Four quality problems in the aluminum -plastic panel curtain wall project 1. Discolor and discoloration of aluminum -plastic plates: aluminum -plastic plates produce discoloration and discoloration, mainly caused by 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 panels is generally used for anti -aging and strong anti -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. 2, aluminum plastic panels are turned on and off: aluminum plastic plates are turned on and off, mainly due to improper adhesives.
As an ideal adhesive for outdoor aluminum plastic board 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 of climate change, the phenomenon of opening and dehydration of plates appears. 3. Deformation and drumming on the surface of the aluminum plastic plate: The cause of the surface of the aluminum -plastic plate is deformation and drum.
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, is the aluminum -plastic plate as the surface layer that does not deform? 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.
4. Aluminum -plastic plate gum neat: Aluminum -plastic plates generally have a gap between the plates when the surface of the building is decorated. 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.
