Aluminum-plastic composite panels have entered home decoration in recent years because of its smooth surface, colorful colors, strong impact resistance, easy cleaning, durability, and quick application. Aluminium-plastic panels are divided into two categories: exterior wall engineering boards and interior wall decoration boards. The latter is generally used for home decoration. Aluminium-plastic board is divided into two sides and one side. Double-sided aluminum plastic board surface are rust-proof high-strength aluminum alloy board. Front spray, reverse aluminum color. The single-sided aluminum-plastic panel has only one aluminum alloy plate on the surface, which is slightly less strong and the price is also lower. The quality of surface painting, good aluminum-plastic imported hot-pressure spraying process, uniform film color, strong adhesion, scratching is not easy to remove paint.
The aluminum plate used for home decoration is generally applied to the heating covers and partitions of restaurants, kitchens, bathrooms, and rooms. During construction, first the base of the plate should be dry and flat. It is better to use the multilayer board and blockboard as the bottom layer to prevent the occurrence of Cracking deformation. Secondly, when sticking aluminum-plastic composite boards, it must be noted that the adhesive must be evenly distributed. After the strong plastic thinner is volatilized, it can be affixed by touching it with a sticky hand and tapping with a wooden hammer. Third, the use of aluminum-plastic composite panels is divided into several pieces according to design requirements. Should not be used throughout the entire area or in large areas, or it may easily cause empty drums to open. Fourth, aluminum-plastic plate joints are generally sealed with glass glue. It is required that the glass glue be sealed and filled evenly. After drying, the surface should be cleaned to make the line thickness consistent.

The characteristics of aluminum-plastic panel Aluminium-plastic panel is a good material for easy processing and molding. It is an excellent product for pursuing efficiency and winning time. It can shorten the construction period and reduce costs. Aluminium-plastic panels can be cut, cut, grooved, band sawed, drilled, machined and countersunk, cold-formed, cold-folded, cold-rolled, riveted, screwed, or glued.
Common quality problems analysis
The discoloration and decoloration of the plastic-discolored and decolorized aluminum-plastic panel are mainly caused by improper selection of the panel. Aluminium-plastic panels are divided into indoor panels and outdoor panels. The surface coatings of the two panels are different, which determines their applicable different occasions. The plates used in the interior are generally coated with a resin coating. This coating cannot adapt to the harsh outdoor environment. If used outdoors, it will naturally accelerate its aging process and cause discoloration and discoloration. The surface coating of outdoor aluminum-plastic composite panels is generally made of anti-aging and anti-ultraviolet radiation-resistant polyfluoroelastomer coating, which is expensive. Some construction units deceived the owners to impersonate anti-aging and anti-corrosion high-quality fluorocarbon plates with indoor plates, and squeezed unreasonable profits. As a result, the aluminum plates used in the project were seriously discolored and discolored.
The opening of plastic panels, the removal of aluminum-plastic panels, and the loss of plastic panels are mainly due to improper use of adhesives. As an ideal binder for outdoor aluminum-plastic board engineering, silicone rubber has unique advantages. In the past, China's silicone rubber relied heavily on imports. Its price was deterred by many people, and only those curtain wall projects that were expensive on high-rise buildings were dare to pay attention. Now, China's Zhengzhou, Guangdong, Hangzhou and other places have put into operation different brands of silicone rubber, resulting in a sharp drop in prices. Now, when buying aluminum plastic board, the seller will recommend that kind of special quick-drying glue. This kind of glue can be used indoors, and it is used in the outdoor where climate change is not constant.
Aluminium-plastic plate surface deformation, drums casually stroll in which city in a circle, it is not difficult to find some aluminum-plastic plate surface deformation, drums that large landscape project. This phenomenon is reflected in the small facade decoration works, as well as in large high-rise buildings. Previously in the construction, there have been such quality problems, we once thought that the quality of the plate itself; later, after a concentrated analysis of everyone found that the main problem lies in the paste of aluminum plastic plate on the substrate, followed by aluminum plastic The quality of the board itself. Dealers often provide us with the construction process of aluminum-plastic panels. The basic materials that we recommend to use are mainly high-density boards, wood boards, and the like. In fact, when these materials are used outdoors, their service life is very fragile. After being blown by the wind, sun, and rain, they will inevitably undergo deformation. Since the grass-roots materials are all deformed, why is it that there is no distortion in the aluminum-plastic board as a surface layer? It can be seen that the ideal outdoor base material should be rust-proofed and angle steel and square steel pipes should be used as the skeleton. If conditions permit, the use of aluminum profiles as skeletons is even more desirable. The cost of the skeleton made of such metal materials is not much higher than that of wood keel and high density plates, which can really guarantee the quality of the project.
Aluminium-plastic panels glued neatly in aluminum-plastic panels When decorating the surface of a building, there is usually a gap of a certain width between the panels. For aesthetic needs, black sealants are generally filled in the gaps. In order to save time, some construction workers do not use paper tape to ensure the orderliness and rules of plastic injection. Instead, they use the protective film on the surface of the aluminum plastic panel as a substitute. As the aluminum-plastic board cuts, the protective film will produce different degrees of tearing, so use it as a substitute for the protective tape, it is impossible to neatly gather the glue.
