More common PVDF and PTFE membrane material, but PVDF relative to PTFE, whether performance or service life are worse
More common PVDF and PTFE membrane material, but PVDF relative to PTFE, whether performance or service life are worse, but PVDF membrane material than PTFE membrane material used more in the north, why in the northern membrane structure PVDF membrane material than PTFE membrane material is more popular? The following with the small edition of Zhanji membrane structure company to take a look.
1. The inner wire of PTFE film is glass fiber, so the processing difficulty is greater than that of PVDF film.
2, from the use of cost performance, PVDF film material than PTFE film material in price is several times cheaper.
3, because PTFE membrane material has a small bending radius, is not suitable for folding transport, and PVDF membrane material can be folded transport.
4, because the PTFE membrane material is brittle, in order to prevent the glass fiber from being broken in the construction, it is necessary to have special treatment and construction skills. And PTFE film material in the middle of the hoisting construction and installation process will break off, white imprint, affect the beauty and strength.
5, PVDF film material flexibility is high, the northern climate is cold, the temperature is falling, PTFE film material is more easy to fracture. PVDF membrane material in the temperature drops, still has a high softness. More suitable for northern use.
6, at the turn of winter and spring, the membrane structure in the north will occur freeze-thaw phenomenon, PVDF membrane material inside the wire for polyester filament, so it is more suitable for use in the north. However, some cracks have occurred in the PTFE film during the installation process, and there is a greater risk of damage in freezing and thawing.
With the development of society and the improvement of people's living standards, the gymnasium has become an important place for people to carry out sports activities and entertainment.
In environmental engineering, capping is one of the common and effective methods for sewage deodorization. Moreover, by covering the sewage treatment tank, the surrounding environment is effectively protected, achieving the purpose of purifying the foul gas in the sewage treatment tank. It can effectively prevent the diffusion and release of foul gas, thereby reducing its impact on the surrounding environment and human health.
Gas film building is a semi permanent building, but its actual service life is more than 20-30 years. How many years can gas film be used in heavily polluted areas of the coal industry?
The composition of the waste gas in the sewage tank is complex, which is very harmful to the environment and human body.
