After pickling, water cleaning, squeeze dry, drying, into the zinc pot, the temperature has been maintained at 445-465℃.

When the large roll galvanized wire galvanizing process coating foaming, first check the bath temperature. If the bath temperature is not low, then strengthen the plating before removing oil, prevent the matrix metal in acid corrosion. If you pay attention to these problems, the foaming phenomenon still exists, it should pay attention to the amount and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, in order to reduce the content of additives, observe whether the foaming phenomenon is improved. If there is still no improvement, it is necessary to check whether the storage period of additives is too long, or whether there are too many impurities in the additives.
