Aluminum composite panels have rich decorative effects and play a very important role. What are the advantages and disadvantages of aluminum composite.
1. Rich colors and strong decoration: the graphic layer of the aluminum composite panel can be made into various colors, and the pattern design matching all purposes can be carried out. The curtain wall decorated with aluminum composite panels is not inferior to the gorgeous glass curtain wall and elegant stone curtain wall. Under the sunlight, its layers are gorgeous and dignified, while avoiding light pollution. Compared with aluminum (or other metals) with the same rigidity or the same thickness, its mass is much smaller than that of glass and stone.
2. Good rigidity: The aluminum composite panel cleverly uses the mechanical principle of the I-beam structure, and ingeniously endows it with unique mechanical properties. Compared with the single-layer aluminum plate, its elastic limit is larger, and it is not easy to deform. Under the natural state of large external force, it can maintain good leveling performance for a long time.
3. Good durability: the aluminum composite panel adopts the thermal composite technology of metal and core material, and the bond is firm. The surface coating is made of different materials according to the different use environments. Generally, three types of coatings are used, namely fluorocarbon coatings and polyester coatings. , Acrylic coatings, among them, fluorocarbon coatings have more excellent weather resistance, and are mostly used in curtain wall decoration and special occasions. Experimental research shows that they can be used for more than 20 years in harsh outdoor environments.
First, the structure of the aluminum composite composite panel is generally three layers, with 0.1-0.5mm thick aluminum layers on both sides of the outside, and the sandwich material in the middle is mainly made of high-molecular materials such as medium and low-pressure polyethylene (high-density polyethylene). Vinegar glue bonding, the core material and glue contain toxic ingredients, and the performance of fire prevention, weather resistance, durability, and anti-aging is poor. When burning or high temperature, or even under the sun, it will release poisonous gas that is harmful to human health.
The second is that the composite strength is not high, and it is easy to break when the curved surface is bent. When the core material is locally heated, the core material will expand and cause the surface aluminum plate to deform and fall off. beautiful.
