PTFE membrane yog ib daim nyias nyias, cov yeeb yaj kiab uas muaj qhov ntxeem tau zoo uas ua tau raws li cov ntaub ntawv tsis txaus ntseeg.Lawv qhov xwm txheej hydrophobic ua rau PTFE daim nyias nyias zoo rau cov ntawv thov xws li lim roj, aqueous aerosols, tiv thaiv lub tshuab nqus tsev twj, lossis lub tshuab ua kom tsis muaj menyuam fermentation tso tsheb hlau luam.PTFE yog inert rau feem ntau chemically aggressive solvents, muaj zog acids thiab bases thiab yuav siv tau rau hnyav clarification thiab HPLC qauv prep.
PTFE daim nyias nyias muaj qhov tsis muaj kev txhawb nqa thiab txhawb nqa.PTFE daim nyias nyias nrog lub laminated polypropylene web txhawb nqa rau ib sab muaj kev txhim kho tuav cov yam ntxwv.Kev txwv tshuaj lom neeg thiab thermal yog tsim los ntawm kev txhawb nqa.
Ib qho ntawm cov yam ntxwv tseem ceeb hauv kev xaiv daim nyias nyias yog seb koj xav tau daim nyias nyias uas yog Hydrophobic lossis Hydrophilic.Ntawm no peb yuav txhais cov ntsiab lus no, nrog rau muab qee qhov piv txwv ntawm cov ntaub ntawv membrane thiab daim ntawv thov rau ob hom.Hydrophilic txhais tau tias "hlub dej."Hydrophilic membranes yuav nyiam dej, thiab hauv cov txheej txheem thawb tawm lwm cov molecules thiaj li tso dej nkag mus rau hauv daim nyias nyias.Qhov no ua kom cov kab mob nyob deb ntawm daim nyias nyias kom nws huv si thiab ua haujlwm rau lub sijhawm ntev dua.Vim tias qhov zoo li no hydrophilic membranes yog qhov tshwj xeeb zoo rau kev siv tshuaj kho mob thiab tshuaj lom neeg.Hydrophobic ntawm qhov tod tes, txhais tau tias "ntshai dej."
Cov membranes no yuav thaiv txoj kev hla dej thiab feem ntau yog siv rau cov ntawv thov kev sib cais ntawm cov dej los ntawm lwm cov ntaub ntawv, xws li cov pa roj.Ntawm no yog ib lub rooj pab uas sib piv cov ntaub ntawv membrane thiab kev siv rau hydrophilic thiab hydrophobic zog:
