Graphite crucible yog ib hom carbon raws li cov khoom siv uas muaj qhov zoo xws li cov cua kub tsis kam, siab thermal conductivity, qis coefficient ntawm expansion, thiab tus nqi qis. Yog li ntawd, nws yog dav siv nyob rau hauv cov ntaub ntawv npaj thiab ua. Txawm li cas los xij, xaiv qhov tsim nyog graphite crucible yuav tsum xav txog ntau yam los xyuas kom meej tias nws tuaj yeem ua tau raws li cov cai tshwj xeeb thaum siv. Kab lus no yuav qhia txog cov hauv paus ntsiab lus uas yuav tsum tau ua raws thaum xaiv graphite crucibles.
Khoom siv thiab purity
Ua ntej, nws yog ib qho tseem ceeb kom nkag siab txog cov khoom thiab purity ntawm graphite crucibles. High quality graphite crucibles feem ntau yog ua los ntawm high-purity graphite cov ntaub ntawv, nrog ib tug purity ntawm ntau tshaj 99%. Cov khoom siv high-purity graphite no tuaj yeem ua kom ntseeg tau tias lub crucible muaj cov thermal conductivity thiab kub tsis kam, thaum txo qhov cuam tshuam ntawm impurities ntawm qhov kev sim. Yog li ntawd, thaum xaiv graphite crucibles, cov khoom ua los ntawm high-purity graphite cov ntaub ntawv yuav tsum tau xaiv.
Tsim thiab Qauv
Qhov thib ob, kev tsim thiab qauv ntawm graphite crucible yuav tsum tau xav txog. Graphite crucibles ntawm cov duab sib txawv thiab cov qauv tsim yog tsim rau cov xwm txheej sib txawv. Piv txwv li, graphite crucible nrog lub hau tuaj yeem tswj tau qhov purity ntawm tus qauv thiab hnyav dua, thaum lub graphite crucible nrog lub stirrer yog tsim rau kev sim uas yuav tsum tau nplawm. Tsis tas li ntawd, cov phab ntsa tuab thiab cov qauv hauv qab ntawm lub crucible kuj yog qhov tseem ceeb rau kev txiav txim siab thaum xaiv. Lub thickness ntawm phab ntsa yuav cuam tshuam rau lub tshav kub tsis kam thiab thermal conductivity ntawm lub crucible, thaum lub hauv qab qauv yuav cuam tshuam lub load-bearing muaj peev xwm thiab kev pab cuam lub neej ntawm lub crucible.
Siv tau qhov kub thiab txias
Thaum xaiv cov graphite crucible, nws yog ib qho tseem ceeb kom nkag siab txog nws qhov ntsuas kub thiab siab ntau yam. Txawv graphite crucibles yog haum rau txawv kub thiab siab tej yam kev mob. Piv txwv li, kev sim nyob rau hauv qhov kub thiab txias tej yam kev mob yuav tsum tau siv tshwj xeeb tsim graphite crucibles. Yog li ntawd, nws yog ib qho tsim nyog los xaiv qhov tsim nyog crucible raws li qhov tseeb daim ntawv thov scenario los xyuas kom meej qhov tseeb thiab kev nyab xeeb ntawm qhov kev sim.
Nto zoo thiab kev kho mob
Nto zoo yog ib qho tseem ceeb hauv kev ntsuam xyuas qhov zoo ntawm graphite crucibles. Qhov saum npoo ntawm cov graphite crucibles zoo yuav tsum du, tiaj tus, tsis muaj qhov tsis xws luag xws li npuas thiab tawg. Tsis tas li ntawd, txhawm rau txhim kho lub neej kev pab cuam thiab kev ua haujlwm ntawm graphite crucibles, qee cov tuam txhab yuav ua qhov kev kho saum npoo ntawm graphite crucibles, xws li txheej, impregnation, thiab lwm yam. Thaum xaiv graphite crucible, nws yog ib qho tsim nyog los xaiv lub crucible nrog zoo nto. kev kho kom zoo thiab tsim nyog.
Manufacturers thiab cov kev pab cuam tom qab muag
Thaum kawg, nws yog ib qho tseem ceeb uas yuav tau xaiv lub chaw tsim khoom graphite crucible nrog lub npe nrov thiab kev pabcuam zoo tom qab muag. Cov npe nrov feem ntau muaj cov cuab yeej siv ntau lawm thiab kev tswj xyuas nruj, uas tuaj yeem ua kom zoo thiab ua haujlwm ntawm lawv cov khoom. Thiab kev pabcuam zoo tom qab muag tuaj yeem muab kev pabcuam kev pabcuam thiab kev pabcuam thaum lub sijhawm siv, ua kom muaj kev vam meej ntawm kev sim.
Hauv cov ntsiab lus, thaum xaiv cov graphite crucible, nws yuav tsum ua tib zoo xav txog ntau yam xws li cov khoom siv thiab purity, tsim thiab qauv, siv tau qhov kub thiab txias, qhov zoo thiab kev kho mob, nrog rau cov chaw tsim khoom thiab kev pab cuam tom qab muag. Los ntawm kev ntsuam xyuas cov yam tseem ceeb no thiab xaiv cov graphite crucibles uas tsim nyog, qhov tseeb ntawm cov txiaj ntsig kev sim thiab kev ua tiav ntawm cov txheej txheem kev sim tuaj yeem ua kom ntseeg tau, thaum txuas ntxiv lub neej kev pabcuam ntawm graphite crucibles thiab txhim kho kev sim ua haujlwm.
