PTFEyisiqina se-fluorocarbon, njengoko iyikhompawundi enobunzima obuphezulu bemolekyuli equlathe ngokupheleleyo ikharbhon kunye nefluorine.I-PTFE i-hydrophobic: ayingomanzi okanye izinto eziqulathe amanzi zimanzi i-PTFE, njengoko iifluorocarbons zibonisa amandla okusasazwa eLondon ngenxa ye-electronegativity ephezulu yefluorine.I-PTFE ineyona coefficients isezantsi yokukhuhlana kwayo nayiphi na into eqinileyo.
I-PTFE yimathiriyeli eguquguqukayo efumaneka kwizicelo ezininzi ze-niche:
Ihlala ifumaneka kwi-ski bindings njenge-AFD engeyiyo eyomatshini (Isixhobo esichasene neFriction)
Inokolulwa ukuze iqulathe imingxuma emincinci yobukhulu obahlukeneyo kwaye emva koko ibekwe phakathi kwelaphu lelaphu ukwenza ilaphu elingangeni manzi, eliphefumlayo kwimpahla yangaphandle.
Isetyenziswa ngokubanzi njengesikhuseli selaphu ukugxotha amabala kwisinxibo sesikolo esisesikweni, njengeeblazi zeyunifomu.
Isetyenziswa njengendawo yojongano lwefilimu kwimidlalo kunye nezicelo zonyango, ebonisa i-adhesive-sensitive backing backing, efakwe kwiindawo ezicwangcisiweyo zokukhuhlana kwezihlangu, ii-insoles, i-ankle-foot orthosis, kunye nezinye izixhobo zonyango ukuthintela kunye nokunciphisa ukungqubana- amadyungudyungu, amaqhakuva kunye nezilonda ezinyaweni.
Iimbrane ze-PTFE ezandisiweyo zisetyenziswe kwizilingo zokunceda utyando lwe-trabeculectomy ukunyanga i-glaucoma.
I-PTFE yomgubo isetyenziselwa ukuqamba i-pyrotechnic njenge-oxidizer kunye neentsimbi ezinomgubo ezifana ne-aluminiyam kunye ne-magnesium.Ekutshisweni, le mixube yenza i-carbonaceous soot kunye ne-metal fluoride ehambelanayo, kwaye ikhuphe ubushushu obukhulu.Zisetyenziswa kwi-infrared decoy flares kwaye njenge-igniters ye-rocket-fuel propellants.
I-PTFE yomgubo isetyenziselwa ukunqunyanyiswa nge-low-viscosity, umxube we-azeotropic we-siloxane ethers ukwenza isithambisi esisetyenziswa kwiiphazili ezijijekileyo.
Kwiradiometry yokubona, amaphepha e-PTFE asetyenziswa njengeentloko zokulinganisa kwi-spectroradiometers kunye neeradiometers zebroadband (umzekelo, iimitha zokukhanya kunye neeradiometers ze-UV) ngenxa yesakhono se-PTFE sokusasaza ukukhanya okusasaza phantse ngokugqibeleleyo.Ngapha koko, iipropathi ezibonakalayo ze-PTFE zihlala zingaguquguquki kuluhlu olubanzi lwamaza amaza, ukusuka kwi-UV ukuhla ukuya kufutshane ne-infrared.Kulo mmandla, unxulumano losasazo oluqhelekileyo lokusasaza usasazo luncinci ngokungenankathalo, ngoko ke ukukhanya okugqithiselwa nge-diffuser (iphepha le-PTFE) kukhanya njengomthetho we-cosine kaLambert.Ngaloo ndlela i-PTFE yenza ukuba i-cosinusoidal iphendule i-angular kwi-detector yokulinganisa amandla okukhanya kwe-optical radiation kumphezulu, umz. kwimilinganiselo ye-solar irradiance.
Iintlobo ezithile zeembumbulu zigqunywe nge-PTFE ukunciphisa ukuguga kwimipu enokuthi ibangele iiprojekthi ezingagqunywanga.I-PTFE ngokwayo ayiniki projectile ipropati yokugqobhoza izixhobo.
Ukumelana ne-corrosion yayo ephezulu kwenza i-PTFE ibe luncedo kwiindawo zaselabhoratri, apho isetyenziselwa izikhongozeli ze-lining, njenge-coating ye-magnetic stirrers, kunye ne-tubing yeekhemikhali eziyingozi kakhulu ezifana ne-hydrofluoric acid, eya kunyibilikisa izitya zeglasi.Isetyenziswa kwizikhongozeli zokugcina i-fluoroantimonic acid, i-superacid.
Iityhubhu ze-PTFE zisetyenziswa kwirhasi-yerhasi yokutshintshiselana kobushushu ekucoceni irhasi kwizitshisi zenkunkuma.Umthamo wamandla weyunithi uqhelekile ziimegawathi ezininzi.
I-PTFE isetyenziswa ngokubanzi njenge tape yokutywina kwimibhobho yezicelo, ubukhulu becala ithatha indawo ye-dope yentambo yokucola.
Izihluzi ze-membrane ze-PTFE ziphakathi kwezona zihluzo zomoya ezisebenzayo kwimizi-mveliso.Izihluzi ezigqunywe nge-PTFE zisoloko zisetyenziswa kwiinkqubo zokuqokelelwa kothuli ukuqokelela into ethile evela kwimisinga yomoya kwizicelo ezibandakanya amaqondo obushushu aphezulu kunye nemithwalo ephezulu efana nezityalo zamandla omlilo wamalahle, imveliso yesamente kunye neziseko zentsimbi.
I-PTFE grafts ingasetyenziselwa ukudlula imithambo ye-stenotic kwi-peripheral vascular disease ukuba i-autologous vein graft ayifumaneki.
Izithambisi ezininzi zebhayisekile kunye namafutha ziqulathe i-PTFE kwaye zisetyenziswa kumatyathanga kunye namanye amalungu ashukumayo aphantsi koxinzelelo lokukhuhlana (okufana neebheringi zehub).
I-PTFE ingasetyenziselwa ukuzaliswa kwamazinyo, ukwahlula abafowunelwa bezinyo langaphambili ukuze izinto zokuzalisa zingabambeleli kwizinyo elikufutshane.
Amaphepha e-PTFE asetyenziswa kwimveliso ye-oyile ye-butane ye-hash ngenxa yeempawu zayo zokungakhuni kunye nokuchasana nezinyibilikisi ezingezizo ezipolar.
I-PTFE, eyayanyaniswa nelaminate ebhalwe kancinci, yenza inkqubo yokuthwala ecacileyo yeteleskopu yeDobsonia.
I-PTFE isetyenziswa ngokubanzi njengento yokugquma intonga kwizixhobo zokulungisa ukutya;iihoppers zentlama, izitya zokuxuba, iinkqubo zokuhambisa, iirola, kunye neechute.I-PTFE inokomelezwa apho i-abrasion ikhona - ukulungiselela izixhobo zokulungisa imbewu okanye intlama yengqolowa umzekelo
