As a material widely used in construction, decoration, transportation, aviation and other fields, the surface quality of Aluminum profiles has always been in the spotlight. However, in the process of production and use, Aluminum profiles are prone to scratches, which not only affects its aesthetics, but also may have an impact on its performance. So, how to remove scratches on the surface of aluminum profiles? This article will introduce you to some practical skills and methods.

First, physical methods to remove scratches

1. Sanding: the use of abrasives on the surface of the aluminum profile scratches grinding, so as to achieve a smooth effect. Sanding, you can choose the appropriate abrasives and abrasives, such as sandpaper, grinding wheels and so on. It should be noted that, in the sanding process to master the strength, to avoid secondary damage to the aluminum profile.

2. Polishing: Polishing is on the basis of sanding, using polishing machine and polishing agent on the surface of aluminum profiles to restore its brightness. When polishing, use the appropriate polishing agent, and adjust the polishing speed and pressure according to the material of the aluminum profile and the degree of scratches.

Second, chemical methods to remove scratches

1. pickling: pickling is a chemical reaction to remove scratches on the surface of aluminum profiles. Pickling, you can choose the appropriate pickling solution, such as sulfuric acid, hydrochloric acid and so on. It should be noted that the pickling time should not be too long, so as not to cause corrosion of aluminum profiles.

2. chemical polishing: chemical polishing is the use of chemical reactions to make the surface of the aluminum profile scratches at the local corrosion, so as to achieve the purpose of removing scratches. Chemical polishing, to choose the appropriate chemical polishing agent, and adjust the concentration and processing time in accordance with the instructions.

Third, other methods to remove scratches

1. laser repair: laser repair is a high-tech method, through the laser beam on the surface of the aluminum profile scratches for melting, so that it heals. Laser repair has the advantages of fast speed, high precision and small damage, but the cost of equipment is high.

2. electroplating: electroplating is a method of depositing a layer of metal on the surface of aluminum profiles to cover the scratches. When plating, choose the appropriate plating solution and metal, and control the current and time.

Summary: There are various methods to remove scratches on aluminum profiles, and you can choose the appropriate method according to the actual situation. In the process of removing scratches, pay attention to the intensity, time and temperature control to avoid secondary damage to the aluminum profile. At the same time, regular maintenance and maintenance of aluminum profiles is also an important measure to extend its service life.
