Ezimweni eziningi zezimboni ezisebenzisa amazinga okushisa aphezulu, izitsha zokushisa zidlala indima ebalulekile njengezitsha ezibalulekile zokubamba nokushisa izinto.Izitsha zobumba ze-silicon carbide, ngokusebenza kwazo okuhle kakhulu, kancane kancane ziba ukukhetha okuthandwayo emikhakheni eyahlukahlukene.
1. Iyini i-silicon carbide ceramic crucible
I-Silicon carbide ceramic crucible iyisitsha esinomumo wesitsha esijulile esenziwe kakhulu ngezinto ze-silicon carbide ceramic. I-Silicon carbide iyinhlanganisela enezibopho eziqinile ze-covalent, futhi ukubopha kwayo kwamakhemikhali okuyingqayizivele kunikeza izitsha eziqinile izakhiwo eziningi ezinhle kakhulu. Uma kuqhathaniswa nezitsha ezivamile zeglasi, izitsha eziqinile ze-silicon carbide ceramic zingamelana namazinga okushisa aphezulu futhi zingamathuluzi afanele okushisa okuphezulu.
2, Izinzuzo zeSilicon Carbide Ceramic Crucibles
1. Ukumelana okuhle kakhulu nokushisa okuphezulu: Izitsha zobumba ze-silicon carbide zingamelana namazinga okushisa afinyelela cishe ku-1350 ℃. Amandla ezinto ezivamile ze-ceramic azoncipha kakhulu ku-1200 ℃, kuyilapho amandla okugoba e-silicon carbide esengagcinwa ezingeni eliphezulu ku-1350 ℃. Lesi sici senza ukuthi isebenze kahle ekuncibilikeni, ekushiseni kanye nakwezinye izinqubo zokushisa okuphezulu, ihlinzeka ngendawo ezinzile yokushisa okuphezulu kwezinto futhi iqinisekise inqubekela phambili ebushelelezi yenqubo.
2. Ukumelana okuhle nokushiswa kwe-oxidation: Izitsha zobumba ze-silicon carbide ceramic zingagcina ukumelana okuhle nokushiswa kwe-oxidation ezindaweni ezishisa kakhulu. Njengoba okuqukethwe yi-silicon carbide kwanda, ukumelana nokushiswa kwe-oxidation kwe-crucible kuyathuthuka kakhulu. Lokhu kusho ukuthi ayishiswa kalula futhi yonakale ngesikhathi sokusetshenziswa isikhathi eside kwezinga lokushisa eliphezulu, okwandisa kakhulu impilo yayo yesevisi, kunciphisa imvamisa yokufakwa esikhundleni kwe-crucible, futhi kunciphisa izindleko zokukhiqiza.
3. Ukuqina kwamakhemikhali okuhle kakhulu: I-silicon carbide ceramics imelana kakhulu nezixazululo ezibolayo. Ezimbonini ezibandakanya izinto ezahlukahlukene zamakhemikhali ezifana ne-metallurgy kanye nobunjiniyela bamakhemikhali, ayisabelani nezinto zamakhemikhali ehlangana nazo, ngaleyo ndlela iqinisekisa ubumsulwa bezinto ezincibilikisiwe noma ezisabelayo, igweme ukungeniswa kokungcola, futhi ithuthukise ikhwalithi yomkhiqizo.
4. Ukuqina okuphezulu kanye nokumelana nokuguguleka: I-silicon carbide inokuqina okuphezulu, okwenza i-crucible ekhiqizwayo ibe nokumelana okuhle nokuguguleka futhi ingamelana nokuguguleka ngokomzimba emazingeni okushisa aphezulu. Ngesikhathi sokusetshenziswa isikhathi eside, ingagcina ubuqotho besimo sayo futhi ayiguguleki kalula noma ikhubazeke, okuqinisekisa ukusebenza kwayo kanye nokuphila kwayo kwenkonzo.
3, Amasimu Okusetshenziswa Kwezinto Ezisetshenziswayo Ze-Silicon Carbide Ceramic
1. Imboni ye-Metallurgical: Kungakhathaliseki ukuthi ukucwengisiswa kwezinsimbi zensimbi njengensimbi, noma ukuncibilika kwezinsimbi ezingezona ezensimbi kanye nezinsimbi zazo ezifana nethusi, i-aluminium, i-zinc, njll., izitsha ze-silicon carbide ceramic zidlala indima ebalulekile. Zingamelana nokuguguleka koketshezi lwensimbi olushisa kakhulu, ziqinisekise inqubekela phambili ebushelelezi yenqubo yokuncibilika kwensimbi, ngenkathi ziqinisekisa ubumsulwa bensimbi futhi zithuthukisa ikhwalithi yemikhiqizo yensimbi.
2. Imboni yamakhemikhali: esetshenziselwa ukusabela kwamakhemikhali okushisa okuphezulu kanye nokwelashwa kwemidiya egqwalisayo. Ngenxa yokuzinza kwayo okuhle kwamakhemikhali kanye nokumelana nokushisa okuphezulu, ingasebenza kahle lapho ibhekene nezinto ezahlukahlukene zamakhemikhali kanye nezindawo zokusabela ezishisa kakhulu, iqinisekisa inqubekela phambili ebushelelezi yokusabela kwamakhemikhali ngenkathi ivimbela i-crucible ngokwayo ukuthi ingonakaliswe futhi yonakale.
3. Ihhavini lezimboni: lisetshenziswa njengesitsha sokushisa sokubasa izinto ezahlukahlukene zezimboni, njengezitini ezingashi. Ngokusebenzisa ukuhanjiswa kwayo okuhle kokushisa kanye nokumelana nokushisa okuphezulu, lingadlulisa ukushisa ngokushesha nangokulinganayo, liqinisekise ikhwalithi yokushisa kwezinto, futhi lithuthukise ukusebenza kahle kokusetshenziswa kwamandla.
Izitsha zobumba ze-silicon carbide ceramic, ezinochungechunge lwezinzuzo ezifana nokumelana nokushisa okuphezulu, ukumelana nokushiswa kwe-oxidation, ukumelana nokuguguleka, kanye nokuqina kwamakhemikhali, zibonise inani elikhulu lokusetshenziswa ezimbonini eziningi futhi ziyizitsha ezifanele kakhulu emkhakheni wezimboni oshisa kakhulu. Ngokuthuthuka okuqhubekayo kanye nokusungula izinto ezintsha kwezobuchwepheshe, sikholelwa ukuthi izitsha zobumba ze-silicon carbide ceramic zizosetshenziswa emikhakheni eminingi futhi zinikeze ukwesekwa okuqinile ekuthuthukisweni kwezimboni ezahlukahlukene.
