Description
Technical field
The present invention relates to electroplating technology field, particularly relate to a kind of Towel hanging rack with surface composite plating.
Background technology
Along with constantly riseing of nickel price, under the prerequisite ensureing coating function, the thickness reducing electroless nickel layer can directly reduce Electroplating Production cost, reduces discharge of wastewater, reaches the object of energy-saving and emission-reduction.
In the development of modern electroplating technology, composite plating is most active part, studies successfully from the thirties in 20th century, and since going into operation the sixties, development is very rapid, and Application Areas constantly expands.Simultaneously in decorative plating, people are in order to obtain high anti-corrosion coating, multi-layer plating has been invented by Atotech company of the U.S., from two nickel until three layers of nickel, four layers of nickel of today, to improve the Corrosion Protection of decorative coating, in order to improve its anti-corrosion function further, composite plating being used as nickel envelope, namely forming micropore chromium with very thin composite deposite and improving its barrier propterty.The principle of the anti-rust structure of nano compound electroplating is: non-conductive micropartical is electroplated, and will produce countless pores when then carrying out chromium plating in the above.On this plated film, corrosion current can be spread out by unlimited, thus makes the speed of corrosion more steadily slow.
It is reported, in October calendar year 2001, by the nano-plating slurry of Aboluo Electromechanical Tech. Development Co., Chongqing's independent development and the process system of nano-plating, not only can save material, reduce costs, and its key is to give coating the beyond thought premium properties such as wear-resisting, the nano-plating slurry of the said firm is α-A1
2o
3the system of composition.But there is the shortcomings such as stress is large in this coating.
At present these composite deposites exist that stress is large, coating is thick and the shortcoming such as solidity to corrosion is poor, up to now, also do not see that coating is very thin and corrosion resistance excellent is integrated complex function coating appears on the market, also have no relevant patent and research paper report.
Towel hanging rack is often in moist environment, therefore has etch-proof requirement, and these products also have ornamental demand attractive in appearance simultaneously.Therefore a kind of good corrosion resistance is needed badly, and the composite deposite of appearance looks elegant.
Summary of the invention
The object of the invention is to propose a kind of Towel hanging rack with surface composite plating, this composite deposite has good corrosion resisting property, and appearance looks elegant.
For reaching this object, the present invention by the following technical solutions:
A kind of Towel hanging rack with surface composite plating, this Towel hanging rack material is soft steel, described composite deposite comprises and the electrodeposited chromium layers outside the electroless nickel layer of substrate contact and electroless nickel layer, the thickness of described electroless nickel layer is about 2-3 μm, and the thickness of electrodeposited chromium layers is about 8-10 μm, and wherein the plating solution of electroless nickel layer consists of: single nickel salt is 200-210g/L, nickelous chloride is 65-75g/L, boric acid is 50-54g/L, ferric sulfate 10-20g/L, polyvinylpyrrolidone 0.1-0.2mol/L; Wherein the plating solution of electrodeposited chromium layers consists of: chromium sulphate 0.30-0.40mol/L, sodium sulfate 0.9-1.1mol/L, boric acid 0.3-0.5mol/L, magnesium sulfate 0.2-0.4mol/L, sodium lauryl sulphate 0.0001-0.004mol/L, formic acid 0.2-0.4mol/L, brightening agent MP-33320-30ml/L, brightening agent MP-36610-14ml/L.
Electro-nickel process parameter is: pH is 3.5-4.5, and current density is 10-12A/dm
2, temperature is 40-44 DEG C, and the time is 13-17min.
Electrodeposited chromium processing parameter is: pH is 3-4, temperature, 45-55 DEG C, current density 12-14A/dm
2, the time of plating is 40-60min.
The proportioning that present invention focuses on nickel salt and molysite in bath composition in plating nickel dam, particularly nickel dam is selected, and makes in scope that in plating solution, the ratio of the two limits in said components, could obtain excellent in effect.For coordinating this nickel layer, the bath composition of chromium coating be also optimized and adjusted, making to be suitable in electroplating process, forming good metallurgical binding with above-mentioned nickel layer.Meanwhile, for the adjustment of two kinds of solution compositions, have selected applicable electroplating technical conditions.Composite by science, on the basis of theoretical and great many of experiments, the creationary above-mentioned parameter scope determining nickel layer bath composition, chromium coating bath composition, nickel layer electroplating technology, chromium coating electroplating technology four variablees, reach coordination technique effect, make the perfect excellence of coating performance prepared.
Compared with prior art, the present invention has following beneficial effect:
1., by increasing nickel layer, making coating and basal body binding force excellence, use more than 8 years non-scales can be continued in bathroom environment, do not peel off.
2. and chromium coating excellent anti-corrosion performance, the non-variable color of more than salt-fog test 200h.
3. and appearance looks elegant is beautiful.Can be matched in excellence or beauty Stainless Steel Products completely, but the cost comparing Stainless Steel Products can reduce by more than 40%.Except Towel hanging rack, be also suitable for the products such as the hook of bath articles.
