Nrog rau kev tshaj lij hauv kev sau npe, peb tsim cov ntawv zoo PTFE uas yog tsim los ntawm kev siv tshuab siab heev.
PTFE (polytetrafluoroethylene) yog lub siab molecular hnyav polymer thiab ib qho ntawm cov khoom siv ntau yam uas paub rau tib neeg.Daim ntawv no tuaj yeem ua tau zoo tag nrho cov tshuaj hauv 0-14 pH ntau yam tshwj tsis yog cov hlau alkali molten thiab cov tshuaj fluorine.Nws yog qhov tsim nyog rau kev pab cuam ntawm qhov kub thiab txias los ntawm cov khoom siv cryogenic mus txog 500 ° F.Daim ntawv no tau pom zoo tshwj xeeb rau cov ntawv thov hauv kev lag luam thiab cov txheej txheem kev lag luam uas tsis tas yuav muaj cov ntaub ntawv purity siab.Nws yog kev lag luam ntau dua li daim ntawv PTFE nkauj xwb thiab cov khoom siv lub cev tsuas yog me ntsis tsawg dua li cov nkauj xwb PTFE.
