Automobile Mailbox FKM O-ring Description
Tsheb mailbox FKM O-ring yog cov khoom siv fluororubber sealing siv rau kev sib khi lub tsheb roj tso tsheb hlau luam lossis cov kua tso tsheb hlau luam. Nws feem ntau yog ua los ntawm cov khoom siv FKM, uas yog roj-resistant, tshuaj-resistant thiab kub-resistant, thiab yog haum rau lub tsheb mailbox sealing yuav tsum.
Lub thawv ntawv lub tsheb yog lub thawv uas siv los khaws roj lossis lwm yam kua thiab ua lub luag haujlwm tseem ceeb hauv lub tsheb roj. FKM O-rings xav tias lub luag haujlwm ntawm kev sib khi hauv lub thawv xa ntawv tsheb kom ntseeg tau tias roj lossis kua tsis xau thiab tiv thaiv kev sib kis lossis kev puas tsuaj los ntawm ib puag ncig sab nraud.

Qib ntawm FKM O-rings feem ntau siv nyob rau hauv tsheb xa ntawv tuaj yeem sib txawv raws li cov kev xav tau tshwj xeeb thiab cov chaw tsim khoom tsheb tshwj xeeb. Feem ntau hais lus, cov qib FKM O-ring feem ntau yog 70 Shore A lossis 75 Shore A hais txog qhov tawv thiab muaj roj ntau dua, tshuaj lom neeg thiab kub tsis kam.
FKM 70 thiab FKM 75 yog hom FKM cov khoom siv hardness feem ntau siv hauv tsheb mailbox sealing daim ntaub ntawv. Lawv muaj cov roj ua haujlwm zoo thiab tuaj yeem tiv taus corrosion los ntawm cov roj tsheb thiab cov roj nplua nyeem. Nyob rau tib lub sijhawm, FKM cov ntaub ntawv tseem muaj cov tshuaj tiv thaiv zoo heev thiab tuaj yeem tiv thaiv kev yaig ntawm cov tshuaj xws li cov kuab tshuaj, acids, alkalis, thiab oxidants. Tsis tas li ntawd, FKM cov ntaub ntawv kuj muaj qhov kub thiab txias thiab tuaj yeem tswj tau lawv lub cev thiab cov khoom sib khi hauv lub tsheb ua haujlwm kub.
