Color steel sheet
are very easy to be damaged by people and things during transportation, which affects the subsequent use. In order to deal with this situation, we can use two methods to solve the problem, so that the damaged place does not endanger the quality of the product and the subsequent use. use. At present, there are generally two ways to solve the scratches of color-coated rolls: physical methods and chemical methods. Both methods can be used to solve scratches, but the actual effects are different. Let us introduce them to you below.
1. The physical method is mechanical equipment grinding, metal wire drawing, etc. This method is generally used for deep wounds.
2. The organic chemical method generally uses chemicals to carry out grinding and polishing, and simply selects chemicals to etch a layer of the surface of the coated aluminum alloy plate. Due to the sharp edges and scratches, the convective heat transfer coefficient is fast, and the light can be completely removed after chemical polishing. The surface of the chemically polished raw material is bright and beautiful.
Generally, the two methods are applied together, and the color-coated aluminum alloy plate can achieve a very good decorative design effect. If you only expect the smoothness of the surface to be the same, you can also consider vibration grinding and polishing (with a professional vibration grinding and polishing machine), a similar pot, put wear-resistant materials in it, put the goods in it and vibrate, so that the goods and wear-resistant materials rub, The surface is polished and polished, and it works for irregular commodities. The key is that it is cheap and generally processed by external production.
