I-flake graphite iqulethe ukungcola okuthile, emva koko umxholo we-flake graphite kunye nokungcola yindlela yokuyilinganisa, uhlalutyo lokungcola okuncinci kwi-flake graphite, ngokuqhelekileyo isampuli yenziwa ngaphambi kothuthu okanye ukugaywa okumanzi ukuze kususwe i-carbon, uthuthu lunyibilikiswe nge-asidi, uze emva koko umisele umxholo wokungcola kwisisombululo. Namhlanje siza kukuxelela indlela ukungcola kwe-flake graphite okuchongwa ngayo:
Indlela yokuchonga ubumdaka begrafiti ye-flake yindlela yokutshisa uthuli, enezibonelelo ezithile kunye nobunzima obuthile.
1. iingenelo zendlela yothuthu.
Indlela yokufunxa uthuthu ayidingi kusebenzisa i-asidi ecocekileyo ukunyibilikisa uthuthu, ukuze kuthintelwe umngcipheko wokungenisa izinto eziza kulinganiswa, ukuze isetyenziswe ngakumbi.
2. ubunzima bendlela yothuthu.
Kunzima nokufumanisa umxholo wothuthu lwe-flake graphite, kuba ukutyebisa uthuthu kufuna ukutshiswa kobushushu obuphezulu, kwaye kubushushu obuphezulu uthuthu luya kunamathela kwisikhephe sesampulu kwaye kunzima ukuhlulahlula, nto leyo ekhokelela ekungakwazini ukuchonga ngokuchanekileyo ukwakheka kunye nomxholo wokungcola. Iindlela ezikhoyo zisebenzisa ithuba lokuba i-platinum crucible ayisebenzi ne-asidi, kwaye zisebenzisa i-platinum crucible ukutshisa i-flake graphite ukutyebisa uthuthu, kwaye emva koko zifudumeze isampuli ngokuthe ngqo nge-asidi kwi-crucible ukuze zinyibilikise isampuli, kwaye emva koko zichonge izinto ezikwisisombululo ukuze zibale umxholo wokungcola kwi-flake graphite. Nangona kunjalo, le ndlela inemida ethile, kuba i-flake graphite inekhabhoni eninzi, enokwenza i-platinum crucible ibe buthathaka kwaye ibe buthathaka kubushushu obuphezulu, nto leyo ebangela ukuba i-platinum crucible iqhekeke ngokulula. Ixabiso lokufumanisa liphezulu kakhulu, kwaye kunzima ukuyisebenzisa kakhulu. Ngenxa yokuba ukungcola kwe-flake graphite akunakufunyanwa ngendlela eqhelekileyo, kuyimfuneko ukuphucula indlela yokufumanisa.
