I-graphite carbon crucible

I-graphite carbon cruciblesisikhongozeli esikhethekileyo esisetyenziswa kwindawo ezinobushushu obuphezulu ukunyibilika nokujula isinyithi, iiseramikhi, kunye nezinye izinto. Yenziwe ngokuyintloko kwigraphite, inikezela nge-thermal conductivity ekhethekileyo, ukunganyangeki kweekhemikhali, kunye nokuchasana nokutshatyalaliswa kwe-thermal. Ezi zakhiwo zenza iicrucibles zegraphite zilungele iinkqubo ezahlukeneyo zemizi-mveliso, kubandakanya ukunyibilikisa iintsimbi ezingenayo intsimbi njengobhedu, ubhedu, kunye nealuminium.

Ubungakanani becrucible

Izixhobo kunye noKwakha
Iicrucibles zegraphite zenziwe ngezinto ezininzi:

• Igraphite (45-55%): Icandelo eliphambili, libonelela ngokugqithiswa kobushushu kunye nokuzinza kwe-thermal.
• I-silicon carbide, i-silica, kunye nodongwe: Ezi zixhobo zongeza amandla omatshini we-crucible kunye nokuxhathisa ukubola, ngakumbi kwiindawo zokushisa ezigqithisileyo.
• Isibophelelo sodongwe: Ukuqinisekisa ukuhambelana okufanelekileyo kwezinto eziphathekayo, ukunika i-crucible imilo yayo kunye nokunyaniseka kwesakhiwo.

Ubungakanani besuntswana legraphite elisetyenzisiweyo nalo liyahluka ngokuxhomekeke kubukhulu be-crucible kunye nenjongo. Ngokomzekelo, ii-crucibles ezinkulu zisebenzisa i-graphite e-coarser, ngelixa ii-crucibles ezincinci zifuna i-graphite ephucukileyo ukwenzela ukuchaneka okungcono kunye nokusebenza.

Usetyenziso lweGraphite Crucible
I-graphite carbon crucibles isetyenziswa ngokubanzi kumacandelo ahlukeneyo:

• Ukuphosa isinyithi esingenantsimbi: Ilungele iintsimbi ezifana nobhedu, igolide, isilivere kunye nobhedu ngenxa ye-coefficient ephantsi yokwandiswa kwe-thermal.
• Iziko lokungeniswa: Kwezinye iimeko, ii-crucibles zenzelwe ukusebenza kunye nee-frequencies ezithile zesithando somlilo ukunyusa ukusebenza kakuhle kwamandla kunye nokulawula ukushisa.
• Ukulungiswa kweekhemikhali: Uzinzo lwazo lweekhemikhali luzenza zilungele ukusetyenziswa kwiindawo ezivezwe kwizinto ezineasidi okanye zealkaline.

Iingcebiso zokuLondoloza okuBalulekileyo
Ukwandisa ubomi be-graphite carbon crucible, ukhathalelo olufanelekileyo kunye nokugcinwa kubalulekile:

1. Ukupholisa: Qinisekisa ukuba i-crucible ipholisa ngokupheleleyo phambi kokugcinwa ukunqanda ukothuka kwe-thermal.
2. Ukucoca: Soloko ususa intsalela yesinyithi kunye ne-flux emva kokusetyenziswa ngakunye ukuthintela ungcoliseko.
3. Ugcino: Gcina i-crucible kwindawo eyomileyo, kude nemithombo yokushisa ngokuthe ngqo, ukuphepha ukufunxa ukufuma, oku kunokukhokelela ekuthotyweni kwesakhiwo.

Imibuzo Ebuzwa Rhoqo (FAQ)

1. Ingaba i-graphite crucible ihlala ixesha elingakanani?
   Ubude bokuphila buyohluka ngokuxhomekeke ekusebenziseni, kodwa ngokugcinwa okufanelekileyo, iicrucibles zegraphite zingahlala kwimijikelo emininzi yokunyibilika, ngakumbi kwizicelo zokuphosa isinyithi esingeyontsimbi.
2. Ngaba ii-graphite crucibles zinokusetyenziswa kuzo zonke iintlobo zeziko?
   Ngelixa izinto eziguquguqukayo, i-crucible material kufuneka ihambelane nohlobo lwesithando somlilo. Ngokomzekelo, ii-crucibles ze-intduction furnaces zifuna ukuxhatshazwa kombane okuthe ngqo ukunqanda ukushisa.
3. Leliphi elona qondo lobushushu linokumelana ne graphite crucible?
   Ngokuqhelekileyo, i-graphite crucibles inokusingatha ukushisa ukusuka kwi-400 ° C ukuya kwi-1700 ° C, kuxhomekeke ekubunjweni kwezinto kunye nokusetyenziswa.
