Why are ETFE membrane structures so popular?
What are the advantages and disadvantages of ETFE membrane structure membrane material?
ETFE membrane structure membrane material is a new type of membrane material, usually in the form of air pillow used in buildings.
The most typical example in China is water cube. The shewater cubef BBB1 is composed of 3,065 ETFE air pillows, covering an area of 100,000 square meters, and the expansion area of membrane material reaches 260,000 square meters. It is the largest ETFE membrane structure building in the world.
Now the use of ETFE membrane building also began to be more and more, so what are the advantages and disadvantages of ETFE membrane structure membrane material?

Advantages of ETFE membrane structure membrane material
1, light weight and good physical properties
ETFE film material is automatically very light (only 0.15-0.35 kg per square meter), but as mentioned above it has good physical properties, insulation, wear resistance, abrasion resistance, corrosion resistance, tensile strength is greater than 40Mpa, breaking elongation is more than 300%.
2, long service life
ETFE membrane material has excellent anti-aging ability, service life can reach more than 25 years.
3, good light transmittance
ETFE membrane material is usually colorless and transparent, and can also be made white.
Various patterns can be printed on transparent or white membrane materials according to requirements.
Taking 0.20mm thick ETFE membrane material as an example, the light transmittance of monolayer transparent membrane material is up to 95%, white ETFE membrane is 50%~55%.
The light entering the building can be adjusted by using white film or printing different colours and patterns on transparent film.
4, good fire performance
ETFE is flame retardant material (fire rating reaches B1), even in open fire, ETFE film material will shrink when heated, but no dripping, because its weight is very light, even if the fire, the risk is smaller.
5, self-cleaning performance is good
ETFE membrane structure membrane material surface is very smooth dust is not easy to adhere to, has a good self-cleaning performance, surface dust, dirt rely on rain natural scour can be removed, cleaning cycle greatly increased for 5 years.
6. Good climate adaptability
ETFE membrane structure membrane material can maintain stable performance in the temperature range of -200~150℃, the melting point of the material is about 275℃, so ETFE membrane material has excellent climate adaptability, according to the research data show that ETFE membrane exposed to harsh climate conditions for more than 15 years, its mechanical and optical properties did not change.
7, can be recycled recycling
The waste ETFE film material can be hot melted into granules and regenerated, which is a green and environmentally friendly material that can be recycled.
What are the disadvantages of such an excellent ETFE membrane structure membrane material?
Let's take a look
1. Toxic gases will be produced in fire
Although ETFE film material has a good fire performance, but in the fire it will produce toxic gases mainly carbon monoxide and fluorohydride, thanks to its combustion does not produce open flame drops, but the formation of a hole, which is beneficial to the discharge of smoke and gas.
2, poor sound insulation performance
Because ETFE membrane material is generally applied to the building in the form of air pillow, so when it encounters heavy rain or hail weather, it will produce a sound like beating a drum.
3. Small span of single air pillow
The span of ETFE air pillow cannot be too large. The economic span of a single air pillow is generally 3-5m. If the span is greater than 10m, it needs to be reinforced with multiple layers or steel cables.
4. High operating cost
The ETFE air pillow needs to be constantly inflated to maintain air pressure, and it relies on a set of automated inflating equipment, the operation and maintenance of which undoubtedly increases its operating costs.
5, power failure will affect the building function
As mentioned above, the ETFE air pillow needs to be constantly inflated to maintain air pressure. Power failure will cause the air pressure in the air pillow to drop, and the building performance will be affected accordingly.
6. High investment costs
The price of ETFE membrane material is higher than that of PVDF and PTFE. In addition, special inflatable equipment and electronic equipment are needed, so the investment cost of building ETFE membrane material is quite high.
The above is what are the advantages and disadvantages of ETFE membrane structure membrane material and why ETFE membrane structure building is so popular in detail, I hope to help you.
