PTFE los yog polymer O-Rings muaj kev tiv thaiv zoo rau yuav luag txhua yam tshuaj xws li acids, bases, roj, chav ......
PTFE O-Rings Taw Qhia
Lub impermeability ntawm PTFE rau zoo tag nrho cov gases thiab kua nruab nrab ntawm -320 ° F thiab + 450 ° F yog ib qho ntawm nws cov khoom txawv tshaj plaws thaum siv hauv O-Ring sealing tshuab.Kev ncaj ncees ntawm PTFE yuav degraded tsuas yog thaum los rau hauv kev sib cuag nrog molten alkaline hlau thiab ib co halogenated tebchaw.PTFE yog cov khoom ntawm kev xaiv los xyuas kom meej lub compatibility ntawm O-Ring foob nrog ib tug kaw nruab nrab los yog rau sealing tshaj ib tug dav kub ntau yam.
Tsim Cov Lus Qhia rau PTFE O-Rings
Txheem roj hmab O-Ring xyaum xws li Ib MIL-G-5514 feem ntau pom zoo nyob rau hauv cov ntaub ntawv ntawm compressive-type installations rau dynamic daim ntaub ntawv.TG O-Rings kuj tseem siv tau rau cov ntawv thov tshwj xeeb.Txij li thaum lub cev sib txawv ntawm PTFE thiab elastomeric tebchaw yog siab heev, cov hauv qab no tsim thiab installation txoj kev yuav xa qhov zoo tshaj plaws tau sealing tshwm sim nyob rau hauv cov nqe lus ntawm kev ua tau zoo thiab foob lub neej:
- Tsis zoo li roj hmab O-Rings, PTFE O-Rings tsis muaj kev ua haujlwm tsis zoo, yog li nws muaj peev xwm txo qis caj pas.
- PTFE O-Rings tsis muaj qhov ua tau raws li cov roj hmab O-Rings;yog li ntawd nws yog ib qho tsim nyog yuav tsum tau txo qis qhov ntu ntu ntu sib txuas nrog cov ntawv teev tseg rau roj hmab kom yooj yim sib dhos.
Cov Lus Qhia Txhim Kho rau Polymer O-Rings
Tiv thaiv PTFE O-Rings los ntawm kev tau txais nicked lossis gouged thaum lub sijhawm teeb tsa yog qhov tseem ceeb.Gouging tuaj yeem tshwm sim thaum ncab O-Rings hla lub xub pwg ntse lossis xov.Nws tuaj yeem zam tau los ntawm kev thauj cov nplhaib hla qhov chaw ntse los ntawm kev siv cov cuab yeej los yog muab cov ces kaum so lossis radii.Nruab nrab ncab, yog tias ua tau qis dua 10%, raug pom zoo thaum lub sijhawm O-Ring installation.Kev siv cov roj kub los yog dej da dej ua kom yooj yim dua li qhov xav tau.Tsim cov kev hloov pauv lossis cov txheej txheem tshwj xeeb tej zaum yuav xav tau rau cov xwm txheej stretch ntau dua 20%.
PTFE yog nquag nkag mus zoo li tag nrho cov thermoplastics.Cov yam ntxwv no yuav tsum tau hais txog txhawm rau kom tsis txhob poob ntawm lub sealing load.Nws muaj peev xwm ameliorate qhov cuam tshuam ntawm cov dej txias los ntawm kev hloov kho qhov ntev raws li pom zoo hauv cov ntxhuav.
PTFE O-Rings tuaj yeem tsim los ntawm ntau lub tebchaw xws li graphite-filled PTFE, bronze thiab iav.Feem ntau, cov kev xav tau tuaj yeem ua tau raws li PTFE tsis ua tiav.
Qhov zoo ntawm PTFE O-Rings
- O-Rings yog ib qho kev daws teeb meem zoo tshaj plaws rau cov tshuab qis qis
- Universal tshuaj compatibility ntawm PTFE
- Kev kub ntau ntawm -320 ° F thiab + 500 ° F
- Fast pricing thiab tam sim tig ib ncig
- Kev xaiv dav ntawm O-Rings ntawm 0.110 "thiab ~ 40";tshwj xeeb qhov loj me yog muaj raws li qhov kev thov
- Nqus mus rau high-pressure, thaum siv nrog rau lub nplhaib haum rov qab
