FFKM Cov

Loj: Standard los yog non-standard

Xim: Dub, Dawb, Amber

Hardness: Feem ntau yog 75 ± 5 Ntug A, tuaj yeem ua tiav nrog ntau yam 60-90 durometer

Nyob rau hauv cov saw molecular ntawm FFKM, tag nrho cov hydrogen atoms ntawm carbon atoms yog hloov los ntawm fluorine atoms, uas yog ib tug roj hmab tsis muaj CH daim ntawv cog lus. Raws li thawj qhov chaw nyob rau hauv lub sij hawm lub rooj ntawm cov tshuaj, hydrogen yog heev active. Tom qab poob ntawm hydrogen, FFKM elastomer yuav ruaj khov heev. Cov khoom tshwj xeeb ntawm FFKM no pab tswj nws txoj kev sib khi thiab txhim kho kev nyab xeeb.

Vim nws qhov kev ua tau zoo ruaj khov, FFKM oring muaj cov tshuaj tiv thaiv zoo heev. Yog li ntawd nws yeej ib txwm siv nyob rau hauv lub sij hawm nrog nruj sealing yuav tsum tau, piv txwv li, thaum cov neeg muas zaub tau thov ntawm kub heev thiab complex xov xwm resistant.

Niaj hnub no, FFKM roj hmab foob ib feem tau siv dav hauv cov khoom siv semiconductor. Tsis tas li ntawd, nws kuj tau siv dav hauv aerospace, aviation, tshuaj lom neeg kev lag luam, roj av, nuclear zog thiab lwm yam kev lag luam uas nws ua haujlwm xav tau.
