I-Flake graphite iqukethe ukungcola okuthile, bese i-flake graphite carbon okuqukethwe nokungcola kuyikala kanjani, ukuhlaziywa kokulandelwa kokungcola ku-flake graphite, imvamisa isampula lingaphambi komlotha noma ukugaya okumanzi ukukhipha ikhabhoni, umlotha oncibilikiswe nge-asidi, bese kunqunywa okuqukethwe ukungcola kusisombululo. Namuhla sizokutshela ukuthi ukungcola kwe-flake graphite kunqunywa kanjani:
Indlela yokuzimisela kokungcola kwe-graphite ukungcola kuyindlela yomlotha, enezinzuzo ezithile nobunzima obuthile.
1. izinzuzo zendlela yomlotha.
Indlela ye-Ashing ayidingi ukusebenzisa i-asidi emsulwa ukuncibilikisa umlotha, ukuze kugwemeke ubungozi bokwethula izinto ezizolinganiswa, ngakho-ke isetshenziswa kakhulu.
2. ubunzima bendlela yomlotha.
Kunzima futhi ukuthola okuqukethwe komlotha we-flake graphite, ngoba ukunothisa umlotha kudinga ukushisa okuphezulu, futhi emazingeni aphezulu okushisa umlotha uzonamathela esikebheni sesampula futhi kunzima ukuhlukanisa, okuholela ekuhlulekeni ukunquma ngokunembile ukwakheka nokuqukethwe kokungcola. Izindlela ezikhona zisizakala ngeqiniso lokuthi i-platinum crucible ayisebenzi nge-asidi, futhi isebenzisa i-platinum crucible ukushisa i-flake graphite ukuze ithuthukise umlotha, bese ishisa ngqo isampula nge-asidi ku-crucible ukuze ichithe isampula, bese nquma izinto ezisesisombululo sokubala okuqukethwe kokungcola ku-flake graphite. Kodwa-ke, le ndlela inezingqinamba ezithile, ngoba i-flake graphite iqukethe inani elikhulu lekhabhoni, elingenza i-platinum crucible ibe brittle futhi ibe ntekenteke emazingeni aphezulu okushisa, okwenza kube lula ukudilika kweplatinum crucible. Izindleko zokuthola ziphakeme kakhulu, futhi kunzima ukusetshenziswa kabanzi. Ngoba ukungcola kwe-flake graphite akukwazi ukutholwa ngendlela ejwayelekile, kuyadingeka ukwenza ngcono indlela yokuthola.
