What Are The Characteristics Of PVC Membrane?
PVC membrane material is a special structural system different from traditional structures. The membrane material is not only a structural bearing member, but also a roof envelope material. At the same time, the membrane material itself is a very good decorative material. Therefore, compared with the traditional structure, the membrane structure Has the following advantages:
1. Department of Art. Membrane structure is based on modeling and color science. It can combine natural conditions and ethnic customs to create curves and shapes that are difficult to achieve in traditional buildings according to the architect's creativity. The changeable supporting structure and flexible membrane material make the building more diverse, novel and beautiful, and at the same time reflect the beauty of the structure, and the colors are rich, which can create a freer architectural form and express a richer architectural language.
2. Economical. The weight of membrane building roof is only 1/30 of that of conventional steel roof, which reduces the cost of wall and foundation. At the same time, the peculiar shape and night scene effect of the membrane building have obvious "architectural visibility" and commercial effect, and its price-effectiveness ratio is higher.
3. Energy saving. The film has high reflectivity and low light absorption, and has low thermal conductivity, which greatly prevents solar energy from entering the room. In addition, since the film itself has good light transmittance (10%~20%), the translucency of the film ensures proper natural slow scattered light to illuminate the room. Building spaces can get natural diffused sunlight during the day, which can save a lot of energy used for lighting.
4. Self-cleaning. The protective coating on the membrane surface, such as PVDF (polyvinylidene fluoride), has the characteristics of high temperature resistance and is not sticky, so that the dust falling on the membrane surface can be washed by rainwater to achieve self-cleaning effect.
5. Large-span unobstructed visual space. The weight of the membrane material used in the membrane structure is only 1/30 of that of the traditional building material. Due to its light weight, the membrane building can cover the space with a large span without the need for an internal support surface, which enables people to design and use it more flexibly and creatively. construction space. Moreover, since the cable-membrane structure provides stiffness through prestressing, the high tensile strength of the membrane material and the application of high-strength cables should realize a free and flexible large-span space structure. Therefore, it is especially suitable for sports venues, public facilities coverage, etc. Applications.
6. Shorter construction period. All processing and fabrication in the membrane structure project can be completed in the factory according to the design, and only the installation work is carried out on site. Compared with the construction period of traditional buildings, it has unparalleled advantages.
