Kutheni sifuna igraphite kwintsimi ye-thermal yesithando somlilo sekristale enye

Inkqubo yokufudumala yesithando somlilo sekristale esithe nkqo ikwabizwa ngokuba yintsimi ye-thermal. Umsebenzi we-graphite thermal field system ubhekisa kuyo yonke inkqubo yokunyibilikisa izinto zesilicon kunye nokugcina ukukhula kwekristale enye kwiqondo lobushushu elithile. Ngamafutshane, ipheleleinkqubo yokufudumeza igraphiteyokutsala i-silicon enye yekristale.

Igraphite thermal field ngokubanzi ibandakanya(izinto zegraphite) umsesane woxinzelelo, isigqubuthelo sogqume, phezulu, esiphakathi nasezantsi,i-graphite crucible(i-crucible-petal crucible), intonga yokuxhasa i-crucible, i-tray ye-crucible, i-electrode, i-heater,ityhubhu yesikhokelo, i-graphite bolt, kunye nokuthintela ukuvuza kwe-silicon, i-furnace bottom, i-electrode yensimbi, intonga yokuxhasa, zonke zixhotyiswe ngamacwecwe okukhusela kunye nezikhuselo zokukhusela.

Kukho izizathu ezininzi eziphambili zokusebenzisa i-electrode yegraphite kwindawo eshushu:

I-conductivity egqwesileyo

I-graphite ine-conductivity elungileyo yombane kwaye inokuqhuba ngokufanelekileyo ngoku kwintsimi ye-thermal. Xa intsimi ye-thermal isebenza, i-current eqinile kufuneka ifakwe nge-electrode ukuvelisa ukushisa. I-electrode yegraphite inokuqinisekisa ukuba i-current idlula ngokuzinzileyo, ukunciphisa ukulahleka kwamandla, kwaye yenza intsimi ye-thermal ifudumale ngokukhawuleza kwaye ifikelele kwiqondo lokushisa elifunekayo. Unokucinga ukuba, njengokuba usebenzisa iingcingo eziphezulu kwisekethe, i-electrodes yegraphite inokubonelela ngeshaneli yangoku engabonakaliyo kwintsimi ye-thermal ukuqinisekisa ukusebenza okuqhelekileyo kwintsimi ye-thermal.

Ukumelana nobushushu obuphezulu

Intsimi eshushu idla ngokusebenza kwindawo yobushushu obuphezulu, kwaye i-electrode yegraphite inokumelana namaqondo obushushu aphezulu kakhulu. Indawo yokunyibilika yegraphite iphezulu kakhulu, ngokubanzi ngaphezu kwe-3000 ℃, eyenza ukuba igcine isakhiwo esizinzileyo kunye nokusebenza kwintsimi ye-thermal yobushushu obuphezulu, kwaye ayiyi kuthambisa, iguqule okanye inyibilike ngenxa yokushisa okuphezulu. Naphantsi kweemeko zokusebenza kwexesha elide lobushushu obuphezulu, i-electrode yegraphite inokusebenza ngokuthembekileyo kwaye inikeze ukufudumeza okuqhubekayo kwintsimi ye-thermal.

Uzinzo lwekhemikhali

I-graphite inozinzo oluhle lweekhemikhali kumaqondo aphezulu kwaye akulula ukusabela ngamakhemikhali kunye nezinye izinto kwintsimi ye-thermal. Kwintsimi ye-thermal, kunokubakho iigesi ezahlukeneyo, isinyithi esityhidiweyo okanye ezinye iikhemikhali, kunye ne-graphite electrode inokumelana nokukhukuliseka kwezi zinto kwaye igcine ingqibelelo kunye nokusebenza kwayo. Oku kuzinza kweekhemikhali kuqinisekisa ukusetyenziswa kwexesha elide kwee-electrode zegraphite kwintsimi ye-thermal kunye nokunciphisa umonakalo kunye nokutshintshwa kwe-electrodes ebangelwa yi-chemical reactions.

Amandla omatshini

I-electrode yegraphite inamandla athile omatshini kwaye inokumelana noxinzelelo oluhlukeneyo kwintsimi ye-thermal. Ngethuba lokufakela, ukusetyenziswa kunye nokugcinwa kwentsimi ye-thermal, i-electrodes inokuthi ixhomekeke kumandla angaphandle, njengamandla okudibanisa ngexesha lofakelo, uxinzelelo olubangelwa ukwanda kwe-thermal, njl. uxinzelelo kwaye akukho lula ukuphuka okanye ukonakala.

Ukusebenza kweendleko

Ngokombono weendleko, i-electrode yegraphite inoqoqosho. Igraphite bubutyebi bendalo obuninzi obunemigodi ephantsi kunye neendleko zokuyilungisa. Ngelo xesha, i-electrode yegraphite inobomi obude benkonzo kunye nokusebenza okuthembekileyo, ukunciphisa iindleko zokutshintshwa rhoqo kwe-electrode. Ngoko ke, ukusetyenziswa kwee-electrode zegraphite kwiindawo ezishushu kunokunciphisa iindleko zokuvelisa ngelixa uqinisekisa ukusebenza.
