Abstract
The invention discloses an anti-corrosion treatment process for iron-based hardware. The iron-based hardware is put into an alkaline solution for soaking for 30 to 50 min so as to remove greasy dirt, and then the iron-based hardware is put into an acid solution for soaking for 20 to 30 min so as to remove surface oxides after cleaning with water; then iron-based hardware is put into a fine polishing machine, in which an abrasive is stored, for rolling and polishing, and the polishing time lasts for 8 to 12 min; cathode copper is taken as an anode, and the iron-based hardware is taken as a cathode and put into an electrolytic bath for electroplating, through the way, the anti-corrosion treatment process provided by the invention ensures that the iron-based hardware is excellent in corrosion resistant performance, copper plating on the surface of the hardware is uniform, and the product quality is improved greatly.
Description
Technical field
The present invention relates to a kind of complete processing, particularly a kind of anticorrosive treatment process of iron-based handware.
Background technology
Along with improving constantly of science and technology, hardware industry also constantly emerges, and present stage iron-based handware due to cheap, therefore use the most extensive, iron-based handware also has good use value simultaneously, then all there is more defect in iron-based handware in the process used, as: easily oxidized, be easily corroded, and for above-mentioned defect, all adopt copper-plated mode at present, but during copper facing in the prior art, its quality is all poor, density metal is not enough, increased number of stomata, and layers of copper is not firm, makes the second-rate of product.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of anticorrosive treatment process of iron-based handware, and iron-based handware can be made to have good Corrosion Protection, and even at handware copper coating, significantly improves the quality of product.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the anticorrosive treatment process providing a kind of iron-based handware, and concrete steps are as follows:
(1) removal of impurities: iron-based handware is put into basic solution and soaks 30-50min wipe oil, then by this iron-based handware through clear water rinse after put into acidic solution soak 20-30min remove oxide on surface;
(2) polishing: the iron-based handware after removal of impurities is put into the precision polisher depositing abrasive material and carries out tumbling, polishing time is 8-12min;
(3) electroplate: take electrolytic copper as anode, iron-based handware is negative electrode, puts into electrolyzer and electroplates.
In a preferred embodiment of the present invention, described basic solution by concentration to be the aqueous sodium hydroxide solution of 4-6% and concentration be 2-4% ammoniacal liquor in mass ratio routine 2:1 mix.
In a preferred embodiment of the present invention, described acidic solution by concentration to be the nitric acid of 13-15% and concentration be 10-14% phosphoric acid in mass ratio routine 1:1 mix.
In a preferred embodiment of the present invention, the particle diameter of described abrasive material is 1-2mm.
Beneficial effect of the present invention: the anticorrosive treatment process of iron-based handware of the present invention, can make iron-based handware have good Corrosion Protection, and even at iron-based handware copper coating, significantly improves the quality of product.
