Flake graphite ya ƙunshi wasu ƙazanta, sa'an nan flake graphite carbon abun ciki da ƙazanta ne yadda za a auna shi, da bincike na gano najasa a flake graphite, yawanci samfurin ne pre-ash ko rigar narkewa don cire carbon, toka narkar da acid, sa'an nan sanin abun ciki na impurities a cikin bayani. Yau za mu gaya muku yadda ƙazantar flake graphite aka ƙaddara:
Hanyar ƙayyadaddun ƙazanta na graphite shine hanyar toka, wanda yana da wasu fa'idodi da wasu matsaloli.
1. amfanin hanyar toka.
Hanyar toka ba ta buƙatar amfani da acid mai tsafta don narkar da toka, don guje wa haɗarin gabatar da abubuwan da za a auna, don haka ana amfani da shi sosai.
2. wahalar hanyar toka.
Har ila yau, yana da wuya a gano abin da ke cikin ash na graphite na flake, saboda wadatar ash yana buƙatar ƙona zafin jiki mai zafi, kuma a babban zafin jiki ash zai tsaya ga jirgin ruwan samfurin kuma yana da wuya a rabu, wanda ke haifar da rashin iyawa don ƙayyade ainihin abun da ke ciki da abubuwan da ba su da kyau. Hanyoyin da ake amfani da su suna amfani da gaskiyar cewa platinum crucible ba ya amsa da acid, kuma suna amfani da platinum crucible don ƙone flake graphite don wadatar da ash, sa'an nan kuma kai tsaye zafi samfurin tare da acid a cikin crucible don narkar da samfurin, sa'an nan kuma ƙayyade abubuwan da ke cikin maganin don ƙididdige abubuwan da ba su da kyau a cikin flake graphite. Duk da haka, wannan hanya tana da wasu ƙuntatawa, saboda flake graphite yana dauke da adadi mai yawa na carbon, wanda zai iya sa platinum crucible gaggautsa da rashin ƙarfi a yanayin zafi, cikin sauƙi yana haifar da fashewar platinum crucible. Kudin ganowa yana da yawa, kuma yana da wahala a yi amfani da shi sosai. Saboda ƙazantattun graphite na flake ba za a iya gano su ta hanyar al'ada ba, yana da mahimmanci don inganta hanyar ganowa.
