Li-electrode tsa graphiteke likarolo tsa bohlokoa ts'ebetsong ea libono tsa arc, tse phethang karolo ea bohlokoa lits'ebetsong tse fapaneng tsa indasteri.
Li-electrode tsa graphite li entsoe haholo ka mofuta oa carbon o bitsoang graphite, e leng mofuta oa kristale oa element element carbon.Graphite e na le thepa e ikhethang e e etsang hore e be e loketseng ho sebelisoa li-electrode, joalo ka ts'ebetso ea eona e phahameng ea motlakase, ho hanyetsa mocheso le lik'hemik'hale tse phahameng, le coefficient e tlase ea katoloso ea mocheso.Mehaho ena e thusa li-electrode tsa graphite ho sebetsa hantle haholo lits'ebetsong tsa sebōpi sa arc.
Themokhoa oa ho etsa li-electrode tsa graphitee akarelletsa mehato e mengata.E qala ka ho khethoa ha thepa ea boleng bo holimo ea graphite, e ntan'o siloa ebe e kopanngoa le thepa e kopanyang, e kang sekontiri sa mashala kapa coke ea petroleum.Motsoako ona o bōptjoa ka mokhoa o lakatsehang oa electrode ho sebelisa mokhoa oa ho bopa.Ka mor'a ho bōptjoa, li-electrode li tlas'a mokhoa oa ho baka ho tlosa binder le ho matlafatsa mohaho oa carbon.Sena se lateloa ke tšebetso ea graphitization, e kenyelletsang ho futhumatsa li-electrode ho mocheso oa likhato tse ka bang 3000 tsa Celsius ho li fetolela graphite.Qetellong, li-electrode li feta letoto la liteko tsa taolo ea boleng ho netefatsa ts'ebetso ea tsona le ho ts'epahala.
Li-electrode tsa graphite li fumana lits'ebetso tse ngata lits'ebetsong tse fapaneng tsa indasteri, haholo libonong tsa motlakase tsa arc.Libōpi tsena li sebelisetsoa ho hlahisa tšepe, moo li-electrode tsa graphite li sebetsang e le lisebelisoa tsa conductive ho hlahisa le ho boloka arc ea motlakase, e qhibilihisang thepa e tala 'me e lumella ho thehoa ha tšepe e qhibilihisitsoeng.Ho feta moo, li-electrode tsa graphite li sebelisoa lits'ebetsong tse ling tsa metallurgic tse kang tlhahiso ea ferroalloys, tšepe ea silicon le calcium carbide.
Bohlokoa ba li-electrode tsa graphite maemong a indasteri bo ke ke ba fetisoa.Ts'ebetso ea bona e phahameng ea mocheso e lumella ho fetisoa ha mocheso hantle, ho nolofalletsang ho qhibiliha ha thepa ka potlako le ka mokhoa o nepahetseng haholoanyane ka har'a libono tsa arc.Li-electrode tsa graphite li boetse li bonts'a khanyetso e ntle ho ts'oenyeho ea mocheso, ho li thibela ho phatloha kapa ho robeha tlas'a maemo a feteletseng a mocheso.Ho tšoarella hona ho tiisa bophelo ba nako e telele ea li-electrode mme ho fokotsa litšenyehelo tsa nako le tlhokomelo.
Ho feta moo, theli-electrode tsa graphite conductivity ea motlakaseke ntlha e 'ngoe ea bohlokoa bohlokoa ba bona ba indasteri.The conductivity e phahameng e etsa hore motlakase o tsamaee hantle ka li-electrode, e leng se etsang hore ho be le arc e tsitsitseng le e tsitsitseng nakong ea ho qhibiliha.Sena se tiisa kabo e tšoanang le e laoloang ea mocheso, e lebisang ho boleng bo ntlafetseng ba tšepe le ho tsitsisa.
Boholo le boleng ba li-electrode tsa graphite li ama ts'ebetso ea tsona haholo ts'ebetsong ea sebōpi sa arc.Litekanyo tsa li-electrode, tse kang bophara le bolelele ba tsona, li fapana ho itšetlehile ka moralo o khethehileng oa sebōpi le litlhoko tsa tlhahiso.Baetsi ba hlahisa mefuta e mengata ea boholo ba li-electrode ho amohela mefuta e fapaneng ea sebōpi le bokhoni.
Baetsi ba li-electrode tsa graphitephetha karolo ea bohlokoa ho faneng ka likarolo tsena tsa bohlokoa liindastering lefatšeng ka bophara.Baetsi bana ba tlameha ho khomarela mehato e tiileng ea ho laola boleng ho netefatsa tlhahiso ea li-electrode tse finyellang litekanyetso tsa indasteri.Taolo ea boleng e kenyelletsa liteko bakeng sa thepa ea 'mele, joalo ka bongata le katoloso ea mocheso, hammoho le thepa ea motlakase, joalo ka ho hanyetsa le ho hanyetsa motlakase ka ho khetheha.Ka ho boloka litekanyetso tsa boleng bo tsitsitseng, baetsi ba li-electrode tsa graphite ba kenya letsoho ho sebetsa hantle le tlhahiso ea ts'ebetso ea sebōpi sa arc.
Qetellong, li-electrode tsa graphite li bohlokoa ts'ebetsong ea libono tsa arc mme li bapala karolo ea bohlokoa lits'ebetsong tse ngata tsa indasteri.Thepa ea bona e ikhethang, joalo ka motlakase o phahameng, ho hanyetsa mocheso, le ho tšoarella nako e telele, li etsa hore e be tse loketseng ho sebelisoa lits'ebetsong tsena.Mokhoa oa ho etsa li-electrode tsa graphite o kenyelletsa khetho e hlokolosi ea lisebelisoa tsa boleng bo holimo tsa graphite, tse lateloang ke letoto la mehato e kang ho kopanya, ho etsa sebopeho, ho baka le graphitization.Li-electrode tsa graphite li fumana lits'ebetso tlhahisong ea tšepe le lits'ebetsong tse fapaneng tsa metallurgic.Bohlokoa ba bona ke bokhoni ba bona ba ho fetisa mocheso ka mokhoa o nepahetseng, ho hanyetsa mocheso oa mocheso, le ho fana ka motlakase o tsitsitseng oa motlakase.Ka kakaretso, baetsi ba li-electrode tsa graphite ba bapala karolo ea bohlokoa ho faneng ka li-electrode tsa boleng bo holimo le ho netefatsa ts'ebetso le ts'epahalo ea ts'ebetso ea indasteri.
