First of allPunching aluminum veneerThe quality of aluminum profile is not entirely determined by the thickness, the key lies in the texture of aluminum profile. The surface treatment of perforated aluminum veneer includes electrostatic spraying, baking paint, roller coating, pearlescent roller coating, coating, etc. Among them, the service life of electrostatic spraying and baking paint is short, and color difference is easy to appear. The service life of rolling coating and pearlescent rolling coating plate is in the middle, and there is no color difference. Coated board can be divided into ordinary film and imported film. The service life of the common coating is lower than that of the roller coated plate, and the service life of the imported ceramic film can reach more than 20 years without discoloration.


Secondly, it is necessary to know the surface treatment technology of punching aluminum veneer. At present, it is usually treated with fluorocarbon spraying after chrome treatment. Polyvinylidene fluoride resin, fluorocarbon coatings, paints and varnishes. It is usually divided into two, three or four layers. At this stage, fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt fog and various air pollutants, has excellent cold resistance and heat resistance, can resist strong ultraviolet radiation, can fade and pulverize for a long time, and has a long service life. A kind of fluorocarbon spraying plate was proposed.

In addition, attention should be paid to punching aluminum veneer process. This process is the adhesion between sheet and surface, which is easy to ignore for customers. If the production process is not good, the service life of the product will be greatly affected. It is suggested that the manufacturer should be informed when selecting aluminum veneer.
