Example Embodiment
[0050] Example one:
[0051] A preparation process of acid-base composite Magnet coating includes pre-treatment before plating, preparation of coating, and post-plating. The preparation of said coating is to perform potassium chloride zinc plating on the surface of the workpiece, and then zinc acid Salt galvanized. Wherein: the pretreatment before plating includes the following steps:
[0052] S11. Hang up: hang up the workpiece to the automatic production line;
[0053] S12. Degreasing: the workpieces on the automatic production line are degreasing at high temperature in degreasing liquid;
[0054] S13. Water washing I: Wash the workpiece twice with tap water;
[0055] S14. Acid electrolysis: Acid electrolysis removes the oxide film on the surface of the workpiece;
[0056] S15. Activation;
[0057] S16. Washing II: Wash the workpiece with tap water for 3 times.
[0058] The preparation of the coating includes the following steps:
[0059] S21. Potassium chloride zinc plating: potassium...
