Discoloration And Decolorization Of Aluminum-plastic Panels

The discoloration and decolorization of aluminum-plastic panels are mainly caused by improper selection of plates. Aluminum-plastic panels are divided into indoor boards and outdoor boards, and the surface coating of the two boards is different, which determines their application to different occasions. The surface of the plate used indoors is generally sprayed with resin coating, which can not adapt to the harsh natural environment outdoors, and if it is used outdoors, it will naturally accelerate its aging process and cause discoloration and decolorization. The surface coating of outdoor aluminum-plastic panels is generally made of anti-aging, anti-ultraviolet ability of polyfluorocarbon coating, which is expensive. Some construction units deceive the owner by using indoor plates to impersonate anti-aging, anti-corrosion high-quality fluorocarbon plates to extract unreasonable profits, resulting in serious discoloration and decolorization of aluminum plates used in the project.
