I-graphite iqulethe ukungcola okuthile, ngoko ukulinganisa njani umxholo wekhabhoni kunye nokungcola kwe-flake graphite? Kuba uhlalutyo umkhondo ukungcola kwi-flake yegraphite, isampuli idla ngokuthululwa okanye imanzi igaywe ukuze isuse ikhabhoni, umlotha uchithwa nge-asidi, kwaye umxholo wokungcola kwisisombululo uzimisele. Namhlanje, umhleli weFuruite Graphite uya kukuxelela ukuba ukungcola kwegraphite yeflake kulinganiswa njani:
Indlela yokumisela ukungcola kwegraphite yindlela yokuhlamba umlotha, enenzuzo ethile kunye nobunzima obuthile.
1. Iingenelo zendlela yothuthu.
Indlela ye-ashing ayifuni ukutshabalalisa umlotha kunye ne-ultra-pure acids, ngaloo ndlela igwema ingozi yokwazisa izinto eziza kulinganiswa, ngoko isetyenziswa ngokubanzi.
2. Ubunzima bendlela yothuthu.
Kwakhona kunzima kakhulu ukubhaqa uthuthu lwegraphite, kuba ifuna ukutshiswa kobushushu obuphezulu ukutyebisa uthuthu, kwaye kubushushu obuphezulu, uthuthu luya kunamathela kwisikhephe sesampula kwaye kube nzima ukwahlula, nto leyo ekhokelela ekungakwazini ukumisela ngokuchanekileyo ukubunjwa kunye nomxholo wokungcola. Iindlela ezikhoyo zonke zisebenzisa uphawu lokuba i-platinum crucible ayisebenzi nge-asidi. I-platinum crucible isetyenziselwa ukutshisa i-flake graphite ukutyebisa uthuthu, kwaye isampuli ishushu ngokuthe ngqo nge-asidi kwi-crucible ukunyibilikisa isampuli. Umxholo wokungcola kwi-graphite ye-flake ingabalwa ngokulinganisa amacandelo kwisisombululo. Nangona kunjalo, le ndlela inemida ethile, kuba i-graphite ye-flake iqulethe inani elikhulu lekhabhoni, enokwenza i-platinum crucible brittle kwiqondo lokushisa eliphezulu, iholele ngokulula ukuphuka kwe-platinum crucible, kwaye ixabiso lokufumanisa liphezulu kakhulu, ngoko kunzima ukusetyenziswa ngokubanzi. Ngenxa yokuba indlela yesiqhelo ayikwazi ukubona iinxalenye zokungcola kwe-flake graphite, kuyimfuneko ukuphucula indlela yokubona.
