Quality Analysis of Aluminum Composite Panel

Discoloration and discoloration of plastic board:

The discoloration and discoloration of Aluminum Composite Panel are mainly caused by improper selection of sheet materials. Aluminum-plastic board is divided into indoor board and outdoor board. The surface coatings of the two boards are different, which determines its different applications. The surface of the board used in the interior 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 and cause discoloration and discoloration. The surface coating of outdoor aluminum-plastic board is generally selected from the anti-aging and UV-resistant polyfluorocarbon coating, which is expensive. Some construction units have deceived the owners, posing as anti-aging and anti-corrosion high-quality fluorocarbon boards with indoor boards, squeezing unreasonable profits, and causing serious discoloration and discoloration of the aluminum boards used in the project.

Opening and peeling of plastic board:

The opening and peeling of the aluminum-plastic board is mainly due to improper selection of the binder. As an ideal binder for outdoor aluminum-plastic panel engineering, silicone glue has unique advantages. In the past, China’s silicone rubber mainly relied on imports, and its value was discouraged by many people. Only those expensive curtain wall projects on high-rise buildings dare to ask questions. Now, China’s Zhengzhou, Guangdong, Hangzhou and other places have successively put into production different types of silicone rubber, which has caused prices to plummet. Now, when buying aluminum-plastic panels, sellers will recommend that kind of special quick-drying glue. This kind of glue can be used indoors. If it is used outdoors with volatile climate, the board will open and peel off.

Deformation and bulging of the surface of aluminum-plastic board:

If you walk around in any city, it is not difficult to find some projects that are deformed and bulging on the surface of aluminum-plastic panels. This phenomenon appears on small facade decoration projects, as well as on large high-rise buildings. In the past, there were such quality problems in construction. We thought that it was the quality of the plate itself. Later, after everyone’s concentrated analysis, we found that the main problem was the base plate of the aluminum-plastic board, followed by aluminum-plastic. The quality of the board itself. Aluminum PVC Foamed Composite Panel Supplier often provides us with the construction process of aluminum-plastic panels. The recommended base materials are mainly high-density boards, wood board and the like. In fact, when such materials are used outdoors, their service life is very fragile. After wind, sun and rain, they will inevitably be deformed. Now that the base material is deformed, does the aluminum-plastic board as the surface layer have no deformation? It can be seen that the ideal outdoor base material should be rust-proofed and the angle steel and square steel pipe should be formed into a skeleton. If conditions permit, the use of aluminum profiles as the skeleton is even more ideal. The cost of a skeleton made of this type of metal material is not much higher than that of a wooden keel or high-density board, which can indeed ensure the engineering quality.
