    ABS plastic electroplate coating stripping methods

    Release date:2014-07-15 00:00 Source:http://www.choufenzi.cn Views:

    ABS plastic plating coating stripping divided into chemical and electrochemical methods, usually based on the chemical properties of the coating and the substrate is preferred, choose coating stripping methods must be aware of the following conditions:
    (A) the metal is more reactive than stripping the base metal.
    (2) may be used by a stripping of the metal complexing capacity of the base metal greater than the complexing or chelating agent, which can be reduced by stripping metal ions activity.
    (3) Withdrawal of the bath can be added inhibitor. This corrosion inhibitor can be chemically or physically adsorbed on the substrate can be blocked or completely inhibit the corrosion of the base metal in the electrolyte.
    (4) in the detached process, to control the water content of the oxidizing agent to control the degree of dissociation. Organic substances are generally added, such as glycerol, sugars, alcohols or other water-soluble organic substances.
    (5) In order to increase the stripping rate, must also contain an appropriate promoter or catalyst, such stripping is completed within a predetermined time. ABS plastic plating recovery in both the recovery of metal from the bath, but also recycled ABS plastic back, so the stripping process in ABS plastic plating, try not to damage the ABS plastic.
