Isicelo: Okuvame ukusetshenziswa ekuhlungeni ukungcola, ukuhlolwa kokusabalalisa igesi kanye nezinqubo ezikhethekile zokuncibilikisa ekuncibilikiseni insimbi.
5. I-Silicon Carbide Graphite Crucible
Ukwakheka kwezinto: Kwenziwe ngengxube ye-graphite ne-silicon carbide.
Izici:
Inobunzima obuphezulu kakhulu kanye nokumelana nokugqoka.
Ukumelana nokushisa okuphezulu okuhle kakhulu, okulungele ukusebenza kokushisa okuphezulu kwesikhathi eside.
Isicelo: Isetshenziselwa kakhulu ukuncibilikisa izinsimbi ezincibilika kakhulu njengensimbi nensimbi.
6. I-Isostatic Cindezelwe I-Graphite Crucible
Ukwakheka kwezinto: I-high-density graphite crucible eyenziwe ngobuchwepheshe bokucindezela be-isostatic.
Izici:
Ukuminyana okuphezulu, ukwakheka okufanayo kanye nokumelana nokushaqeka okuhle kokushisa.
Impilo ende yesevisi, ilungele ukuncibilika okunembe kakhulu.
Isicelo: Isetshenziswa ezintweni ze-semiconductor, ukukhiqizwa kwe-silicon eyodwa ye-crystal kanye nocwaningo lwaselabhorethri.
7. I-Composite Graphite Crucible
Ukwakheka kwezinto: Yenziwe nge-graphite nezinye izinto ezisebenza kahle kakhulu (njengefiber ye-ceramic).
Izici:
Ukuhlanganisa izinzuzo ze-graphite nezinye izinto, inamandla aphezulu nokumelana nokushisa.
Ifanele izidingo zokuncibilika ezindaweni ezikhethekile.
Isicelo: Isetshenziswa ekuncibilikiseni izinga lokushisa eliphezulu kwe-alloy nasezindaweni ezikhethekile zezimboni.
8. I-Lab-Scale Graphite Crucible
Ukwakheka kwezinto: Ngokuvamile kwenziwa nge-high-purity graphite.
Izici:
Usayizi omncane, olungele ucwaningo lwaselabhorethri kanye nokuncibilika kwenqwaba encane.
Ukunemba okuphezulu, okufanelekile ukuncibilika kwezinto zokuhlanzeka okuphezulu.
Izicelo: Isetshenziswa ocwaningweni lwaselabhorethri, ukuhlaziya insimbi eyigugu kanye nokuhlolwa kwesayensi yezinto.
9. I-Industrial-Scale Graphite Crucible
Ukwakheka kwezinto: Kwenziwe nge-graphite yamandla aphezulu noma izinto ezihlanganisiwe.
Izici:
Usayizi omkhulu, olungele ukukhiqizwa kwezimboni ezinkulu.
Ukuqina okuqinile, okulungele ukusebenza kokushisa okuphezulu kwesikhathi eside.
Isicelo: Isetshenziswa ku-smelters yensimbi, ama-foundries kanye nokukhiqizwa kwezinto zikagesi.
10. Ngokwezifiso Graphite Crucible
Ukwakheka kwezinto: Izinto ezenziwe ngokwezifiso, osayizi kanye nezingubo zokumboza ngokuya ngezidingo zamakhasimende.
Izici:
Ukuvumelana nezimo okuphezulu ukuhlangabezana nezidingo zenqubo ekhethekile.
Ifanele izimboni ezikhethekile noma izidingo zokuhlola.
Isicelo: Isetshenziselwa ukuncibilika kwensimbi okukhethekile, ukuhlolwa kwezinga lokushisa eliphezulu kanye nezidingo zokwenza ngokwezifiso zezimboni.
Ungakhetha kanjani i-crucible?
Izinto ezincibilikayo: Izinsimbi ezihlukene zidinga izinhlobo ezihlukene zeziphambano. Isibonelo, ama-graphite crucibles ahlanzekile ngokuvamile asetshenziselwa ukuncibilikisa igolide.
Izinga lokushisa elisebenzayo: Qiniseka ukuthi i-crucible ingakwazi ukumelana nezinga lokushisa eliphakeme kakhulu elidingekayo.
Usayizi we-crucible: Khetha usayizi ofanele ngokwenani lokuncibilika.
Izidingo zokumboza: Uma ukumelana nokugqokwa okuphezulu nokumelana nokugqwala kuyadingeka, ama-crucible graphite ahlanganiswe ne-TAC angakhethwa.
Fingqa
Kunezinhlobo eziningi ze-graphite crucibles, ngayinye inokwakheka kwayo okuhlukile, izici zokusebenza kanye nezimo ezisebenzayo. Ukukhetha i-graphite crucible efanelekile kudinga ukucabangela izici ezifana nezinto zokuncibilikisa, izidingo zokushisa, indawo yokusebenzisa kanye nesabelomali. Kungakhathaliseki ukuthi ukuncibilikisa igolide, ukukhiqizwa kwezimboni noma ucwaningo lwaselabhorethri, i-graphite crucible iyithuluzi elisebenza kahle nelithembekile.
