What are the Common Problems of Aluminum Composite Panel Curtain Wall?

As a Perforated Metal Sheets Factory, share with you.

1. Discoloration and decolorization of aluminum-plastic panels

The discoloration and discoloration of aluminum-plastic panels are mainly caused by improper selection of panels. Aluminum-plastic panels are divided into indoor panels and outdoor panels. The surface coatings of the two panels are different, which determines their application in different occasions. The surface of the board used indoors is generally sprayed with a resin coating. This coating cannot adapt to the harsh outdoor environment. If used outdoors, it will naturally accelerate its aging process, causing discoloration and decolorization. The surface coating of outdoor aluminum-plastic panels generally chooses anti-aging and UV-resistant fluorocarbon resin coatings, which are expensive. Some construction units deceived the owners by using indoor panels as anti-aging and corrosion-resistant high-quality fluorocarbon panels to extract unreasonable profits, resulting in serious discoloration and decolorization of the aluminum panels used in the project.

2. Gluing and shedding of aluminum-plastic panels

The main reason that the aluminum-plastic panel is opened and peeled off is due to improper selection of the adhesive. As an ideal adhesive for outdoor aluminum-plastic panel projects, silicone glue has unique advantages. Now, when buying aluminum-plastic panels, the seller will recommend that kind of special quick-drying glue. This kind of glue can be used indoors, but when it is used outdoors where the climate changes, there will be the phenomenon of degumming and degumming of the board.

3. Deformation and drumming on the surface of the aluminum-plastic plate

There are many reasons for the surface deformation and bulging of the aluminum composite panel. In the past, this kind of quality problem occurred in the construction. We thought it was the quality of the plate itself. Later, after a concentrated analysis of everyone, we found that the main problem was the base plate of the aluminum-plastic plate, followed by the aluminum-plastic The quality of the board itself. Dealers often provide us with the construction process of aluminum-plastic panels, and the recommended base materials are mainly high-density boards, wood boards and the like. In fact, when this kind of material is used outdoors, its service life is very fragile, and it will inevitably be deformed after wind, sun, and rain. Since the base material is deformed, is there any reason for the aluminum-plastic panel as the surface layer to not deform? It can be seen that the ideal outdoor base material should be framed by angle steel and square steel pipe after anti-rust treatment. If conditions permit, it is more ideal to use aluminum profiles as the framework. The cost of the frame made of this kind of metal material is not much higher than that of wooden keel and high-density board, which can indeed guarantee the quality of the project.
