Qhov kwv yees hardness ntawm fluororubber gaskets yog dab tsi?

Lub hardness ntawm fluororubber gaskets feem ntau yog li ntawm 70 mus rau 90 Shore A, tab sis qhov tshwj xeeb hardness yuav txawv nyob ntawm seb cov fluororubber formulation, daim ntawv thov, thiab manufacturing txheej txheem.

 

Feem ntau, fluororubber gaskets siv nyob rau hauv siab - kub, siab - siab, thiab chemically corrosive ib puag ncig muaj kuj hardness, feem ntau yog nyob ib ncig ntawm 80 mus rau 90 Shore A. Qhov no yog vim hais tias hardness ntau dua muab sealing kev ua tau zoo dua thiab kub ua hauj, cia lawv tswj tau zoo sealing kev ua tau zoo thiab tiv thaiv tawm tawm txawm nyob rau hauv huab cua.

 

Txawm li cas los xij, hauv cov ntawv thov uas yuav tsum tau ua kom yooj yim dua ntawm lub foob, xws li cov neeg xav tau hloov mus rau qhov nyuaj sealing nto los yog xav tau qee qhov kev hloov ntawm elastic deformation, lub hardness ntawm fluororubber gaskets yuav txo mus rau 70 mus rau 80 Shore A. Tsawg hardness tso cai rau lub foob kom yooj yim hloov mus rau irregularities nyob rau hauv lub sealing nto, kev txhim kho kev ntseeg tau.

 

Tsis tas li ntawd, qhov nyuaj ntawm fluororubber gaskets kuj tuaj yeem cuam tshuam los ntawm hom thiab cov ntsiab lus ntawm cov muab tub lim. Ntxiv qhov tsim nyog ntawm cov muab tub lim tuaj yeem txhim kho qhov tawv thiab lub zog ntawm fluororubber, tab sis ntau cov muab tub lim tuaj yeem txo qhov elasticity thiab qaug zog tiv thaiv ntawm lub foob.
