Characteristics of membrane structure:



Fire performance



Nowadays, the widely used membrane materials can well meet the requirements of fire prevention technology, with excellent flame retardant and high temperature resistance, reaching the standards of France, Germany, the United States, Japan and other countries.



mechanical property



Medium strength PVC film: its thickness is only 0.*1mm, but its tensile strength is half that of steel. Medium strength PTFE film: its thickness is only 0.8mm, ETFE film: its thickness is **0um, but its tensile strength has reached the level of steel. The elastic modulus of the membrane material is low, which is conducive to the formation of complex surface modeling. Environmental performance: according to the research report, the sunlight reflectivity of black roofs is usually *0% - *0%. If the roof is covered with high reflectivity white materials, the reflectivity can be increased to more than *0%. According to the report, a white roof can save *0% of a building's energy. If a building with a roof area of about *0 square meters uses a white roof, the environmental protection effect is equivalent to reducing *0 tons of carbon dioxide emissions every year.



Thermal insulation performance



The insulation performance of single-layer membrane material is the same as that of brick wall, better than that of glass. Like other materials, the interior temperature of membrane building can be adjusted in other ways. For example: internal hanging insulation layer, the use of air conditioning heating equipment.



optical performance



The membrane material can filter out most of the ultraviolet rays and prevent the internal items from fading. Its transmissivity to natural light is up to *5%. The transmitted light produces uniform diffuse light inside the structure, without shadow and glare. It has good color rendering. At night, under the combined action of ambient light and internal lighting, the surface of the membrane structure emits natural and soft light, which is intoxicating.



Acoustic performance



Generally, the membrane structure is almost transparent for the low frequency below *0Hz. The membrane structure with fabrasorb device can be used for the structure with special sound absorption requirements. This combination has stronger sound absorption effect than glass.



Self cleaning performance



ETFE, PTFE membrane and PVC membrane with special surface treatment have good self-cleaning performance. Rainwater will gather on the surface of ETFE, PTFE membrane and PVC membrane and flow down, so that the membrane surface can be naturally cleaned.
