I-Crucible
Incazelo Yomkhiqizo
I-Silicon carbide crucibles iwuhlobo lwesitsha sobumba se-ceramic esijulile. Uma kwenzeka okuqinile kushiswa ngomlilo omkhulu, kuzosetshenziswa i-crucible. I-silicon carbide crucible ikwazi kangcono ukumelana namazinga okushisa aphakeme kune-glassware, futhi okokusebenza ekubumbeni okuzoncibilikiswa ngeke kugcwale kakhulu, ukuvimbela okokushisa okushisayo ukuthi kugxume kuphume futhi kuvumele umoya ukuthi ufinyelele mahhala ukuthola ukusabela okwenzeka nge-oxidation. Ngoba iphansi le-crucible lincane kakhulu, i-crucible ngokuvamile idinga ukuma kunxantathu we-pipeclay ngokushisa ngqo emlilweni.
I-crucible ingabekwa kunxantathu wensimbi ngendlela emile noma ehlukanisiwe, futhi ingahlelwa wedwa ngokuya ngezidingo zesilingo. Ngemuva kokushisa, i-crucible ngeke ibekwe ngokushesha etafuleni elibandayo lensimbi, ukuvimbela ukuqhekeka ngenxa yokupholisa okubukhali, futhi futhi ngeke kubekwe ngokushesha etafuleni lokhuni, ukuvimbela ukushisa ideskithophu noma ukubangela umlilo.
Isicelo
I-Silicon carbide crucibles isetshenziswa kakhulu ekusetshenzisweni kwensimbi, ekubunjweni, emishini, emakhemikhali nakweminye imikhakha yezimboni, futhi isetshenziselwa kakhulu ukuncibilikisa ingxubevange yensimbi yensimbi nokuhlanganiswa kokuncibilikisa okusansimbi nama-alloys, futhi imiphumela yezobuchwepheshe nezomnotho mihle.
Isici
It has conductivity ezishisayo ezinhle futhi lokushisa eliphezulu ukumelana. Enkambisweni yokusebenzisa izinga lokushisa okuphezulu, i-coefficient yokwandiswa okushisayo incane, futhi inokumelana okuthile nobunzima ekushiseni okusheshayo nokupholisa okusheshayo.
Inokumelana nokugqwala okuqinile kwisisombululo se-acid ne-alkaline nokuqina kwamakhemikhali okuhle kakhulu.
Uma kuqhathaniswa ne-graphite crucible, i-silicon carbide crucible inezimpawu zamandla amakhulu wevolumu, ukumelana nokushisa okuphezulu, ukudlulisa ukushisa okusheshayo, ukumelana ne-acid ne-alkali, amandla okushisa aphezulu kanye nokumelana okuphezulu kwe-oxidation.
Impilo yesevisi yinde ngokuphindwe ka-3-5 kunombumba we-graphite crucible.
