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 siqale simelane nobushushu obuphezulu kunye nokuxinana.
Ukumelana nokugqwala okuhle, ukumelana nokugqwala okunamandla, ubulukhuni obuphezulu kunye nezinye iimpawu. I-Furuite Graphite Xiaobian ilandelayo yazisa iindlela zokuthintela i-flake graphite ukuba ingagqwali kubushushu obuphezulu:
1. Sebenzisa izixhobo ezinoxinzelelo lomphunga olungaphantsi kwe-0.1333MPa(1650*C) kunye nokusebenza kakuhle okubanzi.
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*C), izinto ezinamathele kakhulu kwi-oxygen kune-carbon-oxygen zikhethwa ukuze zibambe i-oxygen ngokukhethekileyo, ukuze zikwazi ukuzinyibilikisa kwaye zikhusele i-flake graphite. Emva kwe-oxidation, kuveliswa isigaba esitsha esine-volume ratio yesigaba sokuqala.
Inkulu, enceda ukuvala umjelo wokusasazwa kweoksijini ngaphakathi kwaye yenze umqobo wokuxinana.
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.
Ubushushu be-oxidation ye-flake graphite eveliswa eTshayina yi-560815°C xa umxholo wekhabhoni ungama-88%96% kwaye ubungakanani be-particle bungaphezulu kwama-400 meshes. Phakathi kwazo, xa ubungakanani be-particle ye-graphite buyi-0.0970.105mm, ubushushu be-oxidation ye-graphite enomxholo wekhabhoni ongaphezulu kwama-90% yi-600815°C kwaye umxholo wekhabhoni ungaphantsi kwama-90%.
Ubushushu be-oxidation ye-inki yi-620790 C. Okukhona i-crystalline flake graphite ingcono, kokukhona i-oxidation peak iphezulu, kwaye kokukhona i-oxidation weight loss incinci xa iphantsi kobushushu obuphezulu.
