PTFE architectural membrane
August 15, 2023
The PTFE membrane is a material obtained by coating a polytetrafluoroethylene fabric with a polytetrafluoroethylene resin. This film has good welding performance, excellent UV resistance, aging resistance and flame retardant properties. In addition, its anti-fouling and self-cleaning properties are the best among all architectural membranes, but the flexibility is poor, the construction is difficult, and the cost is also amazing. Under the leadership of Geiger, DuPont, Corning Fiberglass, Baird Construction, and Chemical Fiber Weaving Co., Ltd. jointly developed permanent membranes. The processing method is that the glass fiber fabric is quickly placed into the Teflon melt multiple times, so that the fabric has uniform Teflon coating on both sides.
The 486 square layer of Dameisha Sports Park night scene, the permanent PTFE film was officially born. Since then, permanent membrane structures have been officially popular in the United States, and many scholars have conducted in-depth research on membrane structures. After 20 years, the results of tracking and testing showed that the mechanical properties and chemical stability indexes of this film only decreased by 20%~30%, the color was almost unchanged, the surface of the film was smooth, elastic, and dust and chemicals in the atmosphere. Particles are extremely difficult to adhere and penetrate, and the building membrane can be restored by rain to restore its original clean surface layer and light transmission, which is enough to show the strong vitality and broad market prospect of PTFE membrane. At present, the development and application of such membranes are relatively mature abroad, and there are many manufacturers, such as Mehler, Verseidag, Japan, Taiyoko-gyo, Zhongxing Chemical Industry Co., Ltd., Chemfab, Saudi Arabia, ObeiKan, etc.
