ʻO ka coke calcined "Under-burned", ma muli o ka lawa ʻole o ka calcination o ka mea maka, e alakaʻi i nā hemahema kūkulu kūloko i ka wā o ka graphitization ma hope, kahi e hoʻoulu ai i nā hemahema hiki ʻole ke hoʻihoʻi ʻia e like me nā māwae, ka nui like ʻole, ka emi ʻana o ka nui maʻamau, a me ka hōʻino ʻana o ka hana i nā huahana graphitized. Eia kahi loiloi kikoʻī:
Ka hopena pololei o ka lawa ʻole o ka calcination o nā mea maka
He hana koʻikoʻi ka calcination ma mua o ka graphitization, e manaʻo ana e ʻae i nā mea volatile i loko o nā mea maka (e like me ka petroleum coke a me ka nila coke) e pakele ma o ka mālama ʻana i ka mahana kiʻekiʻe, e hōʻemi ana i ka nui o ka haumia, a me ka hana ʻana i kahi ʻano pore kūpono. Inā lawa ʻole ka calcination (ʻo ia hoʻi, "under-burned"), e waiho ana kahi nui o nā mea volatile a me nā haumia i hana ʻole ʻia i loko o nā mea maka. E hoʻomau kēia mau koena i ka palaho a i ʻole ka hopena i ka wā o ka graphitization ma hope, e hoʻoulu ai i ka pakele ʻana o ke kinoea a i ʻole nā loli kemika i loko o nā huahana, a laila e alakaʻi ai i nā hemahema kūkulu.
Nā hemahema hiki ʻole ke hoʻihoʻi ʻia i hana ʻia i ka wā o ka Graphitization
Nā hemahema māwae:
- Kumu Hoʻokumu: ʻO nā mea hoʻoheheʻe a me nā haumia i koe i loko o ka coke calcined i puhi ʻole ʻia e pala koke a pane paha ma lalo o nā mahana kiʻekiʻe o ka graphitization, e hana ana i ka nui o ke kinoea. Hōʻiliʻili kēia kinoea i loko o ka huahana a ʻimi i nā ala pakele; inā ʻaʻole hiki ke kipaku ʻia i ka manawa kūpono, hana ia i ke kaomi kiʻekiʻe i loko o ka huahana, e alakaʻi ana i ka hoʻokumu ʻana o ka māwae. Eia kekahi, ʻo ke ʻano pore like ʻole o ka coke calcined i puhi ʻole ʻia e hiki ke hopena i ka hoʻolaha ʻana o ke kaumaha wela i ka wā o ka graphitization, e hoʻonui hou aku i ka hoʻokumu ʻana o ka māwae.
- Hopena: Hoʻemi nā māwae i ka ikaika mechanical a me ka conductivity uila o ka huahana a hiki ke hana iā ia e haki i ka wā o ka hana ʻana a i ʻole ka hoʻohana ʻana ma hope.
Ka nui like ʻole:
- Kumu Hoʻokumu: ʻO ke ʻano like ʻole o nā pore o ka coke calcined i puhi ʻole ʻia e alakaʻi ai i ka neʻe ʻana o nā mea like ʻole a me ka densification i ka wā o ka graphitization. Hiki i kekahi mau wahi ke ʻike i ka lawa ʻole o ka densification ma muli o nā pores nui, aʻo kekahi poʻe e hoʻomohala i nā ʻano stress ma muli o ka over-densification.
- Hopena: Hoʻopilikia ka mānoanoa like ʻole i nā ʻōkuhi hana koʻikoʻi o ka huahana, e like me ka conductivity uila, ka conductivity wela, a me ka ikaika mechanical.
Ka emi ʻana o ka leo maʻamau ʻole:
- Kumu Hoʻokumu: Hiki i ka coke calcined i puhi ʻole ʻia ke emi iki ka nui i ka wā o ka graphitization ma muli o ka decomposition o nā mea volatile i koe a i ʻole ka hopena o nā haumia. Hiki i kēia emi ʻana maʻamau ke hopena i nā ana huahana paʻa ʻole a me ke ʻano deformation.
- Hopena: Hoʻopilikia ka emi ʻana o ka nui maʻamau i ka pololei o ka dimensional a me ka hana hōʻuluʻulu o ka huahana, e hōʻemi ana i kona ʻano holoʻokoʻa.
Ka Hoʻohaʻahaʻa ʻana o ka Hana:
- Kumu Hoʻokumu: Ma muli o ke alo o nā kīnā i ʻōlelo ʻia ma luna, ʻo nā huahana graphitized i hana ʻia mai ka coke calcined i puhi ʻole ʻia e hōʻike i ka conductivity uila haʻahaʻa, ka conductivity thermal, a me ka ikaika mechanical i hoʻohālikelike ʻia me nā mea i hana ʻia mai ka coke calcined pono.
- Hopena: Hoʻopaʻa ka hōʻino ʻana o ka hana i ka laulā o ka noi a me ke ola lawelawe o ka huahana, e hōʻemi ana i kona hoʻokūkū ma ka mākeke.
