Kuipa ndi Mayankho a Silicon Carbide Crucibles

Mpweya wopangidwa ndi kaboni wa silicon carbide crucible, amagwiritsidwa ntchito kwambiri m'ma laboratories otentha kwambiri. Izi crucibles amapereka ubwino zosiyanasiyana monga mphamvu mkulu ndi kukana mapindikidwe ndi breakage pa kutentha kwambiri. Komabe, ndikofunikira kudziwa kuti ali ndi zovuta zina zomwe ziyenera kuganiziridwa.

Chimodzi mwazovuta zazikulu za silicon carbide crucibles ndi fragility yawo. Izi crucibles sachedwa kusweka pamene pansi mawotchi mantha pamene ntchito. Zikawonongeka, zimatha kuyambitsa kuyesa kulephera kapena kusokoneza kulondola kwa data yoyesera. Kusatetezeka kumeneku kuyenera kuganiziridwa ndi kusamala koyenera kuchitidwa panthawi yosamalira ndikugwiritsa ntchito.

Kuipa kwina kwa silicon carbide crucibles ndikuti sachedwa kukhudzidwa ndi okosijeni pa kutentha kwambiri. Mukakumana ndi kutentha kwakukulu, wosanjikiza wa oxide ukhoza kupanga pamwamba pa crucible, zomwe zingasokoneze zotsatira zoyesera. Ndikofunikira kupewa okosijeni uku potengera njira zodzitetezera, monga kuphimba pamwamba pa crucible ndi wosanjikiza woteteza.

Kuphatikiza apo, ma silicon carbide crucibles amakhala ndi malire ena chifukwa cha zinthu monga kupanga ndi mtengo wake. Zolepheretsa izi zimatha kuchepetsa kukula, mawonekedwe, ndi mphamvu ya crucible. Chifukwa chake, ofufuza ndi opanga ayenera kuganizira zochepera izi posankha crucibles pazofunikira zawo.

Pofuna kuthana ndi zofooka za silicon carbide crucibles, njira zingapo zilipo. Choyamba, pofuna kukonza moyo wautumiki wa crucible, njira zingagwiritsidwe ntchito kulimbikitsa chithandizo chamkati chamkati kuti chikhale cholimba komanso cholimba. Izi zimathandiza kupewa kusweka ndikuwonjezera moyo wa crucible.

Kachiwiri, pofuna kupewa oxidation, wosanjikiza woteteza angagwiritsidwe ntchito pamwamba pa crucible. Chosanjikiza ichi chimalepheretsa crucible kuti isagwirizane ndi mpweya pa kutentha kwakukulu, motero kulepheretsa mapangidwe a oxide layer.

Pomaliza, kuti mugonjetse malire a silicon carbide crucibles, mapangidwewo amatha kukonzedwa bwino komanso njira zotsogola kwambiri zotsatiridwa. Pochita izi, mawonekedwe akuluakulu, ozama, ndi ovuta kwambiri amatha kupangidwa, kulola kugwiritsa ntchito crucibles mumitundu yambiri yoyesera. Kuphatikiza apo, zida zina monga zoumba zotentha kwambiri zitha kuganiziridwa kuti zitha kulowa m'malo mwa silicon carbide crucibles.

Pomaliza, ma silicon carbide crucibles ali ndi zovuta zina, koma kugwiritsa ntchito kwawo mu labotale kumakhala kopindulitsa kwambiri. Ntchito yonse komanso kusinthasintha kwa ma silicon carbide crucibles amatha kupitilizidwa potenga njira zoyenera ndi kukhathamiritsa kuti athane ndi kufooka kwawo, kutengeka kwa okosijeni, komanso zoperewera. Ofufuza ndi opanga ayenera kuganizira mozama mfundozi posankha zida zoyesera zotentha kwambiri.
