Abstract
The new type electroplating equipment has an electroplating tank for holding electroplating solution, material to be plated as cathode, metal which is not dissolved in electroplating solution as anode and electric current device for applying current into electroplating solution. The electroplating equipment of the described anode is equipped with the film for preventing the O2 produced from anode in the course of electroplating from contacting with organic additives of brightening agent, etc., mixed in the electroplating solution.
Description
Technical field
The present invention relates to a kind of electroplanting device that has novel texture cheaply that has not only improved electroplating quality and reduced the pharmaceutical chemicals expense.
Background technology
In general, when electric plating, in electroplate liquid, mix organic additive such as gloss-imparting agent in order to improve electroplating quality.Then, passing to galvanic current between by the negative electrode of electronplate and anodic two electrodes, the metallic cation in the electroplate liquid moves, separating out plating on by the cathode surface of electronplate to negative electrode, and the negatively charged ion OH in the electroplate liquid
-And SO
4 2-Generate O in anodic oxidation
2
But, because such O that generates
2Oxidizing power make that the organic additive of blended gloss-imparting agent and so on is oxidized in the electroplate liquid, organic additive rotten, becoming does not have the function of self.Therefore, electroplating quality reduces, in order to improve electroplating quality, consider that the rotten amount of organic additive then must mix a large amount of organic additives, so the expense of pharmaceutical chemicals rises, the cost of goods rises.
Summary of the invention
The present invention is exactly in order to solve the above problems, and the purpose of this invention is to provide a kind of O that produces from anode when electroplating
2Hardly be blended in electroplate liquid in organic additive contact, thereby galvanized quality improves, the pharmaceutical chemicals expense reduces makes goods have the electroplanting device of novel texture cheaply.
According to the present invention, provide a kind of plating tank that comprises the electroplate liquid that is used for packing into, with by electronplate as negative electrode, with the metal that is insoluble to electroplate liquid as anode, to the electroplanting device of the alive current device of electroplate liquid, this electroplanting device is characterised in that, is equipped with the O that produces from anode when preventing to electroplate around described anodic
2The film that contacts with organic additives such as gloss-imparting agent in being blended in electroplate liquid.
Brief description of drawings
Fig. 1 is the sketch chart of expression one embodiment of the present of invention.
The description of embodiment
According to appended accompanying drawing the preferred embodiments of the present invention are described below.Fig. 1 is the sketch chart of expression one embodiment of the present of invention.
The present invention relates to a kind of plating tank 10 that comprises the electroplate liquid that is used for packing into, with by electronplate as negative electrode 30, with the metal that is insoluble to electroplate liquid as anode 20, to the electroplanting device of the alive current device 50 of electroplate liquid.In described electroplate liquid, mix organic additives such as gloss-imparting agent in order to improve electroplating quality.Described then negative electrode 30 becomes the transfer roller form, and its formation makes and transmitted by this transfer roller by electronplate electronegatively, applies galvanic current by the current device 50 that is connected on the power supply on described anode 20 and negative electrode 30.
Then, around described anode 20, be equipped with only selection and see through H
+Film 40.This film 40 portion within it has the passage that diameter is about 4-5 nanometer, H
+Be moved in the mode of passing through from this passage.This kind film is to utilize to have (CF
2-SO
3H) polytetrafluoroethylene (PTFE) of side chain is made with the thickness with about 50-250 nanometer, but preferred commodity in use name Nafion (DUPONT company of manufacturers).At this moment, supply with the supply-pipe 62 of groove 60 and be connected with being connected to another sulphuric acid soln that the storage sulphuric acid soln uses by described film 40 isolated spaces, by the sulfuric acid concentration that keeps constant level in film 40 space at interval.This kind film 40 is according to being fixedly installed by the other holding components 49 of configuration in the described anode 20 residing positions of inside, but holding components 49 is the simplified shapes that become a side opening, fixedly installs film 40 at the peristome of this holding components 49.
So the present invention who constitutes, when plating is carried out, the negatively charged ion OH in the plating
-And SO
4 2-On anode 20, produce O
2Described film 40 is because only select to see through H
+So, at the O of anode 20 generations
2Be not by film 40, but be discharged to the outside by the supply-pipe 62 that is connected with sulphuric acid soln supply groove 60.Prevented O thus
2With the organic additive reaction of adding in the electroplate liquid.
As mentioned above, according to the invention provides a kind of O that produces at anode can prevent to electroplate the time
2With the organic additive reaction of adding in the electroplate liquid, thereby can access high-quality galvanized electroplanting device with new texture.And in the occasion of using this electroplanting device, can reduce the usage quantity of the additive of gloss-imparting agent and so on, thereby the pharmaceutical chemicals expense reduces the cost reduction.
