Si looga hortago waxyeelada daxalka ee ay keento oksaydhka graphite flake heerkulka sare, waxaa lagama maarmaan ah in la helo qalab lagu daboolo walxaha heerkulka sare leh, kaas oo si wax ku ool ah uga ilaalin kara graphite flake ka oksaydhka heerkulka sare. Si aad u hesho noocaan miisaanka graphite anti-oxidation jaakad, marka hore waa in aan yeelano qaar ka mid ah sifooyin sida iska caabin heerkulka sare, is haysta wanaagsan, waxqabadka anti-daxalka wanaagsan, awood anti-oxidation xoog leh iyo adkaanta sare. Tifaftiraha soo socda ee Furuite Graphite wuxuu la wadaagaa habka looga hortagayo graphite flake in lagu sameeyo oksidheyn heerkul sare:
1. Qalabka cadaadiska uumiga ka yar yahay 0.1333MPa(1650℃) iyo sifooyin dhamaystiran oo wanaagsan ayaa la qaatay.
2. Dooro walxaha wajiga galaaska ee buuxiya shuruudaha waxqabadka sida walxaha is-xakamaynta, oo ka dhig inay noqdaan sheyga dillaaca ee heerkulka shaqada.
3. Marka loo eego shaqada isbeddelka tamarta bilaashka ah ee falcelinta oksijiinta leh heerkulka, heerkulka birta samaynta (1650-1750 ℃), dooro agabka xidhiidh sare leh oo ogsijiin ka badan carbon-oxygen, marka hore qabtaan ogsijiinta, oo oxidize naftooda si ay u ilaaliyaan. garaafyada jajaban. Mugga wejiga cusub ee la soo saaray ka dib oksaydhisku wuu ka weyn yahay kan wejiga asalka ah, kaas oo waxtar u leh in la xannibo kanaalka faafinta gudaha ee ogsijiinta oo uu sameeyo xannibaadda oksaydhka.
4. Heerkulka shaqada, waxay nuugi kartaa tiro badan oo ka mid ah isku-darka sida AL2O3, SiO2, Fe2O3 ee birta dhalaalaysa, oo waxay la falgashaa lafteeda sinter, si ay kala duwanaansho kala duwan oo ka soo baxa birta dhalaalaysa si tartiib tartiib ah u galaan daahan.
Furuite Graphite Xiaobian waxay xasuusineysaa in heerkulka oksaydhka ee graphite flake ee meelaha ugu muhiimsan ee Shiinaha ee wax soo saarka uu yahay 560,815 ℃ marka maadada kaarboonku ay tahay 88% 96% cabirkuna uu ka sarreeyo -400 mesh. Waxaa ka mid ah, marka cabbirka qayb ka mid ah graphite yahay 0.0970.105mm, heerkulka oksaydhka ee graphite ka badan 90% content carbon waa 600,815 ℃, iyo in graphite ka yar 90% content carbon waa 6200 ℃. Sida wanaagsan ee garaafiga flake crystalline, ayaa sarreeya heerkulka ugu sarreeya oksaydheynta iyo yaraanta miisaanka oksaydhka ee heerkulka sare.
