Nyob rau hauv ib puag ncig kub, kev ua haujlwm ruaj khov ntawm PTFE seals (PTFE) yog qhov tseem ceeb hauv kev ua kom muaj kev nyab xeeb ntawm kev lag luam khoom siv. Paub txog nws qhov kev ua tau zoo ntawm qhov kub thiab txias, kev ruaj ntseg tshuaj, thiab tsis tshua muaj coefficient ntawm kev sib txhuam, PTFE yog cov khoom sib khi ntawm kev xaiv rau ntau daim ntawv thov kub. Txawm li cas los xij, nrog kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho kev lag luam, cov kev xav tau siab dua tau muab tso rau pem hauv ntej rau kev ua haujlwm ruaj khov ntawm PTFE seals ntawm qhov kub thiab txias.
Kev ua tau zoo stability teeb meem nyob rau hauv high-temperature ib puag ncig
Thermal expansion thiab deformation
Txawm hais tias PTFE muaj qhov zoo ntawm qhov ruaj khov ntawm qhov kub thiab txias, me me thermal expansion lossis deformation tseem tuaj yeem tshwm sim nyob rau hauv qhov kub thiab txias (xws li, dhau 260 degree), uas tuaj yeem cuam tshuam cov nyhuv sealing.
Tshuaj tua kab mob
Thaum PTFE muaj cov tshuaj tiv thaiv zoo heev rau feem ntau cov tshuaj, nws cov tshuaj ruaj khov tuaj yeem sib tw hauv qee qhov chaw huab cua lossis cov tshuaj lom neeg tshwj xeeb, xws li nyob rau hauv muaj cov tshuaj oxidizing muaj zog.
Cov kev hloov hauv lub zog txhua yam
Kev siv qhov kub thiab txias ntev ntev yuav ua rau txo qis ntawm cov khoom siv dag zog ntawm PTFE seals, uas cuam tshuam rau lawv cov sealing kev ua tau zoo thiab kev pabcuam lub neej.
Kev daws
Kev hloov khoom siv
PTFE tau hloov kho los ntawm kev nthuav qhia cov fibers ntxiv (piv txwv li, iav fibers, carbon fibers) los yog nanoparticles los txhim kho nws qhov kub thiab txias thiab lub zog txhua yam. Piv txwv li, nanocomposite PTFE cov ntaub ntawv muaj peev xwm tuav tau zoo seem stability thiab txhua yam khoom saum toj no 300 degree.
Optimize tus qauv tsim
Tsim cov qauv sealing tsim nyog dua, xws li kev siv ntau txheej txheej sealing qauv, siv cov khoom sib txawv los ua kom tiav ib leeg, txhim kho kev sib khi tag nrho. Nyob rau tib lub sijhawm, kev tsim cov cua sov dissipation yog nce ntxiv kom txo tau qhov kub thiab txias hauv zos ntawm lub foob thiab ua rau lub neej ntev kev pab cuam.
Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua
Tsim kom muaj kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua, ua cov kev tshuaj xyuas tsis tu ncua ntawm PTFE cov ntsaws ruaj ruaj nyob rau hauv qhov chaw kub kub, thiab nrhiav thiab daws cov teeb meem tshwm sim raws sijhawm. Niaj hnub nimno tshawb nrhiav technologies, xws li infrared thermography, yog siv los saib xyuas qhov kub thiab txias ntawm cov ntsaws ruaj ruaj thiab tiv thaiv thermal expansion thiab deformation.
Cov ntsiab lus kub yog kev koom ua ke
Tam sim no, nrog rau lub ntiaj teb tseem ceeb ntawm kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov, kev tsim thiab siv cov PTFE cov ntsaws ruaj ruaj kuj yuav tsum tau xav txog kev tiv thaiv ib puag ncig. Kev txais yuav cov txheej txheem tsim ntsuab los txo cov pa roj carbon emissions thiab cov khoom pov tseg hauv cov txheej txheem tsim khoom yog ib qho kev xav tsis zoo rau kev txhim kho yav tom ntej. Nyob rau tib lub sijhawm, kev txhim kho ntawm cov khoom siv rov ua dua tshiab PTFE kom paub txog cov khoom siv rov ua dua tshiab kuj yog lub ntsiab lus kub ntawm kev txhawj xeeb hauv kev lag luam.
