Ukuze kuthintelwe umonakalo wokugqwala obangelwa yi-oxidation ye-flake graphite kubushushu obuphezulu, kuyimfuneko ukufumana izinto zokugquma izinto ezishushu kakhulu, ezinokukhusela ngempumelelo i-flake graphite kwi-oxidation kubushushu obuphezulu. Ukuze sifumane olu hlobo lwe-scale graphite anti-oxidation coat, kufuneka kuqala sibe neempawu ezithile ezinje ngokumelana nobushushu obuphezulu, ubuncinci obuhle, ukusebenza kakuhle kokulwa nokugqwala, amandla okulwa nokugqwala kunye nobunzima obuphezulu. Umhleli olandelayo we-Furuite Graphite wabelana ngendlela yokuthintela i-flake graphite ukuba igqwale kubushushu obuphezulu:
1. Izixhobo ezinoxinzelelo lomphunga olungaphantsi kwe-0.1333MPa(1650℃) kunye neempawu ezilungileyo ezibanzi ziyasetyenziswa.
2. Khetha izinto zeglasi ezihlangabezana neemfuno zokusebenza njengezinto ezizivala ngokwazo, uze uzenze zibe zizinto ezivala iintanda kubushushu bokusebenza.
3. Ngokwendlela etshintsha ngayo amandla asimahla aqhelekileyo okusabela ngeoksijini enobushushu, kubushushu bokwenza intsimbi (1650-1750℃), khetha izinto ezinamathele kakhulu kwioksijini kuneoksijini yekhabhoni, zibambe ioksijini kuqala, kwaye zizenzele ioksijini ukuze zikhusele igrafiti ye-flake. Umthamo wesigaba esitsha esiveliswa emva kweoksijini mkhulu kunowesigaba sokuqala, nto leyo eluncedo ekuthinteleni umjelo wokusasazwa kweoksijini ngaphakathi kwaye yenze umqobo weoksijini.
4. Kubushushu obusebenzayo, inokufunxa inani elikhulu lezinto ezifakiweyo ezifana ne-AL2O3, i-SiO2, i-Fe2O3 kwintsimbi enyibilikisiweyo, ize iphendule ngokwayo kwi-sinter, ukuze izinto ezahlukeneyo ezifakiweyo ezivela kwintsimbi enyibilikisiweyo zingene kancinci kancinci kwi-coating.
I-Furuite Graphite Xiaobian ikhumbuza ukuba ubushushu be-oxidation ye-flake graphite kwiindawo eziphambili zemveliso zaseTshayina yi-560,815℃ 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 kwama-90% buyi-600,815℃, kwaye obo be-graphite enomxholo wekhabhoni ongaphantsi kwama-90% buyi-6200℃. Okukhona i-crystalline flake graphite ingcono, kokukhona ubushushu be-oxidation peak buphezulu kwaye kokukhona ukulahleka kobunzima be-oxidation kubushushu obuphezulu kuyanda.
