PU sandwich panel: an efficient and energy-saving building enclosure material
PU sandwich panel, also known as polyurethane sandwich panel, is an efficient and energy-saving building enclosure material that combines multiple excellent properties. It has been widely used and recognized in the field of modern architecture due to its unique structure and excellent performance.
The basic structure of PU sandwich panel is composed of two layers of glass steel plate inside and outside and a rigid polyurethane foam sandwich layer in the middle. The glass steel plates on both the inner and outer sides not only provide good mechanical strength and corrosion resistance, but also give the sandwich panel a beautiful and atmospheric appearance. The sandwich layer is made of rigid polyurethane foam, which is an excellent thermal insulation material with extremely low thermal conductivity and excellent thermal insulation performance. Made by high-pressure composite using German vacuum technology, PU sandwich panels not only have a compact structure, but also stable performance, ensuring thermal insulation during long-term use.
PU sandwich panels have a wide range of applications in the field of construction. Firstly, it is widely used in the exterior walls and roof enclosure systems of industrial plants, civil buildings, residential buildings, and other constructions. Due to its excellent thermal insulation performance, PU sandwich panels can significantly reduce the energy consumption of buildings and improve the comfort of living and working. At the same time, its fireproof, waterproof, non-toxic and odorless characteristics also ensure the safety of the building. In addition, PU sandwich panels are widely used in large public buildings such as sports venues, cinemas, exhibition halls, etc. due to their advantages of beauty, easy installation, and short construction period. These buildings often have higher requirements for space, insulation, thermal insulation, fire prevention, etc., and PU sandwich panels can precisely meet these needs.
In addition to its wide application in the construction field, PU sandwich panels also play an important role in refrigeration, dry cargo compartments, cold storage and other fields due to their unique properties. Its excellent thermal insulation performance can ensure the temperature stability of goods during transportation and storage, reducing energy consumption and losses.
The production process of PU sandwich panel is also very advanced. Adopting advanced sandwich panel continuous production line, it is formed by cold bending galvanized (aluminum zinc coated) color steel plates inside and outside, and coated with polyurethane rigid foam composite in the middle. This production process not only ensures the stable quality of sandwich panels, but also improves production efficiency and reduces production costs.
Overall, PU sandwich panel is a widely used and highly potential high-efficiency and energy-saving building enclosure material. It has been widely used and recognized in the field of modern architecture due to its excellent thermal insulation performance, beautiful and atmospheric appearance, easy installation, and short construction period. With the continuous progress of society and the increasing demand for environmental protection and energy conservation, PU sandwich panels will play a more important role in the future construction field.
