Iielectrode zegraphite zidlala indima ebalulekileyo kwizicelo ezahlukeneyo zemizi-mveliso, ikakhulu kwiziko lombane apho zisebenza njengamacandelo okuqhuba ukwenza lula ukunyibilikiswa nokusulungekiswa kwesinyithi.Ukuhanjiswa kombane kwee-electrode zegraphite kubalulekileigraphite electrode uphawuechaphazela ngokuthe ngqo ukusebenza kunye nokusebenza kakuhle kwezi nkqubo.
Zeziphi izinto ezichaphazela ukuhanjiswa kombane wegraphite electrode?
Mna:Pukuqina kunye nomgangatho wegraphite esetyenziswa kwimveliso yabo
Igraphite ekumgangatho ophezulu kunye namanqanaba aphantsi okungcola, ngakumbi umxholo wesulfure, ubonisa ukuhanjiswa kombane okungcono.Ukungcola kwigraphite kunokuphazamisa ukuhamba kwee-electron, ukwandisa ukuchasana nokunciphisa umbane we-electrode.Ke ngoko, abavelisi kufuneka bakhethe ngononophelo kwaye basebenze izixhobo zegraphite ukuze baqinisekise ukuhanjiswa kombane ngokufanelekileyo.
II:Gubungakanani bemvula yamasuntswana egraphite asetyenziswa ekubunjweni kwawo
Ubungakanani bengqolowa obuncinci bubangela ukunyuka kombane ngenxa yobuninzi beendawo zoqhagamshelwano phakathi kweengqungquthela zegraphite.Oku kuququzelela ukuhanjiswa lula kwee-electron kwisakhiwo se-electrode, ngaloo ndlela kuphuculwe ukuhanjiswa kombane.Abavelisi bahlala besebenzisa iindlela ezikhethekileyo zokusila kunye neendlela zokusila ukuze bafezekise ubungakanani obufunwayo benkozo, ngaloo ndlela bephucula ukusebenza kwe-electrode.
III:Cukubekwa kwesixhobo sokubopha esisetyenziswa kwimveliso yeeelectrode zegraphite
Isibophelelo, esiqhele umxube wetha yetha kunye nepetroleum coke, sisebenza njenge arhente ebophelelayoinkqubo yokuvelisa i-electrode.I-conductivity ye-binder material ngokwayo inokuchaphazela ukuhanjiswa kombane jikelele kwe-electrode.Ke ngoko, ukukhetha i-binder material ene-conductivity ephezulu yombane kubalulekile ukuqinisekisa ukusebenza kakuhle kwe-electrode yegraphite.
IV:Dukuqina kunye ne-porosity ye-electrode yegraphite
Ubuninzi be-electrode ephezulu, ephunyezwe ngokunyanzeliswa ngokufanelekileyo ngexesha lenkqubo yokuvelisa, kwandisa ukuhanjiswa kombane ngokunciphisa inani le-voids okanye i-pores.Ezi voids zisebenza njengemiqobo ekuhambeni kweentlawulo zombane, ukwandisa ukuchasana kunye nokuthintela ukuqhuba.Ke ngoko, ukugcina ingxinano ye-electrode efanelekileyo kunye nokunciphisa i-porosity kubalulekile ekwandiseni ukuhanjiswa kombane.
V:Singqibelelo yetructural ye-graphite electrode
Kwizicelo zamashishini apho imisinga ephezulu kunye neemeko zokusebenza ezigqithisileyo zibandakanyekayo, ukuxhathisa ukutshatyalaliswa kwe-thermal ye-graphite electrode kuba yinto ebalulekileyo.Njengoko i-conductivity yombane ihambelana ngokusondeleyo kwingqibelelo yesakhiwo se-electrode, nayiphi na i-cracks ye-thermal okanye umonakalo unokuchaphazela kakhulu ukuhanjiswa.Ngoko ke, abavelisi bagxininise ekuveliseni i-electrode yegraphite kunye nokuxhathisa ukothuka okuphezulu kwe-thermal ukuqinisekisa ukuhanjiswa kombane okuzinzileyo ngexesha lokusebenza.
VI:Sukugqiba kwe-urface yee-electrode zegraphite
Ukugqitywa komgangatho ogudileyo kuvumela unxibelelwano olungcono lombane kunye nokunciphisa ukuchasana koqhagamshelwano phakathi kwe-electrode kunye nomqokeleli wangoku.Ukunyanga komphezulu ohlukeneyo, okufana neengubo kunye nokupholisha, kuqeshwa ukuphucula iipropathi zomphezulu wegraphite electrode, ngaloo ndlela ziphucula ukuhanjiswa kombane.
Kubalulekile ukuba uqaphele ukuba ukuqhutyelwa kombane kuphela akunqumi ukusebenza ngokubanzi kwei-electrode yegraphite.Ezinye izinto, ezifana namandla omatshini, ukumelana ne-oxidation, kunye nokuzinza kweekhemikhali, nazo zinegalelo ekusebenzeni kwazo kwizicelo zemizi-mveliso.Ke ngoko, ukuqonda okubanzi kwazo zonke ezi zinto kubalulekile ekukhetheni nasekusetyenzisweni kwee-electrode zegraphite kwiinkqubo ezithile kunye namashishini.
Tyena conductivity yombane we-graphite electrode luphawu olubalulekileyo oluchaphazela ngokuthe ngqo ukusebenza kwabo kwi-industrial applications.Ukuqonda kunye nokulawula le miba kubalulekile ekuphuculeni ukusebenza kwe-electrode kunye nokuqinisekisa ukusebenza ngokufanelekileyo nangokuthembekileyo kwii-arc zombane kunye nezinye iinkqubo ezifanayo.
QHAGAMSHELANA NATHIUKUFUMANA ULWAZI OLULUNGILEYO NGE-GRAPHITE ELECTRODES.
