Habka looga hortagayo graphite flake in uu oksidhid ku jiro heerkulka sare

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 hesho jaakad noocaan ah ee graphite flake anti-oxidation, waa in aan marka hore yeelano astaamo ay ka mid yihiin iska caabbinta heerkulka sare, isafgaradka wanaagsan, waxqabadka ka hortagga daxalka, awooda adag ee ka hortagga oksaydhka iyo qallafsanaanta sare. Tafatirayaasha garaafyada Furuite ee soo socda waxay wadaagaan hababka looga hortagogaraafyada jajabanlaga bilaabo oksidized heerkulka sare:

1. Isticmaal walxaha leh cadaadiska uumiga ka yar 0.1333MPa(1650℃) iyo sifooyin 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 ℃), walxaha ku xiran oksijiin ka sarreeya carbon-oxygen ayaa loo xushay inay qaataan oksijiinta marka hore, si si ay naftooda oksijiyeen oo ay u ilaaliyaangaraafyada jajaban. Mugga wejiga cusub ee la soo saaray ka dib oksaydhisku wuu ka weyn yahay kan wejigii hore, kaas oo waxtar u leh in la 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.

Garaafiga Furuite wuxuu ina xasuusinayaa in heerkulka oksaydhka ee graphite flake ee meelaha wax soo saarka ugu weyn ee Shiinaha uu yahay 560815 ℃ marka maadada kaarboonku tahay 88% 96% cabirkuna uu ka sarreeyo -400 mesh. iyaga ka mid ah, marka size qayb ka mid ah graphite waa 0.0970.105mm, heerkulka oksaydhka ee graphite ka badan 90% content carbon waa 600815 ℃ iyo in graphite ka yar 90% content carbon waa 62075 ℃. Inta badan crystallinegaraafyada jajabanwaa, mar kasta oo heerkulka ugu sarreeya oksaydhisku yahay, iyo yaraanta miisaanka luminta oksaydhka heerkulka sare waa.
