PTFE membrane material features: 1. High strength, good durability, fire-resistant, flame-retardant, self-cleaning and not affected by ultraviolet light, its service life is more than 20 years. 2. With high light transmission, and light through the film material is a natural diffuse light, no shadow, no glare. 3. The reflectance of solar energy is high, so there is little heat absorption.
The Chinese name of ETFE is ethylene-tetrafluoroethylene copolymer
Ethylene-tetrafluoroethylene copolymer, scratch resistance, wear resistance, high temperature resistance, corrosion resistance, high insulation material safety. Ultra light weight: Thin and light film. Excellent earthquake resistance and convenient construction. Durability is good: climate adapts: -200~150 degrees Celsius, bad weather for more than 15 years.
Characteristics of the PVC film material: The strength and fire resistance of the PVC film material have a certain gap compared to PTFE. The service life of the PVC film material is generally 7 to 15 years. In order to solve the self-cleaning problem of PVC film materials, PVDF (polyvinylidene fluoride acetic resin) is generally coated on the PVC coating and is called a PVDF film material.
Membrane materials: Membrane materials refer to polyester textile fabrics or PVDF, PVF, PTFE and other surface coatings, together with high-quality PVC composed of a stable shape, and can withstand a certain load of construction textiles. Its life span varies with different surface coatings and can generally be achieved for 12-50 years.
Membrane structure advantages
1. Freedom of building shape
Varied support structure and flexible membrane material make the building model more diversified, novel and beautiful, and at the same time reflect the beauty of the structure and color
Richness can create more free building shapes and richer architectural language.
2. Better economic benefits
Membrane building roof weight is only 1/30 of the conventional steel roof, which reduces the cost of the wall and the foundation. At the same time, membrane construction is unique
The type and night effects have obvious "architectural recognizability" and commercial effects, and their price-benefit ratio is higher.
3. Shorter construction period
All the processing and production in the membrane engineering can be done in the factory according to the design, and only the installation work is performed at the site. Compared to traditional architecture
It is almost twice as fast as the construction period.
4. Lower energy consumption
The film material has higher reflectivity and lower light absorption, and lower thermal conductivity, which largely prevents solar energy from entering the room
Inside. In addition, the translucency of the film ensures a proper natural diffusely diffuse light illumination chamber.
5. Greater span of architectural space
Due to its light weight, membrane construction can eliminate the need for large spans of internal supporting surfaces to cover the space, which allows people to be flexible and creative.
Design and use of architectural space.
