Si looga hortago dhaawaca daxalka ee ay keento oksaydhka graphite flake heerkulka sare, waxaa lagama maarmaan ah in la helo shay lagu dhejiyo jaakad ku jirta qalabka heerkulka sare, kaas oo si wax ku ool ah uga ilaalin kara graphite flake ka oksaydhka heerkulka sare. Si aad u heshid jaakad noocaan ah ee garaafiga ah ee ka-hortagga oksaydhka, waa in aan marka hore iska caabinaa heerkulka sare iyo isafgaradka.
Wanaagsan, caabbinta daxalka wanaagsan, iska caabinta oksaydhka xooggan, engegnaanta sare iyo sifooyinka kale. Furuite Graphite Xiaobian ee soo socota waxay soo bandhigaysaa hababka looga hortagayo graphite flake in lagu sameeyo oksidhid heerkulka sare:
1. Isticmaal walxaha cadaadiska uumiga ka yar yahay 0.1333MPa(1650*C) iyo waxqabad dhamaystiran oo wanaagsan.
2. Dooro walxaha wajiga galaaska ee buuxiya shuruudaha waxqabadka sida sheyga is-xakamaynta, oo ka dhig inuu noqdo qalabka wax lagu xiro ee heerkulka shaqada.
3. Marka loo eego shaqada tamarta bilaashka ah ee caadiga ah ee falcelinta oksijiinta leh heerkulka, heerkulka birta-samaynta (1650-1750 * C), walxaha ku xiran oksijiinta ka weyn carbon-oxygen ayaa loo doortaa inay doorbidaan inay qabtaan oksijiinta, sidaas darteed si ay naftooda oksijiyeen oo ay u ilaaliyaan graphite flake. oksaydhaynta ka dib, waji cusub oo leh saamiga mugga ee wajiga asalka ah ayaa la soo saarayaa.
Weyn, kaas oo waxtar u leh inuu xannibo kanaalka faafinta gudaha ee ogsijiinta oo uu sameeyo xannibaad oksaydh ah.
4. Heerkulka shaqada, tiro badan oo ka mid ah inclusions sida Al2O3, SiO2 iyo Fe2O3 ee birta dhalaalaysa waa la adsorbed karaa, kuwaas oo naftooda ula falgala sinter, si inclusions kala duwan ka bir dhalaalaysa si tartiib tartiib ah u galaan daahan.
Heerkulka oksaydhka ee graphite flake ee laga soo saaro Shiinaha waa 560815 ° C marka kaarboonku yahay 88% 96% cabbirkuna uu ka badan yahay 400 meshes. Waxaa ka mid ah, marka cabbirka qayb ka mid ah graphite uu yahay 0.0970.105mm, heerkulka oksaydhka ee graphite oo leh in ka badan 90% kaarboonka waa 600815 ° C iyo kaarboonku waa ka yar yahay 90%.
Heerkulka oksaydhka khadku waa 620790 C. Sida wanaagsan ee garaafiga flake crystalline waa, way sii badanaysaa heerkulka ugu sarreeya ee oksaydhka, iyo yaraanta miisaanka oksaydhku waa heerkul sare.
