Anti corrosion and thermal insulation aluminum coil is a product obtained after coloring the surface of aluminum coil. Its performance is stable and not easy to be eroded. Through special solutions, the surface layer can be guaranteed for decades and is widely used in all walks of life. What are the characteristics and surface white spot treatment of anti-corrosion and thermal insulation aluminum coil?
Characteristics of anticorrosive and thermal insulation aluminum coil
Painted into wood texture, it has a delicate physical sense and a fresh artistic beauty. Pattern design can be arbitrary, giving customers a universal and unique choice, enriching the historical and cultural significance of commodities, and giving everyone a beautiful enjoyment.
It adopts high-quality aluminum, plastic and adhesive, and adopts professional processing technology. It has the tensile strength required for decorative panels. Changes in air pressure, ambient temperature, environmental humidity and other factors will not cause bending, deformation or expansion of anti-corrosion and thermal insulation aluminum roll.
The surface layer has no composite continuous high-temperature stamping and residual stress, and will not deform after cutting.
It is resistant to salt, acid and rain erosion, is not easy to erode living bacteria, does not release harmful gas, and is not easy to erode the main keel and fixed components.
After continuous high-temperature baking, the paint lines still maintain high smoothness, good color stability and small color deviation. If polyester paint is used, it can be guaranteed for 10 years, and fluorocarbon spraying can be guaranteed for more than 20 years.
Anti corrosion and thermal insulation aluminum coil surface white spot treatment
The anti-corrosion insulation aluminum coil has strong metal activity and is easy to be oxidized. As the aluminum coating will produce a dense alumina film during oxidation, it can prevent continuous reaction with aluminum. Therefore, it should be normal for white spots to appear on the aluminum sheet. For aluminum sheet with strict surface requirements, how to avoid white spots on the surface and make the product more smooth and bright is not only related to the processing technology, but also closely related to the later surface treatment technology.
When large aluminum products are anodized, white spots occasionally appear on the surface after processing. The thermal insulation aluminum coating is especially obvious after oxidation. Insufficient washing after oxidation will lead to white spots on the dried surface. The solutions are as follows: strengthen cleaning after oxidation, and try to clean with a water gun. After cleaning, pay attention to protecting the surface, try to avoid contact with other products, and dry naturally.
Aluminum coil manufacturers believe that in order to control the white spots on the surface of aluminum sheet, they should not only pay attention to the surface problems of products before processing, but also pay attention to the prevention during surface treatment, and use strict standard processing processes and processes to avoid the formation of white spots. Acid and alkali washing can be used to clean the white spots, but the concentration or painting shall be controlled to block the contact between aluminum and oxygen.
