Pre-treatment/Elecrocoating Plant


Pre-treatment is the foundation of coating project, which has a great influence on the quality of coating. Pre-treatment includes degreasing, pickling, surface conditioning, phosphating and other main processes. Among them, degreasing is the foundation of the foundation, the cleanliness of the surface of the workpiece directly affects the quality of the subsequent processes. Pickling is mainly used to clean the oxidised skin of hot rolled steel plate, and it is mainly used to clean the frame and wheels in automobile coating. Acid washing will seriously pollute the workshop environment, should try not to use shot blasting instead. Phosphating process can improve the surface adhesion of the workpiece and also improve the corrosion resistance of the electrophoretic layer.
