Enviolet~R-UV-Oxidation: A Proven Method for Bright-Nickel Plating Bath Purification

摘要

At Hansgrohe, the goal for permanently achieving a consistent and optimal bright-nickel deposit was realized. However, the biggest savings potential is in the improved utilization of the organic brightener additives. As demonstrated by the customer, the organic brightener additive concentration can be significantly increased in the nickel bath, which enormously reduces the cost of the mechanical pretreatment (grinding, polishing/buffing) steps. Plating bath purification with the Enviolet~R-UV-Oxidation method has now been proven for many years in various operations. Hansgrohe in particular has proven that this technology works remarkably well and has been depending solely on this plating bath maintenance process with no additional purification concepts. Furthermore, a.c.k. has gained considerable experience since the beginning, and has improved the process even further. The UV evaporator system was developed, which has a significant impact for the plating bath purification process, as it allows the reclaiming of rinse water dragout back into the plating bath. This further improves the economics of the system operation. This treatment concept has already been proven in many printed circuit board (PCB) manufacturing companies worldwide.
