Ama-crucibles eza ngamamodeli nokucaciswa okuhlukahlukene, anikezela ngezinhlelo eziningi ezahlukahlukene ngaphandle kokunqunyelwa isikali sokukhiqiza, usayizi weqoqo, noma izinhlobonhlobo zezinto ezincibilikayo. Lokhu kuvumelana nezimo kuqinisekisa ukuguquguquka okuqinile futhi kuqinisekisa ubumsulwa bezinto ezincibilikayo.
Imiyalo yokusebenzisa:
Ngemuva kokusetshenziswa, faka i-crucible endaweni eyomile futhi ugweme ukuchayeka emanzini emvula. Ngaphambi kokuyisebenzisa futhi, shisa kancane i-crucible ibe ngama-degrees Celsius angama-500.
Uma ungeza izinto ku-crucible, gwema ukugcwala ngokweqile ukuze uvimbele insimbi ekukhuleni nasekuqhekekeni kwe-crucible ngenxa yokwanda okushisayo.
Lapho ukhipha insimbi encibilikisiwe ku-crucible, sebenzisa isipuni noma nini lapho kungenzeka futhi unciphise ukusetshenziswa kwezindlawu. Uma izindlawu noma amanye amathuluzi kudingekile, qinisekisa ukuthi ahambisana nokuma kwe-crucible ukuvimbela amandla amaningi enziwe endaweni futhi andise ubude bayo bempilo.
Ubude besikhathi se-crucible buthintwa ukusetshenziswa kwayo. Gwema ukuqondisa amalangabi e-high-oxidation ngqo ku-crucible, njengoba lokhu kungabangela ukukhishwa kwe-oxidation ngokushesha kwempahla e-crucible.
Izinto Zokukhiqiza Ezimbaxakayo: Izinto zokukhiqiza zama-crucible zingafingqwa zibe izinhlobo ezintathu eziyinhloko: i-crystalline yemvelo yegraphite, ubumba lwepulasitiki oluphikisayo, nezinto eziqinile ezifana ne-kaolin ezibaliwe. Kusukela ngo-2008, izinto zokwenziwa ezimelana nokushisa okuphezulu okufana ne-silicon carbide, i-alumina corundum, ne-silicon iron nazo zisetshenziswe njengezinto zohlaka lwezinsimbi. Lezi zinto ezisetshenziswayo zithuthukisa kakhulu ikhwalithi, ukuminyana, namandla emishini emikhiqizo ebhobokayo.
Izicelo: I-crucibles ivame ukusetshenziselwa:
Ukushisa izinto eziqinile
Ukuhwamuka, ukugxilisa ingqondo, noma i-crystallization yezixazululo (uma izitsha ezihwamukayo zingatholakali, ama-crucibles angasetshenziswa esikhundleni salokho)
Amanothi Okusetshenziswa Okubalulekile:
Ama-crucibles angashiswa ngokuqondile, kodwa akufanele apholile ngokushesha ngemva kokushisa. Sebenzisa izindlawu ezihlabayo ukuze uzibambe lapho kushisa.
Beka i-crucible kunxantathu wobumba ngesikhathi sokushisa.
Govuza okuqukethwe uma kuhwamuka futhi usebenzise ukushisa okusalayo ukuze wome cishe ngokuphelele.
Ukuhlukaniswa Kwezinsimbi: Ama-crucibles angahlukaniswa kabanzi abe yizigaba ezintathu: izinsimbi ze-graphite, izinsimbi zobumba, nezinsimbi zensimbi. Ngaphakathi kwesigaba se-graphite crucible, kunezinsimbi ze-graphite ezijwayelekile, izinsimbi ze-graphite ezimise okukhethekile, nezinsimbi ze-graphite ezihlanzekile. Uhlobo ngalunye lwe-crucible luyahluka ekusebenzeni, ukusetshenziswa, nezimo zokusebenza, okuholela ekuhlukeni kwezinto ezingavuthiwe, izindlela zokukhiqiza, amasu okukhiqiza, kanye nokucaciswa komkhiqizo.
Ukucaciswa nokubala izinombolo: Ukucaciswa kwe-crucible (osayizi) kuvame ukuchazwa ngezinombolo ezilandelanayo. Isibonelo, i-crucible #1 ingabamba umthamo we-1000g yethusi futhi ibe nesisindo esingu-180g. Amandla okuncibilika ezinsimbi noma ama-alloys ahlukene angabalwa ngokuphindaphinda isilinganiso sevolumu nesisindo se-crucible ngensimbi efanele noma i-alloy coefficient.
Izicelo Ezikhethekile: I-Nickel crucibles ifanele amasampula okuncibilika aqukethe i-NaOH, Na2O2, Na2CO3, NaHCO3, ne-KNO3 kuzincibilikisi ze-alkaline. Nokho, awafaneleki ukuncibilika amasampuli aqukethe i-KHSO4, NaHS04, K2S2O7, noma Na2S2O7, noma ezinye izinyibilikisi ezine-asidi, kanye nama-alkaline sulfide aqukethe isulfure.
Sengiphetha, ama-crucibles anikezela ngezinhlobonhlobo zezinhlelo zokusebenza ezimbonini ezahlukahlukene, futhi ngokulandela imihlahlandlela yokusetshenziswa efanele, ukuphila kwabo isikhathi eside nokusebenza kahle kungakhuliswa.
