Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of copper bar sulfidation processing, in particular to a copper bar sulfidation production processing method. BACKGROUND

[0002] The copper bar is also called copper busbar or copper busbar, which is made of copper material, and the cross section is rectangular or chamfered (rounded) rectangular long conductor (now generally uses rounded copper bar to avoid producing sharp discharge), which plays a role in conveying current and connecting electrical equipment in the circuit, and the copper bar is widely used in electrical equipment, especially in complete power distribution device.

[0003] The copper bar sulfidation processing is a process of forming a sulfidation protective layer on the surface of the copper bar by chemical treatment, and the sulfidation layer (such as Cu2S and CuS) can effectively prevent the copper bar from oxidizing (such as blackening and copper green), especially in humid and sulfur-containing environment, and can enhance the corrosion resistance, and the sulfidation layer can reduce the contact resistance and reduce the electrochemical corrosion, which is suitable for electrical connection components such as busbar and switch contact, and can improve the electrical performance, and the hardness of the sulfidation film is higher than that of pure copper, which can improve the wear resistance and prolong the service life of the component. In the prior art, chemical sulfidation method, gas phase sulfidation method and electrochemical sulfidation method are usually used for sulfidation treatment of copper bar. When the chemical sulfidation method is used, the copper bar usually needs to be first pickled to remove the surface oxide and then immersed in a sulfidation solution (such as ammonium polysulfide and sodium sulfide solution). After reacting for several minutes to several hours at a certain temperature, a dense sulfidation layer is formed. Finally, the copper bar is cleaned and dried. The copper bar needs to go through the above-mentioned multiple processing steps. These processing procedures need different equipment and need to be transferred between multiple procedures, which causes the production process to be more complicated, affects the overall efficiency of the copper bar sulfidation treatment, and the overall structure is more complex, the cost of use is higher, and at the same time, the copper bar is easy to accumulate or the surface of the copper bar is partially shielded during the sulfidation treatment process, which affects the uniformity and comprehensiveness of the copper bar surface treatment and affects the sulfidation treatment effect of the copper bar.
