Good Quality Aluminum Profile - Electrophoretic coating aluminum profile – Rizhaoxin Detail:
Product Description
Electro-coating of aluminum profiles is a coating method that uses an external electric field to make particles such as pigments and resins suspended in an electrophoretic solution directionally migrate and deposit on the substrate surface of one of the electrodes.
Electrophoretic coating is to put the workpiece and the corresponding electrode into the water-soluble coating, and after connecting the power supply, rely on the physical and chemical action generated by the electric field to make the resin, pigment and filler in the coating uniform on the surface of the electrode with the coating as the electrode. A coating method in which precipitation deposits form a water-insoluble paint film. Electrophoretic coating is a very complex electrochemical reaction process, including at least four processes of electrophoresis, electrodeposition, electroosmosis and electrolysis. Electrophoretic coating can be divided into anodic electrophoresis (the workpiece is anode, and the coating is anionic) and cathodic electrophoresis (the workpiece is cathode, and the coating is cationic) according to the deposition performance; according to the power supply, it can be divided into DC electrophoresis and AC electrophoresis; There are constant voltage and constant current methods. At present, the anode electrophoresis of DC power constant voltage method is widely used in industry.
The process flow is
Pre-cleaning → online → degreasing → water washing → rust removal → water washing → neutralization → water washing → phosphating → water washing → passivation → electrophoresis coating → tank cleaning → ultrafiltration water washing → drying → offline.
