophoresis coating equipment, plain, high light and color, electrophoresis equipment in most cases is mainly used for automobiles, household appliances and a variety of iron and steel parts corrosion coating. This paper describes the optional method of electrophoresis equipment and affect the coating process parameters, as follows:water filtration cartridge

The first step: we must first understand the basic process of the electrophoretic coating equipment;

Step 2: To learn electrophoretic coating equipment must have Electrophoresis Equipment Required equipment: the electrophoresis tank electrophoresis power supply (also known as the rectifier cabinet), electrophoretic oven, electrophoresis ultrafiltration machine, wash tank.

Methods and techniques of electrophoresis coating equipment:

(1) general metal surface of the electrophoretic coating, the process: pre-clean-up → Online → degreasing → ??washing → rust → washing → ??→ washing → ??phosphate → washing → passivation → electrophoretic coating → ??tank cleaning → the ultrafiltration water washing → ??drying → ??off the assembly line;

(2) of the substrate to be painted and pre-treatment has a tremendous effect on the electrophoretic coating. The castings generally use grit or shot blasting rust remove loose dust on the surface of the workpiece, cotton yarn, 80 # ~ 120 # sandpaper to remove surface residues steel shot and other debris. Steel surface degreasing and rust treatment, surface requirements too high, phosphating and passivation surface treatment;bag filters

(3) Usually, in the filtration system, using a filter, the filter a mesh bag structure, a pore size of 25 to 75 microns. Electrophoretic paint through the vertical pump fed to the filter to filter;

(4) The size of the amount of the circulatory system of the electrophoresis equipment coating cycle, a direct impact on the stability of the bath and the quality of the film. To increase the amount of circulation, precipitation and air bubbles of the bath to reduce; bath accelerate the aging of the increase in energy consumption, deterioration of the stability of the bath;

(5) With the extension of production time, the impedance of the anode separator will increase the effective working voltage drop
