There are various types of membrane structure landscape materials used in membrane structure landscape engineering. Next, the Chuangguan editor will introduce PTFE membrane structure landscape materials to you.
PTFE membrane material is a material made by coating polytetrafluoroethylene resin on ultrafine glass fiber fabric. This membrane material has good welding performance, excellent UV resistance, aging resistance and flame retardancy.
Another characteristic of PTFE membrane structure landscape materials is that they have the best anti fouling and self-cleaning properties among all building membrane materials. However, on the contrary, they also have their own flaws, such as poor flexibility, difficult construction, and staggering costs.
Under the guidance of Geiger Company, DuPont, Corning Fiberglass, Baird Construction, and Chemical Fiber Weaving Company in the United States jointly developed permanent film materials. The processing method involves rapidly immersing fiberglass fabric into PTFE melt multiple times, resulting in a uniform PTFE coating on both sides of the fabric, thus giving birth to the permanent PTFE film. Subsequently, permanent membrane structure landscapes became popular in the United States, and many scholars conducted in-depth research on membrane structure landscapes.
After these membrane materials were put into use, the construction workers tracked and tested the results. The mechanical properties and chemical stability indicators of this membrane material only decreased by 20% to 30%, and the color remained almost unchanged. The surface of the membrane is smooth and elastic, and dust and chemical particles in the atmosphere are extremely difficult to adhere and penetrate. After being washed by rainwater, the building membrane can restore its original clean surface layer and transparency. This is enough to demonstrate the strong vitality and broad market prospects of PTFE membrane materials. Currently, PTFE membrane structure landscape materials are the most widely used membrane materials in membrane structure landscape engineering.
