Definitions
- the invention has for its object to provide a method and an apparatus for performing this method, with or with the time and effort of the bathroom cleaning with permanent guarantee of constant good bath quality and minimal use of chemicals can be reduced.
- the invention relates to a process for depositing functional layers from acidic or alkaline zinc or zinc alloy baths, the organic additives selected from brighteners, wetting agents and complexing agents, a soluble zinc salt and optionally further metal salts selected from Fe, Ni, Co, Containing Sn salts comprising the following steps:
- the solid phase can be separated by means of a crystallizer.
- a crystallizer Such systems for the separation of crystalline impurities from electroplating baths are known from the prior art and described for example in US 5,376,256. Commercially, such a system is available from USFilter under the name CARBOLUX.
- phase separation is achieved by addition of preferably solid sodium hydroxide, with a concentration greater than 200 g / l of sodium hydroxide being advantageous.
- the separation unit (3 1 ) comprised a crystallizer from Carbolux.
