Cov ntsaws ruaj ruaj ua lub luag haujlwm tseem ceeb hauv ntau lub lag luam kev lag luam, txij li kev tsim khoom tsheb mus rau kev lag luam aerospace, tshuaj lom neeg thiab semiconductor, uas txhua tus xav tau cov kev daws teeb meem sealing zoo thiab txhim khu kev qha. Hauv qhov no,cov nplhaib graphite, ua ib yam khoom siv sealing tseem ceeb, maj mam qhia txog kev siv dav dav.
Lub nplhaib graphiteyog ib lub foob uas ua los ntawm cov khoom siv graphite uas muaj cov khoom ntshiab heev. Nws muaj cov yam ntxwv tshwj xeeb uas ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau kev sib khi. Ua ntej, cov nplhaib graphite muaj kev tiv taus kub zoo heev. Nws tseem ruaj khov hauv qhov chaw kub thiab muaj cov coefficient qis ntawm kev nthuav dav thermal, txo qhov kev pheej hmoo ntawm kev xau vim qhov kub hloov pauv. Qhov no ua rau cov nplhaib graphite zoo heev rau kev siv sib khi kub xws li cov hauv kev lag luam roj, tshuaj lom neeg thiab fais fab.
Qhov thib ob,cov nplhaib graphitemuaj kev ruaj khov tshuaj zoo. Nws tuaj yeem tiv taus kev yaig ntawm cov xov xwm corrosive, suav nrog cov kua qaub, alkalis, cov kuab tshuaj organic, thiab lwm yam. Qhov no ua raucov nplhaib graphiteIb yam khoom siv zoo tshaj plaws hauv kev lag luam tshuaj lom neeg thiab kev tsim khoom semiconductor. Hauv kev lag luam semiconductor, cov nplhaib graphite feem ntau siv los kaw cov pa roj huv siab kom tsis txhob muaj cov khoom tsis huv nkag thiab xyuas kom meej tias cov khoom siv muaj kev ntseeg siab thiab kev ua haujlwm zoo.
Tsis tas li ntawd,cov nplhaib graphitekuj muaj qhov elasticity zoo thiab sealing zog. Nws tuaj yeem hloov kho rau cov nplaim sealing ntawm ntau yam duab thiab qhov ntau thiab tsawg kom ntseeg tau tias muaj txiaj ntsig zoo sealing. Lub elasticity siab ntawm lub nplhaib graphite tso cai rau nws kom tiv taus kev hloov pauv siab thiab kev co thaum tswj hwm lub foob nruj. Qhov no ua raucov nplhaib graphitesiv dav rau kev kaw cov kua, cov pa roj thiab cov pa dej, xws li cov li qub, cov twj tso kua mis thiab cov kav dej.
Nrog rau kev txhim kho tas mus li ntawm kev siv tshuab hauv kev lag luam thiab kev txhim kho cov kev cai ua tau zoo ntawm cov foob, kev siv cov nplhaib graphite hauv kev lag luam foob tau dav dua. Piv txwv li, hauv kev tsim khoom semiconductor, qhov twg qhov kev thov rau qhov chaw huv si siab nce ntxiv, cov nplhaib graphite ua haujlwm ua cov kev daws teeb meem txhim khu kev qha uas tuaj yeem ua tau raws li cov kev cai nruj hauv cov txheej txheem semiconductor. Tsis tas li ntawd, nrog rau kev txhim kho sai ntawm cov lag luam xws li lub zog tshiab, tshuaj lom neeg, thiab aerospace, cov foob nrog cov kev xav tau siab rau kev tiv taus kub siab thiab kev tiv taus corrosion kuj yuav dhau los ua qhov kev thov tseem ceeb, thiab cov nplhaib graphite yuav ua lub luag haujlwm tseem ceeb hauv cov teb no.
Hauv kev xaus lus, graphite rings, ua ib yam khoom siv tseem ceeb rau kev sib khi, qhia txog kev siv dav hauv kev sib khi. Nws qhov kev tiv taus kub siab, kev ruaj khov tshuaj lom neeg thiab kev ywj pheej zoo ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv kub siab thiab cov khoom siv corrosive. Nrog rau kev loj hlob ntawm kev thov kev lag luam thiab kev nce qib ntawm thev naus laus zis, graphite rings yuav ua lub luag haujlwm tseem ceeb hauv kev tsim khoom semiconductor, kev lag luam tshuaj lom neeg, lub zog thiab lwm yam teb, thiab muab cov kev daws teeb meem sealing txhim khu kev qha rau kev siv hauv kev lag luam.
