Polyurethane sandwich board is an innovative building material that combines the strength of metal sheet and the excellent performance of polyurethane core material. It consists of two layers of metal sheet, typically galvanized steel plate or color steel plate, with a layer of polyurethane hard foam core material in the middle.
Polyurethane rigid foam core material is produced by mixing isocyanate and polyol under specific conditions. This creates a uniform and fine closed cell structure inside, which adds to the material's durability and insulation properties.
The production process of polyurethane sandwich boards is advanced, ensuring that the layers are tightly combined to create a durable and strong structure. These high-performance panels can be used for various construction applications, making them a preferred choice among builders and contractors.
The thermal conductivity of polyurethane is extremely low, generally between 0.018-0.024 W/(m · K), which is much lower than other traditional insulation materials. This low thermal conductivity benefits from the closed cell structure of polyurethane, which effectively reduces the heat conduction, convection and radiation. As a result, the building can maintain warm temperatures in winter and cool temperatures in summer, reducing energy consumption significantly. It also helps in energy saving and emission reduction.
By adding appropriate flame retardants, polyurethane sandwich panels can achieve different fire ratings, such as B1 (flame retardant) or even A2 (non-flammable). In the event of a fire, it can effectively delay the spread of the fire, inhibit the spread of the flame, reduce heat release and smoke generation, gain valuable time for personnel evacuation and fire rescue, and improve the fire safety of the building.
Polyurethane itself is a hydrophobic material. Its closed-cell structure prevents water penetration. With the protection of the outer metal sheet, the sandwich board can effectively resist the erosion of rain, snow and humid air, prevent water from entering the interior of the temperature retaining core material, and avoid the problem of thermal insulation performance decline, mold, rot, and other problems caused by moisture. This ensures the long-term stability of the thermal insulation system.
The upper and lower layers of sheet metal provide enough strength for the sandwich board to withstand large external forces, such as wind loads, snow loads, and the weight of personnel and equipment. The polyurethane core material also gives the sandwich board a certain elasticity and toughness to ensure stability of the building structure and avoid deformation or damage due to external forces.
The polyurethane sandwich board has a good barrier effect on the transmission of sound. It can effectively reduce the interference of external noise on the indoor environment, creating a quiet and comfortable living and working space for people. The sound insulation effect depends on the thickness and density of the sandwich board to a certain extent, and thicker and moderate density sandwich boards have better sound insulation performance.
Polyurethane sandwich panels usually have standardized sizes and specifications, are relatively light in weight, and easy to handle and install. At the construction site, various installation methods can be used, such as splicing, anchoring, etc. The installation process is simple and fast, which can effectively shorten the construction period and reduce the construction cost.
The outer metal sheet can have a variety of colors and surface treatment methods, such as galvanization, color coating, etc., making the sandwich board visually pleasing and suitable for different architectural styles. The metal sheet and polyurethane core have good durability, capable of resisting the natural factors such as ultraviolet light, chemical substances, temperature changes, and extending the service life of the sandwich board.
Polyurethane sandwich panels have diverse application fields in various buildings and facilities. Some of the application fields are:
Polyurethane sandwich panels have various applications in industrial buildings such as warehouses, logistics centres and industrial plants. They enhance the production environment by providing stable temperature and humidity conditions, and reducing heat exchange hence leading to a reduction in heating and cooling costs. They also meet the requirements of fire protection and building strength. In addition, polyurethane sandwich panels protect goods from changes in temperature and humidity in warehouses and logistics centres.
Polyurethane sandwich panels are used in commercial buildings like shopping malls, hotels, office buildings and supermarkets. They create a comfortable indoor shopping environment and help in reducing energy consumption in shopping malls and supermarkets. In hotels and office buildings, the panels provide sound insulation, thermal insulation, and fire protection performance, creating a high-quality environment for customers and workers.
Polyurethane sandwich panels are used for external wall insulation, roof insulation, and indoor partition in residential buildings. They effectively improve the thermal insulation performance of the residential buildings and reduce energy consumption in external wall insulation. They protect the roof structure and extend the service life of the waterproof layer of the roof in roof insulation. When used in indoor partition, they are both aesthetically appealing and provide a certain degree of sound insulation.
Polyurethane sandwich panels are used in cold storage, one of the most important applications of polyurethane sandwich panels. They have excellent thermal insulation properties that ensure temperature stability, hence reducing energy consumption of refrigeration equipment and ensuring storage quality of refrigerated and frozen goods. The moisture-proof and antibacterial properties also help maintain the sanitary environment of the cold storage.
Polyurethane sandwich panels are also used in agricultural facilities such as agricultural greenhouses and agricultural products warehouses. The sandwich panels help adjust the indoor temperature, humidity, and light to create a suitable environment for crop growth in agricultural greenhouses. The freshness of agricultural products can be maintained, and the storage period can be extended in agricultural products warehouses.
