Eminyakeni yamuva nje, ubuchwepheshe bokukhiqiza obusekhayaama-graphite ama-brucIbleswenze inqubekela phambili enkulu. Hhayi nje ukuthi babambe ama-earribles angenisiwe, kepha kwezinye izikhathi badlula nabo. Ngokusebenzisa amasu okukhiqiza amasha kanye nokuthola izinto zokusetshenziswa ezisezingeni eliphakeme kakhulu, ama-graphite ama-grup
Izici eziphambili zalezi zincuqeni ezintsha ze-graphite ngokungangabazeki zikufanele ukubonwa. Okokuqala, banokuvuselelwa okuphezulu okushisayo, ukunciphisa kakhulu isikhathi esincibilikayo, ngenxa yokusetshenziswa kwezinto ezingavuthiwe njenge-graphite, enokwenza okuhle kakhulu okushisayo. Lokhu kwanda ekusebenzeni kahle hhayi kuphela ukusindisa isikhathi namandla, kepha futhi kukhulisa umkhiqizo kuzo zonke izimboni.
Ngaphezu kwalokho, lezi zinwele zinokumelana kahle nokushisa okuhle kakhulu futhi zikwazi ukumelana namazinga okushisa aze afike ku-1200 kuya ku-1600 ° C. Leli khwalithi elihlukile lenza lilungele izinhlelo zokusebenza ezidinga amazinga okushisa aphezulu, njengokuphonswa kwensimbi kanye nabatholakele. Amandla okumelana namazinga okushisa athe xaxa ngaphandle kokuyekethisa ukusebenza kungumguquki wegeyimu wezinqubo eziningi zezimboni.
Enye yezinto eziphawuleka kakhulu kwalezi zinzulu ze-graphite ukumelana nakho okuhle kakhulu kokugqwala. Bakhombisa ukumelana okukhulu ngisho nalapho ebhekene nezinto zokwehla kwezimbumbulu ezilimazayo, kuqinisekise ukusebenza isikhathi eside nokusebenza okuthuthukisiwe. Lokhu kumelana nokukhulisa kunwebisa uhla lwezicelo zalezi zincuphe, ikakhulukazi kwizimboni zamakhemikhali nezensimbi.
Ngaphezu kwalokho, ukumelana kwaso okuphezulu okuphezulu kwe-thermal kwenza kube mkhulu kunemikhiqizo efanayo. Ama-graphite ama-brucibles akhombisa ukuqina ngaphansi kokupholisa okusheshayo kanye nokushisa imijikelezo, kubenza bacashile ekuqhekekeni nasekuqhekekeni. Lokhu kuqina okuphezulu akuveli kuphela ukuphepha kodwa futhi kuhlinzeka ngezindleko ezibalulekile ngokonga isidingo sokufakwa kabusha kwezidingo njalo.
Ama-graphite ama-brucibles asetshenziswa kabanzi emikhakhelweni ehlukahlukene ngenxa yokuvuselelwa okungcono kakhulu okushisayo kanye nokumelana okushisa okuphezulu. Lezi zinwele zinenhlanzeko ephansi yokwanda okushisayo futhi amelana nezinguquko ezingazelelwe ekushiseni. Bangamelana nokushisa okusheshayo nokupholisa ngaphandle kokuhlupheka kakhulu, baqinisekise ukusebenza okuhle nokwethembeka.
Ama-graphite ama-brucibles anokumelana nokugqwayiza okuyisibonelo ezixazululweni ze-acidic ne-alkali, ezibenza zibalulekile ezindaweni zokusebenzela kanye nezitshalo zokukhiqiza amakhemikhali. Ukuqina kwabo okuhle kokuphendula kwamakhemikhali kukhombisa ukuqina kwabo futhi kungaphatha ngokuphepha amakhemikhali ahlukahlukene.
Ukwakheka kwegraphiti ebekwe emvelo kuyinto yemvelo ye-flake njengezinto eziphambili ezingavuthiwe. Kubanjwa ndawonye kusetshenziswa ukunamathela okukhethekile okubizwa ngamalahle emicibishini yepulasitiki. Le nhlanganisela eyingqayizivele iqinisekisa ukuthi ama-graphite ama-bruckible agcina ubuqotho besakhiwo ngaphansi kwezimo ezinzima, ukuhlinzeka ngemiphumela engaguquki ezinhlobonhlobo zezicelo.
Ukuqala kokukhiqizwa kwe-graphite okukhiqizwe ngaphambi kwesikhathi akugcini nje kumaphawula ukuphumelela kwezobuchwepheshe kuphela, kodwa futhi kusekela ukuthuthukiswa kwezimboni zasendaweni. I-Permin Okwenziwayo, i-Curicibles ephezulu yekhwalithi yehlisa ukuthembela ekungenisweni ngenkathi ihlinzeka ngamanani ancintisanayo ahlukahlukene amabhizinisi. Le ntuthuko ivula indlela yokwanela okukhulu futhi iqinise indawo yezimboni yezwe.
Ngamafuphi, izinto ezintsha ku-graphite ukukhiqizwa okusebenzayo zikuqhubekele ekuphakameni okusha, kudlula imikhiqizo efanayo engenisiwe ngokuya ngokusebenza nokuqina. Ukuvuselelwa okuhle kakhulu okushisayo, ukumelana okungcono kakhulu kokushisa okuhle, ukumelana nokugqwala nokumelana nokushaqeka okushisayo kwenza kube yinto ebaluleke kakhulu ezinhlotsheni ezahlukahlukene zezimboni. Ngalezi zithuthuka, imboni ye-graphite yasekhaya ebekhona yenze iminikelo ebalulekile ekukhuleni kwezimboni zezwe nokuzethemba.
