Inqubo yokukhiqiza ama-electrode e-graphite iyinqubo eyinkimbinkimbi futhi ecophelelayo ehilela izinyathelo eziningi ezibalulekile, ngasinye sithonya kakhulu ikhwalithi kanye nokusebenza komkhiqizo wokugcina. Nazi izinyathelo ezibalulekile enqubweni yokukhiqiza ama-electrode e-graphite:
Ukukhethwa Kwezinto Eziluhlaza Nokwelashwa Kwangaphambi Kokwelashwa:
- Ukukhethwa Kwezinto Eziluhlaza: Izinto eziyinhloko zokusetshenziswa kwama-electrode e-graphite zifaka phakathi i-petroleum coke, i-needle coke, kanye ne-coal tar pitch. I-petroleum coke, etholakala ekuqoqweni kwe-petroleum residue kanye ne-asphalt, inokuqukethwe okuphansi komlotha; i-needle coke, ebonakala ngokuthungwa kwayo okune-fibrous kanye ne-coefficient ephansi yokwanda kokushisa, ibalulekile ekukhiqizeni ama-electrode e-graphite anamandla aphezulu noma aphezulu kakhulu; i-coal tar pitch isebenza njengesihlanganisi.
- Ukwelashwa Kwangaphambi Kokwelashwa: Izinto zokusetshenziswa zifakwa ku-calcination ukuze kususwe umswakama nezinto ezishintshashintshayo, okuthuthukisa izakhiwo zazo ze-physicochemical. Izinga lokushisa le-calcination ngokuvamile lilawulwa phakathi kuka-1250-1350°C ukuqinisekisa ukuthi izinto zokusetshenziswa zihlangabezana nezindinganiso zekhwalithi ephezulu.
Ukuchoboza, Ukugaya, Nokuhlola:
Izinto zokusetshenziswa ezifakwe i-calcium ziyachotshozwa, zigaywe, bese zihlungwa ukuze kutholakale izinhlayiya zamathambo kanye nempuphu enobukhulu bezinhlayiya ezifunekayo. Lesi sinyathelo sibalulekile ezinqubweni ezilandelayo zokuxuba nokuxuba, ukuqinisekisa ukufana kanye nokuvumelana kwezinto zokusetshenziswa.
Ukuhlanganisa Nokuxuba:
- Ukuhlanganisa: Ngokusekelwe ezidingweni zomkhiqizo, izinto zokusetshenziswa ezikhethiwe zixutshwa ngezilinganiso ezithile ukuze kufezwe ukusebenza okufiselekayo. Ukulinganisa nokulawula okunembile ngesikhathi sokuxuba kubalulekile ukuqinisekisa ikhwalithi ehambisanayo kumkhiqizo wokugcina.
- Ukuxuba: Izinto zokusetshenziswa ezihlanganisiwe zixutshwa kahle bese zixovwa ukuze kwakhiwe ingxube efanayo. Izinga lokushisa nesikhathi kulawulwa ngesikhathi sokuxuba ukuqinisekisa ukuxuba okufanele kanye nokuqina okufiselekayo kwezinto zokusetshenziswa.
Ukubumba:
Izinto ezixovwe zicindezelwa ukuze kwakhiwe isimo sokuqala se-graphite electrode. Ukulawulwa okunembile kwengcindezi kanye nokushisa ngesikhathi sokubumba kuyadingeka ukuqinisekisa ukunemba komumo nobukhulu bomkhiqizo. Izindlela zokubumba zifaka phakathi ukucindezela ngodayi, ukukhipha, kanye nokubumba ngokudlidliza, okukhethwa ngokusekelwe kuhlobo lomkhiqizo kanye nemininingwane.
Ukubhaka:
I-electrode ye-graphite ebunjiwe idlula ekushiseni okuphezulu ukuze kuqiniswe isakhiwo sayo. Ngesikhathi sokubhaka, i-coal tar pitch emzimbeni oluhlaza iyagobhoza, ikhiphe ama-volatiles ngenkathi ibhekene nokuncipha kwevolumu kanye nokulahlekelwa isisindo. I-electrode ebhakiwe ibonisa izakhiwo ze-physicochemical ezithuthukisiwe kakhulu, njengokuncipha kobuningi, ukwehla kokumelana kukagesi, kanye namandla emishini athuthukisiwe.
Ukufuthwa (Ongakukhetha):
Kuma-electrode anezidingo eziphezulu zobuningi, ukwelashwa kokufakwa kuyadingeka. Ukufakwa kuhlose ukunciphisa ukugoba komkhiqizo, ukwandisa ubuningi bawo kanye namandla omshini, kanye nokuthuthukisa ukuhanjiswa kwawo kagesi nokushisa. Amapharamitha afana nokushisa kwangaphambi kokushisa, isikhathi se-vacuum, izinga lokushisa lokufakwa kwe-asphalt, kanye nengcindezi kulawulwa ngesikhathi sokufakwa.
Ukuhlelwa kwe-graphitization:
I-electrode iphathwa emazingeni okushisa aphezulu kakhulu ukuze kuguqulwe isakhiwo sezinto zekhabhoni sibe yisakhiwo sekristalu ye-graphite, okuthuthukisa ukuqhutshwa kwayo kukagesi kanye nokumelana nokushisa. Izinga lokushisa nesikhathi kulawulwa ngesikhathi se-graphitization ukuqinisekisa ukuthi i-electrode ifinyelela izinga elifunekayo le-graphitization. I-electrode ene-graphitized ikhombisa ukumelana kukagesi okuncishisiwe kakhulu kanye nokuqhutshwa kwayo okuthuthukisiwe kakhulu.
Umshini:
I-electrode ene-graphised idlula ekusetshenzisweni kwemishini, okuhlanganisa ukubhoboza, ukujika, ukuqeda ubuso bokugcina, ukugaywa kwentambo, kanye nezinyathelo ezifana nokusika, ukufulela ubuso bokugcina, ukujika okuthambile, kanye nokubhoboza izixhumi. Ukulawulwa okuqinile kokunemba komshini kanye nekhwalithi yobuso kuyadingeka ngesikhathi somshini ukuqinisekisa ukunemba nokusebenza kobukhulu be-electrode.
Ukuhlolwa Nokupakisha:
I-electrode eseqediwe ihlolwa ngokuphelele, okuhlanganisa nemingcele efana nokunemba, isisindo, ubude, ububanzi, ubuningi be-bulk, ukumelana nogesi, kanye nokunemba kokulingana ngaphambi kokuhlanganiswa. Ngemva kokudlula ekuhlolweni, i-electrode ipakishwa ukuze ithuthwe futhi igcinwe.
