I-PTFE ulwelwesi ifilimu elizacile, elinezimbotshana eziningi ezisebenza njengolwelwesi olubambekayo ngokuphelele.Imvelo yabo ngokwemvelo ye-hydrophobic yenza ulwelwesi lwe-PTFE lulungele ukusetshenziswa okufana namagesi okuhlunga, ama-aerosols anamanzi, amaphampu evacuum avikelayo, noma amathangi okuvuthela angenalutho.I-PTFE ayisebenzi kuzincibilikisi eziningi ezinolaka lwamakhemikhali, ama-asidi aqinile nezisekelo futhi ingasetshenziselwa ukucaciswa kwencibilikizo kanye nokulungiselelwa kwesampula kwe-HPLC.
Ama-membrane e-PTFE ayatholakala angasekelwe futhi ayasekelwa.Ama-membrane e-PTFE anosekelo lwewebhu lwe-laminated polypropylene ohlangothini olulodwa lunikeza izici zokuphatha ezithuthukisiwe.Imikhawulo yamakhemikhali neyokushisa ibekwa ngokusekelwa.
Esinye sezici ezibalulekile ekukhetheni ulwelwesi ukuthi ufuna ulwelwesi oluyi-Hydrophobic noma i-Hydrophilic.Lapha sizochaza la magama, futhi sinikeze izibonelo zezinto zolwelwesi kanye nokusetshenziswa kwazo zombili izinhlobo.I-Hydrophilic ngokwezwi nezwi isho “ukuthanda amanzi.”Ulwelwesi lwama-hydrophilic luzoheha amanzi, futhi kule nqubo lusunduze amanye ama-molecule ukuze avumele ukufinyelela kwamanzi kulwelwesi.Lokhu kugcina ukungcola kude nolwelwesi oluvumela ukuthi luhlale luhlanzekile futhi lusebenza isikhathi eside.Ngenxa yalesi sici ulwelwesi lwe-hydrophilic lufaneleka kakhulu ukusetshenziswa kwezokwelapha kanye nokuhlolwa kwezinto eziphilayo.Ngakolunye uhlangothi, i-Hydrophobic, ngokwezwi nezwi isho “ukwesaba amanzi.”
Lezi zingqimba zizovimba ukudlula kwamanzi futhi zivame ukusetshenziselwa izinhlelo zokusebenza ezibandakanya ukuhlukaniswa kwamanzi kwezinye izinto, njengamagesi okukhipha umoya.Nali ithebula eliwusizo eliqhathanisa izinto zolwelwesi kanye nokusetshenziswa okuvamile kwezakhiwo ze-hydrophilic ne-hydrophobic:
