5A02 aluminum plate china in the process of transportation or processing, if the surface is accidentally scratched, etc., how to eliminate it? Here's to you:

1. Physical polishing, that is, mechanical polishing, specifically sandblasting, wire drawing, etc., this method is generally used for deeper scratches;

2. Chemical polishing is used for surface treatment, such as oxidation treatment. Chemical reagents can corrode a layer of aluminum surface. Due to sharp edges at scratches, the corrosion rate is fast, and lighter scratches can be completely eliminated after chemical polishing. The chemically polished material has a bright surface and looks good.

In this way, through the combination of physical and chemical methods, the surface of the aluminum material can achieve a good decorative effect, and the general scratches can also be removed.

In order to avoid excessive scratches on the surface of 5A02 aluminum plate china, how to prevent it?

1. The surface of 5A02 aluminum plate china is covered with protective film, which can well avoid electrostatic shock during transportation and scratches during processing;

2. Paper is sandwiched between 5A02 aluminum plate china, so that friction between 5A02 aluminum plate china can also be avoided during transportation.
