Product Description
Product introduction
PU composite board is a polyurethane composite board, which is a new type of energy-saving board made of polyurethane as the core material and panels of different materials (such as color steel plate, aluminum plate, stainless steel plate, fiber cement board, etc.) on both sides of the composite through special processing. Polyurethane is a kind of high polymer, with high closed cell rate, excellent thermal insulation properties, etc., and different panels can be combined to make the composite board with a variety of excellent properties.
Product advantage
The thermal conductivity of polyurethane is extremely low, generally between 0.020-0.025W /(m · K), and the thermal insulation effect is more excellent than other common thermal insulation materials such as polystyrene, rock wool, etc., which can effectively reduce the heat transfer of buildings and reduce energy consumption.
1.Good waterproof performance: polyurethane itself is a hydrophobic material with a closed porosity of more than 90%, which can effectively block the penetration of water and maintain stable performance even in a humid environment, which can make the building have a good waterproof and moistureproof effect and extend the service life of the building.
2.High strength and light weight: PU composite board has a high strength to weight ratio, while ensuring the strength of the structure, the weight is relatively light, easy to handle, installation, can reduce the overall weight of the building, the bearing requirements of the building structure is low, especially suitable for the weight of the building parts, such as roof, wall and so on.
3.Excellent flame retardant performance: by adding flame retardants and other means, PU composite panels can reach different fire grades, such as B1 refractory, B2 flammable, etc., which can delay the spread of fire to a certain extent and improve the fire safety performance of the building.
Excellent sound insulation performance: polyurethane material has good sound absorption and noise reduction function, can effectively absorb and block sound transmission, can create a quiet and comfortable indoor environment for buildings, reduce external noise interference.
4.Beauty and durability: The composite panel has various materials, rich colors and high surface smoothness, which can be diversified selection and customization according to the architectural design needs, so that the building appearance is beautiful and generous. At the same time, the panel is closely combined with the polyurethane core material, which has good corrosion resistance and anti-aging properties, and can maintain good appearance and performance for a long time.
5.Convenient installation: PU composite board usually adopts standardized specifications and sizes and supporting connectors, and the installation process is simple and fast, which can greatly shorten the construction period, improve construction efficiency and reduce construction costs.
Product application
1.Industrial building field
Workshop: It can be used for the roof and wall of the workshop, which can provide good thermal insulation, waterproof and sound insulation for the workshop, meet the environmental requirements of industrial production, and its high strength can withstand the equipment load in the workshop and the pressure of the external natural environment.
Cold storage: Due to its excellent thermal insulation and waterproof performance, it is an ideal material for cold storage construction, which can effectively maintain the low temperature environment in the cold storage, reduce cold loss, and reduce operating costs.
2.Commercial building field
Shopping mall: It can be used for external wall decoration and internal partition of shopping malls, which can not only improve the overall beauty of shopping malls, but also play the role of heat preservation, sound insulation and fire prevention, and create a comfortable and safe shopping environment for customers.
Hotel: Used in the external wall of the hotel building, room partition and roof, etc., it can provide good thermal insulation and sound insulation performance, ensure the comfort of the room, and improve the quality and competitiveness of the hotel.
3.Public building field
Hospital: hospital wards, operating rooms, laboratories and other areas with high environmental requirements, PU composite boards can provide good thermal insulation, sound insulation and antibacterial properties, helping to create a quiet, comfortable and hygienic medical environment.
School: It is suitable for the roof and wall of the teaching building, library, gymnasium and other buildings of the school, which can provide good learning and activity space for teachers and students, and its environmental performance also meets the requirements of the school building.
4.Civil building field
Residential: It can be used as an integrated material for external wall insulation decoration of residential buildings, which can not only improve the thermal insulation performance of residential buildings, reduce energy consumption, but also make the appearance of residential buildings more beautiful and fashionable. In addition, it is also widely used in residential balconies, sun rooms and other parts.
Apartment: In the construction of apartment buildings, PU composite panels can be used for external walls, household walls and roofing and other parts, which can effectively improve the living comfort of apartments, and its convenient installation characteristics are also conducive to speeding up the construction progress and shortening the delivery time.
5.Other fields
Purification workshop: In electronic, food, pharmaceutical and other purification workshops with high environmental cleanliness requirements, PU composite board has good antibacterial, dustproof and thermal insulation properties, which can meet the special environmental requirements of the purification workshop and ensure the quality and safety of the production process.
Active board room: Because of its light weight, convenient installation, reusable characteristics, is one of the main materials of active board room, can be used for temporary office, living and other places of construction.
