Itekhnoloji yokuvelisa i-graphite-silicon carbide crucible

Ukwakhiwa kwemathiriyeli ekrwada of graphite-silicon carbide cruciblesngumxube olungelelanisiweyo olungelelanisiweyo wezinto ezahlukahlukeneyo, ngalinye lifak’ isandla kwiimpawu ezizodwa zemveliso yokugqibela. Yenziwe ngeflake graphite, isilicon carbide, elemental silicon powder, boron carbide powder kunye nodongwe, ipesenti yobunzima bezi zinto zikrwada idlala indima ebalulekileyo ekumiseleni iipropathi ze-crucible.

Inkqubo yokwenziwa kwe-graphite-silicon carbide crucibles luluhlu lwamanyathelo anobunono aqinisekisa umgangatho kunye nokuthembeka kwemveliso yokugqibela. Iimathiriyeli ekrwada ziqale zixutywe ngokulinganayo ukuze zenze uludaka olufanelekileyo, oluthi ke lufakwe kubumba kwaye lucinezelwe kwimilo kusetyenziswa umshicileli we-isostatic. Isiphumo esingenanto sisomiswa kwaye sigqunywe ngeglaze ekhuselayo, ethi emva koko ifakwe i-oxidized kwaye inyibilikiswe kwiglasi ekhazimulayo ngenkqubo yokudubula ehamba ze. Imveliso egqityiweyo emva koko ihlolwe kwaye ithathwa njengelungele ukusetyenziswa.

Yintoni ekhethekileyo malunga nale nkqubo yokuvelisa ukulula kwayo kunye nokusebenza okugqwesileyo kwee-crucibles ezibangelwayo. I-crucible ine-texture efanayo, ubuninzi obuphezulu, i-porosity ephantsi, i-conductivity ye-thermal ekhawulezayo kunye nokumelana nokuqina kwe-corrosion. Ezi mpawu zenza kube yinto efanelekileyo kwiintlobo ezahlukeneyo zezicelo, ngakumbi kumashishini apho amaqondo okushisa aphezulu kunye neekhemikhali ezinzima ziqhelekileyo.

Enye inkalo ephawulekayo yenkqubo yokuvelisa kukusetyenziswa kodongwe njengesibophelelo. Olu khetho lusebenza kwiinjongo ezimbini njengoko alufaki nje igalelo ekusebenzeni okunqwenelekayo kwe-crucible kodwa lukwanciphisa iinkxalabo zokusingqongileyo. Le nkqubo isebenzisa udongwe njengesibophelelo ukunqanda ukubola kunye nokukhululwa kwezinto ezinobungozi ezifana ne-phenolic resin okanye i-tar, enokuthi ngenye indlela ivelise umsi onobungozi kunye nothuli ngexesha lenkqubo yokudubula kwaye ingcolise indalo.

Isishwankathelo, ukwakhiwa kwezinto eziluhlaza kunye nenkqubo yokuvelisa i-graphite silicon carbide crucible ibonisa ukuhlanganiswa okuhambelanayo kwesayensi kunye neteknoloji kunye nokwazisa ngokusingqongileyo. Iimveliso ezibangelwayo zibubungqina bobuchule beenkqubo zokuvelisa zanamhlanje, ezibonelela ngezisombululo ezinokwethenjelwa nezizinzileyo kumashishini afuna ii-crucibles eziphezulu zokusebenza.
