I-flake graphite iqukethe ukungcola okuthile, bese kuthi okuqukethwe yi-flake graphite carbon kanye nokungcola kuyindlela yokukulinganisa, ukuhlaziywa kokungcola okumbalwa ku-flake graphite, ngokuvamile isampula isuke ingaphambi komlotha noma ihlanzwe ngamanzi ukuze kususwe i-carbon, umlotha uncibilikiswe ne-asidi, bese kunqunywa okuqukethwe kokungcola esixazululweni. Namuhla sizokutshela ukuthi kunqunywa kanjani ukungcola kwe-flake graphite:
Indlela yokunquma ukungcola kwe-graphite ye-flake yindlela yoku-ashing, enezinzuzo ezithile kanye nobunzima obuthile.
1. izinzuzo zendlela yomlotha.
Indlela yokuthungela umlotha ayidingi ukusebenzisa i-asidi emsulwa ukuncibilikisa umlotha, ukuze kugwenywe ingozi yokungenisa izinto ezizolinganiswa, ngakho-ke isetshenziswa kakhulu.
2. ubunzima bendlela yomlotha.
Kunzima futhi ukuthola okuqukethwe komlotha we-flake graphite, ngoba ukunothiswa komlotha kudinga ukushisa okuphezulu, futhi ekushiseni okuphezulu umlotha uzonamathela esikebheni sesampula futhi kunzima ukuwuhlukanisa, okuholela ekungakwazini ukunquma ngokunembile ukwakheka nokuqukethwe kokungcola. Izindlela ezikhona zisebenzisa iqiniso lokuthi i-platinum crucible ayisebenzi ne-asidi, bese zisebenzisa i-platinum crucible ukushisa i-flake graphite ukunothisa umlotha, bese zishisa isampula ngqo nge-asidi ku-crucible ukuncibilikisa isampula, bese zinquma izingxenye ezikusisombululo sokubala okuqukethwe kokungcola ku-flake graphite. Kodwa-ke, le ndlela inemingcele ethile, ngoba i-flake graphite iqukethe inani elikhulu lekhabhoni, okungenza i-platinum crucible ibe buthakathaka futhi ibe buthakathaka ekushiseni okuphezulu, okubangela kalula ukuqhekeka kwe-platinum crucible. Izindleko zokuthola ziphezulu kakhulu, futhi kunzima ukusetshenziswa kabanzi. Ngenxa yokuthi ukungcola kwe-flake graphite akunakutholakala ngendlela evamile, kubalulekile ukuthuthukisa indlela yokuthola.
