I-Crucibles Ethembekile Yokuncibilika Nokusakaza
incazelo
I-graphite crucible, eyaziwa nangokuthi i-copper clad encibilikisiwe, ithusi elincibilikisiwe, njll., ibhekisela ohlotsheni lwe-crucible ekhishwe ku-graphite, ubumba, i-silica netshe lengcina.
Izici
Inezici zokumelana nokushisa okuphezulu, ukuguquguquka okuqinile kwe-thermal, ukumelana nokugqwala okuhle nempilo ende yesevisi.Enkambweni yokusetshenziswa kwezinga lokushisa eliphezulu, i-coefficient yokwanda okushisayo incane, futhi inokumelana nokucindezeleka okuthile ekupholiseni okusheshayo nokushisa okusheshayo.Inokumelana nokugqwala okuqinile ezixazululweni ezine-asidi ne-alkaline, inokuqina okuhle kwamakhemikhali, futhi ayihlanganyeli kunoma yikuphi ukusabela kwamakhemikhali phakathi nenqubo yokuncibilikisa.Udonga lwangaphakathi lwe-graphite crucible lubushelelezi, futhi uketshezi lwensimbi oluncibilikisiwe akulula ukuvuza nokunamathela odongeni lwangaphakathi lwe-crucible, ukuze uketshezi lwensimbi lube ne-fluidity enhle kanye ne-castability, futhi lufanele ukubunjwa kwesikhunta okuhlukahlukene.
Inqubo Yokukhiqiza
Inqubo yokukhiqiza i-graphite crucible ingahlukaniswa ngezinhlobo ezintathu: ukubumba ngesandla, ukubunjwa okujikelezayo kanye nokubunjwa kokucindezela.
Isicelo
I-graphite crucibles isetshenziselwa ikakhulukazi ukuncibilikisa izinsimbi ezingenayo insimbi njengethusi, ithusi, igolide, isiliva, i-zinc nomthofu kanye nama-alloys azo.
