The advantages of membrane structure materials

Now more and more places are using membrane structure architecture, membrane structure architecture appearance is fashionable, with a strong sense of art. Membrane material is a new kind of building material, which is recognized as the sixth kind of building material after wood, brick, stone, concrete and steel.

Membrane structure architecture is often used in sports venues, shopping malls, parking sheds, landscape structure and other places, popular with the public, membrane structure material has what advantages?

1. Durability

The base fabric of membrane structure material has light weight and high mechanical strength, and will not show obvious stress relaxation or creep during long-term stress.

Medium strength PVC film, its thickness is 0.61mm, but its tensile strength is equivalent to half of steel; The medium strength PTFE film, its thickness is only 0.5mm, but its tensile strength has reached the level of steel. (The thickness of PVC film used by Marriott is about 0.89mm, and the thickness of PTFE film is about 0.8mm)

PTFE coated glass fiber film life can reach 40 years,PVDF coated polyester fiber film life is 15 years.

2. Light transmission and heat transfer

The membrane material filters out most UV rays, preventing the fading of the contents. Its transmission rate of natural light can reach 20%, and the transmitted light produces uniform diffused light inside the structure, without shadow and glare, and has good color rendering. At night under the backlight irradiation, its appearance glow, can make the building become a symbol of the city landscape.

PTFE film has high light transmittance, light weight, high strength, fire resistance, good self-cleaning, not affected by ultraviolet light, fatigue resistance, distortion resistance, aging resistance, long service life. PTFE film has a long service life, also known as permanent building membrane. Because of its strong plasticity, exaggerated and beautiful shape, PTFE film is widely accepted and promoted by architects.

ETFE film has the same light transmission effect as glass, which is safer and lighter than glass, more plastic and creative. Air pillow form of heat preservation and energy saving effect is particularly significant. Long service life, self-cleaning due to good anti-adhesive surface properties. ETFE film can be divided into transparent matte, color, dot and so on several varieties; Because of its uniform material, the classification is generally divided according to its thickness, which can be divided into 150um, 200um, 250um, 300um and other levels;

Currently, 250um and 300μm are commonly used; The structure form can be single or multi-layer air pillow.

ETFE membrane material is widely used in the roofing system and facade decoration of all kinds of landmark buildings such as airports, high-speed railway stations, commercial squares and urban architectural landscapes, especially the combination of LED lighting effect will show all kinds of structural facilities infinite brilliance and bright.

3. Fire performance

Today's widely used membrane materials can well meet the needs of fire prevention, flame retardant and high temperature resistance, can reach France, Germany, the United States, Japan and other multinational standards.
