Graphite ya flake imakhala ndi zinthu zina zosafunika, kenako graphite ya flake imakhala ndi zinthu zosafunika komanso zosafunika monga momwe tingaziyezere, kusanthula kwa zinthu zosafunikira mu graphite ya flake, nthawi zambiri chitsanzocho chimaphikidwa musanadye phulusa kapena kunyowa kuti muchotse kaboni, phulusa limasungunuka ndi asidi, kenako n’kupeza zinthu zosafunika mu yankho. Lero tikukuuzani momwe kusayera kwa graphite ya flake kumadziwidwira:
Njira yodziwira zinyalala za graphite ndi njira yochotsera phulusa, yomwe ili ndi ubwino ndi zovuta zina.
1. ubwino wa njira yothira phulusa.
Njira yothira phulusa siifunika kugwiritsa ntchito asidi woyera kuti isungunule phulusa, kuti ipewe chiopsezo choyambitsa zinthu zomwe ziyenera kuyezedwa, kotero imagwiritsidwa ntchito kwambiri.
2. Kuvuta kwa njira yopangira phulusa.
N'kovutanso kuzindikira kuchuluka kwa phulusa mu flake graphite, chifukwa kuwonjezera phulusa kumafuna kutentha kwambiri, ndipo kutentha kwambiri phulusa limamatira ku boti la chitsanzo ndipo n'kovuta kulekanitsa, zomwe zimapangitsa kuti munthu asathe kudziwa bwino kapangidwe ndi kuchuluka kwa zinyalala. Njira zomwe zilipo zimagwiritsa ntchito mwayi woti platinum crucible sichita ndi asidi, ndipo imagwiritsa ntchito platinum crucible kutentha flake graphite kuti iwonjezere phulusa, kenako itenthetse chitsanzocho ndi asidi mu flake crucible kuti isungunuke chitsanzocho, kenako idziwe zigawo zomwe zili mu yankho kuti iwerengere kuchuluka kwa zinyalala mu flake graphite. Komabe, njira iyi ili ndi zoletsa zina, chifukwa flake graphite ili ndi carbon yambiri, yomwe ingapangitse platinum crucible kukhala yofooka komanso yofooka kutentha kwambiri, zomwe zimapangitsa kuti platinum crucible isweke mosavuta. Mtengo wozindikira ndi wokwera kwambiri, ndipo n'kovuta kugwiritsa ntchito kwambiri. Chifukwa zinyalala za flake graphite sizingadziwike ndi njira yachikhalidwe, ndikofunikira kukonza njira yodziwira.
