In modern architecture, PTFE membrane (polytetrafluoroethylene membrane) is increasingly used, and its unique properties and design flexibility have brought many innovations to the field of architecture.
The following are the main features and applications of PTFE membrane in modern architecture:
Material property
(1) Strength and durability
PTFE film material is known for its high strength and excellent durability. Its tensile strength can reach more than 7000 N/5cm, almost does not adhere to any dust, solid materials can not adhere to its surface, which makes it resistant to strong winds, snow and other bad weather.
(2) Weather resistance
PTFE film has excellent weather resistance, can be used for a long time in the temperature range of -180 ~ 260ºC, and is not affected by ultraviolet light, and has a long service life.
(3) Self-cleaning
Its surface energy is very small, non-viscous, so it has a good self-cleaning, can automatically clean the surface, reduce maintenance costs.
(4) Light transmittance
PTFE film has a high light transmittance, generally about 13%, which can make full use of natural light and reduce lighting energy consumption.
(5) Chemical stability
PTFE film can withstand in addition to molten alkali metals, fluorinated media and above 300℃ sodium hydroxide in addition to all strong acids including aqua royal, strong oxidants, reducing agents and various organic solvents, with high chemical stability.
Application advantage
(1) Light load and cost saving
The lightweight characteristics of PTFE film make it less of the load on the building structure, reducing the requirements for the building foundation and support structure, thus saving the construction cost.
(2) All-weather protection and natural lighting
The weather resistance and light transmission of PTFE film provide all-weather protection for the building, and make full use of natural light, reducing energy consumption.
(3) Beautiful shape
The softness and design flexibility of PTFE film allows it to create a variety of unique architectural shapes, adding beauty to modern architecture.
Application case
(1) Sports venues
For example, the 80,000 people Stadium in Shanghai and Al Janoub Stadium in Qatar, the PTFE membrane structure above the audience provides a large area of coverage space and ensures good lighting and ventilation.
(2) Commercial buildings
The Burj Al-Arab Hotel in Dubai, United Arab Emirates uses PTFE membrane structure, which is light and elegant, and has become a famous landmark building.
(3) Public facilities
China's Guangdong Foshan Century Lotus Sports Center, Hebei Cangzhou Gymnasium and other buildings also use PTFE membrane structure, providing the public with a comfortable and beautiful leisure space.
PTFE membrane has been widely used in the field of modern architecture because of its unique material properties and design flexibility. It not only provides strong protection and beautiful appearance for the building, but also saves construction costs and reduces energy consumption, in line with the concept of sustainable development.
With the continuous progress of technology and the continuous expansion of applications, PTFE membrane will play a more important role in the future of modern architecture.
