Surface scratch treatment method of aluminum sheet

Last Updated: 2021-05-20

Scratches on the surface of aluminum sheets are more likely to occur in the process of aluminum sheet processing. It is often caused by improper processing and treatment, which causes the surface to be damaged, which seriously affects the aesthetics of the aluminum sheet. However, the scratches have already appeared. The following describes the surface scratch treatment of the aluminum sheet. method.

The surface scratches of aluminum sheets can be treated. In short, there are two methods: physical and chemical: the physical method is mechanical polishing, and the details include sandblasting and wires drawing. This method is generally used for deeper scratches. Chemical methods generally use chemical reagents for polishing. In short, chemical reagents are used to corrodse the surface of aluminum. The scratches have sharp edges and the corrosion speed is fast. Lighter scratches can be completely eliminated after chemical polishing. , The chemically polished material has a bright and beautiful appearance. Generally, the two methods are used together, and the appearance of the aluminum material can achieve a good decorative effect.

The solution to the scratch on the surface of the aluminum sheet:

  • The working belt on the alloy aluminum sheet mold needs to be polished and smooth, whether the empty knife of the extrusion mold is enough, and the surface is smooth.
  • In the process of prodsucing alloy aluminum sheets, pay attention to the prodsuction of mold lines. Once the lines are generated, the mold needs to be loaded in time to stop prodsuction.
  • In the process of aluminum sheet sawing: each sawing needs to clean the cutting sawdust in time. Prevent secondary scratches.
  • Similarly, in the process of CNC machining aluminum sheets, it is also necessary to prevent the aluminum slag remaining on the fixture from being scratched.
  • There are exposed industrial aluminum profiles or graphite strips on the discharge track or swing bed with hard inclusions. Avoid scratches on the surface of the aluminum sheet when hard debris comes in contact with the aluminum sheet.
  • In the process of prodsuction and handling, handle with care, try to avoid dragging or flipping the alloy aluminum sheet at will.
  • Arrange the aluminum sheets reasonably to avoid friction with each other as much as possible.
