Color-coated aluminum sheets are easily interfered by foreign objects and scratched during transportation, storage, construction and use. Therefore, in the face of this situation, two methods can be used to deal with them, so as to avoid the scratched parts from affecting the product The quality and use effect. At present, there are two methods for dealing with scratches on the surface: physical methods and chemical methods. Although these two methods are used to deal with scratches, their treatment effects are different. Let’s take a look at the specific differences.
1. The physical method is mechanical polishing, specifically sandblasting, wire drawing, etc. Generally, this method is used for deep scratches.
2. Chemical methods generally use chemical reagents for polishing. Simply put, chemical reagents are used to corrode the surface of the color-coated aluminum plate. The scratches have sharp edges and the corrosion speed is fast. Lighter scratches can be used after chemical polishing. Completely eliminated, the surface of the chemically polished material is bright and beautiful.
Usually the two methods are used together, and the surface of the color-coated aluminum plate can achieve a good decorative effect. If you just want the surface gloss to be consistent, you can also consider vibration polishing (there is a special vibration polishing machine), similar to a pot, put the abrasive in it, put the product in to vibrate, make the product and the abrasive rub, polish the surface, for irregularities The key is that the products are cheap, and they are usually processed outside.
Therefore, before dealing with the scratches on the surface of the color-coated aluminum sheet, you must choose a more appropriate treatment method according to the damage and demand of the sheet, so that the treatment effect can be better played, and it is really effective. A good treatment effect.
