Kuti udzivise kukuvadzwa kwekuora kunokonzerwa neiyo oxidation yeflake graphite pakupisa kwakanyanya, zvinodikanwa kuwana chinhu chekuisa jasi pane yakakwira tembiricha zvinhu, izvo zvinogona kudzivirira zvinobudirira flake graphite kubva kune oxidation pakupisa kwakanyanya. Kuti tiwane rudzi urwu rweflake graphite anti-oxidation jasi, tinofanira kutanga tave nehunhu hwakadai sehupamhi hwekupisa tembiricha, kunaka compactness, yakanaka anti-corrosion performance, yakasimba anti-oxidation kugona uye kuoma kwakanyanya. Inotevera Furuite graphite vapepeti vanogovera nzira dzekudziviriraflake graphitekubva pakuva oxidized pakupisa kwakanyanya:
1. Shandisa zvinhu zvine mhute pressure isingasviki 0.1333MPa(1650 ℃) uye yakanaka yakazara zvivakwa.
2. Sarudza girazi chikamu zvinhu zvinosangana nekuita zvinodiwa sechinhu chekuzvivharira, uye ita kuti ive iyo crack sealing material patembiricha yekushanda.
3. Zvinoenderana nebasa reiyo yakajairwa simba remahara rekuita neokisijeni ine tembiricha, patembiricha yekugadzira simbi (1650-1750 ℃), zvinhu zvine hukama hwepamusoro kune oxygen kupfuura kabhoni-okisijeni zvinosarudzwa kutora oxygen kutanga, kuitira kuti oxidize pachavo uye kudziviriraflake graphite. Huwandu hwechikamu chitsva chinogadzirwa mushure meiyo oxidation yakakura kupfuura iyo yekutanga chikamu, iyo inobatsira kuvhara mukati meiyo diffusion chiteshi cheokisijeni uye kugadzira chinovharira oxidation.
4. Pakushanda kwekushisa, nhamba huru yezvinyorwa zvakadai seAl2O3, SiO2 uye Fe2O3 musimbi yakanyungudutswa inogona kushambadzirwa, iyo inopindirana nayo pachayo kune sinter, kuitira kuti zvinyorwa zvakasiyana-siyana kubva musimbi yakanyungudutswa zvishoma nezvishoma zvipinde mumucheka.
Furuite graphite inotiyeuchidza kuti tembiricha yeoxidation yeflake graphite munzvimbo dzeChina dzinogadzira i560815 ℃ apo kabhoni yemukati iri 88% 96% uye saizi yechidimbu iri pamusoro -400 mesh. Pakati pazvo, kana saizi yegraphite iri 0.0970.105mm, tembiricha yeoxidation yegraphite ine inopfuura 90% kabhoni yemukati i600815 ℃ uye iyo yegraphite ine isingasviki 90% kabhoni yemukati i62075 ℃. Iyo yakawanda crystallineflake graphitendiko, iyo yakanyanya oxidation peak tembiricha iri, uye kushomeka kwehuremu hwehuremu pakupisa kwakanyanya.
