Insulation aluminum plate performance understanding and understanding
ã€China Aluminum Industry Network】Production Benefits of Polyurethane Insulation Aluminum Panels External-wall polyurethane composite heat-insulating aluminum panels, with aluminum substrate as the outer substrate, are processed and designed according to the design, the surface is treated with the fluorocarbon coating recognized by the international construction industry, and the inner layer is hard. Polyurethane foam insulation, tightly bonded between inner and outer layers. With the characteristics of surface protection against rain, impact resistance, various colors, strong decoration, long service life, etc., it is a new type of high-grade exterior decoration material integrating insulation and decoration. The insulation aluminum panel is aesthetically pleasing, durable, beautiful, durable, and has good overall performance. For the first time, the problem of incombustible integration between insulation material and decorative surface material has been overcome. The heat-insulating material is closely combined with the decorative surface material, and it is not easy to fall off, loosen, and enhance the wind pressure resistance and flatness of the decorative surface material. Specifically have the following characteristics:
1, the structure of a new 2, light weight and excellent durability of this kind of aluminum sheet light, about 7kg per square meter of quality, its tensile strength of 200N/mm2; aluminum high elongation, relative elongation of more than 10%, can withstand the height Bent without cracking, good toughness.
3, decorative strong difference from other domestic and foreign insulation board structure, directly to the low thermal conductivity, high thermal insulation performance of rigid polyurethane by pouring foam firmly bonded to the back of the forming aluminum plate.
4. The weatherability of the coating is strong. The surface of the aluminum plate is sprayed with KYNAR-500 70% fluorocarbon polymer resin. After this fluorocarbon sprayed aluminum plate surface, the resistance to acid rain, corrosion, and UV resistance is extremely strong. Coatings do not fade, powder, or peel off for more than 20 years.
5, installation of fast process and reasonable insulation aluminum plate made in the factory line, directly to the construction site to hang on the envelope structure, is a new type of energy-saving decorative integrated high-grade exterior materials, and construction is convenient, short duration. In short, although polyurethane rigid foam can be ignited with open flame, it is not easy to burn. Even if it burns, it is only the surface of the coke and will not be burned.
6. The traditional practice of saving resources for building external walls requires the extensive use of cement, sand, water, and other materials, and the resources are very wasteful.
