Graphite crucibleyog cov cuab yeej siv dav hauv cov hlau smelting thiab kev siv kub siab-. Lawv tau siv los ua cov hlau kub lossis lwm cov tshuaj rau cov kub kom yaj, ua rau muaj kev kub ntxhov, thiab lwm yam kev kub kub. Txawm li cas los xij, sijhawm dhau sijhawm, ntau yam impurities thiab cov seem tso rau saum npoo ntawm Crucible, cuam tshuam nws cov kev ua tau zoo. Yog li ntawd, nkag siab txog kev ntxuav kom huvGraphite shreglesyog qhov tseem ceeb rau kev ncua lawv lub neej. Hauv tsab xov xwm no, peb yuav qhia cov kauj ruam tseem ceeb rau kev ntxuav graphite crucibles.
Vim li cas peb yuav tsum tau ntxuav cov graphite crucible?
Graphite shreglesKev khiav hauj lwm kub yog nquag mus rau adsorbing thiab nqus tau ntau yam tsis zoo, oxides, thiab lwm yam tsis sib xws. Cov impurities no tuaj yeem ua rau paug rau saum npoo ntawm Crucible, txo nws cov thermal conductivity thiab thermal conductivity. Tsis tas li ntawd, kev tsim tawm kuj tseem tuaj yeem ua rau muaj kev ntxhov siab kub hauv lub crucible hauv tus ntoo khaub zig, thaum kawg ua rau tawg lossis ua kom puas.
Yog li ntawd, kev tu cev tsis tu ncua ntawm graphite crucibles yog cov kauj ruam tseem ceeb hauv kev tswj lawv cov kev ua tau zoo thiab nthuav lawv lub neej.
Cov kauj ruam tseem ceeb rau kev ntxuav Graphite crucibles
Hauv qab no yog cov kauj ruam tseem ceeb kom ntxuav graphite crucibles:
1. Kev Ntsuam Xyuas Kev Nyab Xeeb:
Ua ntej ntxuav cov graphite crucible, thov xyuas kom haum kev ntsuas kev nyab xeeb uas tsim nyog kev nyab xeeb. Qhov no suav nrog looj hnab looj tes sov thiab goggles kom tiv thaiv kev raug mob.
2. Cua daj crucible:
Ua ntej ntxuav, xyuas kom meej tias cov graphite crucible tau txias txias. Ntxuav thaum kub siab yuav ua rau kub siab thiab txias thiab puas tsuaj rau tus ntoo khaub zig.
3. Tshem tawm cov seem:
Siv hlau scraper lossis pliers kom maj mam tshem tawm cov seem ntawm saum npoo ntawm crucible. Thov khiav haujlwm nrog kev ceev faj kom tsis txhob khawb tus ntoo khaublig.
4. Tshuaj Tu:
Rau qee qhov nyuaj tshem cov av thiab cov seem, tshuaj ntxuav tshuaj lom neeg tuaj yeem siv. Xaiv cov neeg sawv cev tu kom tu cov tawv ntoo, xws li sodium hydroxide lossis potassium hydrocide daws, thiab ua raws cov lus qhia rau kev siv cov neeg sawv cev tu. Feem ntau, kev tu tus neeg saib xyuas yog yaj hauv dej sov thiab crucible yog tsau rau hauv nws kom mos thiab tshem tawm cov av. Tom qab ua tiav, yaug cov crucible kom huv si nrog dej huv los tiv thaiv cov tshuaj seem ntawm seem ntawm qhov chaw.
5. Ua kom qhuav Crucible:
Tom qab tu thiab yaug, tso cov crucible nyob rau hauv qhov cub tsawg-huab cua lossis huab cua qhuav kom ntseeg tau tias nws qhuav kiag li. Zam kev siv cov cua sov ntse lossis txias cov txheej txheem los tiv thaiv kev ntxhov siab thermal.
6. Txheeb xyuas saum npoo ntawm tus ntoo khaub zig:
Tom qab tu thiab ziab, ua tib zoo tshuaj xyuas qhov saum npoo ntawm crucible kom ntseeg tau tias tsis muaj qhov seem lossis kev puas tsuaj. Yog tias tsim nyog, tu ntxiv lossis kho kom tau tuaj yeem nqa tawm.
Ceev faj thiab cov lus qhia
Thaum ntxuav graphite crucibles, tseem muaj qee qhov kev ceev faj thiab cov lus qhia:
Zam txhob siv cov acidic ntxuav cov neeg sawv cev thaum lawv yuav ua puas cov ntaub ntawv graphite.
Tsis txhob siv cov txhuam txhuam hlau lossis cov hlau txhuam los ntxuav cov crucible raws li lawv tuaj yeem khawb saum npoo.
Thaum siv cov khoom siv tshuaj tu cev, thov cov cuab yeej tiv thaiv thiab xyuas kom meej tias kev ua haujlwm yog nqa tawm hauv qhov chaw muaj cua zoo.
Nquag ntxuav cov crucible kom tiv thaiv cov plua plav thiab cov seem los ntawm kev sau rau qib uas nyuaj rau lis.
Raws li cov kev xav tau ntawm cov txheej txheem ntau lawm, txheej tiv thaiv lossis txhim kho cov xeb ua tau ntawm graphite crucles tuaj yeem xaiv.
Cntawm ulcusion
Tu graphite crucibles yog cov kauj ruam tseem ceeb hauv kev tswj lawv cov kev ua tau zoo thiab nthuav lawv lub neej pabcuam. Los ntawm kev tshem tawm cov av thiab cov seem, nrog rau cov kauj ruam uas tsim nyog ntxuav, nws tuaj yeem ua kom tau cov txheej txheem tu kom tsim nyog uas tsim nyog tias kev ua haujlwm siab. Nyob rau hauv lub teb ntawm cov hlau smelting thiab kev tswj kom sov siab, tswj kev huv ntawm cov crucibless yog tus yuam sij los ua kom muaj kev tsim khoom zoo.
