What are the measures to control the surface quality of copper strip
What are the measures to control the surface quality of copper strips?
1. First, we must strengthen the control of the production process. Use a brush and clean water to clean up the impurities on the surface of the copper strip, and wrap it with liner paper before rolling to avoid scratches on the surface. In addition, we should adopt all-oil rolling methods, transform the degreasing equipment of rolling mills, slow down the rolling speed, and adopt all feasible methods to remove residual pollutants on the surface. At the same time, production management personnel must strengthen production management and strengthen monitoring.
2. Again, of course, it is necessary to strengthen the cleaning of the appearance and insist on a high degree of smoothness. During the rough rolling and annealing process, the surface of the copper strip will inevitably produce oxides, so the necessary cleaning methods such as pickling, degreasing, and passivation must be implemented well.
3. Secondly, it is necessary to strengthen the protection of the inert gas in the heat treatment process. Since the chemical properties of copper are very active, it can react quickly with the more active gaseous substances in the air during high-temperature heat treatment. Then it is necessary to protect the inert gas more effectively to prevent the copper strip from being oxidized. When necessary, an appropriate increase in inert gas is also one of the feasible methods.
4. Strengthen the control of the packaging of products. Special-shaped copper pipes must be dried after pickling. A humid environment will accelerate the corrosion of copper and affect the accuracy of the product. Therefore, in order to ensure the dryness of the product, it is necessary to take a double measure. While the product is as dry as possible, it is necessary to work hard on packaging. When packing, you can put moisture-proof paper in the packing box, and then wrap it with a plastic bag, which can effectively prevent the influence of external moisture during transportation.
