I-PTFEkanye ne-TFM isetshenziselwa ukuvuthela ezicelweni zokumelana nokugqwala okwedlulele - ikakhulukazi ama-organic compounds, ama-acids, nosawoti - kanye nezinga lokushisa eliphezulu kanye nezicelo zokuhlanzeka okuphezulu.Zombili zibonisa ukuziphatha okunganamatheli, futhi zinebanga elifanayo elibanzi lokushisa lokusebenzisa.Kodwa-ke, kunomehluko omkhulu phakathi kwazo, okungukuthi ngenxa yokuthi i-TFM ihlanganisa izici ezinhle kakhulu zakho zombili i-PTFE ne-PFA.I-TFM iyisivunguvungu esiyikhethela uma udinga ukungena kwegesi okuphansi kakhulu, impilo ende yokukhathala, kanye nokuqedwa kwendawo okushelelayo.
I-PTFE eguquliwe inguqulo ye-PTFE eguqulelwe ngamakhemikhali enamandla amasha ngaphezu kwezici zesakhiwo ezihambisana nezinto ezimsulwa ze-PTFE.
I-PTFE eguquliwe inalezi zici ezintsha noma ezithuthukisiwe kune-PTFE ejwayelekile:
Izingxenye ezingaphezulu zibushelelezi, futhi azinambobo encane - izingxenye zihlala zihlanzekile ngoba mancane amathuba okuba zibambe ukungcola Okuqukethwe okungenalutho okuncane okuncane kukhiqiza umkhiqizo othuthukisiwe wokumelana ne-permeationImpilo eguquguqukayo emide kune-PTFEUkwenyuka kokuqina & ukumelana nokukhasa okuthuthukisiwe Amandla e-dielectric aphezulu akhiqiza ukufakwa kwamandla kagesi aphezuluFusible / Weldable (Utilizing izindlela ezihlukahlukene zokushisela ukushisa ezinengcindezi emaphakathi)Izibonelo Zeziqukathi namashubhu adalwe kusetshenziswa i-APT's Modified PTFE Fusing & Machining Processes
I-PTFE imele i-Polytetrafluoroethylene, i-fluorocarbon thermoplastic ethole ukusetshenziswa okubanzi ezinhlelweni zobunjiniyela futhi yaziwa kakhulu ngokuba ne-coefficient ephansi yokungqubuzana kwanoma yikuphi okuqinile.Yaziwa nangokuthi i-polymer, i-Dyneon TM, i-1,1,2,2-tetraflouroethene noma i-1,1,2,2-tetraflouroethylene.
Njengoba sekushiwo, i-PTFE ingenye yama-polymers angasebenzi ngamakhemikhali atholakalayo (Ishadi Lokumelana Nemakhemikhali).Inebanga lokushisa eliqhubekayo lokusebenzisa ukusuka ku -200°C kuya ku-250°C futhi alikwazi ukumelana nokumuncwa kwamanzi.Ngaphezu kwalokho, inokuziphatha okungahambisani nokunamathelayo okumelana nokwakheka kwezinto eziqinile, okwenza kube lula ngendlela emangalisayo ku-CIP (Clean In Place).Eqinisweni, kukhona amamaki ahlukahlukene e-PTFE agunyazwe yi-FDA.
I-PTFE eshintshiwengokwekhemikhali ibizwa nge-polytetrafluoroethylene, futhi ngegama lokuhweba i-Polyflon.Kuyinhlanganisela ethokozisayo yezakhiwo ze-PTFE kanye ne-PFA (Perfluoroalkoxy), eyaziwa ngezici zayo eziphakeme zokuwenza.
Njenge-PTFE, i-TFM ayisebenzi ngamakhemikhali futhi inobubanzi obufanayo bokushisa kokusetshenziswa okuqhubekayo, kanye nokumelana okufanayo nokumuncwa kwamanzi.Iphinde igcine izici eziningi ezinganamatheli ze-PTFE.
I-TFM futhi inezinga lentwasahlobo eliphakeme kancane, kodwa izici zokukhathala ezingcono ngokuphawulekayo futhi ibonisa ukululama okungcono kwengcindezi.Ngaphezu kwalokho, kulula ukushisela kune-PTFE futhi inesisindo esincane.I-TFM iphinde imelane nakho kokubili ukuthuthukiswa nokuguga.
Into eyodwa eyenza i-TFM ikhetheke ukuminyana kwesakhiwo samangqamuzana.Lokhu kubangela izinga eliphansi kakhulu lokungena kwegesi kogqinsi olufanayo lwento uma kuqhathaniswa ne-PTFE.Lesi sici sibaluleke kakhulu uma sisetshenziswa endaweni eyonakele kakhulu.Ngesakhiwo sayo samangqamuzana aminyene, i-TFM iphinde inikeze isiphetho esibushelelezi saleyo PTFE.Futhi, njenge-PTFE, kunamabanga ahlukahlukene e-TFM agunyazwe yi-FDA.
