Ukumelana nokushiswa kwe-oxidation kwama-electrode e-graphite kuthonywa yinhlanganisela yezici, okuhlanganisa izinga lokushisa, ukuhlushwa kwe-oxygen, isakhiwo sekristalu, izakhiwo zezinto ze-electrode (njengezinga le-graphitization, ubuningi be-bulk, kanye namandla omshini), ukwakheka kwe-electrode (njengekhwalithi yokuhlangana kanye nokuhambisana kokushisa), kanye nokwelashwa kwendawo (njengezimbozo ze-antioxidant). Okulandelayo ukuhlaziywa okuningiliziwe kwalezi zici:
1, Izinga Lokushisa:
Izinga lokushiswa kwama-electrode e-graphite likhuphuka kakhulu lapho izinga lokushisa likhuphuka. Ngaphezu kuka-450°C, i-graphite iqala ukusabela ngamandla nomoya-mpilo, futhi izinga lokushiswa likhuphuka kakhulu lapho izinga lokushisa lidlula u-750°C.
Emazingeni okushisa aphezulu, ukusabela kwamakhemikhali ebusweni be-graphite kuba namandla kakhulu, okuholela ekushiseni kwe-oxidation. Isibonelo, ezithandweni zikagesi ze-arc, izinga lokushisa lobuso be-electrode lingadlula u-2000°C, okwenza i-oxidation ibe yimbangela eyinhloko yokusetshenziswa kwe-electrode.
2, Ukuhlushwa kwe-Oxygen:
Ukuhlushwa kwe-oksijini kuyisici esibalulekile esithinta izinga lokushiswa kwama-electrode e-graphite. Emazingeni okushisa aphezulu, ukunyakaza kokushisa kwama-molecule e-oxygen kuyaqina, okwenza kube lula ukuthi ashayisane ne-graphite futhi kukhuthaze ukusabela kwe-oxidation.
Ezindaweni zezimboni ezifana nezitofu zikagesi, umoya omningi ungena ngezimbobo ze-electrode ezimboza isithando somlilo kanye neminyango yesithando somlilo, okuletha umoya-mpilo futhi kwandise ukuminyana kwe-electrode.
3, Isakhiwo sekristalu:
Isakhiwo sekristalu se-graphite sikhululekile futhi sisengozini yokuhlaselwa ama-athomu e-oxygen. Emazingeni okushisa aphezulu, isakhiwo sekristalu se-graphite sivame ukushintsha, okuholela ekunciphiseni ukuzinza kanye nokusheshisa i-oxidation.
4, Izakhiwo Zezinto Ze-Electrode:
- Izinga Lokubamba I-Graphitization: Ama-electrode anezinga eliphezulu lokubamba i-graphitization abonisa ukumelana okungcono kokushisa kanye nokusetshenziswa okuphansi. I-graphite ehlanzekile kakhulu, enezinga lokushisa lokubamba i-graphitization elivame ukufika cishe ku-2800°C, ibonisa ukumelana okuphezulu kokushisa kokushisa uma kuqhathaniswa nama-electrode avamile e-graphite power (anezinga lokushisa lokubamba i-graphitization elicishe libe ngu-2500°C).
- Ubuningi Bobuningi: Amandla okusebenza, i-modulus enwebekayo, kanye nokuqhuba ukushisa kwama-electrode e-graphite kuyanda ngobuningi bobuningi, kuyilapho ukumelana nokuqina kanye ne-porosity kwehla. Ubuningi bobuningi bunomthelela oqondile ekusetshenzisweni kwama-electrode, lapho ama-electrode anobukhulu obukhulu obuphezulu ebonisa ukumelana okungcono kwe-oxidation.
- Amandla Okusebenza: Ama-electrode e-graphite awagcini nje ngokucindezeleka kwesisindo sawo namandla angaphandle kodwa futhi abhekene nokucindezeleka kokushisa okubonakalayo, okuqondile, kanye nokuqondile ngesikhathi sokusetshenziswa. Lapho ukucindezeleka kokushisa kudlula amandla okusebenza e-electrode, kungase kube nokuqhekeka noma ngisho nokuqhekeka. Ngakho-ke, ama-electrode anamandla aphezulu okusebenza anokumelana okunamandla nokucindezeleka kokushisa kanye nokumelana okungcono kwe-oxidation.
5, Umklamo we-Electrode:
- Ikhwalithi Yokuhlangana: Amajoyinti ayizindawo ezibuthakathaka zama-electrode futhi asengozini enkulu yokulimala kunomzimba we-electrode. Izici ezifana nokuxhumana okuxekethile phakathi kwama-electrode namajoyinti, kanye nama-coefficients okwanda kokushisa angalingani kungaholela ekushiseni okusheshayo kanye nokuqhekeka kwamalunga.
- Ukuhambisana Kokwanda Kokushisa: Ama-coefficient okwanda kokushisa angalingani phakathi kwezinto ze-electrode nendawo ezungezile nakho kungabangela ukuqhekeka kwe-electrode. Lapho i-electrode idlula ekukhuleni kokushisa emazingeni okushisa aphezulu, uma indawo ezungezile noma izinto ezithinta i-electrode zingakwazi ukwanda ngokufanele, ukugxila kokucindezeleka kwenzeka, ekugcineni kuholele ekuqhekekeni.
6, Ukwelashwa Kobuso:
Ukusetshenziswa kwezimbozo ze-antioxidant kungathuthukisa kakhulu ukumelana kwe-oxidation kwama-electrode e-graphite. Isibonelo, i-RLHY-305 graphite antioxidant coating yakha imbozo ye-antioxidant eningi ebusweni be-substrate, inikeza izakhiwo ezinhle kakhulu zokuvala. Ihlukanisa umoya-mpilo ku-graphite emazingeni okushisa aphezulu, ivimbele ukusabela phakathi kwe-graphite nomoya-mpilo, futhi yandise isikhathi sokuphila kwemikhiqizo ye-graphite okungenani ngo-30%.
Ukwelashwa ngokufaka ama-antioxidant nakho kuyindlela ephumelelayo yokulwa nama-antioxidant. Ngokufaka ama-antioxidants kuma-electrode e-graphite ngokufaka ama-vacuum noma ngokucwilisa ngokwemvelo, ukumelana nokuphuma kwama-electrode kungathuthukiswa.
