Yakawedzerwa graphiterudzi rutsva rwekushanda kabhoni zvinhu, inova yakasununguka uye ine porous honye-yakafanana nechinhu chinowanikwa kubva kune yakasikwa flake graphite mushure mekupindirana, kuwacha, kuomesa uye kuwedzera tembiricha. Mupepeti anotevera weFuruite Graphite anosuma kuti yakawedzerwa sei graphite inogadzirwa:
Nekuti graphite isiri polar material, zvinonetsa kupindirana nediki polar organic kana inorganic acids chete, saka kazhinji zvinodikanwa kushandisa oxidants. Kazhinji, iyo kemikari oxidation nzira ndeyekunyudza yakasikwa flake graphite mumhinduro ye oxidant uye intercalation agent. Pasi pechiito cheoxidant yakasimba, graphite inoiswa oxidized, izvo zvinoita kuti neutral network planar macromolecules mu graphite layer ive yakanaka charged planar macromolecules. Nekuda kweiyo extrusion mhedzisiro yemachaji akanaka pakati peanochaja planar macromolecules, nzvimbo iri pakati.graphitezvidimbu zvinowedzera, uye mumiririri wekubatanidza anoiswa pakati pemagrafu kuti ave girafu yakawedzerwa.
Yakawedzerwa graphite inodzikira nekukurumidza kana ichipisa pakupisa kwakanyanya, uye shrinkage yakawanda yakakwira semakumi kusvika kumazana kana kunyange zviuru zvenguva. Iyo inooneka vhoriyamu ye shrinkage graphite inosvika 250 ~ 300ml/g kana kupfuura. graphite iri kuderera yakaita sehonye, ine saizi ye 0.1 kusvika mamirimita akati wandei. Iine reticular micropore chimiro chinowanikwa mune nyeredzi huru. Inonzi shrinking graphite kana graphite worm uye ine zvakawanda zvakakosha zvemhando yepamusoro.
Yakawedzerwa graphite uye girafu rayo rinowedzera rinogona kushandiswa musimbi, simbi, petroleum, makemikari muchina, aerospace, simba reatomu uye mamwe maindasitiri maindasitiri, uye huwandu hwayo hwekushandisa hwakajairika.Yakawedzerwa graphiteinogadzirwa neFuruite graphite inogona kushandiswa senge inodzoreredza murazvo wemoto unodzoreredza macomposites uye zvigadzirwa, senge-zvinomisa moto zvigadzirwa zvepurasitiki uye zvinodzivirira moto antistatic coatings.
