polymer daim kab xev yog ib hom tshwj xeeb ntawm daim kab xev siv hauv cov kav dej kom kaw cov kev sib txuas kom huv si, kom ntseeg tau tias cov kav dej yuav tsis xau.Daim kab xev no tseem hu ua poly (tetrafluoroethylene) (PTFE) daim kab xev, nrog polymer yog ib lub cim lag luam ntawm DuPont tuam txhab.
PTFE yog ib yam khoom zoo heev.Los ntawm cov kav dej pom, nws tseem ceeb heev uas yuav tsum nco ntsoov tias nws hloov tau yooj yim thiab nws muaj lub zog tensile loj heev.Thaum cov ntaub nplaum polymer siv los qhwv cov xov ntawm cov yeeb nkab, daim kab xev ua haujlwm yuav luag zoo li putty, sau qhov chaw thiab tiv thaiv kom tsis txhob tawm.Thaum nws tuaj yeem siv cov kav dej tso rau cov dej num zoo li no, cov ntaub nplaum polymer yog sai dua thiab yooj yim dua, thiab feem ntau zoo dua, thiab.
Feem ntau,PTFE daim kab xevyog dawb, vim qhov no yog cov xim ntuj ntawm cov khoom.Qee lub tuam txhab ua cov xim coded PTFE daim kab xev, nrog cov xim sib txawv tsim los rau ntau hom kav dej.Cov ntaub nplaum polymer siv rau cov kav dej siv roj, piv txwv li, yog tuab dua los tiv thaiv cov pa paug, thiab nws yuav yog xim xiav lossis daj.Cov ntaub nplaum tsis yog nplaum, nyiam tuav nrog lub siab tab sis yooj yim txav thiab rov ua dua.
Daim kab xev no yog tsim los siv rau hauv cov kav dej nrog cov xov tapered.Tapered kav yog zoo tagnrho rau ua ib tug nruj sealing vim hais tias cov tapered tsim tsim ib tug wedge nyhuv, sealing cov yeeb nkab kom huv si kom tsis muaj dab tsi tuaj yeem tawm.Txhawm rau siv daim kab xev, qhov ntev yog qhwv ib ncig ntawm tus txiv neej lossis threaded kawg ntawm cov yeeb nkab, thiab tom qab ntawd tus poj niam kawg ntawm cov yeeb nkab txuas nrog.Nws yog ib qho tseem ceeb kom paub tseeb tias cov ntaub nplaum polymer tsis sib tshooj nrog qhov kawg ntawm cov yeeb nkab, vim qhov no tuaj yeem ua teeb meem rau yav tom ntej, vim tias daim kab xev yuav thaiv cov yeeb nkab.
polymer daim kab xev yog ib qho tseem ceeb heev rau khaws cia nyob ib ncig ntawm lub tsev.Txawm hais tias tus neeg siv kav dej yuav tau sab laj los kho qhov teeb meem, daim kab xev tuaj yeem siv los kho sai kom khaws cov khoom kom txog thaum tus kav dej tuaj txog.Cov tib neeg yuav tsum tau ceev faj heev nyob ib puag ncig cov kav dej, vim tias cov pa xau tuaj yeem ua rau muaj kev phom sij heev, thiab lawv yuav tsum tau saib xyuas los ntawm cov kws tshaj lij.Yog tias xav tias muaj roj xau, cov roj yuav tsum raug muab tua thiab tus kws tshaj lij roj yuav tsum raug hu tam sim ntawd.
PTFE ua haujlwm li cas
Txwv tsis pub hu ua xov foob daim kab xev, PTFE daim kab xev yog siv rau ntawm tus txiv neej kawg ntawm cov kav dej (lub npe hu ua threads) ua ntej lawv txuas nrog lwm cov kav dej.Cov zaj duab xis yog tsim los ntawm polytetrafluoroethylene (PTFE), ib tug hluavtaws zoo hu ua polymer.Vim hais tias cov khoom no yog impermeable thiab malleable, nws tsim rau hauv cov khoom zoo li putty tom qab nws qhwv ib ncig ntawm cov yeeb nkab threads thiab screwed rau lwm cov kav dej.Kev sib txhuam los ntawm kev sib tsoo cov kav dej ua ke ua rau cov xov kab sib txuas, tsim kom muaj lub foob airtight thiab ua kom cov kav dej sib txuas kom zoo.
PTFE daim kab xev tsuas yog ua haujlwm ntawm tapered threads as opposed to parallel threads.Qhov no yog vim hais tias daim kab xev ua haujlwm tawm ntawm kev sib txhuam tsim los ntawm tapered threads.Xov kab xev ua haujlwm raws li lub sealant vim nws tus kheej lubricates raws li nws tau ntsib nrog kev sib txhuam.Kev siv PTFE daim kab xev ntau dhau tuaj yeem ua rau muaj kev phom sij, vim tias cov khoom siv ntau dhau tuaj yeem oze tawm ntawm cov kav dej, ua rau muaj cov tshuaj phem.
Siv PTFE daim kab xev
Ib qho tseem ceeb ntawm PTFE daim kab xev yog kom paub tseeb tias koj siv tus nqi tsim nyog.Qhov zoo tshaj plaws tus nqi yog ob zaug nyob ib ncig ntawm cov yeeb nkab nyob rau hauv opposite kev coj ntawm cov xov.Yog tias koj pom tias koj tau muab cov xov xov tsis raug thiab cov yeeb nkab txuas txuas tsis raug, koj tuaj yeem pom koj tus kheej nrog qhov teeb meem nyuaj.Cov kav dej yuav nruj heev kom tsis txhob ntsia hlau.Txawm li cas los xij, koj tuaj yeem kho qhov no los ntawm kev tshem tawm cov khoom siv uas muaj cov yeeb nkab thiab muab lub hau ntsaws rau hauv kev sib txuas thiab rub nws qhib.
Hom PTFE Daim kab xev
PTFE daim kab xev los ntawm ntau yam xim, ntom thiab tuab.Rau cov dej num yooj yim tshaj plaws, koj yuav siv tau cov qauv, dawb PTFE daim kab xev.Txawm li cas los xij, rau cov kab hluav taws xob thiab kev ua haujlwm txaus ntshai, ib hom xov xov tshwj xeeb yuav tsim nyog.Cov xim ntawm daim kab xev tsis cuam tshuam rau nws qhov kev ua tau zoo, tab sis tuaj yeem raug xaiv raws li xim ntawm koj cov yeeb nkab.Muaj cov qauv hauv qhov chaw uas txiav txim siab kev faib tawm ntawm PTFE daim kab xev, coj mus rau hauv tus account yam xws li qhov dav thiab qhov ceev.
