1, aluminum plastic plate discoloration, decolorization
Aluminum - plastic plate discoloration, decolorization, mainly due to the selection of improper plate caused. Aluminum plastic plate is divided into indoor plate and outdoor plate, the surface coating of the two kinds of plate is different, which determines its application in different occasions. The surface of the indoor curtain wall panel is generally sprayed with resin coating, which cannot adapt to the harsh outdoor natural environment. If it is used outdoors, it will naturally accelerate the aging process and cause the phenomenon of discoloration and decolorization. The surface coating of outdoor aluminum plastic board is generally fluorocarbon resin coating with strong anti-aging and ultraviolet resistance, which is expensive. Some curtain wall manufacturers cheat owners, with indoor plate posing as anti-aging, anti-corrosion high-quality fluorocarbon plate, extract unreasonable profits, resulting in serious discoloration and decolorization of the aluminum plate used in the project.
2. Gluing and peeling of aluminum plastic plate
Aluminum - plastic plate gluing, falling off, mainly due to improper selection of adhesives caused. As an ideal adhesive for outdoor aluminum-plastic plate engineering, silicone adhesive has unique superior conditions. In the past, our silicone glue mainly depends on imports, and its price makes many people flinch. Now, Zhengzhou, Guangdong, Hangzhou and other places have put into production of different brands of silicone glue, causing the price to plunge. Now, in the purchase of aluminum plastic plate, the seller will recommend that special quick - drying glue. This kind of glue can be used indoors, and it can be used outdoor curtain wall construction when the climate changes impermanently.
3. Deformation and drumming on the surface of aluminum plastic plate
The causes of surface deformation and bulging of aluminum - plastic plate are various. Before in the construction, there has been this quality problem, we used to think that is the reason for the plate itself. Later, after everyone's concentrated analysis, it was found that the main problem lies in the paste of aluminum plastic plate on the base plate, followed by the quality problem of aluminum plastic plate itself. Dealers often provide us with the construction technology of aluminum plastic board, and the recommended base materials are mainly high-density board and woodworking board. In fact, when this kind of material is used outdoors for the modern curtain wall, its service life is very fragile. After wind, sun and rain, it will inevitably produce deformation. So we should pay more attention to the curtain wall materials.
