I-Flake graphite iqulethe ukungcola okuthile, ngoko umxholo wekhabhoni yegraphite kunye nokungcola yindlela yokulinganisa ngayo, uhlalutyo lokulandela ukungcola kwi-flake graphite, ngokuqhelekileyo isampuli i-pre-ash okanye i-wet digestion yokukhupha i-carbon, uthuthu olunyibilike nge-asidi, kwaye emva koko ukugqiba umxholo wokungcola kwisisombululo. Namhlanje siza kukuxelela indlela ukungcola kwe-flake graphite kunqunywe ngayo:
Indlela yokumisela ukungcola kwe-flake yegraphite yindlela yokuhlamba umlotha, enenzuzo ethile kunye nobunzima obuthile.
1. iingenelo indlela ash.
Indlela ye-ashing ayifuni ukusebenzisa i-asidi ecocekileyo ukutshabalalisa umlotha, ukwenzela ukuba ugweme umngcipheko wokwazisa izinto eziza kulinganiswa, ngoko isetyenziswe ngakumbi.
2. ubunzima bendlela yothuthu.
Kwakhona kunzima ukubona umxholo wothuthu lwe-flake yegraphite, ngenxa yokuba ukutyetyiswa kothuthu kufuna ukutshiswa kobushushu obuphezulu, kwaye kwiqondo lokushisa eliphezulu uthuthu luya kunamathela kwisikhephe sesampuli kwaye kunzima ukuhlukana, okukhokelela ekungakwazini ukugqiba ngokuchanekileyo ukubunjwa kunye nomxholo wokungcola. Iindlela ezikhoyo zithatha inzuzo yokuba i-platinum crucible ayisebenzi kunye ne-asidi, kwaye isebenzise i-platinum crucible ukutshisa i-flake graphite ukutyebisa uthuthu, kwaye ishushu ngokuthe ngqo isampuli nge-asidi kwi-crucible ukunyibilika isampuli, kwaye emva koko inqume amacandelo kwisisombululo sokubala umxholo wokungcola kwi-graphite ye-flake. Nangona kunjalo, le ndlela inezithintelo ezithile, kuba i-graphite ye-flake iqulethe inani elikhulu lekhabhoni, enokwenza i-platinum crucible brittle kunye ne-fragile kwiqondo lokushisa eliphezulu, okwenza lula ukuphuka kwe-platinum crucible. Ixabiso lokufumanisa liphezulu kakhulu, kwaye kunzima ukusetyenziswa ngokubanzi. Ngenxa yokuba ukungcola kwe-flake graphite akukwazi ukufunyanwa ngendlela eqhelekileyo, kuyimfuneko ukuphucula indlela yokubona.
