Technical field

The present invention relates to nickel plating production equipment fields, and in particular to EN liquid medicine adds system automatically.

Background technique

Nickel plating solution is that the nickel ion reduction in solution is deposited on the body surface with catalytic activity with reducing agent. So far, the history of existing more than 50 years of the development of chemical nickel plating.Due to chemical Ni-plating layer have outstanding uniformity, hardness, The comprehensive physicals chemical property such as wear resisting and corrosion resistance, this technology have been used widely, and chemical stability is high, coating combines Power is good.In an atmosphere and in other media, the chemical stability of chemical Ni-plating layer is higher than the chemical stability of electroless nickel layer.

In existing production process, the control of nickel concentration is artificial sampling analysis in nickel plating bath, method particularly includes: In Nickel solution is taken out in nickel plating bath, based on nickel solution precipitation reaction, chromogenic reaction, passes through the amount of chemical equilibrium equation formula Change relationship is calculated the nickel concentration of sampling and is added in a manner of artificial supplementation after control technique concentration calculation needs increment.

The problems such as nickel solution water clock, seriously affects nickel solution when the manual analysis waste of manpower of high frequency time and artificial fluid infusion Detection and use.
