ETFE is called ethylene tetrafluoroethylene in English and ethylene tetrafluoroethylene copolymer in Chinese, commonly known as F-40. ETFE is a tough fluoroplastic. It adheres to the outstanding heat resistance, chemical resistance and electrical insulation functions of PTFE, which together improve radiation resistance and mechanical functions to a large extent. The tensile strength can reach 50 MPa, close to that of polymer. It is twice as high as tetrafluoroethylene.
PVDF membrane:
Polyvinylidene fluoride, abbreviated as PVDF, mainly refers to homopolymer of vinylidene fluoride or copolymer of vinylidene fluoride and a few other fluorinated vinyl monomers. In addition to outstanding chemical resistance, high temperature resistance, oxidation resistance, weather resistance and radiation resistance, it also has the characteristics of fluororesin and general resin, and also has special functions such as piezoelectricity, dielectric property and weather resistance..
In fact, the shape of the building should be proposed by the constructor, but the membrane structure has the problem of shape finding, so the constructor often requires the structural engineer to determine. However, shape finding is not unique. Different internal force distribution will find a different building shape, and different shapes will directly affect the role of building. It is worth mentioning that different building shapes may directly affect the economy of the project. Because some shapes are difficult to complete, perhaps requiring greater prestress, the problem is the difficulty of using more materials and construction technology. Therefore, the reasonable construction shape should be determined by the cooperation of the structural engineer and the constructor. Membrane structure landscape
Membrane structure parking shed The mechanism system is composed of the tensile stress of the membrane itself, the supporting rod and the cable. Under the sunlight, the building covered by the film is filled with natural diffuse light, without strong contrast between the lighting surface and shadow, and the indoor space visual environment is open and harmonious. At night, the lights in the building illuminate the night sky through the membrane of the roof, and the shape of the building shows a dreamlike effect.
Manufacturer of membrane structure parking shed The planning and construction of parking lots have become an important part of modern urban planning, becoming more and more important. The light and special shape of the membrane structure plays an important role in the construction of the parking lot and waiting hall. In addition to meeting the basic functions of weatherproof and sun proof, it also has a good role in attracting signs, showing the personalized side of people.
Application: due to the emergence of high-strength membrane materials and the application of tensioning technology, the ability of membrane structure shed to resist wind and rain is incomparable with that of ordinary awnings. Some sheds are made of durable membrane materials, which can be used for 30 to 40 years. Especially when encountering severe storm climate, the membrane structure is built firmly without damage.
Artistic: In addition to the usefulness, durability and function of shielding the wind and rain of ordinary awnings, the membrane structure awning is a sculpture, a work of art, giving people beautiful visual enjoyment. Its softness, its curves, its hardness and softness, its rich shapes, its white and flawless, make people look bright and have a long aftertaste.
