FKM cov khoom siv roj hmab foob lub nplhaib yog lub nplhaib sib dhos ua los ntawm fluororubber (Fluorocarbon Rubber) lossis FKM cov khoom. FKM cov khoom siv yog cov khoom siv roj hmab ua haujlwm zoo nrog kev ua haujlwm zoo rau kev kub siab, tshuaj thiab roj.
cov khoom piav qhia
FKM cov khoom siv lub nplhaib roj hmab sealing yog lub voj voos zoo li lub foob, feem ntau yog ua los ntawm cov khoom siv FKM. Nws muaj elasticity zoo thiab compressibility thiab yog siv los sau thiab kaw qhov khoob hauv cov cuab yeej siv tshuab, cov kav dej lossis lwm cov ntsiab lus sib txuas los tiv thaiv cov kua dej, roj lossis impurities.
Cov yam ntxwv ntawm cov khoom
FKM khoom yog cov roj hmab hluavtaws nrog cov yam ntxwv hauv qab no:
Kev kub siab ua haujlwm: FKM cov ntaub ntawv muaj peev xwm tswj tau lawv cov elasticity thiab sealing zog nyob rau hauv qhov kub thiab txias ib puag ncig, feem ntau tiv taus kub txog li 200 degree.
Cov khoom siv tshuaj lom neeg: FKM cov ntaub ntawv muaj kev tiv thaiv zoo rau cov tshuaj feem ntau (xws li roj, cov kuab tshuaj, kua qaub, alkalis, thiab lwm yam) thiab tsim nyog rau ntau daim ntawv thov uas yuav tsum tau tiv thaiv kev tawm tsam tshuaj lom neeg.
Roj tsis kam: FKM cov ntaub ntawv muaj cov roj zoo thiab tuaj yeem tswj tau lawv cov kev ua tau zoo hauv kev sib cuag nrog cov roj nplua nyeem, roj thiab lwm yam kua roj av.
Huab cua tsis kam: cov khoom siv FKM tuaj yeem tiv thaiv cov teebmeem ntawm ultraviolet rays, oxygen, ozone thiab huab cua hloov. Nws muaj huab cua tsis zoo thiab tsim nyog rau qhov chaw sab nraum zoov.
Tsawg permeability: FKM cov khoom muaj qhov permeability tsawg, uas tuaj yeem tiv thaiv cov pa tawm ntawm cov pa thiab kua.
Nta
Sealing kev ua tau zoo: FKM cov khoom siv roj hmab foob lub nplhaib muaj kev sib khi zoo heev, tuaj yeem sau qhov sib txawv ntawm qhov sib txuas, thiab tiv thaiv kom tsis txhob muaj kua, roj lossis impurities.
Elasticity thiab compressibility: FKM daim duab plaub roj hmab sealing nplhaib muaj elasticity zoo thiab compressibility, thiab tuaj yeem hloov kho thiab kev vibrations ntawm qhov kev sib txuas kom ruaj ntseg sealing.
Lub neej ntev: cov khoom siv FKM muaj qhov ua tau zoo heev thiab tiv thaiv kev laus, thiab tuaj yeem tswj hwm nws qhov kev ua tau zoo thiab kev sib khi rau lub sijhawm ntev hauv qhov chaw hnyav.
Kev siv ntau yam: FKM daim duab plaub roj hmab sealing rings yog dav siv hauv tsheb, tshuab thiab khoom siv, tshuaj lom neeg kev lag luam, aerospace thiab lub zog thiab lwm yam kev lag luam kom ua tau raws li qhov yuav tsum tau ua rau sealing kev ua tau zoo thiab tshuaj tiv thaiv hauv ntau daim ntawv thov.
Kev txhim kho thiab kho
Kev teeb tsa ntawm FKM lub kaum sab xis roj hmab sealing nplhaib yuav tsum tau ua raws li cov txheej txheem kev teeb tsa thiab cov cai. Nws yog ib qho tsim nyog los xyuas kom meej tias lub nplhaib sealing raug ntsia kom raug ntawm qhov chaw sib txuas thiab saib xyuas kom tsis txhob muaj kev puas tsuaj lossis deformation. Tsis tu ncua tshuaj xyuas thiab tswj FKM lub nplhaib roj hmab foob kom paub meej tias nws qhov kev sib khi ua haujlwm thiab kev pabcuam lub neej.
