I-PTFE inokushisa okuhle kakhulu okuphakeme nokuphansi kokusebenza, ukuzinza kwamakhemikhali, ukwahlukanisa kahle kukagesi, ukunganamatheli, ukumelana nesimo sezulu, ukungashi kanye nokuthambisa okuhle.Isetshenziswe emikhakheni ye-aerospace ezinhlobonhlobo zezimpahla zansuku zonke, futhi isiphenduke into ebaluleke kakhulu ukuxazulula ubuchwepheshe obuningi obubalulekile kusayensi yesimanje nobuchwepheshe, imboni yezempi kanye nokusetshenziswa komphakathi.
Ukusetshenziswa kokunqanda ukugqwala nokwehliswa kokugqokwa Ngokwezibalo ezifanele zamazwe athuthukile, ukulahlekelwa komnotho okubangelwa ukugqwala kubala cishe u-4% yenani eliphelele lomkhiqizo wezomnotho kazwelonke minyaka yonke emazweni anamuhla anezimboni.Inani elikhulu lezingozi ekukhiqizweni kwamakhemikhali libangelwa ukubola kwamakhemikhali okubangelwa ukugqwala kwemishini nokuvuza okuphakathi.Kuyabonakala ukuthi ukulahlekelwa kanye nokulimala okubangelwa ukugqwala kubi kakhulu, okuye kwavusa ukunaka okukhulu kwabantu.
I-PTFE inqoba ububi bepulasitiki evamile, izinsimbi, igraphite nezitsha zobumba, njengokumelana nokugqwala okubi kanye nokuguquguquka.Ngokumelana kwayo okuhle kakhulu nokushisa okuphakeme nokuphansi nokumelana nokugqwala, i-PTFE ingasetshenziswa ezimeni ezinzima ezifana nezinga lokushisa, ingcindezi kanye nendawo ephakathi, futhi isibe yimpahla eyinhloko emelana nokugqwala ku-petroleum, amakhemikhali, izindwangu nezinye izimboni.Ipayipi le-PTFE lisetshenziswa kakhulu njengepayipi elidlulisayo kanye nepayipi lokukhipha igesi elonakalisayo, uketshezi, umusi noma amakhemikhali.Ipayipi eliphusha elenziwe nge-PTFE dispersion resin likleliswe epayipini lensimbi ukuze lenze ulwelwesi, noma ipayipi langaphakathi le-PTFE liqiniswa yi-fiber yengilazi evunguzayo, noma ipayipi le-PTFE eliphushayo liqiniswa ukwelukwa nocingo lwensimbi olusongayo, olungadlulisa uketshezi. medium ngaphansi kwengcindezi ephezulu.Njengengxenye ebalulekile yokudluliselwa kwe-hydraulic, ingathuthukisa kakhulu amandla okuphuka ekushiseni okuphezulu futhi ibe nokukhathala okuhle kokugoba.Ngenxa yokuthi i-coefficient yokungqubuzana kwezinto ze-PTFE iphansi kakhulu phakathi kwezinto eziqinile ezaziwayo, yenza okokusebenza okugcwele kwe-PTFE kube okubalulekile kokugcotshwa kwamafutha angenawo uwoyela wezingxenye zemishini kawoyela.Isibonelo, imishini emikhakheni yezimboni zokwenza iphepha, izindwangu, ukudla, njll. ingcoliswa kalula ngamafutha okugcoba, ngakho ukugcwalisa izinto ze-PTFE kuxazulula le nkinga.Ngaphezu kwalokho, ucwaningo lufakazela ukuthi ukwengeza inani elithile lezithasiselo eziqinile kuwoyela wenjini kungasindisa ngempumelelo cishe u-5% wamafutha enjini.
Okunye ukusetshenziswa okukhulu kwempahla yokuvala engagqwali ye-PTFE embonini yamakhemikhali into yokuvala.Ngenxa yokusebenza kwayo okuhle okuphelele, i-PTFE ayinakuqhathaniswa nanoma yiluphi uhlobo lwempahla yokuvala.Ingasetshenziselwa ukuvala ezikhathini ezinzima ezihlukahlukene, ikakhulukazi lapho izinga lokushisa eliphezulu nokumelana nokugqwala kuyadingeka.
I-Teflon tape ine-fiber ende, amandla aphezulu, ipulasitiki ephezulu kanye ne-calendability enhle, futhi ingavalwa ngokuphelele ngokusebenzisa amandla amancane okucindezela.Kulula ukuyisebenzisa nokuyifaka, futhi isebenza kahle kakhulu uma isetshenziswa endaweni engalingani noma enembayo.Inokusebenza okuhle kokuvala, ingathuthukisa ukumelana nokugqwala futhi yandise uhla lwayo lokusebenza.Ukupakisha kwe-PTFE kusetshenziselwa ukuvala izingxenye ezishelelayo, ezingathola ukumelana nokugqwala okuhle nokuzinza, futhi kunokucindezelwa okuthile nokuqina, nokumelana nokuncane lapho ushelela.Impahla yokuvala ye-PTFE egcwele inezinhlobonhlobo zokushisa ezisetshenziswayo, okuyiyona ethatha indawo eyinhloko yezinto ezivamile ze-asbestos gasket njengamanje.Ibuye ibe nezindawo ze-modulus ephezulu, amandla aphezulu, ukumelana nokukhasa, ukumelana nokukhathala, ukuhanjiswa okuphezulu kwe-thermal, i-coefficient ephansi yokwandisa okushisayo nokungqubuzana, njll. Ukwengeza ama-fillers ahlukene kunganweba ububanzi besicelo.
