Cutting-edge PU fiberglass pultrusion technology to apply aerospace materials to doors and windows and launch an epochal product——100% insulated PU fiberglass composite doors & widows system.
Have you ever had this kind of trouble? Whenever there is torrential rain, scorching heat, or cold, you can enter the room through the window, which seriously affects people's normal life and rest. It can be seen that it is particularly important to have a door and window with good heat insulation, sound insulation and air tightness, which can not only block haze and noise outside the window, but also save energy and reduce emissions to maintain the indoor temperature.
In recent years, building energy efficiency has become an important part of China's sustainable development. In buildings, doors and windows, exterior walls, roofs, and the ground are the four major parts of the building's energy consumption, of which doors and windows have the worst thermal insulation. SHJR Advanced Materials Technology Group and German materials leader jointly developed glass fiber reinforced polyurethane pultruded profiles.
What are glass fiber reinforced polyurethane pultruded profiles? It is a door and window profile produced through advanced injection dipping and pultrusion process with glass fiber as the reinforcing material and polyurethane as the matrix. The development of polyurethane door and window profiles is to provide high-rise buildings with energy-saving window solutions with a total heat transfer coefficient K ≤ 2.0 W/(m2•K). The raw material for the production of glass fiber reinforced polyurethane composite materials, polyurethane is petroleum-derived, and does not consume earth resources; according to the figures, the energy consumption of glass fiber reinforced polyurethane composite materials is only 1/60 of that of aluminum alloys, and the production process has no volatile components. , No industrial wastewater discharge; the finished product has good processing performance, convenient assembly, rich appearance, and no volatile components; and has a complete waste recycling system, grinding into a frame, etc., which can be recycled, which is really a building energy saving solution One of the options.
Recently, Hay Think experts walked into German materials leader and SHJR Asia-Pacific R&D Center located in Minhang Development Zone, Shanghai. They saw rows of glass fibers placed on the creel of the production line, and components A and B of polyurethane resin were placed on the creel. In the sealed injection machine, various products with different lengths are obtained after heating and curing. The person in charge of the company told us that 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. In China, the low production threshold of PVC profiles, coupled with the pressure of user procurement costs, has led to uneven quality of various PVC profile products. Various problems, such as deformation and water leakage, ultimately result in a poor reputation in the market of PVC plastic steel doors and windows, and it is difficult to be accepted among the high-end user groups. The aluminum alloy profile is very disadvantageous to energy saving due to the strong thermal conductivity of the metal material itself, and the cost remains high.
How to avoid their shortcomings? German materials leader and SHJR are aiming at the needs of the market, using 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, they have been widely adopted for their excellent energy-saving and environmental protection performance, and have been recognized and praised by users. It is worth mentioning that, recently, it stood out in the 2020 "Demonstration Project Innovative Technology" selection activity of the Shanghai Construction Association, and was fully affirmed by the evaluation expert group and won the Innovation Technology Leadership Award.
According to reports, the glass fiber reinforced polyurethane composite material is light in weight and high in strength. The bending strength is as high as 1442Mpa, which is 6 to 8 times that of aluminum alloy and 3 to 7 times that of steel. It is mainly used for lightweight cars, 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.
