I-Graphite inezinto ezithile ezingacocekanga, ngoko ke ungayilinganisa njani umxholo wekhabhoni kunye nezinto ezingacocekanga ze-flake graphite? Ukuze kuhlalutywe izinto ezingacocekanga ezikwi-flake graphite, isampuli idla ngokugaywa okanye ifunxwe ukuze kususwe i-carbon, uthuthu lunyibilikiswe nge-asidi, emva koko kuchongwe umxholo wokungcola kwisisombululo. Namhlanje, umhleli uFuruite Graphite uza kukuxelela indlela ezilinganiswa ngayo izinto ezingacocekanga ze-flake graphite:
Indlela yokuchonga ubumdaka begrafiti yindlela yokufunxa uthuthu, enezibonelelo ezithile kunye nobunzima obuthile.
1. Iingenelo zendlela yokufunxa uthuthu.
Indlela yokufunxa uthuthu ayidingi kunyibilikisa uthuthu ngee-asidi ezimsulwa kakhulu, ngaloo ndlela ithintela ingozi yokungenisa izinto eziza kulinganiswa, ngoko ke isetyenziswa kakhulu.
2. Ubunzima bokusebenzisa indlela yokufunxa uthuthu.
Kunzima kakhulu ukubona uthuthu lwegrafiti, kuba lufuna ukutshiswa ngobushushu obuphezulu ukuze lutyebise uthuthu, kwaye xa kushushu kakhulu, uthuthu luya kunamathela kwisikhephe sesampulu kwaye kube nzima ukuluhlula, nto leyo ekhokelela ekubeni kungakwazi ukuchonga ngokuchanekileyo ukwakheka kunye nomxholo wokungcola. Iindlela ezikhoyo zonke zisebenzisa uphawu lokuba iplatinum crucible ayisebenzi ne-asidi. Iplatinum crucible isetyenziselwa ukutshisa i-flake graphite ukuze ityebise uthuthu, kwaye emva koko isampuli ifudunyezwa ngokuthe ngqo nge-asidi kwi-crucible ukuze inyibilikise isampuli. Umxholo wokungcola kwi-flake graphite unokubalwa ngokulinganisa izinto ezikwisisombululo. Nangona kunjalo, le ndlela inemida ethile, kuba i-flake graphite inekhabhoni eninzi, enokwenza i-platinum crucible ibe buthathaka kubushushu obuphezulu, ikhokelela ngokulula ekuqhekekeni kwe-platinum crucible, kwaye iindleko zokufumanisa ziphezulu kakhulu, ngoko ke kunzima ukuyisebenzisa kakhulu. Ngenxa yokuba indlela eqhelekileyo ayinakukwazi ukubona izinto zokungcola ze-flake graphite, kuyimfuneko ukuphucula indlela yokufumanisa.
