Many friends may not know very well when using aluminum-plastic panels. What problems will it cause in our actual life? Here we will give you an introduction to relevant knowledge points. If you want to know Yes, you can take a look!
Discoloration and decolorization of plastic panels
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 usually sprayed with resin coating. This coating cannot adapt to the harsh outdoor natural environment. If it is used outdoors, it will naturally accelerate its aging process, causing discoloration and decolorization.
The surface coating of outdoor aluminum-plastic panels is generally made of polyfluoroelastomer coating with strong anti-aging and anti-ultraviolet ability, which is expensive. Some construction units deceive the owners, pretending to be anti-aging and anti-corrosion high-quality fluorocarbon plates for indoor use, and squeeze unreasonable profits, which has caused serious discoloration and decolorization of the aluminum plates used in the project. The seams of the aluminum-plastic panels are neat When aluminum-plastic panels are used to decorate the surface of buildings, there are generally gaps of a certain width between the panels.
For the sake of aesthetics, it is generally necessary to fill the gap with black sealant. In order to save time, some construction workers do not use paper tape to ensure the neatness and regularity of gluing when gluing, but use the protective film on the surface of the aluminum-plastic panel as a substitute. Since the protective film will tear to varying degrees when the aluminum-plastic panel is cut, it is impossible to tidy up the glue seams by using it as a substitute for the protective tape.
Ungluing and peeling of plastic panels The aluminum-plastic panels peel off and fall off, mainly due to improper selection of adhesives. As an ideal binder for outdoor aluminum-plastic panel projects, silicone glue has unique advantages. In the past, my country's silicone rubber mainly relied on imports, and its price discouraged many people. Only those expensive curtain wall projects on high-rise buildings dared to pay attention.
Now, my country's Zhengzhou, Guangdong, Hangzhou and other places have successively put into production different brands of silicone rubber, resulting in a sharp drop in prices. Now, when buying aluminum-plastic panels, the seller will recommend that special quick-drying glue. This kind of glue can be used indoors, but when it is used outdoors where the climate is erratic, the boards will be glued and peeled off.
Deformation and swelling on the surface of the aluminum-plastic panel If you walk around in any city, it is not difficult to find some projects that distort and bulge the surface of the aluminum-plastic panels. This phenomenon occurs in small facade decoration projects, and it also occurs in large high-rise buildings. In the past, this kind of quality problem occurred in the construction. We thought it was the quality of the board itself; later, after everyone’s concentrated analysis, we found that the main problem was the base board pasted with the aluminum-plastic board, followed by the aluminum-plastic board. The quality of the board itself.
Distributors often provide us with the construction technology 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 being exposed to wind, sun, and rain. Since the base material is deformed, is there any reason why the aluminum-plastic panel used as the surface layer does not deform? It can be seen that the ideal outdoor base material should be anti-rust treated, and the angle steel and square steel pipe should be formed into a skeleton.
If conditions permit, it is more ideal to use aluminum profiles as the skeleton. The cost of the skeleton 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. Generally speaking, these are some types of problems that will occur when we use aluminum-plastic panels. After the introduction of this content, you will understand it!.
