Unikani chifukwa chake graphite yowonjezereka imatha kukula, ndipo mfundo yake ndi iti?

Graphite yofutukuka imasankhidwa kuchokera ku graphite yachilengedwe yapamwamba kwambiri ngati zinthu zopangira, yomwe ili ndi mafuta abwino, yolimba kutentha kwambiri, yolimba komanso yolimba chifukwa cha dzimbiri. Pambuyo pofutukuka, mpatawo umakula. Mkonzi wotsatira wa graphite wa Furuite akufotokoza mwatsatanetsatane mfundo yofutukuka ya graphite yofutukuka:
Graphite yowonjezereka ndi njira yomwe imachitika pakati pa graphite yachilengedwe ndi chisakanizo cha nitric acid yowonjezereka ndi sulfuric acid yowonjezereka. Chifukwa cha kulowerera kwa zinthu zatsopano, mankhwala atsopano amapangidwa pakati pa zigawo za graphite, ndipo chifukwa cha kupangidwa kwa chigawochi, zigawo za graphite zachilengedwe zimalekanitsidwa. Pamene graphite yachilengedwe yokhala ndi chigawo cholumikizirana imayikidwa kutentha kwambiri, chigawo cha graphite cholumikizirana chachilengedwe chimasungunuka mofulumira ndi kusungunuka, ndipo mphamvu yokankhira gawolo pakati imakhala yayikulu, kotero kuti nthawi yolumikizirana imakulanso. Kukula kumeneku kumatchedwa expansion yachiwiri, yomwe ndi mfundo ya expansion ya graphite yowonjezereka, yomwe imapanga expansion graphite.
Graphite yokulirapo ili ndi ntchito yotenthetsera komanso kukula mwachangu, ndipo ili ndi ntchito yabwino yothira madzi, kotero imagwiritsidwa ntchito kwambiri mu zomatira zazinthu ndi zinthu zothira madzi zoteteza chilengedwe. Kodi mfundo yothira madzi ya graphite yokulirapo ndi yotani? Ndipotu, ndi kukonzekera njira yothira madzi ya graphite.
