Kungani sidinga i-graphite ensimini eshisayo yesithando somlilo se-crystal eyodwa

Isistimu yokushisa yesithando somlilo sekristalu esimile sibizwa nangokuthi insimu eshisayo. Umsebenzi we-graphite thermal field system ubhekisela kulo lonke uhlelo lokuncibilikisa izinto ze-silicon nokugcina ukukhula kwekristalu eyodwa ekushiseni okuthile. Kalula nje, ipheleleuhlelo lokushisa lwe-graphiteyokudonsa i-silicon eyodwa ye-crystal.

Inkambu ye-graphite eshisayo ngokuvamile ihlanganisa(i-graphite material) indandatho yokucindezela, isembozo sokufakelwa, ikhava yokufaka engaphezulu, ephakathi nephansi,i-graphite crucible(i-three-petal crucible), induku yokwesekela, ithreyi eliphehlayo, i-electrode, i-heater,ithubhu lomhlahlandlela, ibhawudi le-graphite, futhi ukuze kuvinjwe ukuvuza kwe-silicon, indawo engezansi yesithando somlilo, i-electrode yensimbi, induku yokusekela, konke kufakwe amapuleti okuzivikela nesembozo sokuzivikela.

Kunezizathu ezimbalwa eziyinhloko zokusebenzisa ama-electrode e-graphite emkhakheni oshisayo:

I-conductivity enhle kakhulu

I-graphite ine-conductivity kagesi enhle futhi ingaqhuba kahle okwamanje endaweni eshisayo. Lapho inkambu eshisayo isebenza, i-current enamandla idinga ukwethulwa nge-electrode ukuze ikhiqize ukushisa. I-electrode ye-graphite ingaqinisekisa ukuthi yamanje idlula ngokuzinzile, inciphise ukulahlekelwa amandla, futhi yenze insimu eshisayo ishise ngokushesha futhi ifinyelele izinga lokushisa elidingekayo. Ungacabanga ukuthi, njengokusebenzisa izintambo zekhwalithi ephezulu kumjikelezo, ama-electrode e-graphite anganikeza isiteshi samanje esingavinjelwe senkundla eshisayo ukuze kuqinisekiswe ukusebenza okuvamile kwendawo eshisayo.

Ukumelana nokushisa okuphezulu

Inkambu eshisayo ngokuvamile isebenza endaweni yokushisa ephezulu, futhi i-electrode ye-graphite ingamelana namazinga okushisa aphezulu kakhulu. Iphuzu lokuncibilika le-graphite liphezulu kakhulu, ngokuvamile lingaphezu kuka-3000℃, eliyenza ikwazi ukugcina ukwakheka okuzinzile nokusebenza endaweni yokushisa ephezulu, futhi ngeke ithambe, yonakale noma incibilike ngenxa yokushisa okuphezulu. Ngisho nangaphansi kwezimo zokusebenza zesikhathi eside zokushisa okuphezulu, i-graphite electrode ingasebenza ngokuthembekile futhi inikeze ukushisa okuqhubekayo kwendawo eshisayo.

Ukuzinza kwamakhemikhali

I-graphite inokusimama okuhle kwamakhemikhali emazingeni okushisa aphezulu futhi akulula ukusabela ngamakhemikhali nezinye izinto endaweni eshisayo. Emkhakheni oshisayo, kungase kube namagesi ahlukahlukene, izinsimbi ezincibilikisiwe noma amanye amakhemikhali, futhi i-graphite electrode ingamelana nokuguguleka kwalezi zinto futhi igcine ubuqotho nokusebenza kwayo. Lokhu kuzinza kwamakhemikhali kuqinisekisa ukusetshenziswa kwesikhathi eside kwama-electrode e-graphite endaweni eshisayo futhi kunciphisa umonakalo kanye nemvamisa yokubuyisela yama-electrode okubangelwa ukusabela kwamakhemikhali.

Amandla omshini

Ama-electrode e-graphite anamandla athile omshini futhi angakwazi ukumelana nokucindezeleka okuhlukahlukene emkhakheni oshisayo. Ngesikhathi sokufakwa, ukusetshenziswa nokugcinwa kwe-thermal field, ama-electrode angase abe ngaphansi kwamandla angaphandle, njengamandla okubamba ngesikhathi sokufakwa, ukucindezeleka okubangelwa ukwanda kokushisa, njll. Amandla omshini we-graphite electrode ayenza ikwazi ukuhlala izinzile ngaphansi kwalezi igcizelela futhi akulula ukuphuka noma ukulimaza.

Ukusebenza kahle kwezindleko

Ngokombono wezindleko, ama-electrode e-graphite ayonga kakhulu. I-graphite iyinsiza yemvelo eningi enezimayini kanye nezindleko zokucubungula eziphansi. Ngesikhathi esifanayo, ama-electrode e-graphite anokuphila kwenkonzo ende nokusebenza okuthembekile, ukunciphisa izindleko zokushintshwa kwe-electrode njalo. Ngakho-ke, ukusetshenziswa kwama-electrode e-graphite ezindaweni ezishisayo kunganciphisa izindleko zokukhiqiza ngenkathi kuqinisekisa ukusebenza.
