Clay Graphite Crucible

Khoom:

1. Zoo heev kub kuj:Av nplaum graphite crucibletso siab rau qhov zoo tshaj plaws thermal conductivity ntawm graphite thiab tuaj yeem tiv taus kub txog 1800 ° C yam tsis muaj softening lossis melting. Nws yog tshwj xeeb tshaj yog haum rau kev sim kub thiab kev lag luam smelting.
2. Lub zog siab: Graphite thiab av nplaum tau sib xyaw ua ke los ua cov khoom siv muaj zog sib xyaw, uas ua rau lub crucible tsis tshua muaj kev tawg thaum raug cuam tshuam rau sab nraud thiab muaj lub zog zoo.
3. Muaj zog corrosion kuj: Lub ntuj corrosion kuj ntawm graphite enables av nplaum graphite crucible siv tau ntev nyob rau hauv ntau yam corrosive ib puag ncig, thiab yog tsim rau khaws cia thiab ua ntau yam corrosive daws.

Cov yam ntxwv ntawm kev siv
Clay graphite crucible muaj ntau yam kev siv thiab kev ua tau zoo heev, tshwj xeeb:

1. Kev siv dav: Txawm hais tias hauv kev soj ntsuam hauv chav kuaj, alchemy, lossis lwm yam kev sim tshuaj, av nplaum graphite crucible yog tsim rau ntau yam kev ua haujlwm kub thiab yog qhov kev xaiv zoo tshaj plaws.
2. Lub neej ua haujlwm ntev: Vim nws cov khoom siv zoo tshaj, av nplaum graphite crucibles feem ntau tuaj yeem siv ntau pua zaus, txo qhov zaus thiab nqi hloov.
3. Kev saib xyuas yooj yim thiab yooj yim: Lub crucible nto yog du thiab yooj yim los ntxuav, thiab kev tu txhua hnub yog qhov yooj yim heev, muab cov neeg siv khoom yooj yim.

Cov kev ceev faj
Txhawm rau kom ntseeg tau tias qhov kev ua tau zoo tshaj plaws thiab kev ua haujlwm ntev ntawm cov av nplaum graphite crucible, cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau thaum siv:

1. Tsis txhob oxidizing ib puag ncig: Nws tsis pom zoo kom siv cov crucibles nrog cov khoom, tshuaj lossis cov kev daws teeb meem uas yooj yim oxidized los tiv thaiv oxidative puas tsuaj.
2. Kev xaiv tsim nyog ntawm lub peev xwm: Thaum siv, koj yuav tsum xaiv qhov tsim nyog crucible muaj peev xwm thiab tswj cov tiam ntawm cov cua sov kom tsis txhob muaj kev puas tsuaj rau lub crucible vim qhov kub thiab txias.
3. Tsis txhob siv qhov kub thiab txias mus sij hawm ntev: Hauv cov kev daws teeb meem xws li cov kua qaub muaj zog thiab muaj zog alkali, kev siv lub sij hawm ntev kub yuav tsum raug zam kom ntau li ntau tau kom tsis txhob cuam tshuam rau lub sijhawm ntev ntawm lub crucible.

Hauv kev xaus
Hauv cov ntsiab lus, av nplaum graphite crucible tau dhau los ua cov cuab yeej tseem ceeb rau kev ua haujlwm kub kub hauv chav kuaj thiab chaw ua haujlwm vim nws qhov kub thiab txias tsis kam, siab zog, thiab corrosion kuj. Kev siv thiab kev saib xyuas kom raug tuaj yeem ua kom nws lub neej ua haujlwm ntev thiab kev ua haujlwm ruaj khov. av nplaum graphite crucible qhia dav daim ntawv thov kev cia siab nyob rau hauv smelting, chemical kev lag luam, kuaj thiab lwm yam teb, thiab yog ib qho kev xaiv zoo tagnrho rau koj cov kev sim kub thiab ntau lawm.
