Aluminum profile refers to aluminum alloy profile, while industrial aluminum profile belongs to alloy extrusion material. In the process of production and processing, it is easy to cause material damage and surface defects of the profile due to improper operation in one step. Under normal circumstances, the surface color of industrial aluminum profiles should be silvery white. Besides the rough and unsmooth surface, yellowing sometimes occurs.

Production and processing of aluminum profiles

The reasons for the surface yellowing of industrial aluminum profiles can refer to the following contents for specific analysis:

1. The profile needs to be cooled after being extruded by the die, in order to improve the mechanical and physical properties of the material. Coolant will be used in its cooling process, and the cooling effect of different materials is different. Common coolant is generally water or oily coolant. If water is used for cooling or when the copper content in the cooling liquid is relatively high, the surface of the profile will be yellowed. The reason for this is that the nature of aluminum, a metal, is relatively active, and it is easy to react with materials in air or water.

2. The surface of industrial aluminum profiles is usually covered with an oxide film, which can not only increase the corrosion resistance of profiles, but also increase the aesthetics of profiles. However, before the surface treatment of the profile, it is necessary to clean the surface of the extruded profile to fully remove the oil stain on its surface. If the cleaning work in this step is not in place, in the subsequent oxidation process, the oxide film will not be easily colored, or the coloring will not be uniform enough, resulting in yellowing.

Small knowledge of daily maintenance of popular science aluminum profiles by aluminum profile manufacturers and processors

Aluminum profiles can be seen everywhere in daily production and life, whether in the field of door and window curtain wall construction, or in the field of industrial aluminum profiles such as transportation, aerospace, machinery and equipment, advertising and decoration, municipal bridges, etc., they are all commonly used profiles with the characteristics of high strength, light weight, strong corrosion resistance, novel structure, convenient installation, material saving and durability. In the production and processing of aluminum profiles, attention should be paid to avoiding surface pollution. In order to ensure the practicality of aluminum profiles, it is necessary to maintain them during use to ensure their functionality and aesthetics.

Production and processing of aluminum profiles

During daily use and maintenance:

1. It is advisable to use soft cloth and towel to wipe the surface of aluminum profile. It is forbidden to use sandpaper, wire brush or other friction materials to scrub the surface of aluminum profile. Use warm water containing lubricant or neutral cleaning agent to clean it. Acid or alkaline cleaning agent shall not be used. If washing powder and strong acid and alkali cleaning agent cannot be used, the surface of aluminum profile will be easily corroded.

2. When the processed surface of aluminum profile is eroded and polluted, it should be cleaned in time. The scale can be scrubbed with soft cloth dipped in alcohol first, and then washed with clear water. After cleaning the aluminum alloy profile, the anodic oxide film can be polished with topcoat protective wax, or a layer of acrylate-based varnish can be sprayed evenly.

3. According to the use environment, the aluminum profile should be cleaned regularly to keep the brightness.

4. During the transportation and transfer of aluminum profiles, be extra careful, and handle them with care, so as to avoid the appearance bump caused by bumping; In the process of transportation, it must be covered with tarpaulin to prevent the invasion of rain; It is forbidden to load aluminum profiles loosely during shipment, so as to avoid the impact on the appearance of the profiles.

5. The storage environment of aluminum profiles should be dry and ventilated. When storing, the bottom of aluminum profiles must be separated from the ground with skids, and the distance between aluminum profiles and the ground should be more than 10CM. It is forbidden to register with chemical data and moisture data.

At the time of storage:

1. Keep away from sharp objects as far as possible. If there is a sharp object to scratch the industrial aluminum profile, it will definitely damage it, which will not only scratch the surface but also damage its performance.

2.clean the surface in time. If the industrial aluminum profile is caught in the rain for a long time, it will lead to traces later and needs to be cleaned in time.

3. industrial aluminum profiles need to be separated from the ground when stored, and there are separated plates. At present, most factories use shelves to store aluminum profiles.

4. Use neutral cleaning agent to clean. If there are stains on the surface that are not easy to clean, you should choose neutral cleaning agent to clean it to avoid damaging the oxide film on the surface, and wipe it off in time after cleaning. Take protective measures.

Everything needs to be maintained, and the aluminum profiles of industrial supplies should also be well maintained. I believe that through the finishing of the above small series, everyone has an understanding of the maintenance of aluminum profiles. The general surface of industrial aluminum profile products is anodized, which is very bright, wear-resistant, corrosion-resistant and easy to clean, so the service life can be extended if it is well maintained at ordinary times.
