Ukwethulwa kwe-graphite flexible feel
I-graphite yokushisa ephezulu yazizwa inesisindo esilula, ukuphazamiseka okuhle, okuqukethwe kwekhabhoni ephezulu,ukumelana nokushisa okuphezulu, akukho volatilization ekushiseni okuphezulu,ukumelana nokugqwala, encaneconductivity ezishisayonokugcinwa komumo ophezulu.
Umkhiqizo unezinzuzo ezilandelayo: ngemva 1800 ~ 2500 ℃ ukwelashwa izinga lokushisa eliphezulu, umehluko lokushisa phakathi kwanoma iyiphi amaphuzu amabili we wazizwa awukho ngaphezu 50 ℃, ngakho ukusebenza umkhiqizo uzinzile. Ngenxa yokuthi iwukukhiqiza okuqhubekayo, ingaqinisekisa ukufana kwezinto ezizwakalayo kunoma ibuphi ububanzi nobude.
Uma kuqhathaniswa nei-carbon feeliphathwa emazingeni okushisa aphansi (ngaphansi kuka-900 ℃), i-graphite izwakale iphathwa ekushiseni okuphezulu (ngaphezulu kuka-2200 ℃) inezinzuzo ezilandelayo:
(1) I-adsorption yomhwamuko wamanzi namanye amagesi ku-graphite ezwakalayo ingama-oda angu-2 obukhulu obuphansi kunaleyo ekukhabhoni ezwakala iphathwa ngezinga lokushisa eliphansi. Ezisetshenziswa eziningi zemikhumbi evaliwe ezidinga ukugezwa, ukuhlanzeka komkhathi kuyipharamitha ebalulekile. Kodwa-ke, ngenxa yokwenyuka okuphezulu kwekhabhoni ephathwayo enezinga lokushisa eliphansi, kunzima ukucofa umkhumbi.
(2) Umuzwa we-graphite unokumelana ne-thermal oxidation eqinile. Isakhiwo sekhabhoni ngaphandle kwe-graphitization siwuhlobo lwesakhiwo sesendlalelo esiphazamisekile. Ukuba khona kokukhubazeka okuhlukahlukene kwesakhiwo kwenza isikhala sesendlalelo saso sibe sikhulu, futhi kulula ukuhlaselwa ama-athomu omoya-mpilo kanye ne-oxidized. I-lattice ephelele kanye nokuhleleka kwe-graphite okunezinhlangothi ezintathu okuzwakalayo ngemva kokwelashwa kwezinga lokushisa eliphezulu kunciphisa kakhulu isikhala sesendlalelo futhi kwenze kungabi lula ukuhlaselwa ama-athomu omoya-mpilo, ngaleyo ndlela kuthuthukisa kakhulu umthamo we-antioxidant.
(3) Ukuhlanzeka kwe-graphite okuzwakalayo kuphezulu, futhi okuqukethwe kwekhabhoni kungaphezu kuka-99.5%. Okuqukethwe kwekhabhoni kwezinga lokushisa eliphansi lekhabhoni ephathwayo ngokuvamile ingaphansi kwama-93%, okulula ukubangela ukungcoliswa kwemvelo esithandweni.
Ngamafuphi, izinga lokushisa eliphezulu eliphathwe nge-graphite lizwakala linomphumela ongcono nempilo yesevisi ende kunezinga lokushisa eliphansi lekhabhoni elizwakalayo.
