Kuti tidzivise kukuvara kwengura kunokonzerwa nekuoxidation kweflake graphite pakupisa kwakanyanya, zvakakosha kuwana chinhu chekufukidza zvinhu zvinopisa zvakanyanya, izvo zvinogona kudzivirira zvinobudirira flake graphite kubva pakuoxidation pakupisa kwakanyanya. Kuti tiwane rudzi urwu rwe scale graphite anti-oxidation coat, tinofanira kutanga tava nezvimwe zvinhu zvakaita sekudzivirira kupisa kwakanyanya, kusimba kwakanaka, kushanda zvakanaka kwekudzivirira kuora, kugona kwakasimba kwekudzivirira kuora uye kuomarara kwakanyanya. Mupepeti anotevera weFuruite Graphite anotaura nzira yekudzivirira flake graphite kuti isaoxidized pakupisa kwakanyanya:
1. Zvinhu zvine simba remhepo risingasviki 0.1333MPa(1650℃) uye hunhu hwakanaka hwakazara zvinoshandiswa.
2. Sarudza girazi rinoita sechisimbiso chega, wobva waita kuti chive chinhu chinovhara zvidimbu mukati mekupisa kwekushanda.
3. Zvichienderana nebasa rekuchinja kwesimba rakasununguka rekuita pamwe chete neokisijeni netembiricha, patembiricha yekugadzira simbi (1650-1750℃), sarudza zvinhu zvine hukama hwakanyanya neokisijeni kupfuura kabhoni-okisijeni, tanga wabata okisijeni, wozvioxida kuti udzivirire girafiti yeganda. Huwandu hwechikamu chitsva chinogadzirwa mushure mekuoxidation hwakakura kupfuura hwechikamu chekutanga, izvo zvinobatsira kuvharira nzira yekupararira kweokisijeni mukati uye kugadzira chipingamupinyi chekuoxidation.
4. Pakupisa kwekushanda, inogona kupinza huwandu hwakawanda hwezvinhu zvakaita seAL2O3,SiO2,Fe2O3 musimbi yakanyungudutswa, uye yoita zvinoenderana nechinhu chinopenya, zvekuti zvinhu zvakasiyana-siyana zvinobva musimbi yakanyungudutswa zvinopinda zvishoma nezvishoma mujira.
Furuite Graphite Xiaobian anoyeuchidza kuti tembiricha yekuoxidation yeflake graphite munzvimbo huru dzekugadzira dzeChina i560,815℃ kana kabhoni iri 88%96% uye saizi yeparticle iri pamusoro pe -400 mesh. Pakati pavo, kana saizi yeparticle yegraphite iri 0.0970.105mm, tembiricha yekuoxidation yegraphite ine kabhoni inopfuura 90% iri 600,815℃, uye yegraphite ine kabhoni isingasviki 90% iri 6200℃. Kana crystalline flake graphite iri nani, tembiricha yekuoxidation peak inowedzera uye kurasikirwa kwehuremu hweoxidation kushoma pakupisa kwakanyanya.
