When we use alkaline galvanizing brighteners, why is the plating solution contaminated with chloride ions? In this issue, we will analyze how chlorine ions come about.
①Inadequate cleaning before plating
This is its main introduction pathway. Strong corrosion and activation of iron and steel parts before plating, so far, most of the hydrochloric acid is still used, and industrialized production, often cleaning before plating is not thorough, not to mention the flow of pure water cleaning. As a result, not only to the plating solution into the introduction of divalent iron ions, but also a large number of chloride ions.
② High chlorine content in city tap water
City water in the treatment, pretreatment for the removal of suspended solids, often add alkaline aluminum chloride and so on for flocculation; and in the elimination of du and often use chlorine disinfectants and so on to kill E. coli and so on.
Therefore, when customers use Bigely alkaline galvanizing brightener BZ-518, our engineers teach them how to deal with it when there is an excess of chloride ions in the plating solution, so as to ensure that the plating layer is of normal quality and can be delivered to the downstream customers in time.
