Inkqubo yobushushu yesithando sekristale esinye esithe nkqo ikwabizwa ngokuba yintsimi yobushushu. Umsebenzi wenkqubo ye-graphite thermal field ubhekisa kuyo yonke inkqubo yokunyibilikisa izinto zesilicon nokugcina ukukhula kwekristale enye kubushushu obuthile. Ngamafutshane, yinto epheleleyoinkqubo yokufudumeza igrafayithiyokutsala i-silicon yekristale enye.
Intsimi yobushushu yegrafiti ngokubanzi ibandakanya(izinto zegrafayithi) iringi yoxinzelelo, isigqubuthelo sokukhusela, isigqubuthelo sokukhusela esiphezulu, esiphakathi nesisezantsi,isixhobo sokubethela igrafayithi(isixhobo sokubethela esinamagqabi amathathu), intonga yokuxhasa isixhobo sokubethela esiqhotsiweyo, itreyi yokubethela esiqhotsiweyo, i-electrode, i-heater,ityhubhu yesikhokelo, i-graphite bolt, kwaye ukuze kuthintelwe ukuvuza kwe-silicon, i-furnace esezantsi, i-metal electrode, intonga yokuxhasa, zonke zixhotyiswe ngeepleyiti zokukhusela kunye nezigqubuthelo zokukhusela.
Kukho izizathu ezininzi eziphambili zokusebenzisa ii-electrode zegrafiti kwintsimi yobushushu:
Ukuqhuba kakuhle kakhulu
I-Graphite inombane oqhuba kakuhle kwaye inokuqhuba ngokufanelekileyo umbane kwintsimi yobushushu. Xa intsimi yobushushu isebenza, kufuneka kungeniswe umbane onamandla nge-electrode ukuze kuveliswe ubushushu. I-graphite electrode inokuqinisekisa ukuba umbane udlula ngokuzinzileyo, inciphise ukulahleka kwamandla, kwaye yenze intsimi yobushushu ifudumale ngokukhawuleza kwaye ifikelele kubushushu obufunekayo bokusebenza. Ungacinga ukuba, njengokusebenzisa iingcingo ezikumgangatho ophezulu kwisekethe, ii-graphite electrodes zinokubonelela ngetshaneli yamandla engaphazanyiswayo kwintsimi yobushushu ukuqinisekisa ukusebenza okuqhelekileyo kwentsimi yobushushu.
Ukumelana nobushushu obuphezulu
Intsimi yobushushu idla ngokusebenza kwindawo enobushushu obuphezulu, kwaye i-graphite electrode inokumelana nobushushu obuphezulu kakhulu. Iqondo lokunyibilika kwe-graphite liphezulu kakhulu, ngokubanzi lingaphezulu kwe-3000℃, nto leyo eyenza ukuba ikwazi ukugcina isakhiwo esizinzileyo kunye nokusebenza kakuhle kwintsimi enobushushu obuphezulu, kwaye ayizukuthamba, itshintshe okanye inyibilike ngenxa yobushushu obuphezulu. Nokuba phantsi kweemeko zokusebenza ezinobushushu obuphezulu ixesha elide, i-graphite electrode inokusebenza ngokuthembekileyo kwaye ibonelele ngokufudumeza okuqhubekayo kwintsimi enobushushu.
Uzinzo lweekhemikhali
I-Graphite izinzile kakuhle kwiikhemikhali kumaqondo obushushu aphezulu kwaye akulula ukuyisabela ngokwekhemikhali nezinye izinto ezikwintsimi yobushushu. Kwintsimi yobushushu, kunokubakho iigesi ezahlukeneyo, iintsimbi ezinyibilikisiweyo okanye ezinye iikhemikhali, kwaye i-electrode ye-graphite inokumelana nokukhukuliseka kwezi zinto kwaye igcine ukuthembeka kwayo kunye nokusebenza kwayo. Olu zinzo lweekhemikhali luqinisekisa ukusetyenziswa kwexesha elide kwee-electrode ze-graphite kwintsimi yobushushu kwaye lunciphisa umonakalo kunye nokuphindaphinda kokutshintshwa kwee-electrode okubangelwa ziimpendulo zeekhemikhali.
Amandla oomatshini
Ii-electrode zegrafiti zinamandla athile oomatshini kwaye zinokumelana noxinzelelo olwahlukeneyo kwintsimi yobushushu. Ngexesha lokufakelwa, ukusetyenziswa kunye nokugcinwa kwentsimi yobushushu, ii-electrode zinokusetyenziswa ngamandla angaphandle, njengoxinzelelo lokubambelela ngexesha lokufakelwa, uxinzelelo olubangelwa kukwanda kobushushu, njl. Amandla oomatshini e-electrode yegrafiti ayenza ikwazi ukuhlala izinzile phantsi kwezi xinzelelo kwaye akukho lula ukuyophula okanye ukuyonakalisa.
Ukusebenza kakuhle kweendleko
Ngokwembono yeendleko, ii-electrode zegrafiti zinoqoqosho oluncinci. I-Graphite sisixhobo sendalo esininzi esineendleko eziphantsi zokumba kunye nokucubungula. Kwangaxeshanye, ii-electrode zegrafiti zinobomi obude benkonzo kunye nokusebenza okuthembekileyo, okunciphisa iindleko zokutshintshwa rhoqo kwee-electrode. Ke ngoko, ukusetyenziswa kwee-electrode zegrafiti kwiindawo zobushushu kunokunciphisa iindleko zemveliso ngelixa kuqinisekiswa ukusebenza.
