Graphite carbon CrucibleFeem ntau siv cov cuab yeej hauv kev siv hlau, kuaj cov ntawv thov, thiab lwm cov txheej txheem kho kub siab. Lawv muaj kev kub siab heev-kub ruaj khov thiab thermal conductivity, ua rau lawv nrov nrov hauv cov ntawv thov no. Kab lus no yuav delve rau yuav ua li casCrium graphite,Los ntawm kev xaiv ntawm cov ntaub ntawv raw rau kev tsim cov txheej txheem ntawm cov khoom kawg.
Kauj ruam 1: Xaiv cov khoom siv graphite tsim nyog
Thawj kauj ruam hauv kev ua ib graphite crucible yog xaiv cov khoom siv graphite tsim nyog. Graphite crucles feem ntau yog ua los ntawm ntuj los yog graphite graphite. Nov yog qee yam los txiav txim siab thaum xaiv cov khoom siv graphite:
1. Purity:
Lub purity ntawm graphite yog qhov tseem ceeb rau kev ua tau zoo ntawm Crucible. Cov Purity High Graphite CruciBles tuaj yeem ua haujlwm stably ntawm ntau dua qhov kub thiab tsis yooj yim cuam tshuam los ntawm kev siv tshuaj lom neeg. Yog li ntawd, kev tsim khoom siab zoo graphite crucibles feem ntau yuav tsum siv cov ntaub ntawv ntshiab graphite.
2. Cov Qauv:
Cov qauv ntawm graphite lined crucible kuj tseem yog qhov tseem ceeb. Kev nplua cov graphite feem ntau yog siv los tsim lub sab hauv ntawm crucibles, thaum coarser graphite yog siv los tsim lub plhaub sab nraud. Cov qauv no tuaj yeem muab cov khoom siv hluav taws xob uas xav tau thiab thermal kev coj ua ntawm cov crucible.
3. Thermal conductivity:
Graphite yog ib qho zoo tshaj plaws thermal cov khoom siv, uas yog ib qho ntawm cov laj thawj yog vim li cas graphite crucibles tau siv dav hauv cov ntawv thov hnyav-. Xaiv graphite cov ntaub ntawv nrog cov thermal conductivity tuaj yeem txhim kho cov cua sov thiab cov nqi cua txias ntawm cov ntoo khaub zig.
4. Corrosion Kuj:
Nyob ntawm cov khoom ntawm cov khoom siv tau ua, nws qee zaum yuav tsum xaiv cov ntaub ntawv graphite nrog corrosion tsis kam. Piv txwv li, crucibles uas siv acidic los yog tshuaj tsw qab ib txwm xav tau graphite nrog corrosion tsis kam.
Kauj ruam 2: Npaj cov khoom siv graphite
Thaum xaiv cov khoom haum, cov kauj ruam tom ntej yog los npaj cov khoom siv graphite thawj rau hauv cov duab ntawm crucible. Tus txheej txheem no feem ntau suav nrog cov kauj ruam hauv qab no:
1. Kev sib tsoo:
Cov khoom siv graphite yog feem ntau loj thiab xav tau yuav tsum tau tsoo rau hauv cov khoom me me rau kev ua tiav. Qhov no tuaj yeem ua tiav los ntawm cov tshuab sib tsoo lossis cov qauv siv tshuaj.
2. Sib xyaw thiab khi:
Graphite hais feem ntau yuav tsum tau sib xyaw nrog cov neeg sawv cev los ua cov qauv ua ntej ntawm tus ntoo khaub zig. Binders tuaj yeem yog Resins, cov nplaum, lossis lwm yam ntaub ntawv siv rau cov qauv graphite kom tswj cov qauv ruaj khov hauv cov kauj ruam tom ntej.
3. Txhaum:
Cov graphed graphite thiab binder feem ntau yuav tsum tau nias rau hauv cov duab ntawm crucible hauv qab kub thiab siab. Cov kauj ruam no feem ntau yog ua tiav siv cov pob ntoo tshwj xeeb pwm thiab xovxwm.
4. Kom qhuav:
Cov nias tus ntoo khaub lig loj feem ntau yuav tsum tau qhuav kom tshem tawm cov dej noo thiab lwm yam kuab tshuaj los ntawm tus neeg sawv cev ntawm tus neeg sawv cev. Cov kauj ruam no tuaj yeem nqa tawm ntawm qhov kub thiab txias rau kev tiv thaiv deformation lossis tawg ntawm tus ntoo khaub zig.
Kauj ruam 3: Sintering thiab Kev Ua
Thaum tus thawj ntoo crucible yog npaj, sintering thiab cov txheej txheem kho yuav tsum tau nqa tawm kom ntseeg tau tias tus crucible muaj kev ua tau zoo. Tus txheej txheem no feem ntau suav nrog cov kauj ruam hauv qab no:
1. Sintering:
Cov thawj crucible feem ntau yuav tsum tau sintered ntawm qhov kub kom ua kom cov graphite hais kom nruj dua thiab txhim kho lub ntov thiab lub zog ntawm crucible. Cov kauj ruam no feem ntau nqa tawm hauv nitrogen lossis inert cua los tiv thaiv oxidation.
2. Nto Kho:
Sab hauv thiab sab nraud ntawm cov crucibles feem ntau yuav tsum tau kho mob tshwj xeeb los txhim kho lawv cov kev ua tau zoo. Sab hauv cov chaw yuav tas yuav txheej lossis txheej kom nce corrosion tsis kam lossis txhim kho kev kub. Cov nplaim sab nraud yuav xav tau polishing lossis polishing kom tau txais qhov chaw du.
3. Kev tshuaj xyuas thiab kev tswj xyuas zoo:
Kev kuaj nruj thiab kev tswj hwm nruj yuav tsum tau nqa tawm thaum lub sijhawm tsim kev tsim khoom los xyuas kom cov crucible raws li cov kev cai tshwj xeeb. Qhov no suav nrog kev kuaj qhov loj me, ntom ntom, thermal conductivity, thiab corrosion tsis kam ntawm crucible.
Kauj Ruam 4: Kev Ua Zaum Kawg thiab Cov Khoom tiav
Thaum kawg, npaj crucible npaj los ntawm cov theem saum toj no tuaj yeem raug ua tiav rau cov khoom tiav kom tau cov khoom tiav. Qhov no suav nrog cov npoo ntawm tus ntoo khaub lig, kom ntseeg tau qhov ntev, thiab ua cov tshev ua kom kawg. Thaum tus crucible dhau kev tswj hwm zoo, nws tuaj yeem ntim thiab faib rau cov neeg siv khoom.
Hauv ntej, ua graphite cruciles yog qhov txheej txheem nyuaj uas yuav tsum muaj cov khoom siv tes ua kom ncaj ncees thiab cov khoom siv zoo. Los ntawm xaiv cov ntaub ntawv tsim nyog, npaj cov ntaub ntawv raw, sintering thiab kev siv nruj me ntsis kev tswj hwm, ua tau zoo grucibles cov khoom siv yuav ua rau ntau yam kev siv kub ntau. Kev tsim qauv ntawm graphite crucibles yog qhov tseem ceeb ntawm kev ua teb graphite engineering, muab cov cuab yeej tsis tseem ceeb rau ntau yam kev lag luam thiab kev lag luam scientific.
