Method for improving copper bar surface treatment effect

Abstract

The invention relates to the technical field of copper bar surface treatment, and provides a method for improving a copper bar surface treatment effect. The method comprises the following steps of polishing, pickling passivation, primary drying, screening, protective agent coating, standing, cleaning, secondary drying and packaging. The method overcomes the defects in the prior art, is reasonable in design, and is good in copper bar surface cleaning effect by separately treating burrs, oxide skin, grease and craters. Copper bars are screened after the surfaces of the copper bars are cleaned, the copper bars with large craters are repeatedly cleaned, and the cleaning percent of pass is increased. After the surface treatment of the copper bars is completed, the surfaces of the copper bars are uniformly contacted with an oxidation protective agent JLR-510 in a soaking manner, so that the surfaces of the copper bars are prevented from contacting air to oxidize and discolor. After the copper bars are processed, the primary color of the copper bars is maintained, the surfaces of the copper bars are free of impurities, overall attractiveness is achieved, and using and selling are facilitated.

Description

technical field [0001] The invention relates to the technical field of surface treatment of copper bars, in particular to a method for improving the surface treatment effect of copper bars. Background technique [0002] Copper bars, also known as copper busbars, copper busbars or copper busbars, and grounding copper bars, are made of copper and have a rectangular or chamfered (rounded) rectangular cross-section. effect of the device. [0003] When the copper bar is processed and formed, there will be burrs, scale, grease and other impurities on its surface. The burrs are easy to hurt people, and other impurities affect its working effect and aesthetics. Therefore, surface treatment is required before packaging. The surface treatment method of the bar is mainly to polish the surface. This method is not effective in treating the welding scars and grease on the surface of the copper bar, and it is easy to polish excessively or not completely; and the surface of the copper bar ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a method for improving the surface treatment effect of copper bars, which overcomes the deficiencies of the prior art, and has a reasonable design, which solves the problem that the current method of surface treatment of copper bars is mainly to polish the surface. , this method is not effective in treating the scars and grease on the surface of the copper bar, and it is easy to polish excessively or not completely and the surface of the copper bar is easily oxidized after packaging, which affects sales and use; It is treated separately from grease and welding scars, and the surface cleaning effect of copper bars is good; after the surface cleaning of copper bars is completed, it is screened, mainly for repeated cleaning of copper bars with large welding scars, and the cleaning pass rate is improved; After the surface treatment is completed, the surface of the copper bar is evenly exposed to the oxidation protection agent JLR-510 by soaking to avoid the surface of the copper bar from being oxidized and discolored by air; after the copper bar is treated, while maintaining the original color of the copper bar, the surface of the copper bar is free of impurities and the overall appearance is beautiful , conducive to use and sales
