Abstract
Of the aluminum alloy activating solution, each liter contains zinc oxide 10-50 g, sodium hydroxide 100-300g, nickel sulfate 20-50 g, ferric trichloride 2-5 g and potassium-sodium tartrate 20-50 g. It is used int reating aluminium alloy before nickel plating at 30-50 deg.c for 20-200 sec. The treatment can lower the potential difference between the activated layer and the plated layer, raise the activity of the aluminum alloy surface, reduce the pollution to plating liquid, raise the binding force and protecting function of the plated layer, increase the service life of chemical nickel plating solution and reduce chemical nickel plating cost.
Description
Technical field
The present invention relates to the activated solution of the preceding aluminium alloy of chemical nickel plating.
Background technology
Processing before traditional aluminium alloy plating is to carry out double zincate process, because the potential difference between zinc and the nickel-phosphorus alloy coating is bigger, influences the bonding force and the protective of coating.
Summary of the invention
It is little to the purpose of this invention is to provide a kind of pollution, the activated solution that life cycle is long.
The technical scheme that realizes the object of the invention for the weight that each rises contained material in the activated solution is:
Zinc oxide 10-50g
Sodium hydroxide 100-300g
Single nickel salt 20-50g
Iron trichloride 2-5g
When Tartaric acid potassium sodium 20-50g used activated solution, temperature was controlled at 30-50 ℃, and soak time is 20-200s
The configuration of solution
The sodium hydroxide that scale is good dissolves with pure water earlier, then zinc oxide is added wherein, and the limit edged stirs; Dissolve iron trichloride, single nickel salt, Tartaric acid potassium sodium respectively with pure water again, iron trichloride, nickel sulfate solution are added respectively in the Tartaric acid potassium sodium solution; At last mixed Tartaric acid potassium sodium solution is added in sodium hydroxide and the zinc oxide mixing solutions, after careful the filtration, can use.
Adopt this solution that aluminium alloy is handled, reduced the potential difference of active layer and coating, improved the activity of aluminum alloy surface, and reduced pollution to plating bath, and improved the bonding force and the protective of coating, prolonged 0.5-1 cycle of chemical nickel-plating solution working life, in one liter of plating bath, cost-saved 4 yuan, 2 yuan of create beneficial results, 30,000 yuan of year create beneficial results (calculating) to consume 5000 liters of plating baths year.
