Scratches on the surface of aluminum plates are relatively easy to happen in the process of aluminum plate processing. It is often caused by improper processing, which leads to surface damage, which seriously affects the aesthetics of the aluminum plate. However, scratches have already appeared. Let’s introduce the surface scratch treatment of aluminum plates. method.
Scratches on the surface of the aluminum plate can be treated. Briefly, there are two methods: physical and chemical: the physical method is mechanical grinding, and the details include sandblasting, wire drawing, etc. This method is generally used for deeper scratches. The chemical method generally uses chemical reagents for polishing. In short, chemical reagents are used to corrode the surface of the aluminum material. Due to the sharp edges at the scratches, the corrosion rate is fast, and the lighter scratches can be completely eliminated after chemical polishing. , The chemically polished material has a bright appearance and looks good. Generally, the two methods are used together, and the appearance of aluminum can achieve a good decorative effect.
The solution to the scratches on the surface of the aluminum plate:

1. The working belt on the alloy aluminum plate mold needs to be polished smoothly, whether the empty knife of the extrusion mold is sufficient, and whether the surface is smooth.
2. In the process of producing alloy aluminum plates, pay attention to the generation of mold lines. Once the lines are produced, the mold needs to be removed in time to stop production.

3. In the process of aluminum plate sawing: each sawing needs to clean up the sawdust in time. Prevent secondary scratches.
4. Similarly, in the process of CNC machining aluminum plate, it is also necessary to prevent the residual aluminum slag on the fixture from being scratched.
5. There are exposed industrial aluminum profiles on the discharge track or swing bed or there are hard inclusions in the graphite strips. It is necessary to avoid scratches on the surface of the aluminum plate when the hard debris is in contact with the aluminum plate.
6. In the process of production and handling, it should be handled with care, and try to avoid dragging or flipping the alloy aluminum plate at will.
7. Arrange the aluminum plates reasonably and try to avoid mutual friction.

Nowadays, stainless steel plates have already become this kind of metal composite material that everyone can't leave in their daily life. Such raw materials can be used to make electrical equipment and daily necessities.

Aluminum plate installation and construction process disclosure

The aluminum veneer sheet is processed in the workshop. When the aluminum veneer is processed in the processing plant, the corner code and the aluminum veneer are connected, and they can be directly connected to the beam when transported to the site.
