Abstract
The invention discloses a metal annealing pickling-free electroplating method. The metal annealing pickling-free electroplating method is characterized by specifically comprising the following steps: a, cleaning the surface of a metal part to remove phosphorus shell and oil stains from the surface; b, annealing, heating to 850-950 DEG C by using a well type hydraulic cover vacuum resistance furnace, and naturally cooling to room temperature; c, washing with water, i.e., washing the dirt away from the surface of the metal part with tap water; d, electroplating, i.e., binding zinc particles to the surface of the metal part through current; e, packaging, i.e., packaging the electroplated metal part. The annealing is performed in the well type hydraulic cover vacuum resistance furnace, and the degree of vacuum is 10<-1>*133.3229d. Since the well type hydraulic cover vacuum resistance furnace is adopted during annealing, the annealed metal part has a bright surface and is provided with no oxide layer, so that electroplating can be performed after direct washing with water, the pickling process is omitted, and the purposes that the pickling is not used and the environment is not polluted are reached.
Description
Technical field
The present invention relates to a kind of electro-plating method, relate in particular to a kind of metal annealing without pickling electro-plating method.
Background technology
As everyone knows, a lot of metal partss, especially architectural hardware part all needs the laggard electroplating of annealing, to guarantee attractive in appearance and work-ing life.But, traditional electro-plating method be unable to do without this technological process of pickling, exist the major hidden danger of the discharging of waste liquid serious environment pollution after pickling, and in the process of pickling, produce a large amount of acid mists, obnoxious flavour has affected the healthy of people, does not meet national Sustainable development policy.
Summary of the invention
The object of the invention is to provides in order to overcome the deficiencies in the prior art-and kind can not pickling, metal annealing free from environmental pollution is without pickling electro-plating method.Its concrete grammar is:
A, metal parts removing surface, remove surperficial phosphorus shell, greasy dirt;
B, annealing, heat to 850-950 ℃ with well formula hydraulic cover vacuum resistance furnace, naturally cools to room temperature;
C, washing, rinse out metal parts surface foul with tap water;
D, plating, be attached to metal parts surface by electric current zinc particles;
E, packing, pack the metal parts after electroplating well.
Saidly in well formula hydraulic cover vacuum resistance furnace, anneal, its vacuum tightness is 10
-1* 133.3229d.
From technical scheme of the present invention, can find out, due to Bian well formula hydraulic cover vacuum resistance furnace when annealing, the metal parts surface-brightening after annealing, there is no zone of oxidation, just can directly wash laggard electroplating, remove this process of pickling, thoroughly solve the problem of acid mist and sewage discharge.And well formula hydraulic cover vacuum resistance furnace is the present inventor in the application of January in this year authorized patent, the test run(s) through nearly a year proves, metal parts surface-brightening after annealing, does not have zone of oxidation.Reached the present invention completely without pickling, goal of the invention free from environmental pollution.
Embodiment
Embodiment 1, and a kind of metal annealing is without pickling electro-plating method.Its concrete grammar is:
A, metal parts removing surface, remove surperficial phosphorus shell, greasy dirt;
B, annealing, heat to 850-950 ℃ with well formula hydraulic cover vacuum resistance furnace, naturally cools to room temperature;
C, washing, rinse out metal parts surface foul with tap water;
D, plating, be attached to metal parts surface by electric current zinc particles;
E, packing, pack the metal parts after electroplating well.
Saidly in well formula hydraulic cover vacuum resistance furnace, anneal, its vacuum tightness is 10
-1* 133.3229d.
