Izici ze-silicon carbide crucible

I-silicon carbide crucibleidume ngokuminyana kwevolumu ephezulu, ukumelana nokushisa okuphezulu, ukudluliswa kokushisa okusheshayo, i-asidi ne-alkali ukumelana nokugqwala, amandla okushisa aphezulu, nokumelana ne-oxidation enamandla. Impilo yesevisi ye-silicon carbide crucible yinde izikhathi ezi-3-5 kune-graphite crucible evamile. Kuyi-accessory efanelekile yohhavini ye-powder sintering ehlukahlukene, ukuncibilikisa insimbi nezinye izikloba zezimboni kwezensimbi, imboni yamakhemikhali, ingilazi neminye imikhakha.

Lapho usebenzisa i-silicon carbide crucibles, kunezinto ezimbalwa okufanele uzikhumbule:

1. Ungagcwalisi i-silicon carbide crucible egcwele kakhulu ngokuncibilika ukuze uvimbele ukuchaphazeka, futhi uvumele umoya ukuthi ungene futhi uphume ngokukhululeka ukuze ubangele ukusabela okungenzeka kwe-oxidation.
2. I-silicon carbide crucible inephansi elincane futhi ngokuvamile idinga ukubekwa kunxantathu wobumba ukuze ifudumale ngokuqondile. I-crucible ingabekwa isicaba noma itshekiswe ku-iron tripod, kuye ngezidingo zokuhlolwa.
3. Ngemva kokushisa, ungabeki i-silicon carbide crucible ngokushesha etafuleni lensimbi elibandayo ukuze ugweme ukuqhekeka ngenxa yokupholisa ngokushesha. Ngokufanayo, ungayibeki phezu kwetafula ngokhuni ukuze ugweme ukuyishisa noma ukubangela umlilo. Indlela efanele ukuyibeka ku-iron tripod ukuze iphole ngokwemvelo noma ukuyibeka enethi ye-asbestos ukuze iphole kancane kancane.

Kafushane, izici eziyingqayizivele ze-silicon carbide crucibles zibenza babaluleke kakhulu ekusetshenzisweni kwezimboni ezihlukahlukene, futhi ukulandela imihlahlandlela yokusetshenziswa efanele kuqinisekisa ukuphila kwabo isikhathi eside nokuphepha.
