Abstract

PURPOSE: To prevent the discoloration and staining during plating and obtain a titled steel plate of superior surface appearance by subjecting the steel plate to a wetting treatment with an aq. alkaline or acidic soln. of specific pH after electric zinc plating.
CONSTITUTION: After zinc type plating is applied on both or one surface of a pretreated steel plate, the surfaces of the steel plate are wetted with an aq. alkaline soln. of ≥12pH or an aq. acidic soln. of ≤2.5pH. The composition and temp. of these aq. solns. are not particularly limited. The method of wetting is not particularly limited, and the treatment time can be selected as desired according to the degrees of discoloration and staining of the plated and non-plated surfaces. Usually it may be as short as several seconds or less. After the wetting process, a washing process such as rinsing, hot rinsing or the like is processary.
