Kuti tidzivise kukuvara kwengura kunokonzerwa nekuoxidation kwe flake graphite pakupisa kwakanyanya, zvakakosha kuwana chinhu chekuisa jasi pachinhu chinodziya zvakanyanya, chinogona kudzivirira zvinobudirira flake graphite kubva pakuoxidation pakupisa kwakanyanya. Kuti tiwane rudzi urwu rwe flake graphite anti-oxidation jasi, tinofanira kutanga taramba kupisa kwakanyanya uye kuomarara.
Yakanaka, inodzivirira ngura, inodzivirira kuoxidation yakasimba, kuomarara kwakanyanya nezvimwe zvinhu. Furuite Graphite Xiaobian inotevera inosuma nzira dzekudzivirira flake graphite kuti isaoxidized pakupisa kwakanyanya:
1. Shandisa zvinhu zvine kumanikidzwa kweutsi pasi pe0.1333MPa(1650*C) uye kushanda zvakanaka.
2. Sarudza girazi rinoita sechishandiso chinozvivharira chega, wobva waita kuti chive chinhu chinovhara zvidimbu panguva yekushanda.
3. Zvichienderana nebasa resimba rakasununguka rekuita pamwe chete neokisijeni netembiricha, patembiricha yekugadzira simbi (1650-1750*C), zvinhu zvine hukama hwakakura neokisijeni kupfuura kabhoni-okisijeni zvinosarudzwa kuti zvibate okisijeni, kuitira kuti zvizvioxidize uye zvidzivirire girafiti yeflake. Mushure meokisijeni, chikamu chitsva chine huwandu hwevhoriyamu yechikamu chekutanga chinogadzirwa.
Yakakura, iyo inobatsira kuvharira nzira yekupararira kweokisijeni mukati uye kugadzira chipingamupinyi chekuoxidation.
4. Pakupisa kwekushanda, huwandu hwakawanda hwezvinhu zvakaita seAl2O3, SiO2 uye Fe2O3 musimbi yakanyungudutswa zvinogona kunyungudutswa, izvo zvinosangana nazvo pachazvo kune sinter, kuitira kuti zvinhu zvakasiyana-siyana zvinobva musimbi yakanyungudutswa zvipinde zvishoma nezvishoma mu coating.
Kupisa kwe oxidation ye flake graphite inogadzirwa muChina i560815°C kana kabhoni iri 88%96% uye saizi ye particle iri kupfuura 400 meshes. Pakati pazvo, kana saizi ye particle ye graphite iri 0.0970.105mm, tembiricha ye oxidation ye graphite ine kabhoni inopfuura 90% i600815°C uye kabhoni iri pasi pe90%.
Tembiricha yekuoxidation yeinki ndeye 620790 C. Kana girafiti ye crystalline flake iri nani, tembiricha yepamusoro yekuoxidation inowedzera, uye kudzikira kwehuremu hwekuoxidation kushoma patembiricha yepamusoro.
