Most of the current parking sheds are of membrane structure, Membrane structure parking shed There are many kinds of materials selected. The main material is membrane material. What are the other materials?
The membrane structure parking shed also includes expanded PTFE construction membrane materials, ETFE construction membrane materials, glass fiber PVC construction membrane materials, glass fiber silicone resin construction membrane materials, glass fiber synthetic rubber construction membrane materials. What are the functions of these materials? Expanded PTFE construction membrane material is made by pasting fluororesin film on the base cloth woven from expanded PTFE fiber on both sides. Because its cost is too high, and the cost and function are considered in general construction, this kind of membrane material is rarely used. At present, there are few foreign manufacturers.
ETFE construction membrane material is directly made of ETFE (ethylene tetrafluoroethylene copolymer) raw material. This film material not only has excellent impact resistance, electrical function, thermal stability and chemical corrosion resistance, but also has high mechanical strength and good processing function.
Glass fiber PVC construction membrane is developed and applied earlier. Generally, the thickness of PVC coating on the intersection of warp and weft of glass fiber fabric shall not be less than 0.2mm. Generally, the coating shall not be too thick, and it can meet the application requirements. Glass fiber silicone resin construction membrane material has the characteristics of silicone resin, such as excellent high and low temperature resistance, water repellency, oxidation resistance, etc. This membrane material has high tensile strength and elastic modulus. Other membrane structure parking sheds have good light transmittance and are easy to manufacture. The synthetic rubber (such as nitrile rubber and chloroprene rubber) of the glass fiber synthetic rubber construction membrane material has good resistance to sunlight, ozone and heat aging, excellent abrasion resistance, chemical resistance and flame retardancy, and can reach the translucent state. However, because of its simple yellowing, it is generally used for dark coatings.
