Abstract

The invention relates to a method of adjusting the copper ion concentration in copper pyrophosphate electroplating solution. According to the device, an adjusting tank is disposed in an electroplating tank, and an inert anode plate is used as an anode in an electroplating tank body. According to the method, the copper ion concentration can be adjusted, thus improving the quality of coppered steel wires, reducing the production cost and controlling heavy-metal pollution.

Description

Cupric pyrophosphate electroplate liquid copper ion concentration setting device
Technical field
The present invention relates to a kind of device of regulating concentration of heavy metal ion, thereby especially in the cupric pyrophosphate electroplating solution, by regulating copper ion concentration, reach the device that improves the Coppered Steel Wire quality, reduces production costs, controls heavy metal contamination.
Background technology
At present, thus in known adjusting cupric pyrophosphate electroplating solution, the ordinary method of concentration of heavy metal ion is that the discharge electroplate liquid reduces concentration of heavy metal ion in electroplate liquid.The cupric pyrophosphate electro-coppering be using metal plated steel wire or by the plating matrix as negative electrode, copper as anode pad steel wire or by the plating matrix below, steel wire or by the plating matrix in electroplate liquid, move, by electrochemical reaction by copper be plating to steel wire or by the plating matrix on.In electroplating process, because the increase of current efficiency along with current density reduces, current efficiency is lower than 100%, and the speed that anode copper dissolves is far longer than the negative electrode steel wire or is plated matrix by copper-plated amount, Cu in solution 2+Content is relatively more and more higher, too high Cu 2+Content can cause steel wire or quilt plating matrix coating is coarse, crystal grain is excessive, thereby affect quality product.General treatment process is the discharge electroplate liquid, then reduces Cu in electroplate liquid 2+Concentration, this method, to environment, increases production cost.
Summary of the invention
In order to solve Cu in the cupric pyrophosphate electroplating solution 2+The problem of excessive concentration, the invention provides a kind of setting device of concentration of heavy metal ion, and this device can consume Cu unnecessary in electroplating solution 2+, keep Cu in electroplating solution 2+Stablizing of concentration, thus the good quality of Coppered Steel Wire guaranteed, avoid the discharge of heavy metal in electroplate liquid to cause the pollution to environment.
The technical solution adopted for the present invention to solve the technical problems is: regulating tank is set in plating tank, regulates in cell body and use the inert anode plate as anode.During plating, steel wire or quilt plating matrix continue deposition Cu as negative electrode 2+, the inert anode plate is dissolved copper not, and a brine electrolysis becomes O 2And H 2.
The electric current of regulating tank is according to electroplate liquid Cu 2+Concentration is regulated.Work as Cu 2+During excessive concentration, increase electric current in regulating tank and slow down shot copper ion dissolution rate, Cu 2+Concentration decreases.Otherwise, work as Cu 2+When concentration is on the low side, reduces electric current in regulating tank and promote shot copper ion dissolution rate, Cu in solution 2+After concentration is effectively controlled, just do not affect by plating matrix coating quality, simultaneously without passing through the discharge electroplate liquid to reduce Cu yet 2+Content.In addition, because the regulating tank brine electrolysis produces H +, can reduce the pH value of electroplate liquid, avoid the higher enhancing solution acidic of pH value and then affect the Coppered Steel Wire quality.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is copper facing schematic diagram of the present invention.
Fig. 2 is the longitudinal section structural map of an embodiment of regulating tank.
1. cathode rollers in figure, 2. steel wire, 3. inert anode plate, 4. shot copper, 5. electroplate liquid, 6. power supply barretter, 7. stainless steel anode plate.
Embodiment
In Fig. 1, the inert anode plate 3 that replaces copper anode is padded on below steel wire 2, and steel wire 2 is moved by right side in electroplate liquid 5 to the left as negative electrode, and the shot copper 4 that electrochemical reaction will be placed in stainless steel anode plate 7 and be immersed in electroplate liquid 5 is decomposed into Cu 2+Be plating to the top layer of steel wire 2.
In embodiment illustrated in fig. 2, Cu in electroplating solution 5 2+Because dissolution rate higher than steel wire 2 by plating speed, Cu in electroplate liquid 5 2+When content is progressively too high, controls power supply barretter 6 and increase electric currents, Cu 2+Content correspondingly reduces.Otherwise, Cu in electroplate liquid 5 2+When content is on the low side, controls power supply barretter 6 and reduce electric current with active balance Cu 2+Content.Cu 2+Content is effectively controlled, and steel wire 2 copper plate quality just can be guaranteed, and simultaneously, has also avoided the discharge of heavy metal in the electroplate liquid to cause the pollution to environment.
