Gịnị bụ graphitization?
Graphitization bụ usoro mmepụta ihe nke a na-atụgharị carbon ka ọ bụrụ graphite.Nke a bụ mgbanwe microstructure nke na-eme na carbon ma ọ bụ nchara dị ala ekpughere na okpomọkụ nke 425 ruo 550 degrees Celsius ruo ogologo oge, kwuo 1,000 awa.Nke a bụ ụdị mgbakasị ahụ.Dịka ọmụmaatụ, microstructure nke carbon-molybdenum steels na-enwekarị pearlite (ngwakọta nke ferrite na cementite).Mgbe a na-esepụta ihe ahụ, ọ na-eme ka pearlite ahụ ghọọ ferrite na graphite gbasasịrị na-enweghị usoro.Nke a na-ebute mgbakasị nchara na mbelata ike dị ala mgbe a na-ekesa ụmụ irighiri ihe eserese ndị a na-enweghị usoro na matriks.Otú ọ dị, anyị nwere ike igbochi graphitization site n'iji ihe ndị nwere nguzogide dị elu nke na-enwechaghị mmetụta nke graphitization.Na mgbakwunye, anyị nwere ike gbanwee gburugburu ebe obibi, dịka ọmụmaatụ, ịbawanye pH ma ọ bụ ibelata ọdịnaya chloride.Ụzọ ọzọ iji gbochie graphitization gụnyere iji mkpuchi.Nchekwa Cathodic nke nkedo ígwè.
Kedu ihe bụ carbonization?
Carbonization bụ usoro mmepụta ihe nke a na-atụgharị ihe ndị dị ndụ na carbon.Ihe organic anyị na-atụle ebe a gụnyere ozu osisi na anụmanụ.Usoro a na-eme site na-ebibi ihe.Nke a bụ mmeghachi omume pyrolytic ma a na-ewere ya dị ka usoro mgbagwoju anya nke enwere ike ịhụ ọtụtụ mmeghachi omume kemịkal n'otu oge.Dị ka ọmụmaatụ, dehydrogenation, condensation, hydrogen nyefe na isomerization.Usoro carbonization dị iche na usoro carbonization n'ihi na carbonization bụ usoro ngwa ngwa n'ihi na ọ na-emeghachi ọtụtụ iwu nke ịdị ukwuu ngwa ngwa.N'ozuzu, oke ọkụ nke etinyere nwere ike ịchịkwa ogo carbonization na ọnụọgụ nke ihe ndị mba ọzọ fọdụrụ.Dịka ọmụmaatụ, ọdịnaya carbon nke ihe fọdụrụ bụ ihe dịka 90% site na ịdị arọ na 1200K na ihe dịka 99% site na ịdị arọ na ihe dịka 1600K.N'ozuzu, carbonization bụ mmeghachi omume exothermic, nke enwere ike ịhapụ onwe ya ma ọ bụ jiri ya mee ihe dị ka isi iyi ike na-enweghị ịmepụta ọ bụla nke carbon dioxide gas.Otú ọ dị, ọ bụrụ na ekpughere ihe ndị na-emepụta ihe na-ahụ maka mgbanwe mberede na okpomọkụ (dị ka mgbawa nuklia), ihe ndị na-emepụta ihe ga-eme ka carbonize ngwa ngwa o kwere mee ma ghọọ carbon siri ike.

Kedu ihe dị iche n'etiti graphitization na carbonization?
Graphitization na carbonization bụ usoro mmepụta ihe abụọ.Isi ihe dị iche n'etiti carbonization na graphitization bụ na carbonization gụnyere ịtụgharị organic okwu ka carbon, ebe graphitization gụnyere ịtụgharị carbon na graphite.Ya mere, carbonization bụ mgbanwe kemịkalụ, ebe graphitization bụ mgbanwe microstructure.
