A kind of electroplating post-treatment process of silver-plated copper wire

Abstract

The invention discloses an electroplating post-treatment process for silver-coated copper wires, which relates to the field of silver-coated copper wires. To produce silver-plated copper wire products of different diameters, a passivation mechanism is used to passivate the silver-plated copper wire during the drawing process of the drawing wheel, and a protective film is formed on its surface, and then the washing mechanism removes the residual silver-plated copper wire. The wire passivation solution is removed, and then dried to make a silver-plated copper wire product. The silver-plated copper wire product is formed by one-time stretching, which avoids the stretching instability caused by multiple stretching, which in turn leads to silver-plated copper wire products. The copper wire products have the defects of uneven thickness and unstable quality, and a protective film is continuously formed on the surface of the silver-plated copper wire product, which ensures that a dense protective film is formed everywhere on the silver-plated copper wire product, which protects the silver-plated copper wire product. Wire products will not have the problem of discoloration and deterioration for a long time.

Description

technical field [0001] The invention relates to the field of silver-plated copper wires, in particular to an electroplating post-treatment process of the silver-plated copper wires. Background technique [0002] Silver-plated copper wire is a thin wire drawn by wire drawing machine after silver plating on high-quality oxygen-free copper wire or low-oxygen copper wire. It has excellent electrical conductivity, thermal conductivity, corrosion resistance and high temperature oxidation resistance. , Silver-plated copper wire is widely used in electronics, communications, aerospace, military and other fields to reduce the contact resistance of metal surfaces and improve welding performance; [0003] Silver is a white bright, malleable, malleable and reflective metal with good electrical conductivity and solderability. Silver has high chemical stability and is resistant to corrosion by alkali and some organic acids. It interacts with oxygen, and silver is easy to polish and has a...

Problems solved by technology

[0005] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a post-plating treatment process for silver-plated copper wires: the silver-plated copper wires are stretched by using several pulleys in the post-plating treatment equipment to make it produce different The diameter of the silver-plated copper wire product, the passivation mechanism is used to passivate the silver-plated copper wire during the stretching process of the pulley, forming a protective film on its surface, and then the washing mechanism passivates the remaining silver-plated copper wire The solution is removed, and then dried to make a silver-plated copper wire product, which solves the problem of uneven stretching of the existing silver-plated copper wire, resulting in uneven thickness of the copper wire. The problem of effective protection of copper wire
