Polytetrafluoroethylene (PTFE) yog tam sim no feem ntau siv cov fluoropolymer, yog cov tshuaj tiv thaiv corrosion, muaj qhov zoo tshaj plaws dielectric zog thiab ntau yam kev ua haujlwm kub ntau yam, hu ua "king of plastics".
PTFE muaj qhov kub thiab txias tsis kam (tuaj yeem siv tau ntev hauv qhov ntsuas kub ntawm 200 ~ 260 ℃), tsis kub tsis kam (tuaj yeem siv tau ntev hauv qab -100 ℃), corrosion kuj (nrog rau cov tshuaj inertness siab), huab cua tsis kam (siab atmospheric aging kuj), siab lubrication (nrog me me coefficient ntawm kev sib txhuam), non-adhesive (nroj nro yog heev tsawg, tsis yooj yim rau adhere), zoo tib neeg compatibility (nrog zoo physiological inertness, non-toxic) , zoo hluav taws xob rwb thaiv tsev (siab rwb thaiv tsev, thiab tsis cuam tshuam los ntawm kub, av noo) thiab ib tug series ntawm zoo,PTFE, cov yam ntxwv no muaj feem xyuam nrog nws cov qauv molecular.
Tshuaj teb
PTFE tsis yaj los yog o nyob rau hauv ib yam ntawm cov kua paub, yog liPTFEqhov chaw tsis hloov qhov loj me hauv qhov nruab nrab corrosive, txawm tias lawv siv sijhawm ntev npaum li cas.PTFE ua cov thawv loj nyias-walled uas tau siv dav hauv cov chaw soj nstuam thiab cov chaw tsim khoom uas siv cov kua corrosive, thiab nws kuj tau siv dav hauv cov ntsaws ruaj ruaj, yeeb nkab hauv ob sab phlu, twj, li qub, thiab lwm yam.
Mechanical teb
Tsis muaj teeb meem dab tsi ntawm cov tshuab thiab cov khoom siv, cov zawv zawg qhov chaw yuav tsum tau lubricated kom txo tau qhov kev sib txhuam, hnav thiab cua sov kom ntseeg tau tias kev ua haujlwm ntawm cov tshuab thiab cov cuab yeej muaj peev xwm, raug thiab siv zog.PTFE tsis tshua muaj coefficient ntawm kev sib txhuam thiab nws tus kheej-lubricating zog ua rau nws lug siv nyob rau hauv lub tsim ntawm bearings, piston rings, tshuab cuab yeej qhia thiab sealing cov ntaub ntawv, tab sis vim hais tias nws yog kim kim, nws yog feem ntau siv nyob rau hauv precision instruments los yog xav tau acid thiab alkali resistant. ib puag ncig.
Hluav taws xob teb
PTFE zoo heev dielectric zog, uas yog zoo li ywj siab ntawm kub thiab zaus, raws li zoo raws li nws siab thermal stability, ua rau nws ib tug irreplaceable hluav taws xob insulator, tshwj xeeb tshaj yog nyob rau hauv high zaus thiab kub thiab nyob rau hauv ib puag ncig ntub.
Niaj hnub no ntau hom PTFE cov ntaub ntawv ua lub luag haujlwm tseem ceeb hauv kev rwb thaiv tsev hluav taws xob thiab hluav taws xob.PTFE iav lacquer daim ntaub thiab cov ntaub iav yog siv los ua cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob siab, uas tuaj yeem siv hauv kev sib txuas lus satellite thiab khoos phis tawj.PTFE zaj duab xis yog siv los ua cov capacitors, ua ib txheej rwb thaiv tsev ntawm cov twj paj nruag, gaskets, cables, thiab lwm yam.PTFEnyias-walled raj ntawm txawv diameters yog siv rau cov hlau lead-hauv tes tsho, tshav kub-shrinkable raj thiab kauv raj, insulated pilot tube rau generators, thiab lwm yam.
PTFE yog ib qho khoom siv zoo heev, nws muaj peev xwm tos ntau tus neeg los tshawb nrhiav.Cov kws tshaj lij ntawm cov ntaub ntawv tshiab yuav tsum tsis yog tsuas yog paub txog cov khoom ntawm cov ntaub ntawv, tab sis kuj ua kom lawv cov yam ntxwv zoo tshaj plaws los muab ntau yam kev ua rau peb lub neej zoo dua.
