In recent years, aluminum -plastic board has entered home decoration. Because of its smooth surface, colorful, strong impact resistance, convenient cleaning, solid and durable, construction is widely used. Aluminum -plastic boards are divided into two categories: outer wall engineering board and interior wall decoration board. Family decoration is generally used in the latter. Aluminum -plastic boards are divided into two and single sides.
The surface of the double -sided aluminum plastic board is the anti -rust high -strength aluminum alloy plate. Spray on the front, the back of the aluminum board. The single -sided aluminum plastic plate is only a layer of aluminum alloy plate on the surface, slightly worse, and the price is cheaper.
The surface of the paint is sprayed, and the good aluminum plastic uses the imported thermal pressure spraying process. The paint film has uniform color and strong adhesion. It is not easy to remove paint after bumping. Aluminum -plastic plates for home decoration are generally used in restaurants, kitchens, bathrooms and room heating masks, partitions and other shapes. During construction, first of all, the base surface of the board should be dry and flat. Cracking and deformation. Secondly, when paste the aluminum -plastic plate, pay attention to the glue. You must be evenly applied. When the powerful glue diluent volatilizes, it can be pasted by touching the hand without sticking hands.
Third, the aluminum -plastic plate is divided into several pieces according to design requirements. It should not be used in a large or large area, otherwise it is easy to cause empty drums. Fourth, the aluminum -plastic seams are generally seal with glass glue. It is required that the glass glue must be uniform and plump when it is sealed.
The characteristic of aluminum -plastic plates aluminum -plastic boards are easy to process and mold. It is also a good product that pursues efficiency and strives for time. It can shorten the construction period and reduce costs. Aluminum -plastic boards can be cut, cut, slot, saws, drilling, processing, and can be buried in cold, cold, cold rolled, and can also be riveted, screw connections or glue bonding.
Common quality problems analyze the discoloration of plastic panels and decocent aluminum plastic plates to produce discoloration and discoloration, mainly due to improper selection of plate materials. The aluminum plastic board is divided into indoor plates and outdoor plates. The surface coating of the two plates is different, which determines different occasions. The surface used in the room usually spray resin coating on the surface. This coating cannot adapt to the harsh natural environment of the outdoor. If it is used outdoors, it will naturally accelerate its aging process and cause discoloration.
The surface coating of outdoor aluminum plastic plates is generally used for polyfluorophilic coating with anti -aging and high -ultraviolet capacity. The price of this plate is expensive. Some construction units deceived the owners and impersonated high -quality fluorocarbon plates that were anti -aging and corrosion in the interior, squeezing unreasonable profits, which caused serious discoloration and discoloration of aluminum plates used in the project. Plastic plates are turned on and off the glue and drop -off of aluminum plastic panels, mainly due to improper adhesives.
As an ideal adhesive for outdoor aluminum plastic panel projects, silicone gel has unique and superior conditions. In the past, my country's silicone gums mainly rely on imports, and their worth of many people was discouraged. Only those high -rise buildings on high -rise buildings dared to ask for help. Now, Zhengzhou, Guangdong, Hangzhou and other places in my country have put into production of silicone gums of different brands, causing prices to plummet.
Now, when buying aluminum plastic panels, the sales provider will recommend the dedicated fast -drying glue. This kind of glue is still available indoors. For outdoor outdoor for climate change, the phenomenon of opening and falling off of plates appears. The deformation and drums on the surface of the aluminum plastic board will be traveled in which city, and it is not difficult to find some large scenery projects that deform and drum on the surface of aluminum plastic boards.
In this phenomenon of small facade decoration projects, there are also this phenomenon in large high -rise buildings. In the previous construction, this quality problem had occurred, and we once thought that the quality of the board itself; later, after everyone's centralized analysis, the main problem lies in the grass -roots plates of aluminum -plastic boards, followed by aluminum -plastic plastic. The quality of the board itself. Dealers often provide us with the construction process of aluminum -plastic boards. The recommended grass -roots materials they recommend are mainly high -density boards, woodworking boards and the like.
In fact, when used outdoors, this material is very fragile. After wind blowing, sun exposure, and rain, it will inevitably produce deformation. Now that the grass -roots materials are deformed, the aluminum -plastic plates that are used as the surface layer are the same as the non -deformation? It can be seen that the ideal outdoor grassroots material should be tied to skeleton by rust -proofing steel and square steel pipes. If conditions permit, aluminum profiles are more ideal.
The skeleton made of such metal materials is not much higher than the wooden keel and high -density plate, which can indeed ensure the quality of the project. When the aluminum -plastic plate is neatly neat aluminum -plastic plate, when the surface of the building is decorated, there are generally a certain width gap between the plates. For aesthetic needs, black sealing glue must be filled in the gap.
In order to save time, some construction personnel do not use paper gum to ensure that the glue is neat and regular, but instead use the protective film on the surface of the aluminum -plastic plate as a substitute. Because the aluminum -plastic plate is cut, the protective film will cause to tear to varying degrees, so it is not possible to use it to protect the tape alternative. Materials include: the main technical indicators of aluminum-plastic plates: coating thickness, gloss deviation, pencil hardness, adhesion, impact resistance, acid resistance, alkali, oil, solvent and other materials. Yuan Yi (1220x2440mm) is about 20-30 yuan per square meter, 3mm thick, and an artificial fee of about 0.05 mm in thickness of aluminum plate: Aluminum-plastic board ceiling includes wooden keel, digging light holes, mid-fiber plate base layer, aluminum-plastic plate adhesion (keels of keel (keels, keel (keels The spacing is 400-600mm) 18 yuan/square meter of the medium-sized light steel keels include shelves, lines, mixing materials, keel production installations, small ceiling high 3M for 11 yuan/square meter; wood keel 10 yuan/square meter.
The sealing surface of the wooden keel or light steel keel includes sealing plates, 4 yuan/square meter of wooden keel on the aluminum plastic plate layer of wooden keel, 4 yuan/square meter.
