The renewal frequency of electroplating colored zinc passivation solution is not fixed, it is affected by a number of factors. The following are some of the key factors that affect the renewal frequency of electroplating colored zinc passivation solution:

Impurity concentration:

Impurity concentration: Electroplating colored zinc passivation solution has relatively poor tolerance for impurities. When the concentration of impurities (e.g. zinc ions, iron ions, copper ions, lead ions, etc.) in the passivate solution exceeds the permissible value, the passivate film may appear foggy, yellowish, etc., thus reducing the corrosion resistance of the workpiece.

Passivation solution composition and process parameters:

The composition of the passivation solution and the process parameters (e.g. passivation time, passivate temperature, pH, etc.) can also affect its service life. For example, under certain process conditions, it may be necessary to adjust the ratio of passivation solutions to suit different production requirements.

Bigely electroplating colored zinc passivation solution BZ-208 is a new high performance passivator for trivalent chrome galvanized coatings. It is a normal temperature colored zinc passivator, free of hexavalent chromium, can obtain light yellow, purple-red, bright green, yellow-green and other colors on acid zinc and alkaline zinc plating layer, to meet the appearance needs of various different workpieces.
