I-PTFE inomsebenzi oncomekayo ophezulu kunye nomgangatho ophantsi wokushisa, ukuzinza kweekhemikhali, ukugquma kombane okulungileyo, ukunganamatheli, ukumelana nemozulu, ukuvutha kunye nokuthambisa okulungileyo.Isetyenziswe kwiindawo ze-aerospace kuluhlu olubanzi lwempahla yemihla ngemihla, kwaye iye yaba yinto eyimfuneko ekusombululeni itekhnoloji ephambili kwisayensi kunye nobuchwepheshe bale mihla, ishishini lomkhosi kunye nokusetyenziswa koluntu.
Ukusetyenziswa kwe-anti-corrosion kunye nokunciphisa ukunxitywa Ngokweenkcukacha-manani ezifanelekileyo zamazwe aphuhlileyo, ilahleko yezoqoqosho ebangelwa kukonakala ibalelwa malunga ne-4% yexabiso elipheleleyo lemveliso yesizwe yemveliso minyaka le kumazwe ashishinayo namhlanje.Inani elikhulu leengozi kwimveliso yeekhemikhali zibangelwa kukusabela kweekhemikhali okubangelwa kukubola kwezixhobo kunye nokuvuza okuphakathi.Kuyabonakala ukuba ilahleko kunye nokwenzakala okubangelwa kukuhlwa kubi kakhulu, nto leyo evuse ingqwalasela ebanzi yabantu.
I-PTFE yoyisa ukungalungi kweeplastiki eziqhelekileyo, isinyithi, igraphite kunye neeseramikhi, ezifana nokunganyangeki kokuhlwa kunye nokuguquguquka.Ngokuxhathisa ubushushu obuphezulu kunye nomgangatho ophantsi kunye nokuxhathisa ukubola, i-PTFE ingasetyenziswa kwiimeko ezinzima ezifana nobushushu, uxinzelelo kunye nomgangatho ophakathi, kwaye iye yaba yeyona nto inganyangekiyo kwi-petroleum, imichiza, i-textile kunye namanye amashishini.Umbhobho we-PTFE usetyenziswa ikakhulu njengombhobho wokuhambisa kunye nombhobho wokukhupha werhasi eyonakalisayo, ulwelo, umphunga okanye iikhemikhali.Umbhobho wokutyhala owenziwe nge-PTFE dispersion resin ufakwe kumbhobho wentsimbi ukwenza i-lining, okanye i-PTFE ityhala umbhobho wangaphakathi womelezwe yi-fiber yeglasi evuthuzayo, okanye i-PTFE umbhobho wokutyhala uqiniswa ngokuluka kunye nocingo lwentsimbi, olunokudlulisa ulwelo. eliphakathi phantsi koxinzelelo oluphezulu.Njengenxalenye eyimfuneko yokuhanjiswa kwehydraulic, inokuphucula kakhulu amandla okukrazuka kwiqondo lobushushu eliphezulu kwaye ibe nokudinwa okuhle kokugoba.Ngenxa yokuba i-friction coefficient ye-PTFE imathiriyeli iyeyona isezantsi phakathi kwemathiriyeli eqinileyo eyaziwayo, yenza imathiriyeli ye-PTFE ezaliswe yeyona nto ifanelekileyo yokuthambisa ioyile yamalungu esixhobo soomatshini.Ngokomzekelo, izixhobo kwiinkalo zoshishino zokwenza iphepha, i-textile, ukutya, njl.Ukongeza, uvavanyo lungqina ukuba ukongeza inani elithile lezongezo eziqinileyo kwi-oyile ye-injini kunokonga ngokufanelekileyo malunga ne-5% ye-oyile ye-injini.
Olunye usetyenziso oluphambili lwemathiriyeli yokutywina enganyangekiyo kwi-PTFE kushishino lweekhemikhali kukutywina imathiriyeli.Ngenxa yokusebenza kwayo kakuhle okubanzi, i-PTFE ayinakuthelekiswa nalo naluphi na uhlobo lwemathiriyeli yokutywina.Ingasetyenziselwa ukutywina kwiimeko ezahlukeneyo ezinzima, ngakumbi xa ubushushu obuphezulu kunye nokuxhathisa umhlwa kuyadingeka.
Iteyiphu yeTeflon inefiber ende, amandla aphezulu, iplastikhi ephezulu kunye necalendability entle, kwaye inokutywinwa ngokupheleleyo ngokusebenzisa amandla amancinci ocinezelo.Kukulungele ukusebenza kunye nokufaka isicelo, kwaye kusebenza ngakumbi xa kusetyenziswe kwiindawo ezingalinganiyo okanye ezichanekileyo.Inokusebenza kakuhle kokutywinwa, inokuphucula ukuxhathisa ukubola kunye nokwandisa uluhlu lwesicelo sayo.Ukupakishwa kwe-PTFE kusetyenziselwa ukutywinwa kwamalungu atyibilikayo, anokufumana ukuxhathisa okulungileyo kunye nozinzo, kwaye inobunzima obuthile kunye nokomelela, kunye nokuchasana okuncinci xa utyibilika.Izinto zokutywina ezizaliswe yi-PTFE inoluhlu olubanzi lobushushu besicelo, eyona ndawo iphambili ye-asbestos gasket imathiriyeli yemveli okwangoku.Ikwanayo neempawu zemodyuli ephezulu, amandla aphezulu, ukuxhathisa ukukhwela, ukuxhathisa ukukhathala, ukuhanjiswa okuphezulu kwe-thermal, i-coefficient ephantsi yokwandiswa kwe-thermal kunye ne-friction, njl.
