Polyurethane composite board, as a building energy saving and thermal insulation material, has been widely used in Europe, the United States, Japan and other developed countries, with a penetration rate of 80%, less than 10% in China. As an excellent
energy saving and heat preservation material, polyurethane sandwich board can provide efficient solutions to China's energy consumption crisis with its excellent heat insulation, fire prevention and heat preservation performance.
Polyurethane sandwich panels are widely used in large industrial plants, cold storage, garages, mobile houses, exhibition halls, exhibition halls, gymnasiums, shopping centers, airports, power plants, villas, hospitals, stratum and high-rise office buildings
and other fields. Due to their excellent thermal insulation performance, they are mainly used in the roofing and wall of industrial and civil buildings. Sandwich against leaking roof panel, polyurethane rigid foam insulation board, polyurethane composite
panels, PU board, is the popular term polyurethane sandwich board, strictly speaking, should be used in polyurethane thermal insulation sandwich board, conforms to the national standard GB/T 23932-2009, the product is rigid polyurethane as the thermal
insulation layer of double metal surface, sheet metal, non-metallic surface composite plate, usually used in industrial workshop, integrated logistics, warehousing, walls, roof containment system of the building.
When the bonding strength of polyurethane
sandwich panel is not less than 0.09mpa, the combustion performance of sandwich panel reaches Class B1, and the flexural capacity of sandwich panel is Lo/200(Lo is the distance between the supports), the flexural capacity of sandwich panel is not less
than 0.5kN /m2. The effective width of the sheet is usually 1000mm and the length can be customized.
The production of polyurethane sandwich board requires an advanced continuous production line, and the process is formed by cold bending of internal
and external galvanized (aluminum-zinc plated) colored steel plate, and compounded by polyurethane hard foam coating in the middle. The use of patented leak-proof sandwich roofing board is to give full play to the advantages of polyurethane sandwich board.
This product has the following characteristics:
1) Thermal conductivity low polyurethane sandwich composite board has low thermal conductivity and good thermal insulation performance, so it is the best thermal insulation material at present.
2) Beautiful plate shape and convenient installation
3) Polyurethane sandwich board has good fire resistance
4) Polyurethane sandwich board is non-toxic and tasteless
5) Wide range of temperature
6) waterproof, moisture proof
polyurethane sandwich panel beautiful shape, the overall effect is good, it integrating bearing, thermal insulation, fire prevention, waterproof, without secondary decoration, convenient installation, short construction period, good comprehensive benefits,
have good price advantage, is a kind of widely used, potential energy efficient building palisade materials, it is advocated by the ministry of construction and promotion of a new type of energy-saving plates.
