Abstract
The invention discloses an insoluble anode and making technique of steel core barrel plating nickel, which comprises the following steps: adopting metal titanium as base of anode; coating ruthenirialloy on the surface; removing oil for base; cleaning.
Description
Technical field
The present invention relates to electroplating technology, specifically a kind of insoluble anode preparation technology who is used for steel core barrel-plating nickel.
Background technology
At present, in steel core barrel-plating nickel coin blank cake plating production process, the anode that adopts all prepares with the nickel material, (general anode efficiency is 100% to anodic efficient greater than cathode efficiency in plating production process, anode efficiency is 85%～92%), make that the nickel ion concentration in the electroplate liquid is constantly soaring along with the increase of time, the requirement that has exceeded electroplating technology, therefore in continuous production, to constantly discharge a part of electroplate liquid, and with deionized water dilution, additive is adjusted to required electroplate liquid concentration again after, can continue to produce, so not only pollute environment, also wasted metallic nickel and additive in a large number.And with the nickel anode in the graphite anode instead of part steel core barrel-plating nickel, can not satisfy the needs of Electroplating Production because the current potential of its graphite is high, with the nickel anode in the titanium corrugated panel anode instead of part steel core barrel-plating nickel, also because the titanium surface forms oxide film and passivation easily, make the current density in the plating tank reduce, nickel deposition speed can't normally produce slowly.
Summary of the invention
A kind of insoluble anode for use in steel core barrel-plating nickel preparation technology of providing at the deficiencies in the prior art is provided, nickel anode during its instead of part steel core barrel-plating nickel is produced, significantly reduce the quantity discharged of electroplate liquid, reduce the consumption of metallic nickel and additive, reduced the plating liquid discharge pollution on the environment simultaneously.
The concrete technical scheme that realizes the object of the invention is: a kind of insoluble anode for use in steel core barrel-plating nickel preparation technology, it is to be base material with the metal titanium, at its surface-coated iridium ruthenium alloy, be used for the segment anode of steel core barrel-plating nickel production process, its preparation technology comprises following operation:
(1), oil removing:, remove oil stain with 70～80% acetone solns dipping again with stain remover clean metal titanium substrate surface greasy dirt and foul.
(2), clean: the metal titanium base material after the above-mentioned oil removing was boiled 2～3 hours with 50% leather acid solution, clean successively with tap water, pure water, ethanol again.
(3), the coating of iridium ruthenium alloy: the metal titanium substrate surface after above-mentioned oil removing, the cleaning is applied the iridium ruthenium alloy by following step:
1., the metal titanium substrate surface applies the mixed solution of being made up of chloro-iridic acid, ruthenium trichloride and tetrabutyl titanate, its proportioning is 1: 2: 5.
2., far-infrared baking 1～1.5 hour, temperature is at 400～450 ℃.
3., repeat above-mentioned 1., 2. step 25～30 time, make it form eutectic.
The present invention is in the production process of steel core barrel-plating nickel, can active balance nickel ion concentration in the steel core barrel-plating nickel solution, the stable electrical plating liquor significantly reduces the quantity discharged of electroplate liquid, reduce the consumption of metallic nickel and additive, reduced the plating liquid discharge pollution on the environment simultaneously.
Embodiment
The present invention is base material with the metal titanium, is used as insoluble anode in the steel core barrel-plating nickel production process at its surface-coated iridium ruthenium alloy, the nickel anode in the instead of part steel core barrel-plating nickel production process, and its preparation is undertaken by following operation:
(1), oil removing:, remove oil stain with 70～80% acetone solns dipping then with the greasy dirt and the foul of stain remover cleaning titanium-based surface.
(2), clean: the titanium base after the above-mentioned oil removing was boiled 2～3 hours with 50% oxalic acid solution, clean successively with tap water, pure water, ethanol then.
(3), covering of iridium ruthenium alloy is coated with: the titanium-based surface after above-mentioned oil removing, the cleaning is applied the iridium ruthenium alloy by following step.
1., to apply by concentration be the mixed solution that the tetrabutyl titanate of 40% chloro-iridic acid, 38% ruthenium trichloride and 37% is formed to the metal titanium substrate surface, its proportioning is 1: 2: 5.
2., far-infrared baking 1～1.5 hour, temperature is 450 ℃.
3., repeat above-mentioned 1., 2. step 25～30 time, make it form eutectic.
Embodiment
According to the electroplating technology of steel core barrel-plating nickel and the equilibrium relationship of cathode and anode efficient, during ordinary production, every production line has 57 groups of electrodes approximately in work, electroplate a drum with every group and calculate, set(ting)value is the 9000Ah/ erect-position, cathode efficiency 90%, adopt 3～5 groups of anode replacement nickel anodes of the present invention, the reaction of cathode and anode tends to balance like this, and the nickel ion concentration in the electroplate liquid, pH value, quality product are all highly stable, and the consumption of metallic nickel and acid also reduces simultaneously.
