Txoj kev tsim cov pas nrig cua sov graphite hauv lub tshuab cua sov

Lub tshuab nqus tsevgraphite pas nrigtseem hu ua lub tshuab cua sov graphite cua sov pas nrig. Thaum ub, tib neeg tig graphite mus ua carbon, yog li nws hu uacov pas nrig carbonCov khoom siv raw ntawm graphite carbon pas nrig yog graphite, uas hu ua nplaum molding. Nws tuaj yeem ua rau cov khoom graphite ntawm ntau yam duab, suav nrog graphite puag ncig pas nrig. Vim yog cov yam ntxwv ntawm graphite, nws muaj cov yam ntxwv zoo tshwj xeeb xws likev coj hluav taws xob, lubrication, kev ua haujlwm kub siabthiab lwm yam. Yog li ntawd, cov pas nrig graphite carbon kuj muajkev coj ua zoo heev, kev xa cua sov, kev ua kom lubrication,kev ua haujlwm kub siabthiab lwm yam khoom. Lub xeev yav tom ntej yog tias cov khoom ntawm graphite tsis hloov pauv. Yog li ntawd, kev tsim khoom thiab kev muab khoom ntawm graphite rods yog txawv, thiab cov yam ntxwv ua haujlwm ntawm graphite rods tsim tawm yuav txawv. Yog li yuav ua li cas thiaj paub qhov txawv? Cov khoom graphite uas tsim tau yog ua los ntawm graphite hmoov thiab nplaum ncaj qha, lossis ua ntej ua rau cov khoom siv loj, uas tau ua los ntawm lub tshuab raws li daim duab kos lossis cov duab khoom.
Muaj qhov sib txawv thiab cov yam ntxwv ntawm cov pas nrig graphite uas ua los ntawm thawj txoj kev thiab cov pas nrig graphite uas ua los ntawm txoj kev thib ob. Vim yog qhov siab tsis txaus thaum lub sijhawm extrusion, qhovextruded graphite pas nrignrog cov hmoov graphite thiab cov nplaum yuav mos heev, nrog qhov ceev tsis zoo thiab cua nruj loj (qhov loj). Cov hmoov av yuav poob tawm hauv lub xeev ntuj, thiab nws yuav tawg thaum ntub nrog cawv. Tib lub sijhawm, vim muaj ntau cov nplaum, qhov conductivity, cua sov conduction thiab lubrication ntawm graphite pas nrig yuav raug txo qis heev, Qhov laj thawj yooj yim heev. Graphite yog cov khoom siv conductive thiab cov nplaum yog ib qhocov khoom siv rwb thaiv tsev, uas yuav txo qhov conductivity ntawm graphite pas nrig. Lub npe txheem rau cov graphite carbon pas nrig no yog carbon arc cua gouging carbon pas nrig. Nws yog siv rau kev txiav hauv foundry. Qhov chaw yuav tsum tau plated nrog ib txheej ntawm tooj liab kom tiv thaiv cov dej noo thiab conduct hluav taws xob. Yog li ntawd, hom carbon pas nrig no kuj muaj qhov feature uas lub cheeb tsam yuav tsawg dua 0.1-0.2 hli cim, vim tias qhov chaw yuav tsuas yog mus txog lub cheeb tsam cim thaum nws yog plated nrog 10% hlau.
Txawm hais tias txoj kev thib ob kuj yog ua los ntawm hmoov graphite thiab nplaum, muaj kev hais txog nws cov txheej txheem. Ua ntej, hmoov graphite thiab nplaum yog siv los ua cov khoom lojcov ntaub ntawv graphitenyob rau hauv kev kub siab, thiab tom qab ntawdua kom cev xeeb tublos ntawm kev ci kub siab (ua kom qhuav thiab ua kom cov nplaum tsis lo). Ua li no, yuav luag tsis muaj cov nplaum hauv graphite tom qab rov ua kom cov nplaum rov qab. Cov txheej txheem ci impregnation no yog qhov tseem ceeb heev. Cov graphite txo qis tom qab ci impregnation muaj cov yam ntxwv ntawm graphite nws tus kheej thiab muaj tag nrho cov haujlwm thiab cov yam ntxwv ntawm graphite. Vim tias cov graphite no muaj kev huv siab dua, nws tseem hu uagraphite purity siab, thiab cov pas nrig graphite ua los kuj hu ua cov pas nrig graphite siab-purity.
