[China Aluminum] leakage plating is sometimes encountered in hot-dip galvanizing, and there are 10 ways to solve hot-dip galvanizing leakage plating:
1. Strengthen the pre-treatment of hot-dip galvanizing 2. Minimize the dwell time of the process 3. Ensure the quality concentration and reasonable ratio of the plating agent 4. Prevent the overheating and burning of the plating agent 5. The content of aluminum in the zinc liquid is controlled Below 0.05%, it is recommended to use 5-10% of the aluminum content of the intermediate alloy, not directly using pure aluminum ingots.
6. Keep the surface of the hot dip galvanized zinc liquid at the entrance of the workpiece clean and prevent the aluminum content from being enriched.
7. Avoid high-carbon steel pickling 8. Thoroughly remove welding slag and slag spatter. 9. Remove any residual matte after grinding off the surface of the flame cutting area.
10. Pre-spray a high concentration of solvent where hot-dip galvanizing is likely to result.
