Abstract

The invention discloses a process of prolonging service life of a chemical nickel-plating liquid product, and relates to the production technical field of the chemical nickel-plating liquid product. The process is as follows: (1), respectively placing a cathode rod and an anode rod into bath liquor when a nickel bath is under a non-working state; (2), carrying out electrolysis by using 0.5 ASD small current for mainly separating out impurity ions such as Fe<3+>, Cu<2+> in the nickel bath at a cathode in the form of elementary substances; and (3), stopping the electrolysis when bath liquor works. The process disclosed by the invention is simple in process step and easy to realize, lowers cost and maximizes the corporate profits.

Description

The technique in prolongationization nickel liquid medicine life-span
Technical field
The production technical field of the present invention relates to nickel liquid medicine, is specifically related to the prolongationization nickel technique in liquid medicine life-span.
Background technology
At present, in the product of chemical nickel plating, mainly comprise low-phosphorous, middle phosphorus, high-phosphorus chemical nickel both at home and abroad.And the cycle of general low-phosphorous chemical nickel is 5~6MTO, the cycle of middle phosphorus chemistry nickel is 3~4MTO, and the cycle of high-phosphorus chemical nickel is 7~8MTO.Under the prerequisite of all intending in guaranteed quality in current Ge Jia enterprise, reduce costs to greatest extent to the greatest extent, realize under the maximized prerequisite of enterprise profit, and the cycle of current all kinds ofization nickel liquid medicine is generally shorter, is unfavorable for the reduction of cost.
Summary of the invention
The object of this invention is to provide the prolongationization nickel technique in liquid medicine life-span, its processing step is simple, is easy to realize, and has reduced cost, has realized the maximization of enterprise profit.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: its technique is as follows: 1,, when nickel groove is under off working state, cathode bar and anode bar are put into respectively to tank liquor;
2, carry out electrolysis with the little electric current of 0.5ASD, be mainly by the foreign ion in nickel groove as Fe3+ Cu2+ etc., be allowed to condition at negative electrode to separate out with the form of simple substance;
3 until tank liquor when work stop electrolysis.
Principle of work of the present invention: by extending the cycle of chemical nickel plating liquid medicine, and the quality of guaranteeization nickel product, thereby reach the requirement that reduces enterprise cost.
The present invention has following beneficial effect: its processing step is simple, is easy to realize, and has reduced cost, has realized the maximization of enterprise profit.
Embodiment:
This embodiment is by the following technical solutions: the technique that it comprises is as follows: 1,, when nickel groove is under off working state, cathode bar and anode bar are put into respectively to tank liquor;
3, carry out electrolysis with the little electric current of 0.5ASD, be mainly by the foreign ion in nickel groove as Fe3+ Cu2+ etc., be allowed to condition at negative electrode to separate out with the form of simple substance;
4 until tank liquor when work stop electrolysis.
This embodiment is by extending the cycle of chemical nickel plating liquid medicine, and the quality of guaranteeization nickel product, thereby reaches the requirement that reduces enterprise cost.
This embodiment processing step is simple, is easy to realize, and has reduced cost, has realized the maximization of enterprise profit.
Embodiment:
Embodiment mono-:
In the time changing nickel tank liquor and quit work, carry out electrolysis with the little electric current of 0.5ASD, when production, stop electrolysis, production process all repeats this operation at every turn.The final life-span of finding this liquid medicine reaches 7~8MTO, and phosphorus content is in 4% left and right, hardness, and wear-resistant degree, weldability is conformance with standard all.
Embodiment bis-:
In the time changing nickel tank liquor and quit work, carry out electrolysis with the little electric current of 0.5ASD, when production, stop electrolysis, production process all repeats this operation at every turn.The final life-span of finding this liquid medicine reaches 5~6MTO, and phosphorus content is in 7% left and right, hardness, and wear-resistant degree, weldability is conformance with standard all.
Embodiment tri-:
In the time changing nickel tank liquor and quit work, carry out electrolysis with the little electric current of 0.5ASD, when production, stop electrolysis, production process all repeats this operation at every turn.The final life-span of finding this liquid medicine reaches 9~10MTO, and phosphorus content is in 11% left and right, corrosion-resistant degree, hardness, and wear-resistant degree, weldability is conformance with standard all.
