Graphite shreglesYog siv dav hauv ntau daim ntawv thov, thiab nws yog qhov tseem ceeb los ua kev tshuaj xyuas meej thiab ua tib zoo xaiv cov ntaub ntawv tsim nyog. Nov yog qee cov lus qhia rau kev kuaj xyuas thiab xaivGraphite shregles:
Ua ntej siv tshuaj xyuas: ua ntej siv covGraphite crucible, tshuaj xyuas cov kab nrib pleb thiab kev puas tsuaj. Nco ntsoov tias tsis muaj qhov ua kom pom cov kab nrib pleb, nws yog qhov tsim nyog yuav tsum tau ua kom sov cov crucible rau qhov kub tshaj 600 ° C kom ua kom huv si kom qhuav.
Kev npaj ib puag ncig ib puag ncig uas tsis muaj cov dej ntim rau hauv lub cub tawg lossis qhov chaw uas cov crucible yuav muab tso. Tsis tas li, khaws cov khoom tsis txheeb ze ntawm ib puag ncig ntawm cov graphite crucible.
Khoom siv tau: Siv ceev faj thaum tuav cov khoom cub. Xyuas kom meej tias cov ntaub ntawv tsis tawg thiab tau muaj kev ua si thiab qhuav. Thaum ntxiv cov ntaub ntawv rau cov graphite crucible, ua nws maj mam thiab tsis tu ncua.
Nws yog qhov tseem ceeb kom ua raws li cov lus qhia soj ntsuam no kom tiv thaiv cov kev phom sij thiab tawg thaum siv cov cruci-cruciles.
Graphite crucles yog feem ntau siv rau cov khoom siv cua sov. Lawv muaj ntau qhov ntau thiab tsawg, tso cai rau kev xaiv ntawm Crucible uas tsim nyog raws li cov nyiaj, thiab thermal expansion ntawm cov ntaub ntawv raug muab rhaub. Nws yog qhov tseem ceeb rau kev zam cov crucible nrog cov cua sov, raws li nws tuaj yeem ua rau muaj kev sib tsoo thaum lub neej muaj sia. Tsis tas li ntawd, thaum Crucible yog rhuab rau kev kub siab, feem ntau yog ib puag ncig 400 ° C, nws yog qhov kov nws nrog rau txhais tes zoo li nws tuaj yeem ua rau kub hnyiab.
Kev xaiv cov khoom siv rau Graphite criBles koom nrog kev txiav txim siab cov hauv qab no:
Repractoriness: Graphite crucibles yuav tsum tau siab dua los tiv thaiv huab kub heev. Yog li ntawd, nws yog qhov tseem ceeb los ntsuas qhov hluav taws kub tiv thaiv cov khoom tawg crucible kom ntseeg tau tias kev siv zoo nkauj.
Tshuaj lom neeg ruaj khov: Graphite crucibles feem ntau yog siv hauv cov txheej txheem corrosive. Li no, cov tshuaj ruaj khov ntawm cov khoom crucible yog qhov tseem ceeb rau kev xeb corrosion.
Cov khoom siv tawv tawv thiab tawv: lub hardness thiab tawv ntawm cov khoom crucable crucible crucible yuav tsum tau txiav txim siab los tiv thaiv briittle fracture thaum siv.
Los ntawm adhering rau cov khoom siv xaiv los saum toj no, peb tuaj yeem ua kom cov kev ua tau zoo ntawm graphite crucples.
Peb cia siab tias cov txheej txheem kev tshuaj xyuas no thiab cov txheej txheem cov txheej txheem muaj txiaj ntsig zoo rau kev tsim khoom thiab siv cov txheej txheem graphite, tso cai rau kev nyab xeeb thiab kev ua haujlwm zoo.
