Ukuze kuthintelwe umonakalo we-corrosion obangelwa yi-oxidation ye-flake ye-graphite kwiqondo lokushisa eliphezulu, kuyimfuneko ukufumana into yokubeka isambatho kwizinto eziphezulu zokushisa, ezinokukhusela ngokufanelekileyo i-graphite ye-flake kwi-oxidation kwiqondo lokushisa eliphezulu. Ukufumana olu hlobo lwedyasi ye-flake yegraphite echasene ne-oxidation, kufuneka kuqala sibe neempawu ezifana nokuxhathisa ubushushu obuphezulu, ukubumbana okulungileyo, ukusebenza kakuhle kokuchasana nokuhlwa, isakhono esinamandla sokuchasa i-oxidation kunye nobunzima obuphezulu. Abahleli beFuruite graphite balandelayo babelana ngeendlela zokuthintelaigrafu yeflakeukusuka kwi-oxidized kwiqondo lokushisa eliphezulu:
1. Sebenzisa izinto ezinoxinzelelo lomphunga ngaphantsi kwe-0.1333MPa (1650℃) kunye neempawu ezilungileyo ezibanzi.
2. Khetha izinto zesigaba seglasi ezihlangabezana neemfuno zokusebenza njengezinto zokuzitywina, kwaye uzenze zibe yinto yokutywinwa kwe-crack kwiqondo lokushisa lokusebenza.
3. Ngokomsebenzi womgangatho wamandla asimahla wokuphendula ngeoksijini kunye nobushushu, kwiqondo lobushushu bokwenza intsimbi (1650-1750 ℃), izixhobo ezinobudlelwane obuphezulu neoksijini kune-carbon-oksijeni zikhethwa ukuba zithathe ioksijini kuqala, ukuze ukuba oxidize ngokwabo kunye nokukhuselaigrafu yeflake. Umthamo wesigaba esitsha esiveliswe emva kwe-oxidation sikhulu kuneso sigaba sokuqala, esiluncedo ukuvimba umjelo wangaphakathi we-oksijeni kwaye wenze umqobo we-oxidation.
4. Kwiqondo lokushisa elisebenzayo, inani elikhulu lokufakwa okufana ne-Al2O3, iSiO2 kunye ne-Fe2O3 kwintsimbi etyhidiweyo ingabhengezwa, esabela ngayo ngokwabo kwi-sinter, ukwenzela ukuba ukubandakanywa okuhlukeneyo kwintsimbi etyhidiweyo kungene ngokuthe ngcembe kwi-coating.
I-Furuite graphite isikhumbuza ukuba ubushushu be-oxidation ye-flake graphite kwiindawo eziphambili ze-China ezivelisa i-560815℃ xa umxholo wekhabhoni ungama-88% 96% kunye nobukhulu be-particle bungaphezu kwe-400 mesh. Phakathi kwazo, xa ubungakanani besuntswana legraphite yi-0.0970.105mm, ubushushu be-oxidation yegraphite engaphezulu kwe-90% yekhabhoni umxholo ngu-600815 ℃ kunye ne-graphite engaphantsi kwe-90% yekhabhoni umxholo ngu-62075 ℃. Ikristale ngakumbiigrafu yeflakekukuba, ukuphakama kweqondo lobushushu be-oxidation liphezulu, kwaye ukuncipha kobunzima be-oxidation kubushushu obuphezulu.
