Description
Technical field
The invention belongs to handware processing technique fields, and in particular to a kind for the treatment of process of the iron-based handware of anticorrosion.
Background technique
With the continuous improvement of science and technology, hardware industry also constantly emerges, and iron-based handware is due to price at this stage
It is cheap therefore most widely used, while iron-based handware also has preferable use value, then iron-based handware makes
There are more defects during, such as: it is easily oxidized, is easily corroded, and in view of the foregoing drawbacks, it is all made of at present copper-plated
Mode, but when copper facing in the prior art, quality is poor, density metal is insufficient, increased number of stomata, and layers of copper is loosely
It leans on, so that product is second-rate.
Summary of the invention
The present invention is directed to the situation of the prior art, provides a kind for the treatment of process of iron-based handware of anticorrosion.
The present invention uses following technical scheme, and a kind for the treatment of process of the iron-based handware of anticorrosion, specific steps are such as
Under:
(1) it cleans: iron-based handware being put into alkaline solution and impregnates 30-50min and degreases, then by the iron-based hardware
Part, which is put into acid solution after clear water rinses, impregnates 20-30min removal oxide on surface；
(2) it polishes: the iron-based handware after removal of impurities being put into storage has in the precision polisher of abrasive material and carry out tumbling, polish
Time is 8-12min；
(3) be electroplated: using cathode copper as anode, iron-based handware is cathode, is put into electrolytic cell and is electroplated.
(4) it is passivated: the handware of drying being placed in the passivating solution of room temperature and is impregnated 3~5 minutes, carry out coating surface passivation
Processing；
(5) cleaning, drying: the handware after passivation is rinsed to surface using circulating water without passivating solution, is then dried again
It does to dry tack free.
As a further improvement of the above technical scheme, the alkaline solution is water-soluble by the sodium hydroxide that concentration is 4-6%
Liquid is mixed with the ammonium hydroxide example 2:1 in mass ratio that concentration is 2-4%.
As a further improvement of the above technical scheme, nitric acid and concentration that the acid solution is 13-15% by concentration
It is mixed for the phosphoric acid example 1:1 in mass ratio of 10-14%.
As a further improvement of the above technical scheme, the partial size of the abrasive material is 1-2mm.
As a further improvement of the above technical scheme, the passivating solution is that CrO3, NaCl and H2SO4 are dissolved in distillation
In water, content is respectively as follows: 80~90g/L of CrO3；1~2g/L of NaCl；25~30ml/L of H2SO4.
A kind for the treatment of process of the iron-based handware of anticorrosion disclosed by the invention, the beneficial effect is that, anti-corrosion of the present invention
The treatment process for losing iron-based handware enables to iron-based handware to have good Corrosion Protection, and iron-based five
Golden part copper coating is uniform, and the quality of product greatly improved.
Specific embodiment
