RPTFE (hloov polytetrafluoroethylene) cov ntsaws ruaj ruaj hauv cov khoom lag luam vim lawv cov tshuaj txhuam tsis zoo, thiab kub siab (-200 {1} degree). Mastering kom tsim nyog cov tswv yim kom tsim nyog tuaj yeem txuas ntxiv lawv kev pabcuam lub neej thiab txhim kho kev ua haujlwm.
Ua ntej -} Kev npaj nruab yog qhov tseem ceeb heev. Txawm hais tias RTTFE yog hloov tau yooj yim, nws yog qhov txaus ntshai rau cov dej ntws txias. Ua ntej kev teeb tsa, ntxuav cov suab sib khi nrog cov cawv tsis muaj cawv kom tsis txhob muaj paug los ntawm cov roj paug los ntawm cov roj thiab cov khoom noj. Rau dynamic ntim xws li o - rings, maj mam motenen saum npoo nrog cov khoom sib dhos silicone lossis tiv thaiv kom tsis txhob ua kua muag thaum lub sijhawm teeb tsa. Xyuam xim kom tsis txhob khawb cov khoom sib khi nrog cov cuab yeej ntse; Siv cov cuab yeej teeb tsa siab.
Kev tswj hwm kev tswj hwm ntawm tus nqi compression ncaj qha cuam tshuam kev cuam tshuam ncaj qha cuam tshuam kev ua tau zoo. Rau cov ntsaws ruaj ruaj, kev pom zoo compression yog 15% {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Hauv cov ntawv thov siab-siab, ntau txheej txheej ntawm cov gaskets tuaj yeem muab pawg, tab sis kom cov khoom thauj khoom uas tsis muaj peev xwm faib tawm ntawm cov txheej txheej. Rau cov flange sib txuas, nws raug pom zoo kom siv lub nplhaib hlau hluav taws xob ntau lub nplhaib los them rau kev so kom tshwm sim los ntawm cov dej txias ntev.
Kev saib xyuas kev ceev faj suav nrog kev soj ntsuam cov chaw sib dhos ua ntu zus rau cov kab nrib pleb lossis tawv ncauj (cov cim ntawm kev laus). Hloov lub sij hawm yuav tsum tau ua kom luv yog tias hu rau nruab nrab muaj cov oxidizers muaj zog (xws li muaj cov roj sulfuric). Muab cia kom deb ntawm lub teeb, noo noo, thiab cov kuab tshuaj organic, thiab ua kom cov huab cua sov hauv qab 50 degree.
Cov ntaub ntawv hloov thiab hloov RPTfe siv tau rau kev ua haujlwm tshwj xeeb: piv txwv li cov fiber ntau dua, cov hmoov txhuas tuaj yeem muab ntxiv rau txhim kho lub zog compressive. Kev xaiv kom tsim nyog thiab ua haujlwm kom raug kom paub tseeb tias RTTFE ntsaws ruaj ruaj uas tau ua zoo xws li kev lag luam thiab cov semiconductor kev lag luam.
