I-Clay Graphite Crucible

Izakhiwo:

1. Ukumelana nezinga lokushisa eliphezulu okuhle kakhulu:I-clay graphite crucibleithembele ekushiseni okuhle kakhulu kwegraphite futhi ingamelana namazinga okushisa afika ku-1800°C ngaphandle kokuthambisa noma ukuncibilika. Ifaneleka ngokukhethekile ukuhlolwa kwezinga lokushisa eliphezulu kanye nokuncibilikiswa kwezimboni.
2. Amandla aphezulu: I-graphite nobumba kuhlanganiswe ukwenza into ehlanganisiwe enamandla amakhulu, okwenza i-crucible ibe mancane amathuba okuba iphuke lapho ingaphansi komthelela wangaphandle futhi inokuqina okuhle.
3. Ukumelana nokugqwala okuqinile: Ukumelana nokugqwala kwemvelo kwegraphite kwenza i-clay graphite crucible isetshenziswe isikhathi eside ezindaweni ezigqwala ezihlukahlukene, futhi ifanele ukugcina nokucubungula izixazululo ezihlukahlukene ezigqwalayo.

Izici zokusetshenziswa
I-Clay graphite crucible inezinhlobonhlobo zokusetshenziswa nokusebenza okuhle kakhulu, ikakhulukazi:

1. Ukusebenziseka Okubanzi: Kungakhathaliseki ukuthi ekuhlaziyeni kwaselabhorethri, i-alchemy, noma ezinye izivivinyo zamakhemikhali, i-clay graphite crucible ifaneleka emisebenzini ehlukahlukene yokushisa okuphezulu futhi iyisinqumo esihle.
2. Impilo ende yesevisi: Ngenxa yezinto zayo eziphakeme, izinsimbi ze-clay graphite ngokuvamile zingasetshenziswa izikhathi ezingamakhulu, ukunciphisa kakhulu imvamisa nezindleko zokushintshwa.
3. Ukunakekela okulula futhi okulungele: Indawo eboshekayo ibushelelezi futhi kulula ukuyihlanza, futhi ukunakekelwa kwansuku zonke kulula kakhulu, kuhlinzeka abasebenzisi ngokunethezeka okukhulu.

Izinyathelo zokuzivikela
Ukuze uqinisekise ukusebenza okuhle kakhulu nempilo ende yesevisi ye-clay graphite crucible, amaphuzu alandelayo kufanele anakwe ngesikhathi sokusetshenziswa:

1. Gwema izindawo ze-oxidizing: Akunconywa ukusebenzisa iziphambano ezinezakhi, izinto noma izixazululo ezifakwa kalula i-oxid ukuvimbela ukulimala kwe-oxidative.
2. Ukukhetha okufanelekile komthamo: Uma usebenzisa, kufanele ukhethe umthamo ofanele wokubhoboza futhi ulawule ukukhiqizwa kokushisa ukuze ugweme ukulimala kwe-crucible ngenxa yokwenyuka okungazelelwe kwezinga lokushisa.
3. Gwema ukusetshenziswa kwesikhathi eside kwezinga lokushisa eliphezulu: Ezixazululweni ezonakalisayo ezifana ne-asidi eqinile ne-alkali eqinile, ukusetshenziswa kwesikhathi eside kwezinga lokushisa eliphezulu kufanele kugwenywe ngangokunokwenzeka ukuze kugwenywe ukuthikameza ukuqina kwe-crucible.

Ekuphetheni
Kafushane, i-clay graphite crucible isiyithuluzi elibalulekile ekusebenzeni okunokushisa okuphezulu kuma-laboratories nasezindaweni zezimboni ngenxa yokumelana kwayo okuhle kakhulu nokushisa okuphezulu, amandla aphezulu, nokumelana nokugqwala. Ukusetshenziswa okulungile nokunakekelwa kungaqinisekisa impilo yayo yesevisi ende nokusebenza okuzinzile. I-clay graphite crucible ibonisa amathuba okusebenza abanzi ekuncibilikiseni, embonini yamakhemikhali, elabhorethri neminye imikhakha, futhi iyinketho ekahle yokuhlolwa kwakho kwezinga lokushisa eliphezulu nokukhiqiza.
