What are the commonly used membrane structural materials? The membrane structural materials commonly used can be classified into the following three categories:

1. PTFE membrane material

PTFE membrane material refers to a composite material formed by applying PTFE (polytetrafluoroethylene) resin on a substrate woven with extremely fine glass fibers. Its characteristics are: high strength, good durability, fire retardant, good self-cleaning, and not affected by ultraviolet light, with a service life of over 20 years; It has high transparency, with a transmittance of 13%, and the light passing through the membrane material is naturally diffuse, without producing shadows or glare; The reflectivity of solar energy is 73%, so it absorbs less heat, and even in the case of summer sun exposure, the interior of the building will not be greatly affected. At present, the development and application of this membrane material in foreign countries are relatively mature, and there are many manufacturers, such as Mehler Company and Verseidag Company in Germany, Taiyoko gyo Company in Japan, ZTE Chemical Industry Co., Ltd., Chemfab Company in the United States, ObeiKan Company in Saudi Arabia, and so on.

2. PVC membrane material

PVC film material is a composite material formed by applying PVC (polyvinyl chloride) resin on a polyester fiber woven substrate. The strength and fire resistance of PVC film material have a certain gap compared to PTFE, and its service life is generally 7 to 15 years. In order to solve the self-cleaning problem of PVC film materials, PVDF (polyvinylidene fluoride) is usually applied on the PVC coating to form a PVDF film material.

3. ETFE building membrane materials

The ETFE building membrane material is directly made of ETFE (ethylene tetrafluoroethylene copolymer) raw material. ETFE not only has excellent impact resistance, electrical performance, thermal stability, and chemical corrosion resistance, but also has high mechanical strength and good processing performance. In recent years, the application of ETFE membrane materials has shown strong advantages and market prospects by replacing other products in many aspects. This type of film material has excellent transparency, known as “soft glass”, and is lightweight, only 1% of the same size of glass; Good toughness, high tensile strength, less prone to tearing, and ductility greater than 400%; Strong weather resistance and chemical corrosion resistance, with a melting temperature of up to 200 ° C; Can effectively utilize natural light and save energy; Good acoustic performance. The self-cleaning function makes the surface less prone to dirt, and rainwater can wash away a small amount of dirt. The cleaning cycle is about 5 years. In addition, ETFE membranes can be pre fabricated into thin film bubbles, which is convenient for construction and maintenance. ETFE also has shortcomings, such as the external environment being prone to damage to materials and causing air leakage, and high maintenance costs. However, with the construction of large sports venues, tourist venues, waiting halls, etc., ETFE has highlighted its advantages. At present, there are very few companies producing this type of membrane material, and only a few companies such as ASAHIGLASS (AGC), Asahi Corporation of Japan, and Kewell of Germany can provide ETFE membrane materials. The research and application of this type of membrane material has only a history of more than ten years in developed countries abroad.
