I-Flake graphite iqulethe ukungcola okuthile, ngoko umxholo wekhabhoni yegraphite kunye nobumdaka yindlela yokulinganisa ngayo, uhlalutyo lokungcola komkhondo kwi-flake yegraphite, ngokuqhelekileyo isampuli i-pre-ash okanye i-wet digestion yokususa i-carbon, uthuthu olunyibilike nge-asidi, kwaye emva koko 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, kuba ukutyetyiswa kothuthu kufuna ukutshiswa kobushushu obuphezulu, kwaye kubushushu obuphezulu uthuthu luya kunamathela kwisikhephe isampula kwaye kunzima ukwahlula, nto leyo ekhokelela ekungakwazini ukumisela ngokuchanekileyo ukwakheka kunye nomxholo wokungcola. Iindlela ezikhoyo zithatha ithuba lokuba i-platinum crucible ayisebenzi kunye ne-asidi, kwaye isebenzise i-platinum crucible ukutshisa i-flake graphite ukutyebisa uthuthu, kwaye ifudumeza ngokuthe ngqo isampuli nge-asidi kwi-crucible ukunyibilikisa isampuli, kwaye emva koko. misela amacandelo kwisisombululo ukubala umxholo wokungcola kwigraphite yeflake. 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.
