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.
1, the structure of a novel, decorative strong difference from other domestic and foreign insulation board structure, directly to the low thermal conductivity, high thermal insulation properties of rigid polyurethane by pouring foam firmly bonded to the back of the forming aluminum plate. Polyurethane insulation thickness can be designed according to the temperature of different regions. After industrial processing and molding, dry hanging is used to fix the main structure. The polyurethane composite heat insulation aluminum plate and the main structure are firmly connected to form a variety of decorative effect of the external wall. The aluminum plate is processed and shaped, and then treated with fluorocarbon. The surface of the aluminum plate is clean and smooth. The computer is used for color matching. The color is elegant, beautiful and elegant, and it is not easy to stick dust, and can achieve the ideal beautifying environmental effect. A series of problems such as heat preservation, exterior wall decoration, service life, and cracking of the envelope structure are solved in one-time. Heat-insulating aluminum plate 3. Coating weatherability The surface of the aluminum plate is sprayed with fluorocarbon polymer resin containing KYNAR-500 up to 70%. The fluorocarbon sprayed aluminum surface has reached the current US AAMA 60.5.2.92 quality standard. Anti-acid rain, anti-corrosion, anti-ultraviolet ability is very strong, can guarantee the coating does not fade, not powder, does not fall off for more than 20 years.
4, light weight, excellent durability and light weight This type of aluminum plate is 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 high bending without cracking Good toughness. The interior is filled with rigid polyurethane, and the board is firmly fixed on the keel to form the entire wall, which greatly reduces the load on the building structure. Can withstand general collisions, plate temperature deformation stress can be adjusted by the interstitial joints to absorb, it is very strong. With Stainless Steel bolts, it will not corrode, and it can have the same life as the main structure.
5. The traditional practice of resource conservation building external walls requires the use of large quantities of cement, sand, water, and other materials. The resources are very wasteful. After the demolition, there is a lot of waste. The external wall insulation aluminum plate is a resource that can be recycled, reused, and used for a certain number of years. After the building is dismantled, the aluminum sheet can be reprocessed into other aluminum products through recycling processing. After the polyurethane board is broken, it can be processed into aggregates of thermal insulation materials to become renewable energy, save limited national resources, and follow the sustainable development production model.
6, the installation of rapid process and reasonable insulation aluminum plate made in the factory line, directly to the construction site directly hanging on the envelope structure, is a new type of energy-saving decorative integrated high-grade exterior materials, and construction is convenient, short duration. 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. The color of the decorative surface is diversified, and can be processed into a variety of plate shapes, which can better reflect the personality of the building decoration. Fire, fire, fire resistance performance is greatly improved Polyurethane foam is a thermosetting plastic, will not be melted by high temperature, only the formation of less smoke, strong resistance to ignition hole char and flame spread; its potential value is also very high Fewer, density 38Kg/m3, thickness 50mm polyurethane rigid foam only 53MJ/?; flammable weight of the potential impact on combustion is small, and thus the ability to promote fire is also very small; in case of fire or high temperature, its excellent thermal insulation performance, only The surface is rapidly heated up, rapidly coked to resist flame spread, and the inner core is protected from combustion, showing good fire-proof performance. The rest of the residue is a hole-shaped carbon-containing char and maintains its original physical shape, which prevents heat transfer, resists the spread of fire and heat, and does not collapse causing secondary disasters. 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.
These are all in line with the building fire and fire resistance requirements, and are excellent new building materials products. Double-insulation improvement performance After a relatively new test, an aluminum foil is attached to the upper mold of the polyurethane foam. After the foam molding, the aluminum foil functions as a release agent, and the other side is attached to the foam body to reinforce the aluminum plate. Wind pressure strength. Aluminum foil, polyurethane double insulation, better. Atlas of the full set of data, standards, technical regulations and standards formed a series of specification documents during the use of research and pilot projects, including test reports, material standards, production and processing technology standards, production equipment use procedures, product inspection procedures, and materials Field re-inspection procedures, construction technical regulations, construction standards atlas and engineering acceptance procedures. Can significantly reduce the construction cost of the traditional external insulation structure insulation practices, the use of large quantities of water, cement, sand and other Ali this, with some mechanical equipment and construction scaffolding, and winter is difficult. The use of polyurethane composite insulation aluminum panels for thermal insulation of enclosures, a one-time solution to the exterior and insulation use, can be dry directly on the frame or steel frame, without cutting the wall, no construction water, sand resources, there is no winter In addition, the thickness of the retaining wall can be reduced, and the area of ​​use of the house can be increased, and the thermal performance can reach the energy saving standard and the unit building cost of the building can be reduced.
