PTFE txheej O nplhaib foob

PTFE Txheej O-Nplhaib Seals sawv cev rau qib siab -kev ua haujlwm sealing tov engineered rau ib puag ncig uas xav tau cov tshuaj tiv thaiv zoo tshaj, tsis muaj kev sib txhuam, thiab kev pab cuam lub neej ntev. Los ntawm kev sib txuas cov tub ntxhais elastomeric nrog cov txheej txheem nruj nruj PTFE txheej, cov ntsaws ruaj ruaj no xa cov kev ruaj khov thiab kev ruaj ntseg hla ntau yam kev lag luam, suav nrog kev ua tshuaj, tshuaj, khoom siv hluav taws xob, thiab cov tshuab hluav taws xob. PTFE-coated tsim txhim kho ob qho tib si kev ua neej nyob thiab kev ua haujlwm muaj kev ntseeg siab, ua rau lawv xaiv qhov kev xav tau kev sib khi ib puag ncig.

Lus Txhais thiab Qauv:

PTFE txheej O-ring seal yog ob lub- txheej sealing tivthaiv uas muaj ib tug elastomer core - xws li NBR, EPDM, FKM, los yog Silicone - tag nrho encapsulated los ntawm ib tug niaj hnub PTFE txheej. Lub plhaub PTFE no muab cov tshuaj zoo tshaj - tiv thaiv kev tiv thaiv thaum tuav lub compression thiab elasticity ntawm lub hauv paus elastomer. Kev sib xyaw ua ke txhim khu kev tiv thaiv rau cov tshuaj corrosive, kub kub, huab cua hloov pauv, thiab kev sib cuag cov neeg kho tshuab nruj.

PTFE txheej ua haujlwm li cas:

Cov txheej txheem yog siv los ntawm kev siv qhov tseeb -engineered bonding thiab molding txheej txheem los xyuas kom meej seamless kev pab them nqi thiab zoo adhesion. Cov txheej txheej feem ntau yog li ntawm 0.05mm txog 0.2mm, muab:

• Superior Chemical Shielding:Tiv thaiv corrosive media los ntawm degrading lub elastomer core.
• Kev sib txhuam qis:Qhov tseem ceeb txo qhov hnav thiab kev teeb tsa lub zog.
• Siab Thermal Stability:Ua kom muaj kev ncaj ncees nyob rau hauv ob qho tib si cryogenic thiab siab - qhov kub thiab txias.
• Tsis yog -stick Performance:Txo kev tsim- ntawm cov khoom paug thiab ua kom yooj yim ntxuav.

Tsis sib haum chemical Resistance:

PTFE yog inert rau ze li ntawm tag nrho cov tshuaj, ua rau cov O-rings zoo tagnrho rau kev sib cuag nrog cov tshuaj phem:

• Acids: sulfuric, nitric, hydrochloric, thiab lwm yam
• Alkalis thiab caustic media
• Organic kuab tshuaj thiab hydrocarbons
• Oxidizers, tshuaj dawb, thiab ozone
• Roj, roj, thiab lubricants
• Siab - purity chemical intermediates

Kev khiav dej num dav dav:

Cov txheej PTFE tseem nyob ruaj khov thiab tsis muaj tshuaj lom neeg los ntawm qhov kub thiab txias li ntawm -200℃txog rau +260 degree, nyob ntawm qhov xaiv elastomer. Qhov no zoo heev tshaj qhov ntsuas kub ntawm cov qauv roj hmab uas tsis muaj coated O-rings.

Kev sib txhuam qis & Lub neej ua haujlwm ntev:

Lub PTFE nto txo ​​cov neeg kho tshuab kev ntxhov siab thiab kev puas tsuaj, tshwj xeeb tshaj yog nyob rau hauv kev siv dynamic:

• Txo kev sib txhuam thaum zawv zawg thiab rov ua haujlwm
• Txo txoj kev pheej hmoo ntawm kev tawg ntawm qhov chaw thaum sib dhos
• Txo cov cua sov tsim los ntawm kev sib cuag dynamic
• Minimized stick-slip thiab vibration-txog hnav

Hygienic thiab Tsis yog -Tag Nto:

Lub PTFE du tiav tiv thaiv particle adhesion thiab cov kab mob sib sau ua ke, ua rau cov ntsaws ruaj ruaj haum rau kev tu cev.

• Tsis muaj media absorption
• Cov kab mob tsawg kawg nkaus
• Ib qho yooj yim ntxuav thiab sterilization
• Tsis yog-staining thiab tsis-reactive

Tus nqi ua haujlwm dhau sijhawm:

PTFE coated O-rings txo kev hloov zaus thiab kev saib xyuas xav tau:

• Lub neej ua haujlwm ntev dua
• Superior sealing kev ntseeg tau
• Txo downtime
• Tau tshaj tus qauv O-ring groove designs
