Pretreatment is the basis of the coating process and has a great influence on the quality of the coating. Pretreatment includes major processes such as degreasing, pickling, surface conditioning, and phosphating. Degreasing is the basis of the foundation, and the cleanliness of the surface of the workpiece directly affects the quality of subsequent processes. Pickling is mainly used to clean the scale of hot-rolled steel sheets. It is mainly used for the cleaning of frames and wheels in automotive painting. Pickling can seriously pollute the workshop environment, and should not be used instead of shot blasting. The phosphating process can improve the adhesion of the surface of the workpiece and also improve the corrosion resistance of the electrophoretic layer.

Electro-ice coating is to immerse a metal workpiece in an electrophoretic coating solution as a cathode (or anode). A corresponding anode (or cathode) is arranged in the slot, and the two poles pass through the direct current, and A coating method for depositing a uniform, water-insoluble coating on the surface of the workpiece.
Electrophoretic coating is divided into two methods: cathodic electrophoresis and anodic electrophoresis: the workpiece is a cathode, and the coating is Old ionic type (with positive charge), called cathodic electrophoresis; workpiece is anode, paint is yin Ionic (negatively charged) is called anodic electrophoresis. |

Create maximum value for success
Electrophoresis characteristics and advantages 1, strong swimming penetration. It can weld the weld and the inner cavity of the workpiece with complicated shape, and apply the film on the dead angle swimming. Greatly improve the life of the workpiece. 2. The coating film has strong adhesion and high corrosion resistance. The coating film of cathodic electrophoresis is resistant to salt spray for more than 1000 h. 3. High utilization rate of paint. After electrophoresis, the ultrafiltration (UF) solution is used to rinse the electrophoresis tank. The coating on the surface of the part returns to the electrophoresis tank, and the utilization rate can reach over 95%. 4. The coating film is fine and uniform. 5, suitable for large-scale production, continuous flow operation, and can achieve automated production. |
