Description
Technical field
The present invention relates to the technical field of the liquid making method that works, especially a kind of pre-electroplating treatment work liquid making method.
Background technology
With the fast development of social economy, people also increasingly pursue the quality of life.Plating be more widely applied come into industrial production, with advancing by leaps and bounds for electroplating industry, constantly expand with development, thereupon to the people, to community, it is also increasingly severe to the pollution of environment, strong acid, highly basic are exactly one of very serious pollution sources.
However, the concentrated sulfuric acid as pre-electroplating treatment oil removing, scale removal, membrane removal history for a long time, due to cheap, oil removing, scale removal, membrane removal effect is good and enjoys the favor of vast Electroplate Factory.But there is also many deficiencies using the concentrated sulfuric acid as the working solution of pre-electroplating treatment：(1) dangerous to operating personnel high, the accident of concentrated sulfuric acid burn operating personnel happens occasionally；(2) penetrating odor is big, causes production environment, air quality inferior；(3) cost for wastewater treatment is high, and water for cleaning usage amount is big, heighten PH to 2.0 and need the piece alkali of 18~30g the normal waste water 1L using the concentrated sulfuric acid, therefore many electroplating enterprises do not make that any treatment is just in line or the row of stealing to this waste water；(4) big is damaged to spring product production, frequently results in elastic force and weaken or even disappear；(5) it is complicated to deep hole, deep trouth, cleaning dirty production；(6) corrosivity is big, big to workpiece corrosion, causes back segment electroplating bright copper, the high cost of bright nickel；(7) often there is plating bubble problem.
The content of the invention
The technical problem to be solved in the present invention is：In order in solving the problems, such as the prior art in above-mentioned background technology, there is provided a kind of pre-electroplating treatment work liquid making method of replacement concentrated sulfuric acid.
The technical solution adopted for the present invention to solve the technical problems is：A kind of pre-electroplating treatment work liquid making method, specific preparation steps are as follows：
A, inject water in a reservoir first；
B, it is subsequently adding hypochlorous acid；
C, add hydrofluoric acid；
D, add citric acid；
E, add potassium sulfide；
F, add op-10；
G, add hydrochlorate；
H, water is eventually adding, stirred.
The beneficial effects of the invention are as follows：A kind of pre-electroplating treatment work liquid making method of the invention, preparation steps very simple, obtained liquid can effectively replace use the concentrated sulfuric acid as membrane removal, oil removing, the pre-electroplating treatment of scale removal working solution, various compositions are mixed, corresponding effect is brought it about, it is easy to use to reach the best combination of workpiece and electrodeposited coating, accomplish to improve product percent of pass, applicability is wide.
Specific embodiment
A kind of pre-electroplating treatment work liquid making method of the present invention, specific preparation steps are as follows：
A, inject water in a reservoir first；
B, it is subsequently adding hypochlorous acid；
C, add hydrofluoric acid；
D, add citric acid；
E, add potassium sulfide；
F, add op-10；
G, add hydrochlorate；
H, water is eventually adding, stirred.
The effect of various compositions is as follows in the formula of this working solution：
Workpiece and workpiece are dissected first to plating demand：Have currently on the market and most of pieced together or be welded by alloys such as kirsite or kirsite and copper, iron, tin.And kirsite is made up of zinc, aluminium, copper, magnesium, cadmium, titanium, iron etc. in itself.According to the characteristic of above Conventional alloys, various composition consumptions are adjusted in right amount.
Hypochlorous effect：Light corrosion is played workpiece surface.
The effect of hydrofluoric acid：Aluminium to the workpiece of surface richness aluminium phase carries out corrosion branch except treatment, to strengthen electrodeposited coating conjugation.
The effect of op-10：To workpiece surface in each process once purged greasy dirt clean not yet into decomposing after working solution, to keep the clean of working solution.
Sulfuric acid corrodes to zinc, when sulfuric acid and zinc react, accelerates to workpiece surface greasy dirt, the stripping of oxide-film, while suitably increase the roughening degree of workpiece surface, to increase plating adhesion.
Below by taking the working solution for preparing 20L as an example, specific preparation steps are as follows：
A1, the water for injecting 10L in a reservoir first；
B1, the hypochlorous acid for being subsequently adding 4L；
C1, the hydrofluoric acid for adding 2L；
D1, the citric acid for adding 1kg；
E1, the potassium sulfide for adding 0.1kg；
F1, the op-10 for adding 1L；
G1, the hydrochlorate for adding 1L；
H1, the water for making total amount increase to 20L is eventually adding, stirred.
The working solution in Electroplate Factory A in actual use, with following remarkable result：
1. the use of the concentrated sulfuric acid is reduced, usage amount is original 5%；
2. cost for wastewater treatment is reduced, the use of piece alkali is reduced, institute's effluent directly reaches more than PH2.0, reach treatment waste water reaction standard, and adjusted without using alkali；
3. live pungent smell has been substantially improved；
4. generally having deep love for for operator is obtained；
5. it is low by 0.5% when average fraction defective is compared with using the concentrated sulfuric acid；
6. electroplating efficiency increased, and go out ray velocity soon, about 2 minutes.
The working solution in Electroplate Factory B in actual use, with following remarkable result：
Plating foaming phenomena is obviously improved, and blistering rate of the certain model before using the working solution is reduced within 5% up to 50% using the blistering rate after the working solution.
With above-mentioned according to desirable embodiment of the invention as enlightenment, by above-mentioned description, relevant staff can carry out various changes and amendments without departing from the scope of the technological thought of the present invention' completely.The technical scope of this invention is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
