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 anode to form oxygen ions, which will oxidize the brightener, resulting in additional loss of the brightener. This requires frequent replacement of the electroplating solution and other preparations, which affects the quality of electroplating, increases the cost of electroplating, and affects the efficiency of electroplating

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as figure 1 As shown, it is the inductive nano-diaphragm realized by the present invention. As shown in the figure, the diaphragm includes a diaphragm main body 10 and conductive rods 20, 30, combined with figure 2 As shown, the diaphragm main body 10 includes a metal mesh 13, a nanometer mesh 12 and a protective mesh 11. The innermost part is a metal mesh 13, and the metal mesh 13 is placed close to the anode in the electroplating tank to form an induction cathode. The principle of repulsion prevents the negative ions of the gloss agent from passing through. The nano-mesh 12 is cove...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of electroplating, and in particular relates to an inductive nano-diaphragm used in an electroplating tank, which can effectively reduce the loss of brightener in the electroplating process. Background technique [0002] During the electroplating process, a brightener needs to be added to the electroplating solution. The brightener forms an almost complete adsorption monolayer on the surface of the plated part. Micropores that form and disappear continuously appear on the adsorption surface, and metal will form deposits in these micropores. Since the micropores are distributed randomly, the metal deposition is evenly distributed, resulting in a bright coating. At the same time, the geometric flattening effect can be used to continuously eliminate the existing small crystal faces to achieve the purpose of brightness. [0003] Theoretically speaking, the brightener is just an auxiliary reagent, which can be c...
