Door and window black technology has landed in the field of building energy conservation. The glass fiber reinforced polyurethane pultruded profile jointly launched by German materials leader and SHJR Advanced Materials Technology Group ranks among the world's energy conservation ranks. Recently, it was selected in the Shanghai Construction Association's 2020 "Demonstration Project Innovative Technology" It stood out in the event and was fully affirmed by the jury expert group and won the Innovation Technology Leadership Award.
In the SHJR Asia-Pacific R&D Center, we saw rows of glass fibers in the production line placed on the creel, and the polyurethane resin A and B components were placed in the closed injection machine. After heating and curing, the corresponding required lengths were obtained.
According to the person in charge of the company, the main door and window materials used in countries around the world are nothing more than aluminum alloy and PVC. PVC doors and windows are widely used in European and American markets, mainly because of their excellent thermal insulation properties. SHJR and German materials leader aim at market demand and use glass fiber reinforced polyurethane composite materials in the global door and window industry and composite materials industry to manufacture doors and windows. After several years of research and development and testing, mass production of glass fiber reinforced polyurethane composite door and window profiles was realized at the end of 2017. In addition to Vanke, Greenland, Shanghai Construction and other well-known real estate companies have chosen to apply, Lingang New City large-scale residential community and its supporting facilities, Shanghai Ninth People`s Hospital, West Bund Artificial Intelligence Conference Hall B, and multiple kindergartens and schools, etc. In cultural, educational and medical public buildings, it has been widely adopted for its excellent energy-saving and environmental protection performance, and has been recognized and praised by users.
Glass fiber reinforced polyurethane composites are light in weight, high in strength, and high in bending strength. They are 6 to 8 times that of aluminum alloy and 3 to 7 times that of steel. They are mainly used in lightweight automobiles, wind power blades, aerospace and other fields. Because of its excellent weather resistance, acid and alkali resistance, and salt spray resistance, it is widely used in harsh environments, such as seawalls, wind power, and ocean engineering. At the same time, polyurethane materials are widely used in all aspects of direct contact with the human body, including the medical field, and are recognized as safe and harmless materials with zero volatile components and can be used with confidence.
In the application of doors and windows, glass fiber reinforced polyurethane composite doors and windows are compared with broken bridge aluminum alloy and PVC plastic steel doors and windows, in terms of heat preservation, wind pressure resistance, air tightness, water tightness, sound insulation, fire prevention, corrosion resistance, etc. All aspects of performance have obvious advantages. At the same time, various coating treatments can be done on the surface of the profile, with rich effects. In contrast, glass fiber reinforced polyurethane doors and windows are more cost-effective than broken bridge aluminum and PVC plastic steel doors and windows.
Glass fiber polyurethane doors and windows have excellent fire resistance. With various fireproof glass, the fire resistance integrity can be achieved for 1 to 1.5 hours. It has the advantages of heat preservation and fire protection, which can be described as black technology for doors and windows. In terms of global glass fiber reinforced polyurethane composite production technology, SHJR relies on the advantages of the sound manufacturing industry chain in China, and the production of glass fiber reinforced polyurethane composite materials includes raw materials, molds, production equipment, coatings, processes and production technicians. They all have greater advantages than other countries. To this end, LG, Eagon, Deceuninck and other international companies in Japan, South Korea and Europe are conducting in-depth cooperation and exchanges with SHJR on glass fiber polyurethane profile pultrusion technology, trying to improve the original technology or introduce new Chinese production processes to the local area. , And the development of glass fiber reinforced polyurethane composite materials made by SHJR China has been recognized by the world.
