Iimveliso ze-PTFE

I-PTFE isetyenziswa njengegama lokurhweba kwezinye iipholima ezimbalwa ezinokwakheka okufanayo, njenge-ethylene propylene (FEP) kunye ne-perfluoroalkoxy resin (PFA) Iimpawu zezi polima ziyafana nezo ze-ptfe.

I-FEPFEP ithambile kunepolima kwaye icace kakhulu kwaye imelana nokukhanya kwelanga.Yenziwe ngakumbi kunepolymer.Inomlinganiso ophantsi kakhulu wokukhuhlane kunye nokumelana okuphezulu nobushushu.Ingasetyenziselwa ukuwelda, ukutywinwa kobushushu, kunye ne-thermoforming.Isetyenziselwa ukuyila kunye nokuveliswa kwe-thermoplastics eneempawu eziphantsi zokukhuhlana.I-FEP yokugquma i-nonstick isetyenziswa kakhulu ekugqumeni izikhongozeli ezisetyenziselwa ukubhaka kwimizi-mveliso.I-FEP ikhona kuzo zombini iimo zolwelo ezisekwe emanzini kunye nomgubo.

ukujonga iimpawu zeFEP.

I-PFAPFA ayisebenzi ngokwendalo kwaye inomlinganiso ophantsi wokukhuhlana.I-PFA ikwasetyenziselwa ukugquma iimpahla zokubhaka kwimizi-mveliso.Nangona kunjalo, iimpawu zokusebenza ze-PFA zingcono kakhulu kunezo ze-FEP kuba i-PFA inokumelana namaqondo obushushu aphezulu ixesha elide.Ukongeza, inokuqina okukhulu kune-FEP kunye ne-polymer.I-PFA ikhona kwifomu yomgubo kunye nolwelo.

ukujonga iipropati zePFA.

I-Tefzel okanye i-ETFEETFE yi-copolymer ye-ethylene kunye ne-tetrafluoroethylene.Igama layo lentengiso yiTefzel.Isakhiwo se-molecular ye-ETFE sihluke kancinane kwi-polymer.Kwi-polymer, zonke iiathom ze-hydrogen zitshintshwa yi-fluorine ngelixa kwi-ETFE, inani elincinci lee-athomu ze-hydrogen zitshintshwa.
