Polyurethane sandwich boards are an innovative building material that consist of two metal sheets and a polyurethane hard foam core material in the middle. Typically, the metal sheets are made of galvanized steel or color steel plates. This unique combination provides the sandwich board with the strength of metal sheets, as well as the exceptional performance of the polyurethane core material.
The polyurethane rigid foam core material is produced by mixing isocyanate and polyol under specific conditions. This results in a closed cell structure that is uniform and fine, which enhances the boards' insulation properties. The advanced production process of sandwich panels ensures that the layers are tightly combined, providing high-performance panels for construction applications.
Excellent Thermal Insulation Performance
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, so that the building can keep warm in winter and cool in summer, greatly reducing the energy consumption of the building and achieving energy saving and emission reduction.
Excellent Fire Resistance
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.
Good Water and Moisture Resistance
Polyurethane itself is a hydrophobic material, and its closed-cell structure also prevents water penetration. Coupled 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, avoid the problem of thermal insulation performance decline, mold, rot and other problems caused by moisture, and ensure the long-term stability of the thermal insulation system.
High Strength and Stability
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. At the same time, the polyurethane core material also gives the sandwich board a certain elasticity and toughness, so that it is not easy to deformation or damage when subjected to external forces, to ensure the stability of the building structure.
Excellent Sound Insulation
The polyurethane sandwich board has a good barrier effect on the transmission of sound, can effectively reduce the interference of external noise on the indoor environment, and create 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 the sound insulation performance of the thick and moderate density sandwich board is better.
Easy Installation Features
Polyurethane sandwich panels usually have standardized sizes and specifications, are relatively light in weight, and are easy to handle and install. At the construction site, a variety of 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.
Beautiful and Durable
The outer metal sheet can have a variety of colors and surface treatment methods, such as galvanized, color coating, etc., so that the sandwich board appearance is beautiful and generous, and can meet the needs of different architectural styles. At the same time, the metal sheet and polyurethane core have good durability, can resist the erosion of natural factors such as ultraviolet light, chemical substances, temperature changes, and extend the service life.
Polyurethane sandwich panels are versatile building materials that can be applied in various fields. The following are some of the common application fields:
Polyurethane sandwich panels are widely used in industrial plants, warehouses, logistics centers, and other buildings. In industrial plants, it can provide a stable temperature and humidity for the production environment, reduce heat exchange, heating and cooling costs, and meet the requirements of industrial production on building strength and fire performance. In warehouses and logistics centers, polyurethane sandwich panels protect goods from changes in temperature and humidity, ensuring quality.
Polyurethane sandwich panels are also used in commercial buildings such as shopping malls, supermarkets, hotels, office buildings, and other commercial places. In shopping malls and supermarkets, it helps maintain a comfortable indoor shopping environment and reduce energy consumption. In hotels and office buildings, it can provide good sound insulation, thermal insulation, and fire protection performance, creating a high-quality environment for customers and office workers.
Polyurethane sandwich panels are used for external wall insulation, roof insulation, and indoor partition of residential buildings. In the aspect of external wall insulation, it can effectively improve the residential thermal insulation performance and reduce energy consumption. In the insulation of the roof, it can protect the roof structure and extend the service life of the waterproof layer of the roof. When the indoor partition is used, it is both beautiful and can play a certain role in sound insulation.
The construction of cold storage is one of the important application fields of polyurethane sandwich panel. Its excellent thermal insulation performance can ensure the stability of the temperature in the cold storage, reduce the energy consumption of refrigeration equipment, and ensure the storage quality of refrigerated and frozen goods. At the same time, the moisture-proof and antibacterial properties of the sandwich panel are also conducive to maintaining the sanitary environment of the cold storage.
Polyurethane sandwich panels are also commonly used in agricultural greenhouses, agricultural products warehouses, and other facilities. In the greenhouse, it can adjust the indoor temperature, humidity, and light to create a suitable environment for crop growth. In the agricultural products warehouse, it can help maintain the freshness of agricultural products and extend storage period.
