Kuti udzivise kukuvara kwekuora kunokonzerwa neiyo oxidation yeflake graphite pakupisa kwepamusoro, zvinodikanwa kuwana chinhu chekupfekedza iyo yepamusoro-tembiricha zvinhu, izvo zvinogona kunyatso chengetedza flake graphite kubva kune oxidation pakupisa kwakanyanya. Kuti tiwane rudzi urwu rwechikero che graphite anti-oxidation bhachi, tinofanira kutanga tave nehunhu hwakadai sehupamhi hwekupisa tembiricha, kunaka compactness, yakanaka anti-corrosion performance, yakasimba anti-oxidation kugona uye kuoma kwakanyanya. Inotevera mupepeti weFuruite Graphite anogovera nzira yekudzivirira flake graphite kubva pakuiswa oxidized pakupisa kwakanyanya:
1. Zvishandiso zvine mutsindo wekumanikidza zvisingasviki 0.1333MPa (1650 ℃) uye yakanaka yakazara midziyo inogamuchirwa.
2. Sarudza girazi chikamu zvinhu zvinosangana nekuita zvinodiwa sechinhu chekuzvivharira, uye ita kuti ive iyo crack sealing material mukati metembiricha yekushanda.
3. Zvinoenderana neshanduko yesimba remahara rekuita neokisijeni netembiricha, patembiricha yekugadzira simbi (1650-1750 ℃), sarudza zvinhu zvine hukama hwepamusoro neokisijeni kupfuura kabhoni-okisijeni, tanga watora oxygen, uye oxidize ivo pachavo kuti vadzivirire. flake graphite. Huwandu hwechikamu chitsva chinogadzirwa mushure meiyo oxidation yakakura kupfuura iyo yekutanga chikamu, iyo inobatsira kuvhara mukati meiyo diffusion chiteshi cheokisijeni uye kugadzira iyo oxidation barriers.
4. Pakushanda kwekushisa, inogona kutora nhamba yakawanda yezvinyorwa zvakadai se AL2O3, SiO2, Fe2O3 musimbi yakanyungudutswa, uye inogadzirisa pachayo kune sinter, kuitira kuti zvakasiyana-siyana zvinosanganiswa kubva musimbi yakanyungudutswa zvishoma nezvishoma zvipinde mukuputira.
Furuite Graphite Xiaobian inoyeuchidza kuti tembiricha yeoxidation yeflake graphite munzvimbo dzeChina dzinogadzira i560,815 ℃ 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 i600,815 ℃, uye iyo yegraphite ine isingasviki 90% kabhoni yemukati i6200 ℃. Izvo zvirinani iyo crystalline flake graphite, iyo inokwirisa iyo oxidation yepamusoro tembiricha uye kushomeka kwehuremu hwehuremu pakupisa kwakanyanya.
