Embodiment 1
[0050] Prepare 1000L steel batch hot-dip galvanizing environment-friendly multi-effect auxiliary plating solution, which is used for the auxiliary plating process before batch hot-dip galvanizing of steel parts.
[0051] Take zinc phytate 200kg, zinc bromide 50kg, sodium chloride 50kg, manganese chloride 25kg, potassium fluoroaluminate 75kg, tartaric acid 25kg, gallic acid 5kg, perfluoroalkyl ether quaternary ammonium salt cationic surfactant 8kg, balance for water. The 500mm long 50×50×5 angle steel is immersed in the plating flux solution after degreasing→water washing→pickling→water washing. The temperature is controlled at 60°C, the pH value is controlled at 5, and the fluxing time is 6 minutes. The angle steel after galvanizing is quickly dried within 3 to 4 minutes, and hot-dip galvanizing is carried out without drying. When the angle steel is immersed in the zinc solution, there is no zinc explosion, the zinc dust is reduced by nearly two-thirds, and the zinc fume is mi...
Embodiment 2
[0053] Prepare 1000L steel batch hot-dip galvanizing environment-friendly multi-effect auxiliary plating solution for batch of steel parts
[0054] Flux plating process for pre-treatment of calorimetric hot-dip galvanizing.
[0055] Take zinc bromide 200kg, zinc chloride 100kg, magnesium chloride 50kg, sodium chloride 50kg, bismuth chloride 20kg, potassium chloride 100kg, tartaric acid 35kg, phytic acid 5kg, phosphoric acid 5kg, octadecyltrimethylammonium chloride 3kg , coconut oil fatty acid diethanolamide 6kg, surplus is water. A 500mm long 50×50×5 angle steel is immersed in the plating flux after degreasing→water washing→pickling→water washing. The temperature is controlled at 50°C, the pH value is controlled at 3.5, and the fluxing time is 3 minutes. The angle steel after galvanizing is quickly dried within 3 to 4 minutes, and hot-dip galvanizing is carried out without drying. When the angle steel is immersed in the zinc solution, there is no zinc explosion, the zinc dust...
Embodiment 3
[0057] Prepare 1000L steel batch hot-dip galvanizing environment-friendly multi-effect auxiliary plating solution for batch of steel parts
[0058] Flux plating process for pre-treatment of calorimetric hot-dip galvanizing.
[0059] Take zinc phytate 250kg, zinc bromide 50kg, ammonium acetate 50kg, sodium chloride 100kg, barium chloride 25kg, potassium fluoride 75kg, tartaric acid 40kg, phytic acid 5kg, phosphoric acid 5kg, perfluoroalkyl ether quaternary ammonium salt cationic surface Active agent 4kg, coconut oil fatty acid diethanolamide 6kg, balance is water. A 500mm long 50×50×5 angle steel is immersed in the plating flux after degreasing→water washing→pickling→water washing. The temperature is controlled at 55°C, the pH value is controlled at 4, and the fluxing time is 5 minutes. The angle steel after galvanizing is quickly dried within 3 to 4 minutes, and hot-dip galvanizing is carried out without drying. When the angle steel is immersed in the zinc solution, there is ...
