I-Graphite iqukethe ukungcola okuthile, ngakho-ke ungalinganisa kanjani okuqukethwe yikhabhoni kanye nokungcola kwe-flake graphite? Ukuze kuhlaziywe ukungcola okumbalwa ku-flake graphite, isampula ivame ukuthululwa noma kugaywe ukuze kususwe i-carbon, umlotha uncibilikiswe ne-asidi, bese kunqunywa okuqukethwe ukungcola okusesixazululweni. Namuhla, umhleli uFuruite Graphite uzokutshela ukuthi ukungcola kwe-flake graphite kulinganiswa kanjani:
Indlela yokunquma ukungcola kwe-graphite yindlela yokuthulula umlotha, enezinzuzo ezithile kanye nobunzima obuthile.
1. Izinzuzo zendlela yokuthulula umlotha.
Indlela yokuthungela umlotha ayidingi ukuncibilikisa umlotha ngama-acid amsulwa kakhulu, ngaleyo ndlela igweme ingozi yokungenisa izakhi ezizolinganiswa, ngakho-ke isetshenziswa kabanzi.
2. Ubunzima bokusebenzisa indlela yokufutha umlotha.
Kunzima kakhulu futhi ukuthola umlotha we-graphite, ngoba udinga ukushiswa ngokushisa okuphezulu ukuze ucebise umlotha, futhi uma izinga lokushisa liphezulu, umlotha uzonamathela esikebheni sesampula futhi kube nzima ukuwuhlukanisa, okuholela ekungakwazini ukunquma ngokunembile ukwakheka nokuqukethwe kokungcola. Izindlela ezikhona zonke zisebenzisa isici sokuthi i-platinum crucible ayisebenzi ne-asidi. I-platinum crucible isetshenziselwa ukushisa i-flake graphite ukuze icebise umlotha, bese isampula ishiswa ngqo nge-asidi ku-crucible ukuze incibilikise isampula. Okuqukethwe kokungcola ku-flake graphite kungabalwa ngokulinganisa izingxenye ezikusisombululo. Kodwa-ke, le ndlela inemikhawulo ethile, ngoba i-flake graphite iqukethe inani elikhulu lekhabhoni, elingenza i-platinum crucible ibe brittle ngokushisa okuphezulu, kuholele kalula ekuqhekekeni kwe-platinum crucible, futhi izindleko zokuthola ziphezulu kakhulu, ngakho-ke kunzima ukuyisebenzisa kabanzi. Ngenxa yokuthi indlela evamile ayikwazi ukuthola izingxenye zokungcola ze-flake graphite, kubalulekile ukuthuthukisa indlela yokuthola.
