Cov ntaub ntawv raw ntawm PTFE gaskets yuav tsum tiv taus cov tshuaj corrosion thiab lub cev corrosion.Kev tsim nyog gaskets yuav tsum tau siv raws li qhov tseeb kev khiav hauj lwm hom tshuaj thiab cov yam ntxwv corrosion, thiab tom qab ntawd cov hydrodynamic corrosion kuj ntawm gasket raw cov ntaub ntawv yuav tsum tau txiav txim siab.Lub hydrodynamic corrosion kuj yog feem ntau qhia los ntawm kev nce hauv thickness thiab net hnyav ntawm cov khoom gasket tom qab ua kua infiltration.Rau gaskets uas kov cov ntaub ntawv uas tsis yog-yas, tswj kom zoo thickness nce tus nqi ntawm cov ntaub ntawv gasket yog qhov zoo rau kev txhim kho sealing kev ua tau zoo nyob rau hauv lub premise ntawm kom ntseeg tau lwm yam khoom.
Lub creep so tus nqi ntawm PTFE gasket yog qhov tseem ceeb parameter rau kev soj ntsuam zoo ntawm kev ua tau zoo ntawm cov khoom siv gasket.Nws qhia txog lub peev xwm ntawm cov khoom siv gasket los tiv thaiv kev ntxhov siab so thiab nkag deformation.dav dav.Qhov me me ntawm qhov nkag mus rau qhov sib piv, qhov ntau dua qhov kev ntxhov siab sab hauv thaum ua haujlwm.Qhov zoo dua qhov sealing kev ua tau zoo yog rau cov tsis-asbestos gaskets.Creep so yog qhov laj thawj tseem ceeb rau kev xau ntawm lub voj voog flange thaum lub sijhawm ua haujlwm.Nws plays ib qho kev txiav txim siab ntawm qhov kev pab cuam lub neej ntawm kev sib txuas.Lub shrinkage kev ua tau zoo ntawm PTFE gasket qhia txog qhov ductility lossis yas deformation ntawm lub gasket nyob rau hauv cov nyhuv ntawm lub sijhawm thauj khoom.Txhawm rau tsim kom muaj ntau yam tsis txaus ntawm flange nto.Nyob rau hauv lem, kev ua tau zoo ntawm kev tiv thaiv to.
Feem ntau hais lus, feem ntau ntawm shrinking kev ua tau zoo ntawm cov uas tsis yog-asbestos gaskets yuav raug txiav txim siab rau cov kev cai sealing.Piv nrog rau kev nthuav dav, qhov kev ua tau zoo ntawm kev ua haujlwm yog qhov tseem ceeb tshaj plaws ntawm qhov ntsuas tus nqi.Qhov kev ua tau zoo resilience yog hais txog kev them nyiaj ductility ntawm lub gasket, uas tuaj yeem ua raws li kev sib cais ntawm flange vim qhov kub thiab txias los yog cov khoom siv kho tshuab thauj khoom los tuav lub foob.Qhov kev ua tau zoo ntawm PTFE gasket yog qhov tseem ceeb ntawm kev ua tau zoo ntawm qhov zoo ntawm lub gasket, thiab tus nqi xau yog qhov ntsuas qhov muag pom.Raws li tus nqi xau tus nqi ntsuas, lub peev xwm sealing ntawm lub gasket tuaj yeem txheeb xyuas ntau thiab sib piv.Tus nqi xau yog qhov tseem ceeb parameter uas yuav tsum tau xav txog thaum xaiv cov gaskets.
4 Yam Yuav Tsum Muaj Kev txhawj xeeb thaum txhim kho PTFE Gaskets
1. Lub sealing kab los yog tsa saum npoo ntawm PTFE gasket foob yuav tsum tsis txhob puas.Lub PTFE gasket foob nyob rau hauv txoj kev npaj saib yuav siv sab laug thiab sab hauv qhov.Lub sealing kev ua tau zoo ntawm PTFE gasket foob ntawm lub tshuab hydraulic yog tsuas yog nyob ntawm tus ncej lossis lub qhov.Ib txoj kab uas zoo sib xws yuav tsum tau ceev faj heev nyob rau hauv tag nrho cov txheej txheem ntawm kev teeb tsa, kev thauj mus los, thiab kev cia khoom.Qhov no yog ua los ntawm cov mos mos thiab resilient high-purity graphite, tshuaj fiber ntau, roj hmab, thiab yas uas tiv taus corrosion, kub kub thiab kev laus.Rwb thaiv tsev board thiab lwm yam xws li cov ntaub ntawv tsis yooj yim yog tsim los ntawm cov ntaub ntawv, yog li ib zaug puas lawm, nws yuav ua rau muaj kev phom sij loj heev rau qhov sib khi.
2. Thaum txhim kho PTFE gasket seals, peb yuav tsum tau ceev faj heev, thiab cov txheej txheem ntxig yuav tsum maj mam nqa tawm.Thaum lub sij hawm tag nrho cov txheej txheem installation, tsis txhob yuam lub installation nrog lub cev loj heev, uas yuav ua rau txhua tus PTFE gasket seals.Thawj cov qauv prefabricated tau raug rhuav tshem.
3. Kev teeb tsa ntawm PTFE gasket seals yuav tsum ua raws li qhov sib npaug thiab sib npaug.Thaum txhim kho, tso lub PTFE gasket foob rau ntawm txoj hauj lwm ntawm qhov daig di ncauj nto (los yog tsim nyog tsa saum npoo) kom tsis txhob muaj qhov system software ua haujlwm Thaum lub sij hawm tag nrho cov txheej txheem, vim yog kev hloov pauv (piv txwv li, nce) ntawm nws cov kev ua haujlwm, qhov ua tsis tiav. los ntawm micro-leakage tshwm sim.Nws yog ib qho tsim nyog yuav tsum tau soj ntsuam tas li thiab ua haujlwm zoo hauv cov kauj ruam tom ntej ntawm PTFE gasket foob.
4. Lub PTFE gasket muaj kev ua tau zoo, ua haujlwm kub, tiv thaiv corrosion, tsis-stick, nws tus kheej lubricating, electrochemical kev ua tau zoo, thiab tsis tshua muaj kev sib txhuam.
Raws li cov khoom siv roj hmab, hloov kho PTFE gaskets tuaj yeem ua rau hauv cov kav dej polytetrafluoroethylene, rods, siv, daim hlau, yas zaj duab xis, thiab lwm yam. Lawv feem ntau yog siv rau hauv cov kav dej corrosion-resistant, tais diav, twj tso kua mis, li qub thiab lawv tswj radar nrhiav kom tau, kev sib txuas lus siab. khoom siv, khoom siv sib txuas lus wireless, thiab lwm yam.
Tag nrho cov muab tub lim uas tuaj yeem dais qhov kub thiab txias ntawm PTFE ntxiv rau qhov hloov kho tetrafluoroethylene gasket.Cov khoom ntim khoom muaj xws li iav fiber ntau, cov khoom siv hlau, cov hlau hlau oxides, high-purity graphite, molybdenum disulfide, carbon fiber mos, Polyimide zaj duab xis, thiab lwm yam.Tsis tas li ntawd, lwm yam khoom ntawm PTFE tuaj yeem khaws cia, thiab hnav tsis kam thiab PV tus nqi tuaj yeem nce 1000 zaug.
