Aegis, Aflas, Butyl, Fluorosilicone, Hypalon lossis ib qho kev sib xyaw uas koj daim ntawv thov tshwj xeeb yuav xav tau.Coated thiab Encapsulated O-Rings yog lwm txoj kev xaiv:
- Coated los yog Encapsulated - Coated O-Rings yog PTFE coated, nrog rau txheej adhering rau O-Ring (feem ntau Silicone los yog Viton los yog NBR ).Encapsulated O-Rings yog O-Ring (feem ntau Silicone lossis Viton) npog nrog PTFE raj.PTFE txheej ntawm O-Rings yog qhov zoo tshaj plaws-kev sib txhuam txheej uas ua haujlwm yooj yim yog qhov tseem ceeb.Lub encapsulated O-Ring coj zoo li cov kua nplaum uas muaj kuab heev, txhua qhov siab ntawm lub foob raug xa mus rau txhua qhov kev qhia.Coated O-Rings muaj nyob rau hauv ntau yam xim.
- Cov khoom sib xyaw tshwj xeeb - Yog tias koj muaj qhov yuav tsum tau ua rau ib qho kev sib xyaw tshwj xeeb uas tsis yog tus qauv kev lag luam ib txwm muaj, peb tuaj yeem ua haujlwm nrog cov tuam txhab tsim khoom tshwj xeeb kom tau raws li koj cov kev xav tau.
- Mil-Spec, Mil-Std lossis Milspecs yog lub tebchaws United States defese tus qauv siv los ua kom tiav cov hom phiaj kev cai los ntawm US Department of Defense.Rockets Seals tuaj yeem muab Mil-Spec los ntawm peb lub network loj ntawm cov khoom muaj npe nrov.
- FDA cov khoom noj khoom haus qib, cov npe txawv teb chaws, USP, KTW, DVGW, BAM, WRAS (WRC), NSF, Underwriters Laboratories (UL), Aerospace (AMS) thiab Mil-Spec - Rocket muaj kev paub txog kev ua tau raws li koj cov kev xav tau thoob plaws txhua yam kev lag luam.
koj tuaj yeem xaiv cov xim nram qab no lossis lwm yam xim ntxiv.
Paub zoo dua los ntawm lub npe Teflon, polytetrafluoroethylene (PTFE) muab ib qho chaw tsis zoo rau cookware, ntsia thawv polish, hairstyling cov cuab yeej, ntaub / ntaub pua plag kho, thiab windshield wiper hniav.Txawm li cas los xij, cov tuam txhab tau pom cov txiaj ntsig zoo los ntawm kev siv PTFE ua ib txoj hauv kev los tsim cov O-rings zoo.O-ringsua siv PTFE muab superior thermal thiab tshuaj rwb thaiv tsev, thiab lawv muaj peev xwm tiv taus kev sib txhuam thiab dej thiab.
PTFE VERSUS TEFLON
Txawm hais tias lawv sib txawv hauv kev tsim khoom lag luam, PTFE thiab Teflon sib koom ua ke hauv keeb kwm thiab cov khoom.
PTFE
PTFE yog ib tug hluavtaws polymer muab los ntawm cov tshuaj sib txuas ntawm carbon thiab fluorine, noj kom zoo dua ntawm dawb radicals 'xav mus polymerize nrog tetrafluoroethylene.Cov ntaub ntawv no tau tshwm sim thaum xyoo 1938, thaum DuPont chemist Roy J. Plunkett sim tsim ib hom tshiab ntawm cov tub yees, thiab muab cov ntaub ntawv no sib xyaw ua ke yam tsis paub txog cov tshuaj tiv thaiv uas nws yuav ua rau.
TEFLON
Kinetic Chemicals, lub tuam txhab kev koom tes ntawm DuPont thiab General Motors, luam tawm PTFE raws li lub npe Teflon nyob rau hauv 1945. Hauv essence, Teflon yog PTFE.Txawm li cas los xij, PTFE kuj muaj nyob rau hauv ntau yam ntawm lwm lub npe, xws li:
- Daikin-Polyflon
- Fluon
- Dyneon
PROPERTIES
Ntau yam khoom txawv ntawm PTFE los ntawm lwm yam khoom, suav nrog:
- Tsis tshua muaj kev sib txhuam coefficient: PTFE muaj qhov thib peb qis tshaj kev sib txhuam coefficient ntawm txhua yam khoom paub rau txiv neej, txhais tau tias nws yog tiag tiag
- Kev ua haujlwm ntawm qhov kub thiab txias: Rated ntawm 600 K, PTFE melts ntawm 327ºC lossis 620ºF, thiab nws kuj ua haujlwm zoo ntawm qhov kub thiab txias li −268ºC lossis −450ºF.
- Resistant dej: Cov hlaws dej nyob rau saum npoo ntawm PTFE, txhais tau hais tias qhov chaw kho nrog cov khoom no tiv thaiv oxidation.
- Nonreactive: PTFE tsis hnov mob nrog rau feem ntau ntawm cov khoom corrosive, ua rau nws zoo tagnrho rau siv hauv cov kav dej, li qub, cov ntsaws ruaj ruaj, thiab O-rings.
PTFE'S HIGH TEMPERATURE Range
Qhov kub ntau (-1,000F txog +4,000F), nonreactivity, dej tsis kam, thiab tsis tshua muaj kev sib txhuam ntawm PTFE ua rau nws yog ib qho khoom siv zoo tshaj plaws los tsim O-rings rau siv ntau yam kev siv.Cov khoom no ua rau PTFE O-rings yog qhov kev xaiv zoo tshaj plaws rau kev siv huab cua tiv thaiv nrog rau kev siv hluav taws xob thiab thermal rwb thaiv tsev.
Vim lawv qhov ntom ntom,PTFE O-ringstsis yog "melt-formed" - hloov, lawv tau compressed thiab sintered los muab cov duab tsim nyog.
TEFLON / PTFE Foob
O-ringsua los ntawm PTFE yog tam sim no nyob rau hauv ib tug ntau yam ntawm industrial daim ntaub ntawv uas yuav tsum tau cov ntsaws ruaj ruaj uas muaj peev xwm sawv kev nyuaj siab.PTFE O-rings tshwm sim nyob rau hauv ntau daim ntawv thov uas raug rau cov nram qab no cov yam ntxwv:
| Cov ntawv thov saum toj kawg nkaus | Mechanical Weaknesses |
