Aluminum Corrugated Panel Wholesaler Introduces Precautions for the use of aluminum composite panels :
1. The discoloration and discoloration of aluminum composite panels are mainly caused by the 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 on different occasions. The surface of the board used indoors is generally sprayed with a 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 discoloration. The surface coating of the outdoor aluminum composite panel 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 sheets for indoor use, to squeeze unreasonable profits, thus causing serious discoloration and discoloration of the aluminum sheets used in the project.
2. The glue seams of the aluminum-plastic panels are neat. When the aluminum-plastic panels are used to decorate the surface of the building, there are generally gaps of a certain width between the plates. For the sake of beauty, the black sealant is generally filled in the gap. In order to save time when gluing, some construction workers do not use paper tape to ensure the neatness and rules of gluing but use the protective film on the surface of the aluminum composite panel as a substitute. Since the protective film will be torn to varying degrees when the aluminum composite panel is cut, it is impossible to tidy up the glue seam by using it as a substitute for protective tape.
3. The glue opening and falling off of the aluminum composite panel are mainly due to the improper selection of the binder. As an ideal binder for outdoor aluminum composite panel projects, silicone adhesive has unique advantages.
4. Deformation and bulging on the surface of aluminum-plastic panels. If you walk around in any city, it is not difficult to find some projects that deform and bulge on the surface of aluminum-plastic panels. This phenomenon occurs in small facade decoration projects, as well as in large high-rise buildings. In the past, this kind of quality problem occurred in the construction, and we thought it was the quality of the board itself; later, after everyone's concentrated analysis, it was found that the main problem was on the base plate of the aluminum-plastic board, followed by the aluminum-plastic board. The quality of the board itself. Dealers often provide us with the construction technology of aluminum-plastic panels, and the recommended base materials are mainly high-density boards, woodworking boards and the like. In fact, when this type of material is used outdoors, its service life is very fragile, and it will inevitably deform after being blown by wind, sun, and rain. Since the base material has been deformed, then there is no reason for the aluminum composite panel as the surface layer to be deformed? It can be seen that the ideal outdoor base material should be treated with anti-rust treatment and then formed into a skeleton with angle steel and square steel pipe. If conditions permit, it is more ideal to use aluminum profiles as the skeleton. The cost of the skeleton made of such metal materials is not much higher than that of wooden keels and high-density boards, which can indeed ensure the quality of the project.
