Graphite Carbon Cruciblefeem ntau siv cov cuab yeej hauv cov hlau smelting, kev siv hauv chav kuaj, thiab lwm yam kev kho kub kub.Lawv muaj kev ruaj ntseg zoo heev thiab thermal conductivity, ua rau lawv nrov heev hauv cov ntawv thov no.Kab lus no yuav delve rau hauv yuav ua li casCarbon Graphite Crucible,los ntawm kev xaiv cov khoom siv raw mus rau cov txheej txheem tsim khoom ntawm cov khoom kawg.
Kauj Ruam 1: Xaiv cov khoom siv graphite tsim nyog
Thawj kauj ruam hauv kev ua graphite crucible yog xaiv cov khoom siv graphite tsim nyog.Graphite crucibles feem ntau yog ua los ntawm ntuj lossis dag graphite.Nov yog qee yam yuav tsum xav txog thaum xaiv cov khoom siv graphite:
1. Purity:
Lub purity ntawm graphite yog qhov tseem ceeb rau kev ua haujlwm ntawm lub crucible.High purity graphite crucibles tuaj yeem ua haujlwm ruaj khov ntawm qhov kub siab dua thiab tsis yooj yim cuam tshuam los ntawm cov tshuaj tiv thaiv.Yog li ntawd, kev tsim cov graphite crucibles feem ntau yuav tsum tau siv cov khoom siv graphite ntshiab heev.
2. Qauv:
Cov qauv ntawm Graphite Lined Crucible kuj yog qhov tseem ceeb.Fine grained graphite feem ntau yog siv los tsim khoom sab hauv ntawm crucibles, thaum coarser grained graphite yog siv los tsim lub plhaub sab nraud.Cov qauv no tuaj yeem muab qhov yuav tsum tau ua kom sov thiab thermal conductivity ntawm crucible.
3. Thermal conductivity:
Graphite yog cov khoom siv thermal conductive zoo heev, uas yog ib qho laj thawj vim li cas graphite crucibles tau siv dav hauv cov ntawv thov kub.Xaiv cov khoom siv graphite nrog cov thermal conductivity siab tuaj yeem txhim kho cov cua sov thiab cua txias ntawm lub crucible.
4. Corrosion kuj:
Nyob ntawm cov khoom ntawm cov khoom ua tiav, qee zaum yuav tsum xaiv cov khoom siv graphite nrog corrosion kuj.Piv txwv li, crucibles uas lis acidic los yog alkaline tshuaj feem ntau xav tau graphite nrog corrosion kuj.
Kauj Ruam 2: Npaj cov khoom siv graphite qub
Thaum xaiv cov khoom siv graphite tsim nyog, cov kauj ruam tom ntej yog los npaj cov khoom siv graphite qub rau hauv cov duab ntawm lub crucible.Cov txheej txheem no feem ntau suav nrog cov kauj ruam hauv qab no:
1. Crushing:
Cov khoom siv graphite qub feem ntau yog loj thiab yuav tsum tau crushed rau hauv cov khoom me me rau kev ua haujlwm tom ntej.Qhov no tuaj yeem ua tiav los ntawm kev siv tshuab crushing lossis tshuaj lom neeg txoj kev.
2. Kev sib xyaw thiab khi:
Graphite hais feem ntau yuav tsum tau muab sib xyaw nrog cov neeg ua haujlwm khi los tsim cov duab qub ntawm lub crucible.Binders tuaj yeem yog resins, adhesives, lossis lwm yam khoom siv los khi cov graphite kom muaj cov qauv ruaj khov hauv cov kauj ruam tom ntej.
3. Kev Tiv Thaiv:
Cov sib xyaw graphite thiab cov ntawv khi feem ntau yuav tsum tau nias rau hauv cov duab ntawm lub crucible nyob rau hauv qhov kub thiab txias.Cov kauj ruam no feem ntau ua tiav siv cov pwm tshwj xeeb crucible thiab xovxwm.
4. Qhuav:
Lub pressed crucible feem ntau yuav tsum tau qhuav kom tshem tawm cov dej noo thiab lwm cov kuab tshuaj los ntawm kev sib khi tus neeg sawv cev.Cov kauj ruam no tuaj yeem ua tiav ntawm qhov kub me me kom tsis txhob deformation lossis tawg ntawm crucible.
Kauj Ruam 3: Sintering thiab ua
Thaum tus thawj crucible tau npaj, sintering thiab kho cov txheej txheem yuav tsum tau ua kom paub tseeb tias lub crucible muaj qhov yuav tsum tau ua.Cov txheej txheem no feem ntau suav nrog cov kauj ruam hauv qab no:
1. Sintering:
Tus thawj Crucible feem ntau yuav tsum tau sintered ntawm qhov kub thiab txias kom ua rau cov graphite cov khoom sib txuas ntxiv nruj dua thiab txhim kho qhov ceev thiab lub zog ntawm lub crucible.Cov kauj ruam no feem ntau yog ua los ntawm nitrogen lossis inert cua kom tiv thaiv oxidation.
2. Kev kho deg:
Sab hauv thiab sab nrauv ntawm crucibles feem ntau xav tau kev kho tshwj xeeb los txhim kho lawv cov kev ua tau zoo.Cov chaw sab hauv yuav xav tau txheej txheej los yog txheej txheej kom muaj kev tiv thaiv corrosion los yog txhim kho cov cua sov.Qhov saum npoo sab nrauv yuav xav tau polishing lossis polishing kom tau ib qho chaw du.
3. Kev tshuaj xyuas thiab kev tswj xyuas zoo:
Kev tshuaj xyuas nruj thiab kev tswj xyuas zoo yuav tsum tau ua thaum lub sijhawm tsim khoom kom ntseeg tau tias lub crucible ua tau raws li cov kev cai tshwj xeeb.Qhov no suav nrog kev tshuaj xyuas qhov loj, qhov ntom ntom, thermal conductivity, thiab corrosion kuj ntawm lub crucible.
Kauj Ruam 4: Kev ua tiav kawg thiab cov khoom tiav
Thaum kawg, lub crucible npaj los ntawm cov kauj ruam saum toj no tuaj yeem raug ua tiav kom tau txais cov khoom tiav.Qhov no suav nrog kev txiav cov npoo ntawm lub crucible, xyuas kom meej qhov ntev, thiab ua qhov kev kuaj xyuas zaum kawg.Thaum lub crucible hla kev tswj tau zoo, nws tuaj yeem ntim thiab xa mus rau cov neeg siv khoom.
Nyob rau hauv luv luv, ua graphite crucibles yog ib tug complex txheej txheem uas yuav tsum tau meej craftsmanship thiab high-zoo graphite cov ntaub ntawv.Los ntawm kev xaiv cov ntaub ntawv tsim nyog, npaj cov khoom siv raw, sintering thiab ua, thiab ua raws li kev tswj hwm nruj, kev ua haujlwm siab graphite crucibles tuaj yeem tsim rau ntau yam kev siv kub.Kev tsim cov graphite crucibles yog ib feem tseem ceeb ntawm kev ua haujlwm ntawm graphite engineering, muab cov cuab yeej tseem ceeb rau ntau yam kev lag luam thiab kev tshawb fawb.
