Nguzogide oxidation nke elektrọd graphite na-adabere na njikọta nke ihe ndị dị na ya, gụnyere okpomọkụ, ntinye oxygen, nhazi kristal, njirimara ihe electrode (dịka ogo graphitization, njupụta buru ibu, na ike mekaniki), nhazi elektrọd (dịka ịdị mma nkwonkwo na ndakọrịta mgbasa okpomọkụ), na ọgwụgwọ elu (dịka mkpuchi antioxidant). Ihe ndị a bụ nyocha zuru ezu nke ihe ndị a:
1, Okpomọkụ:
Ọnụọgụ oxidation nke elektrọd graphite na-abawanye nke ukwuu ka okpomọkụ na-arị elu. N'elu 450°C, graphite na-amalite imeghachi omume nke ọma na oxygen, ọnụego oxidation na-abawanye nke ukwuu mgbe okpomọkụ gafere 750°C.
N'oge okpomọkụ dị elu, mmeghachi omume kemịkalụ dị n'elu graphite na-esiwanye ike, na-eduga na oxidation ngwa ngwa. Dịka ọmụmaatụ, n'ime ọkụ eletriki, okpomọkụ elu elektrọd nwere ike ịgafe 2000°C, na-eme ka oxidation bụrụ isi ihe na-akpata oriri elektrọd.
2. Ntinye Oxygen:
Ngụkọta oxygen bụ ihe dị mkpa na-emetụta ọnụego oxidation nke elektrọd graphite. N'oge okpomọkụ dị elu, mmegharị okpomọkụ nke molekul oxygen na-akawanye njọ, na-eme ka ha nwee ike ịsọ mpi na graphite ma kwalite mmeghachi omume oxidation.
N'ebe ụlọ ọrụ mmepụta ihe dịka ọkụ eletrik, nnukwu ikuku na-abanye site na oghere elektrọd na ọnụ ụzọ ọkụ, na-eweta oxygen ma na-eme ka oxidation elektrọd ka njọ.
3, Nhazi kristal:
Ọdịdị kristal nke graphite dị nro ma nwee ike ịwakpo ya site na atọm oxygen. N'oge okpomọkụ dị elu, nhazi kristal nke graphite na-agbanwekarị, na-eduga na mbelata nkwụsi ike na ngwa ngwa oxidation.
4, Njirimara Ihe Elektrọd:
- Nzere eserese: Electrodes nwere ogo graphitization dị elu na-egosipụta iguzogide oxidation ka mma ma na-ebelata oriri. Graphite dị ọcha nke ukwuu, nke okpomọkụ graphitization na-erukarị ihe dị ka 2800°C, na-egosi iguzogide oxidation dị elu ma e jiri ya tụnyere elektrọd graphite ike nkịtị (nwere okpomọkụ graphitization ihe dị ka 2500°C).
- Njupụta Ukwuu: Ike igwe, modulus na-agbanwe agbanwe, na ike okpomọkụ nke elektrọd graphite na-abawanye ka njupụta ukwu, ebe nguzogide na porosity na-ebelata. Njupụta ukwu nwere mmetụta kpọmkwem na oriri elektrọd, yana elektrọd ndị nwere njupụta buru ibu dị elu na-egosipụta nguzogide oxidation ka mma.
- Ike Mechanical: A na-etinye elektrọd graphite ọ bụghị naanị ibu ha na ike mpụga ha kamakwa nrụgide okpomọkụ tangential, axial, na radial n'oge eji ya. Mgbe nrụgide okpomọkụ gafere ike mechanical nke elektrọd ahụ, mgbawa ma ọ bụ ọbụna mgbawa nwere ike ime. Ya mere, elektrọd nwere ike mechanical dị elu nwere ike iguzogide nrụgide okpomọkụ na iguzogide oxidation ka mma.
5, Nhazi elektrọd:
- Ọdịdị Njikọ: Njikọ bụ ebe adịghị ike nke elektrọd ma na-emebi ihe karịa ahụ elektrọd. Ihe ndị dị ka njikọ dị n'etiti elektrọd na nkwonkwo, na ihe ndị na-eme ka okpomọkụ gbasaa nke ọma nwere ike ibute oxidation ngwa ngwa na ọbụna mgbawa na nkwonkwo.
- Ndakọrịta Mgbasa Okpomọkụ: Njikọta mgbasa okpomọkụ na-adabaghị adaba n'etiti ihe elektrọd na gburugburu ebe obibi nwekwara ike ibute mgbawa elektrọd. Mgbe elektrọd ahụ na-agbasa okpomọkụ n'oge okpomọkụ dị elu, ọ bụrụ na gburugburu ebe obibi ma ọ bụ ihe ndị metụtara elektrọd ahụ enweghị ike ịgbasa nke ọma, njupụta nrụgide na-apụta, nke na-eduga na mgbawa.
6, Ọgwụgwọ Elu:
Ojiji nke ihe mkpuchi antioxidant nwere ike ime ka iguzogide oxidation nke elektrọd graphite dịkwuo mma nke ukwuu. Dịka ọmụmaatụ, mkpuchi antioxidant RLHY-305 graphite na-emepụta mkpuchi antioxidant dị oke njọ n'elu ihe mejupụtara ahụ, na-enye njirimara mkpuchi dị mma. Ọ na-ekewapụ oxygen na graphite na okpomọkụ dị elu, na-egbochi mmeghachi omume dị n'etiti graphite na oxygen, ma na-agbatị ndụ nke ngwaahịa graphite site na opekata mpe 30%.
Ọgwụgwọ itinye ihe n'ime mmiri bụkwa ụzọ dị irè isi gbochie ihe n'ime mmiri. Site n'itinye ihe n'ime mmiri n'ime elektrọd graphite site na iji ihe n'ime mmiri ma ọ bụ mmiri n'ime mmiri eke, enwere ike ime ka iguzogide oxidation nke elektrọd dịkwuo mma.
