Polytetrafluoroethylene ntawv (tseem hu ua tetrafluoroethylene ntawv, Teflon ntawv, Teflon ntawv) muab faib ua ob hom: molded thiab tig. Nws cov khoom siv dav siv thiab muaj cov khoom zoo tshaj plaws: siab thiab qis kub tsis kam (-192 degree -260 degree), corrosion resistance (muaj zog acid, muaj zog alkali, aqua regia, thiab lwm yam), huab cua tsis kam , siab rwb thaiv tsev, siab lubricity, tsis-adhesion, non-toxic thiab lwm yam zoo heev yam ntxwv. Polytetrafluoroethylene (abbreviated li Teflon lossis [PTFE, F4] hauv lus Askiv) yog lub npe hu ua "King of Plastics". Nws cov khoom suav npe yog "Teflon", "Teflon" (teflon), "Teflon", "Teflon", "Teflon", "Teflon", thiab lwm yam.
Nws yog ib tug polymer compound tsim los ntawm lub polymerization ntawm tetrafluoroethylene, thiab nws cov qauv qauv yog -[-CF2-CF2-]n-, nrog zoo heev tshuaj stability thiab corrosion kuj (PTFE los yog F4, abbreviated li. polytetrafluoroethylene, yog ib qho ntawm cov khoom siv corrosion-resistant tshaj plaws nyob rau hauv lub ntiaj teb niaj hnub no "Plastic King" yog lub npe nrov rau polytetrafluoroethylene, uas yog cov yas uas muaj qhov zoo tshaj plaws corrosion tsis kam ntawm cov kua qaub, alkalis, ntsev, thiab oxidants, thiab txawm aqua regia tsis pab tiv thaiv nws, yog li nws yog lub npe hu ua Plastic King Tsuas yog molten hlau sodium thiab kua fluorine, nws muaj peev xwm tiv taus tag nrho lwm yam tshuaj , sealing, siab lubrication thiab tsis-stickiness, hluav taws xob rwb thaiv tsev thiab zoo anti-aging kuj, zoo heev kub kuj (tuaj yeem ua hauj lwm ntev ntawm qhov kub ntawm +250 degree rau -180 degree ).
Siv Daim Ntawv Thov:
Txhua yam khoom ntawm polytetrafluoroethylene tau ua lub luag haujlwm tseem ceeb hauv kev lag luam hauv tebchaws xws li kev lag luam tshuaj lom neeg, tshuab, hluav taws xob, khoom siv hluav taws xob, kev lag luam tub rog, kev lag luam aerospace, kev tiv thaiv ib puag ncig thiab txuas hniav.
PTFE ntawv yog tsim rau qhov kub thiab txias ntawm -180 degree ~ +250 degree . Lawv tsuas yog siv los ua hluav taws xob rwb thaiv tsev cov ntaub ntawv thiab cov ntaub ntawv, txhawb nqa sliders, rail seals thiab lubricating cov ntaub ntawv rau kev sib cuag nrog corrosive media. Fugui rooj tog siv nws hauv kev lag luam teeb. Nws yog dav siv nyob rau hauv tshuaj, tshuaj, tshuaj pleev ib ce kev lag luam ntim, cia tso tsheb hlau luam, tshuaj tiv thaiv ntauwd kettles, thiab anti-corrosion hauv ob sab phlu cov ntaub ntawv rau loj pipelines; aviation, tub rog thiab lwm yam kev lag luam hnyav; machinery, kev tsim kho, kev thauj mus los choj sliders, qhia rails; luam ntawv thiab dyeing, lub teeb kev lag luam, textile kev lag luam los tiv thaiv cov ntaub ntawv, thiab lwm yam.
