The pressure difference required for ptfe liquid filtration membrane to achieve the same penetration energy is 0.5~3MPa lower.
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.
The surface of the ptfe liquid filtration membrane is composed of 100~200 nanofibers staggered into holes. After the fiber diameter is reduced to the nanometer level, the surface area increases, the pore size becomes smaller, and the pore volume increases, which can effectively block PM2.5.
It also has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is laminated on various fabrics and substrates using a special process. material, it can become a new type of filter material.
