We all know that both traditional filter paper and advanced Teflon liquid filtration membranes have porous structures, but people generally choose the latter. Why is this? The reason is simple, because the latter has a better filtration effect of excellence.
Teflon liquid filtration membrane, also known as polytetrafluoroethylene membrane, is a perfluorinated polymer obtained by polymerizing the monomer tetrafluoroethylene and can be used for a long time in the range of -200~250℃.
In its molecular structure, the carbon atom is surrounded by 4 fluorine atoms. Since the covalent radius of the fluorine atom (0.064nm) is larger than the radius of the hydrogen atom (0.028nm), the fluorine atoms can be arranged to surround the carbon chain. Live, and because fluorine atoms repel each other, the entire macromolecular chain does not have a zigzag shape like a hydrocarbon molecular chain, but a helical structure similar to the human DNA helix.
Outside of the carbon chain skeleton of Teflon, which is susceptible to chemical attack, a tight and completely “fluorinated” protective layer is formed, which protects the PTFE main chain from attack by any external reagents, making the Teflon microporous membrane unique Solvent resistance, chemical stability, and low cohesive energy density unmatched by other materials.
It is a manufacturer specializing in the production of polytetrafluoroethylene membrane materials. The Teflon liquid filter membrane produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. , for some very small particles with a diameter of 0.1um-0.3um, the filtration level can reach H13-U16.
In the field of industrial sewage treatment, we have the characteristics of “uniform and stable, high efficiency and low resistance, long life, customizable, easy cleaning and maintenance”, etc., and are accepted and loved by the majority of enterprises.
