Problems solved by technology

[0003] Theoretically speaking, the brightener is just an auxiliary reagent, which can be consumed synchronously according to the designed ratio in actual production
However, in the actual electroplating process, especially when an insoluble anode is used for electroplating, water molecules will be electrolyzed near the anod...

The invention discloses an induction type nanometer diaphragm. The induction type nanometer diaphragm at least comprises a metal net, a nanometer net and a conducting rod, one end of the conducting rod is connected with the metal net, the other end of the conducting rod is close to an electroplating cathode, the metal net is arranged close to the anode to form an induction cathode, and negative ions of a gloss agent are prevented from passing through the principle that like poles repel each other. The conducting rod extends out of the metal net to be close to the electroplating cathode so as to form an induction anode, meanwhile, the nanometer net at least covers the metal net from one side face, and the nanometer net has the effect of isolating gas, especially decomposed oxygen ions, so that it is difficult for the oxygen ions to penetrate through, the physical isolation effect is achieved, and the loss of brighteners is reduced.

Example Embodiment

[0018] In order to make the objectives, technical solutions and advantages of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely intended to illustrate the invention and are not intended to limit the invention.
[0019] like figure 1 As shown, the inductive nano-diaphragm according to the present invention, as shown in the figure, the diaphragm contains the separator body 10 and the conductive rods 20, 30, combined figure 2 As shown, there is a diaphragm body 10 further comprising a metal mesh 13, a nanomes 12, and a protective network 11, an innermost surface is a metal mesh 13, and the metal mesh 13 is adjacent to the anode in the plating tank to form a sensor cathode, through the same property phase Principle, the negative ion of the blocking glossy agent passes. The nanowed 12 is covered in the metal mesh 13, and the nanowire 13 has the effect of the isolation gas, particularly decomposed oxygen ions, so that the oxygen ion is difficult to pass, thereby generating the effect of physically isolating oxygen ions and the brightener, thereby reducing the brightener Loss.
[0020] One end of the conductive rod (20, 30) is connected to the electroplated cathode; the conductive rod extends from the metal mesh 13 to form an induced male stage, and the nanowne 12 is covered from one side cover from one side 13 superior.
[0021] Typically, there is a mesh hole on the metal mesh 13, usually, 10 dedicated copper nets to have a better isolation effect.
[0022] The nanownamen 12 is nano-stage, a nanometer or micron aperture, a film or cloth, preferably a web, a film or cloth having a nano aperture, such as a nanopsis, a dialysis film, or the like.
[0023] A protective network 11 is also covered with the outside of the nanowed 12, which protects the nanofire 12 and the metal mesh 13.
[0024] The protective network 11 is usually made of a film or cloth, or other material can be used as long as it can be permeable.
[0025] If the strength is harder, the metal mesh itself has a steel formation support, the nanofilm and protective networks can be stably fixed on the metal net. However, when the metal mesh is relatively thin, the rigid support structure cannot be formed, and it is a metal soft network, and there is a frame support for metal soft network and nanofilm and protective network. At this time, the protection network 11 can also be designed to a rigid structure. If the metal network is relatively thick, itself has certain strength and hardness, and the metal network does not need to protect the network, and the protection network 11 only needs to provide a protective action.
[0026] The two conductive rods 20 and 30 may be consistent, or may be inconsistent; when inconsistent, the corresponding electroplating progress can be calculated by loss of its length.
[0027] The nanowed 12 can be covered from the two sides of the metal mesh 13 on the metal net 13, image 3 As shown, in the form of another diaphragm body 10 of the present invention, in this form, the nanofire 12 can be covered from one side of the metal mesh 13 on the metal net 13, that is, the metal network 13 faces the anode. Expose it.
[0028] In summary, the diaphragm provided by the present invention, physically separated from the oxygen ions produced from the insoluble anode from the brightness by the metal mesh and the nanowin, and the brightulife is no longer affected by oxygenation, thereby affecting its effect. Reduce the losses of the brightener.
[0029] Thus, the present invention ensures the life of the electroplating fluid, reducing the plating cost, avoiding frequent replacement of plating solution, and improving electroplating efficiency. After testing, in the copper-plated process, it is possible to extend the life of the electroplating fluid, which effectively improve the life of the electroplating fluid, greatly reduces the waste of the material, and can reduce the environmental pollution, low carbon environmental protection.
