Abstract
The invention discloses a preparation method of a nickel plating solution. The method comprises the steps of: 1) preparing a plating solution; 2) injecting 2/3 of water in a preliminary tank, and heating the water to 65-70 DEG C; adding the required nickel sulfate and nickel chloride, stirring to complete dissolve, adding nickel carbonate or 4% sodium hydroxide solution, and adjusting to pH value to 5.2; 3) adding 2.5 ml / l hydrogen peroxide (diluted with water) and 2.5 g / l activated carbon, stirring for a few hours to stand overnight, then filtering the plating solution into a clean plating bath; and then cleaning a filter pump, and filling the filter pump with active carbon for standby; 4) adding the required boronic acid and then adjusting the pH value of the plating solution to 4.0 by dilute sulfuric acid; 5) electrolyzing by using a wavy false cathode at a low current density for more than 12 consecutive hours, or until the low level turns from dark black to lighter gray; and 6) adding various additives.
Description
Technical field
The present invention relates to nickel-plating liquid compound method。
Background technology
By electrolysis or chemical method in the method for metal or some nonmetal plating last layer nickel, it is called nickel plating。The preparation of current nickel-plating liquid is more complicated, for some operators just entered a profession, it does not have a clear and definite method technique, causes, when operation, mistakes and omissions often occurs, in some instances it may even be possible to cause serious consequence。
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of nickel-plating liquid compound method, and this compound method is simple, join nickel-plating liquid effective, difficult drop-off when in nickel plating to metal。
For achieving the above object, the invention provides a kind of nickel-plating liquid compound method, it is characterised in that, comprise the steps, 1) plating solution preparation: include nickel sulfate 270 g/l, Nickel dichloride. 55 g/l, boric acid 43 g/l, key light agent RC-Ni8,1 mg/litre, softening agent RC-5 (4X) 10 mg/litre, adjuvant RC-1/ liter, nickel plating wetting agent 1-2 ml l, temperature is 50-60 DEG C, pH value is at 4-4.8, and electric current density is 5 amperes/square decimeter；
2) in preparation groove, inject the water of 2/3rds, add hot water to 65-70 DEG C；Adding required nickel sulfate and Nickel dichloride., stirring makes it be completely dissolved, and adds the sodium hydroxide solution of nickelous carbonate or 4%, and adjusting acid-base value is 5.2；
3) add the hydrogen peroxide (first dilute with water) of 2.5 ml l and the activated carbon of 2.5 g/l, stand after stirred for several hour the whole night, then plating solution is filtered in the electroplating bath of cleaning；Again filter pump is cleaned up, load onto activated carbon standby；
4) add required boric acid, then adjust the pH value of plating solution to 4.0 with dilute sulfuric acid；
5) with wavy false negative electrode, with low current density continuous electrolysis more than 12 hours, or until electronegative potential color is shoaled Lycoperdon polymorphum Vitt by furvous；
6) various additive is added。
The invention has the beneficial effects as follows: compound method of the present invention is simple, join nickel-plating liquid effective, difficult drop-off when in nickel plating to metal。
