Abstract
This invention relates to a electroplating technology which replace cauterize by three initiatives alloy. The technology compounding includes: stannous chloride, cobalt chloride, butter of zinc, potassium pyrophosphate, zinc-plating additive, zinc-plating stabilizer. The PH is:8.5-9.5, temperature: 20DEG C-45DEG C, current density: 0.1-2A/dm2,the anode is pure tin plate. The specific operation is applying this technology on the original copy which has plated nickel.
Description
Affiliated technical field
The invention belongs to a kind of nothing and iron electroplating technology, especially a kind of electroplating technology that irons with the ternary alloy replacement.
Background technology
At present, electroplating industry is serious pollution industry always, especially carries out the plating that metal irons, and its pollution level is even more serious, this be because the residue that irons to the harm of environment even more serious due to, to this, also do not have good terms of settlement at present.
Summary of the invention
In order to overcome the pollution problem that residue is ironed in the electroplating industry plating, the invention provides a kind of electroplating technology that irons with the ternary alloy replacement, this technology is to electroplate under the condition that does not iron fully, this has just fundamentally got rid of the pollution problem of ironing, this technology is of value to environmental protection, be beneficial to man, have high application value.
The present invention solves the technical recipe that its technical problem adopts:
Tin protochloride: 20-30 grams per liter
Cobalt chloride: 8-12 grams per liter
Zinc chloride: 5-10 grams per liter
Potassium pyrophosphate: 220-280 grams per liter
In generation, ironed zinc-plating additive: the 20-30 milliliter/liter
In generation, ironed zinc-plated stablizer: the 1-2 grams per liter
PH value: 8.5-9.5
Humidity: 20 ℃-45 ℃
Current density: 0.1-2A/dm
2
Anode: pure tin plate.
Its concrete operations are: on the basis of original paper Ni plated, under the processing condition of prescription of the present invention and former nickel plating, can finish the plating that this nothing irons again.
Its beneficial effect is: this technology is to electroplate under the condition that does not iron fully, and this has just fundamentally got rid of the pollution problem of ironing, and this technology is of value to environmental protection, is beneficial to man, and has high application value.
Embodiment
In 10 liters of electroplate liquids, put into tin protochloride 250 grams, cobalt chloride 90 grams, zinc chloride 80 grams, potassium pyrophosphate 2500 grams, each 250 milliliters of zinc-plated interpolation Ji and zinc-plated stablizers, pH value transfers to 9.0,30 ℃ of temperature modulation, the anode pure tin plate can not have the plating of ironing.
Claims (2)
1. one kind replaces the electroplating technology iron with ternary alloy, it is characterized in that: the present invention solves the technical recipe that its technical problem adopts and is:
Tin protochloride: 20-30 grams per liter
Cobalt chloride: 8-12 grams per liter
Zinc chloride: 5-10 grams per liter
Potassium pyrophosphate: 220-280 grams per liter
In generation, ironed zinc-plating additive: the 20-30 milliliter/liter
In generation, ironed zinc-plated stablizer: the 1-2 grams per liter
PH value: 8.5-9.5
Humidity: 20 ℃-45 ℃
Current density: 0.1-2A/dm
2
Anode: pure tin plate.
2. an electroplating technology that irons with the ternary alloy replacement is characterized in that: on the basis of original paper Ni plated, under the processing condition of prescription of the present invention and former nickel plating, can finish the plating that this nothing irons again.
