Duoxiang data research shows that membrane filtration is superior to other separation processes, such as distillation or crystallization, in terms of energy consumption, ease of operation and filtration effect.
Therefore, excellent membrane filtration materials are very important. Today I will introduce Teflon liquid filtration membrane.
The transmembrane pressure difference required for membrane separation is generally 0.5~2.0MPa, which is 0.5~3MPa lower than the pressure difference necessary to achieve the same permeability energy with Teflon liquid filtration membrane.
Based on the operating pressure and separation limit, NF can be qualitatively ranked between reverse osmosis and ultrafiltration. NF is sometimes called low-pressure reverse osmosis or loose reverse osmosis.
J.E. Cadotte studied NS-300 membrane in the 1970s, which was the beginning of research on NF membrane.
At that time, the Israeli Desalination Company used “hybrid filtration” to refer to the membrane separation process between reverse osmosis and ultrafiltration. Later, American companies called this membrane technology nanofiltration, which is still used today.
After that, NF developed rapidly, and membrane modules were commercialized in the mid-1980s.
Currently, NF has become one of the hot spots in membrane separation research in the world.
It is a Teflon liquid filtration membrane manufacturer specializing in R&D, production and sales.
Our company is different from other manufacturers.
Our company can customize according to user’s requirements.
The optimized combination of key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different requirements you need. .
The products we produce are all produced from imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
