It takes time to find the right membrane in the dazzling world of membranes. In fact, if you know the characteristics of the membrane, we can easily make a choice. Today we first look at the characteristics of the membrane.
In the world of membrane structure buildings, the most commonly used membrane materials are mainly PTFE architectural membranes and PVDF architectural membranes. PTFE architectural membrane material refers to a composite material composed of a PTFE (polytetrafluoroethylene) resin coated on a base fabric formed of extremely fine glass fiber (3μm). The PTFE architectural membrane material is a dry-flow membrane structure construction material in the world today. PVDF architectural membrane material refers to a composite material composed of a polyester fiber woven base fabric coated with a PVC bottom layer, and then coated with a PVDF (polyfluoroethylene) resin on the PVC bottom layer. This type of membrane material has an existing membrane structure in China. Widely used in architecture.
What features does the membrane have? First, excellent optical function, second, superior acoustic function, third, excellent fire protection function, fourth, excellent thermal insulation function, fifth, unique self-cleaning function.
Let's analyze it specifically:
The membrane filters out most of the UV rays and prevents discoloration of indoor items. Its transmissivity to natural light can reach 25%, and the light passing through the film is natural slack light, no shadows and glare will occur, which guarantees its excellent color rendering. It is illuminated at night and outside at night Under the irradiation of light, the film structure constitutes a crystal clear translucent body, which has a strong visual impact.
2. The general structure has superior acoustic functions, which is almost transparent to low frequencies below 60Hz. For structures with special sound absorption requirements, the membrane structure with FABRASRB equipment can be selected. This combination has a stronger sound absorption effect than glass .
3. The architectural membrane widely used in modern society has reached or surpassed the fire protection standards of France, Germany, the United States, Japan, and China, and can meet the fire protection requirements. It has excellent flame retardancy and high temperature resistance. function.
4. The thermal insulation function of single-layer film is equivalent to brick wall, which is better than glass. Like other buildings, the membrane structure can also use a variety of methods to regulate the internal temperature.
5. PTFE membrane and PVC membrane with special surface treatment have excellent self-cleaning function. Surface dust and rainwater will condense into water droplets and flow down to make the membrane surface naturally clean.
