Building membrane building has the following characteristics:
(1) light weight, the cost is relatively low; the large-span structure building with this material is an order of magnitude lighter than the traditional structure, and the basic cost can be reduced by more than 50%.
(2) good self-cleaning and aging resistance; the coating of membrane structure material has high anti-corrosion and weather resistance, excellent self-cleaning, can reduce ultraviolet radiation, and can withstand large
range of temperature fluctuations.
(3) The structure span is large; the membrane structure has light weight, which can create a large area of non-pillar covering space that cannot be achieved by traditional structures.
(4) It has translucency and high energy efficiency; the film structure material itself has good light transmittance, and the light transmittance is about 15%, which can make full use of natural light.
(5) beautiful shape, full of flavor of the times; membrane structure building breaks through the traditional architectural structure form, easy to make a variety of shapes, in the light with easy to form a wonderful night
Scenery, giving people a feeling of modern beauty.
(6) There are also the advantages of safe and reliable use, good seismic resistance, and fast construction speed.

As a permanent membrane, Dankai PTFE building membrane is mainly divided into outer membrane and inner membrane, and its performance is quite different. PTFE building membrane material for outer membrane General
Mainly used as roof materials, canopy materials and exterior decoration. As a roof material is generally used in stadiums, exhibition halls, airport halls, shopping centers, entertainment centers and other large
Public facilities. If the Millennium Dome on the Thames River is applied, the membrane material covers an area of more than 180000 m2, which is the largest area of a single membrane organization. Jeddah Airport in Saudi Arabia has a large waiting area.
The hanging membrane mechanism of the hall covers an area of 420000 m2. The 80,000-person Gymnasium in Shanghai, covering an area of 3.6 m2, is the first time that membrane institutions have been applied to large-scale buildings in China, with deep influence.
Far.
PTFE as a canopy material is generally used in the square, park green space sketch, amusement park, station and other facilities. As an exterior decoration is mainly the use of film material art and can be
Shaping, such as the Shanghai World Expo Pavilion Expo Axis. The inner membrane is mainly used as a sound absorption and insulation material, and its mechanical properties are lower than the outer membrane. Most
The typical project is the Bird's Nest, the main stadium of the National Stadium Olympic Games, which adopts PTFE ETFE structure, and the upper layer is ETFE membrane structure to prevent wind and snow. The lower layer is 53000m2
The PTFE membrane structure mainly plays the role of sound absorption ceiling. The sound absorption through the PTFE membrane structure can ensure the clear sound in the stadium.
