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, isu tinofanira kutanga taramba tembiricha yepamusoro uye compactness.
Yakanaka, yakanaka corrosion resistance, yakasimba oxidation kuramba, kuoma kwepamusoro uye humwe hunhu. Iyo inotevera Furuite Graphite Xiaobian inosuma nzira dzekudzivirira flake graphite kubva pakuiswa oxidized pakupisa kwakanyanya:
1. Shandisa zvinhu zvine mhute pressure isingasviki 0.1333MPa (1650 * C) uye yakanaka yakakwana kuita.
2. Sarudza girazi chikamu zvinhu zvinosangana nekuita zvinodiwa sechinhu chekuzvivharira, uye ita kuti ive iyo crack sealing material patembiricha yekushanda.
3. Zvinoenderana nekushanda kweiyo yakajairwa simba remahara rekuita neokisijeni ine tembiricha, patembiricha yekugadzira simbi (1650-1750 * C), zvinhu zvine hukama hukuru kune oxygen kupfuura kabhoni-okisijeni zvinosarudzwa kuti zvitore okisijeni, saka sekuzviitira oxidize ivo uye kudzivirira iyo flake graphite. Mushure me oxidation, chikamu chitsva chine vhoriyamu reshiyo yechikamu chekutanga chinogadzirwa.
Huru, iyo inobatsira kuvharidzira mukati mekupararira 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.
Oxidation tembiricha yeflake graphite inogadzirwa kuChina i560815°C apo kabhoni iri 88%96% uye saizi yechikamu inodarika mazana mana meshes. Pakati pazvo, kana saizi yegraphite iri 0.0970.105mm, tembiricha yeoxidation yegraphite ine inopfuura 90% kabhoni yemukati i600815 ° C uye kabhoni yemukati iri pasi pe90%.
Iyo oxidation tembiricha yeinki ndeye 620790 C. Izvo zviri nani iyo crystalline flake graphite iri, iyo yakakwirira oxidation peak tembiricha iri, uye zvishoma iyo oxidation uremu kurasikirwa kuri pakupisa kwakanyanya.
