Kodi graphite yowonjezera imapangidwa bwanji?

graphite yowonjezerandi mtundu watsopano wa zinchito carbon zakuthupi, amene ndi lotayirira ndi porous nyongolotsi ngati mankhwala anapezedwa zachilengedwe flake graphite pambuyo intercalation, kutsuka, kuyanika ndi mkulu kutentha kukula. Mkonzi wotsatira wa Furuite Graphite akuwonetsa momwe graphite yowonjezera imapangidwira:

Chifukwa graphite ndi zinthu zopanda polar, zimakhala zovuta kulumikiza ndi ma asidi ang'onoang'ono a polar kapena ma inorganic acid okha, choncho nthawi zambiri pamafunika kugwiritsa ntchito okosijeni. Nthawi zambiri, njira yopangira makutidwe ndi okosijeni ndiyo kuviika ma flake graphite mu njira ya okosijeni ndi intercalation agent. Pansi pa zochita za oxidant wamphamvu, graphite ndi oxidized, zomwe zimapangitsa ndale maukonde planar macromolecules mu graphite wosanjikiza kukhala zabwino mlandu macromolecules planar. Chifukwa cha kutulutsa kwazinthu zabwino pakati pa ma macromolecules opangidwa bwino, mipata pakatigraphitezigawo kumawonjezeka, ndi intercalation wothandizira anaikapo pakati pa zigawo graphite kukhala kukodzedwa graphite.
Ma graphite owonjezera amachepa mwachangu akatenthedwa kutentha kwambiri, ndipo kuchuluka kwa shrinkage kumakhala kokwera kufika makumi mpaka mazana kapenanso nthawi zikwizikwi. Voliyumu yowoneka bwino ya shrinkage graphite imafika 250 ~ 300ml/g kapena kupitilira apo. Kuchepa kwa graphite kumakhala ngati nyongolotsi, ndi kukula kwa 0.1 mpaka mamilimita angapo. Ili ndi mawonekedwe a reticular micropore omwe amapezeka mu nyenyezi zazikulu. Amatchedwa graphite worm kapena graphite worm ndipo ali ndi zinthu zambiri zapadera.
Kuwonjezedwa graphite ndi graphite expandable angagwiritsidwe ntchito zitsulo, zitsulo, mafuta, makina makina, Azamlengalenga, mphamvu ya atomiki ndi magawo ena mafakitale, ndipo ntchito zosiyanasiyana zake ndizofala kwambiri.graphite yowonjezeraopangidwa ndi Furuite graphite angagwiritsidwe ntchito ngati choletsa lawi lawi lawi lawilo ndi zinthu zomwe zimayaka moto, monga zinthu zapulasitiki zoletsa moto komanso zokutira zoletsa moto.
