PTFENws yog cov khoom siv fluorocarbon, vim nws yog cov khoom hnyav molecular uas muaj cov pa roj carbon thiab fluorine tag nrho.PTFE yog hydrophobic: tsis yog dej los yog dej-muaj tshuaj ntub dej PTFE, raws li fluorocarbons qhia mitigated London dispersion rog vim lub siab electronegativity ntawm fluorine.PTFE muaj ib qho qis tshaj coefficients ntawm kev sib txhuam ntawm cov khoom.
PTFE yog cov khoom siv ntau yam uas muaj nyob hauv ntau daim ntawv thov niche:
Nws feem ntau pom nyob rau hauv kev sib tw caij ski raws li cov khoom siv tsis yog AFD (Anti-Friction Device)
Nws tuaj yeem ncab kom muaj cov pores me me ntawm qhov sib txawv thiab tom qab ntawd muab tso rau ntawm cov khaubncaws sab nraud povtseg los ua cov ntaub tsis muaj dej, ua pa tawm hauv cov khaub ncaws sab nraum zoov.
Nws yog siv dav los ua cov ntaub tiv thaiv los tiv thaiv cov kab mob ntawm cov tsev kawm ntawv-hnav, zoo li cov tsho blazers.
Nws yog siv los ua ib zaj duab xis interface rau kev ua kis las thiab kev siv kho mob, uas muaj lub siab-rhiab nplaum rov qab, uas yog ntsia rau hauv cov kev sib txhuam siab ntawm cov khau, insoles, pob taws-ko taw orthosis, thiab lwm yam khoom siv kho mob los tiv thaiv thiab txo kev sib txhuam- induced hlwv, calluses thiab ko taw ulceration.
Nthuav PTFE membranes tau siv nyob rau hauv kev sim los pab trabeculectomy phais los kho glaucoma.
Powdered PTFE yog siv nyob rau hauv pyrotechnic compositions ua oxidizer nrog hmoov hlau xws li txhuas thiab magnesium.Thaum hluav taws kub, cov khoom sib tov no tsim cov pa roj carbonaceous thiab cov hlau fluoride, thiab tso tawm cov cua kub ntau.Lawv yog siv nyob rau hauv infrared decoy flares thiab ua igniters rau khoom-roj foob pob hluav taws propellants.Aluminium thiab PTFE kuj yog siv nyob rau hauv ib co thermobaric roj compositions.
Powdered PTFE yog siv nyob rau hauv lub ncua kev kawm ntawv nrog ib tug tsawg-viscosity, azeotropic sib tov ntawm siloxane ethers los tsim ib tug lubricant rau siv nyob rau hauv twisty puzzles.
Nyob rau hauv optical radiometry, nplooj ntawv ntawm PTFE yog siv los ntsuas lub taub hau nyob rau hauv spectroradiometers thiab broadband radiometers (xws li, illuminance meters thiab UV radiometers) vim PTFE lub peev xwm mus diffuse ib tug transmitting lub teeb yuav luag tag nrho.Tsis tas li ntawd, cov khoom kho qhov muag ntawm PTFE nyob tsis tu ncua ntawm ntau lub wavelengths, los ntawm UV mus rau ze infrared.Hauv cheeb tsam no, kev sib raug zoo ntawm nws cov kev sib kis tsis tu ncua rau diffuse transmittance yog negligibly me me, yog li lub teeb kis tau los ntawm diffuser (PTFE ntawv) radiates zoo li Lambert txoj cai cosine.Yog li PTFE enables cosinusoidal angular teb rau ib tug detector ntsuas lub hwj chim ntawm optical hluav taws xob ntawm ib tug nto, xws li nyob rau hauv lub hnub ci irradiance ntsuas.
Qee hom mos txwv yog coated nrog PTFE kom txo tau hnav ntawm rab phom phom uas tsis muaj coated projectiles yuav ua rau.PTFE nws tus kheej tsis muab ib qhov projectile ib armor-piercing cuab yeej.
Nws lub siab corrosion kuj ua rau PTFE pab tau nyob rau hauv ib puag ncig kev kuaj, qhov twg nws yog siv rau hauv ob sab phlu ntim, raws li ib tug txheej rau sib nqus stirrers, thiab raws li tubing rau heev corrosive tshuaj xws li hydrofluoric acid, uas yuav yaj iav ntim.Nws yog siv nyob rau hauv ntim rau khaws cia fluoroantimonic acid, ib tug superacid.
PTFE raj yog siv nyob rau hauv cov pa roj cua kub exchangers nyob rau hauv cov pa ntxuav ntawm cov khib nyiab incinerators.Chav tsev fais fab muaj peev xwm feem ntau yog ob peb megawatts.
PTFE yog dav siv raws li ib tug xov seal daim kab xev nyob rau hauv cov kav dej daim ntaub ntawv, loj hloov paste xov dope.
PTFE membrane lim yog ib qho ntawm cov khoom siv lim cua zoo tshaj plaws.PTFE-coated cov ntxaij lim dej feem ntau siv rau hauv cov khoom siv plua plav los khaws cov khoom me me los ntawm cov huab cua hauv cov ntawv thov uas muaj qhov kub thiab txias siab xws li cov chaw tsim hluav taws xob hluav taws xob, cov cement ntau lawm thiab cov chaw tsim khoom steel.
PTFE grafts tuaj yeem siv los hla cov hlab ntsha stenotic hauv peripheral vascular kab mob yog tias tsis muaj qhov tsim nyog autologous leeg graft tsis muaj.
Ntau lub tsheb kauj vab lubricants thiab roj muaj PTFE thiab siv rau ntawm cov saw thiab lwm yam txav mus los ntawm kev sib txhuam quab yuam (xws li hub bearings).
PTFE kuj tseem siv tau rau kev kho hniav, cais cov neeg ntawm cov hniav sab hauv kom cov ntaub ntawv sau yuav tsis lo rau cov hniav uas nyob ib sab.
PTFE nplooj ntawv yog siv nyob rau hauv zus tau tej cov butane hash roj vim nws cov khoom tsis-stick thiab tsis kam mus rau non-polar solvents.
PTFE, cuam tshuam nrog me ntsis textured laminate, ua rau cov kabmob dawb ntawm Dobsonian telescope.
PTFE yog dav siv los ua cov txheej tsis lo rau cov khoom siv ua zaub mov;khob noom cookie hoppers, sib tov tais, conveyor systems, rollers, thiab chutes.PTFE kuj tseem tuaj yeem txhawb ntxiv qhov twg muaj kev puas tsuaj - rau cov cuab yeej ua cov noob qoob loo lossis cov khob noom cookie piv txwv
