Ukuze kuthintelwe umonakalo wokugqwala obangelwa yi-oxidation ye-flake graphite kubushushu obuphezulu, kuyimfuneko ukufumana izinto zokubeka ijazi kwizinto ezishushu kakhulu, ezinokukhusela ngempumelelo i-flake graphite kwi-oxidation kubushushu obuphezulu. Ukuze sifumane olu hlobo lwe-flake graphite anti-oxidation coat, kufuneka kuqala sibe neempawu ezithile ezinje ngokuxhathisa kubushushu obuphezulu, ukuxinana okuhle, ukusebenza kakuhle kokulwa nokugqwala, amandla okulwa nokugqwala kunye nobunzima obuphezulu. Abahleli be-Furuite graphite balandelayo babelana ngeendlela zokuthintelaigrafayithi ye-flakeekubeni i-oxidized kubushushu obuphezulu:
1. Sebenzisa izixhobo ezinoxinzelelo lomphunga olungaphantsi kwe-0.1333MPa(1650℃) kunye neempawu ezilungileyo ezibanzi.
2. Khetha izinto zeglasi ezihlangabezana neemfuno zokusebenza njengezinto ezizivala ngokwazo, uze uzenze zibe zizinto ezivala iintanda kubushushu bokusebenza.
3. Ngokwendlela esebenza ngayo amandla asimahla aqhelekileyo e-reaction kunye ne-oxygen kunye nobushushu, kubushushu bokwenza intsimbi (1650-1750℃), izixhobo ezinobudlelwane obuphezulu ne-oxygen kune-carbon-oxygen zikhethwa ukuba zithathe i-oxygen kuqala, ukuze zikwazi ukuzinyibilikisa kwaye zikhuseleigrafayithi ye-flakeUmthamo wesigaba esitsha esiveliswa emva kwe-oxidation mkhulu kunowesigaba sokuqala, nto leyo enceda ukuvala umjelo wokusasazwa kweoksijini ngaphakathi kwaye wenze umqobo we-oxidation.
4. Kwiqondo lobushushu lokusebenza, inani elikhulu lezinto ezifakiweyo ezifana ne-Al2O3, i-SiO2 kunye ne-Fe2O3 kwintsimbi enyibilikisiweyo zinokufunxwa, ezisabela ngokwazo kwi-sinter, ukuze izinto ezahlukeneyo ezifakwe kwintsimbi enyibilikisiweyo zingene kancinci kancinci kwi-coating.
I-graphite ye-Furuite isikhumbuza ukuba ubushushu be-oxidation ye-flake graphite kwiindawo eziphambili zemveliso zaseTshayina yi-560815℃ xa umxholo wekhabhoni ungama-88%96% kwaye ubungakanani be-particle bungaphezulu kwe-400 mesh. Phakathi kwazo, xa ubungakanani be-particle ye-graphite buyi-0.0970.105mm, ubushushu be-oxidation ye-graphite enomxholo wekhabhoni ongaphezulu kwe-90% buyi-600815℃ kwaye obo be-graphite enomxholo wekhabhoni ongaphantsi kwe-90% buyi-62075℃. Okukhona i-crystalline ingaphezulu.igrafayithi ye-flakeOkukhona ubushushu be-oxidation peak buphezulu, kwaye kokukhona ukulahleka kobunzima be-oxidation kubushushu obuphezulu kuncinci.
