热镀锡铁皮生产中的白酸洗,是光亮退火后冷轧铁皮热镀锡不可缺少的一个工序。它能保证良好地去掉镀锡前原板表面上的氧化铁皮,锡能与纯净的铁基体牢固地结合起来。我厂热镀锡机组中的白酸洗是採用了世界上最先进的工艺——工业周波交流电非接触法电解酸洗。该方法,目前国外仅在实验中获得了成功,很少应用在工业性生产中。目前国内
White pickling in the production of hot-tin sheet metal is an indispensable process for the hot-tinning of cold-rolled tin sheets after bright annealing. It ensures a good removal of the scale on the surface of the original plate before tin plating, and the tin can be firmly bonded to the pure iron matrix. Our factory white tinned hot tin is used in the world’s most advanced technology - industrial frequency AC non-contact electrolytic pickling. The method, currently only successful in foreign experiments, rarely used in industrial production. At present
