I-Crucibles iza kwiimodeli ezahlukeneyo kunye neenkcukacha, inikezela uluhlu olubanzi lwezicelo ngaphandle kokuthintelwa sisikali semveliso, ubungakanani bebhetshi, okanye iintlobo ngeentlobo zezinto ezinyibilikayo. Oku kuguquguquka kuqinisekisa ukuguquguquka okuqinileyo kwaye kuqinisekisa ukucoceka kwezinto ezinyibilikayo.
Imiyalelo yokusebenzisa:
Emva kokusetyenziswa, faka i-crucible kwindawo eyomileyo kwaye ugweme ukubonakaliswa kwamanzi emvula. Phambi kokuba uyisebenzise kwakhona, kancinane ufudumeze i-crucible ukuya kuma-500 degrees celsius.
Xa ukongeza izinto eziphathekayo kwi-crucible, gwema ukugqithisa ukukhusela isinyithi ekwandiseni kunye nokuqhekeza i-crucible ngenxa yokwandiswa kwe-thermal.
Xa ukhupha isinyithi esityhidiweyo kwi-crucible, sebenzisa i-spoon xa kunokwenzeka kwaye unciphise ukusetyenziswa kweetoni. Ukuba iitoni okanye ezinye izixhobo ziyimfuneko, qinisekisa ukuba ziyahambelana nemilo ye-crucible ukukhusela amandla amaninzi asekuhlaleni kunye nokwandisa ubomi bayo.
Ubomi be-crucible buchatshazelwa kukusetyenziswa kwayo. Gwema ukuqondisa amadangatye aphezulu-oxidation ngokuthe ngqo kwi-crucible, njengoko oku kunokubangela i-oxidation ekhawulezayo yezinto eziqhekezayo.
Izinto zokwenziwa kwe-Crucible Manufacturing Materials: Izinto zokuvelisa ii-crucibles zinokushwankathelwa zibe ziindidi ezintathu eziphambili: i-crystalline yendalo yegraphite, i-plastic refractory clay, kunye ne-calcined hard-like materials ezifana ne-kaolin. Ukususela ngo-2008, izinto zokwenziwa ezinobushushu obuphezulu ezifana ne-silicon carbide, i-alumina corundum, kunye ne-silicon iron nazo zisetyenzisiwe njengezixhobo zesikhokelo se-crucibles. Ezi zixhobo zongeza kakhulu umgangatho, ubuninzi, kunye namandla omatshini weemveliso ezinqamlekileyo.
Izicelo: Izibonda zidla ngokusetyenziselwa:
Ukutshisa izinto eziqinileyo
I-Evaporation, i-concentration, okanye i-crystallization yezisombululo (xa izitya ezikhuphayo zingekho, ii-crucibles zingasetyenziselwa endaweni yoko)
Amanqaku osetyenziso olubalulekileyo:
I-Crucibles inokufudumeza ngokuthe ngqo, kodwa akufanele ipholiswe ngokukhawuleza emva kokufudumeza. Sebenzisa i-crucible tongs ukuze uziphathe xa zishushu.
Beka i-crucible kunxantathu wodongwe ngexesha lokufudumala.
Gqugquzela iziqulatho xa usiba ngumphunga kwaye usebenzise ubushushu obushiyekileyo malunga nokoma okukufutshane.
Ukuhlelwa kweeCrucibles: Izibonda zingahlulwa ngokubanzi zibe ngamacandelo amathathu: ii-graphite crucibles, i-clay crucibles, kunye ne-metal crucibles. Ngaphakathi kwinqanaba le-graphite crucible, kukho i-graphite crucibles eqhelekileyo, i-graphite crucibles ekhethekileyo, kunye ne-high-purity crucibles ye-graphite. Uhlobo ngalunye lwe-crucible luhluke ekusebenzeni, ukusetyenziswa, kunye neemeko zokusebenza, ezikhokelela ekuhlukeni kwezinto eziphathekayo, iindlela zokuvelisa, iindlela zokuvelisa, kunye neenkcukacha zemveliso.
Iingcaciso kunye nokubala: Inkcazo ye-crucible (ubukhulu) idla ngokuchazwa ngamanani alandelelanayo. Umzekelo, i- #1 crucible ingabamba umthamo we-1000g yobhedu kwaye inobunzima be-180g. Umthamo wokunyibilika kwiitsimbi ezahlukeneyo okanye i-alloys ingabalwa ngokuphindaphinda umlinganiselo we-crucible volume-to-weight ratio ngentsimbi efanelekileyo okanye i-alloy coefficient.
Izicelo eziKhethekileyo: Ii-nickel crucibles zifanelekile kwiisampuli ezinyibilikayo eziqukethe i-NaOH, i-Na2O2, i-Na2CO3, i-NaHCO3, kunye ne-KNO3 kwii-solvents ze-alkaline. Nangona kunjalo, azifanelekanga ukunyibilika iisampulu eziqulethe i-KHSO4, i-NaHS04, i-K2S2O7, okanye i-Na2S2O7, okanye ezinye izinyibilikisi ezine-acidic, kunye ne-alkaline sulfides equkethe i-sulfure.
Ukuqukumbela, ii-crucibles zibonelela ngoluhlu olwahlukeneyo lwezicelo kumashishini ahlukeneyo, kwaye ngokulandela izikhokelo zokusetyenziswa ezifanelekileyo, ixesha elide kunye nokusebenza kakuhle kunokwandiswa.
