Brief introduction of PTFE architectural membrane material

Product Overview:

The PTFE membrane structure is a new form of architectural structure that incorporates architecture, structural mechanics, fine chemicals and materials science. Computer technology is one, with high technical content. The surface can be arbitrarily changed according to the architect's design needs, and combined with the overall environment, building an iconic image project. Under the sunlight, the interior of the building covered by the membrane is filled with natural diffuse light. Without the contrast between the highlight surface and the shadow, the indoor visual environment is open and harmonious. At night, the lights in the building illuminate the night sky through the membranes of the roof, and the building's shape shows a fantastic effect.

Features:

1. PTFE membrane material has advantages such as high strength, good durability, fireproof, flameproof, self-cleaning, not affected by ultraviolet rays and light weight (about 1/30 of the weight of the previous steel ceiling). It can be installed at the factory after cutting and welding at the factory, which can shorten the construction period.

2. The PTFE membrane material has high reflectivity and low absorption rate to sunlight, and it can rely on the minimum heat capacity to inhibit the penetration of the solar energy source into the structural building. At the same time, due to its translucent characteristics, daylight is less than the use of artificial lighting, which can actually save energy costs.

3, PTFE membrane structure Buildings generally do not need internal support to cover a vast space with a thin film, and can be freely designed and utilized in a variety of spaces.

4. The transmittance of PTFE membrane is about 13%, and it can convert sunlight into moisture with less shadow, and can get the original color of the same object as outdoor.

5, PTFE has a high degree of self-cleaning PVDF can not be compared, fluorine resin has non-adhesive, waterproof and other functions, the appearance of the accumulation of dust, atmospheric dirt, etc. washed in the rain washed clean, clean and white for a long time.

Product performance:

1, with high mechanical properties

With a thickness of only 0.80mm PTFE film, its tensile strength has reached the level of steel. The modulus of elasticity of the membrane is much lower than that of other building materials, which is conducive to the formation of complex curved surfaces of the membrane. PTFE architectural membranes have excellent optical properties.

Most of the UV rays can be filtered to prevent the fading of indoor objects. Its natural light transmission rate can reach 25%, and the light that passes through the film material is natural scattered light, no shadows are generated, no glare occurs, and good color rendering is ensured, and internal lighting and external light are used at night Under the common irradiation, the film structure forms a translucent translucent body with strong visual impact.

2, has excellent acoustic properties

The general membrane structure has superior acoustic properties, and is almost transparent to low frequencies below 60 Hz. For structures with special sound absorption requirements, membrane structures with FABRASRB devices can be used. This combination has a stronger sound absorption effect than glass.

3, with excellent fire performance

The architectural membrane material widely used in modern society has reached or surpassed the fire protection standards of many countries such as France, Germany, the United States, Japan, and China, and can well meet the fire protection requirements, and has excellent flame retardant and high temperature resistance.

4, has a good thermal performance

Single-layer membranes have the same insulating properties as brick walls and are superior to glass. As with buildings of other materials, the inner temperature of the membrane-structured building can also be adjusted in various ways.

5, has a unique self-cleaning performance

With the high self-cleaning properties unmatched by PVDF, the fluororesin has non-adhesive and water-repellent properties, and dust, atmospheric dirt, etc. accumulated on the outside are washed away after being washed by rain and kept clean and white for a long time.

Applications:

Architectural membrane materials are widely used in large-scale public facilities: roof systems of stadiums, airport halls, exhibition centers, platforms, and landscape pavilions.
