Ukuze kuthintelwe umonakalo we-corrosion obangelwa yi-oxidation ye-flake ye-graphite kwiqondo lokushisa eliphezulu, kuyimfuneko ukufumana izinto zokugubungela ubushushu obuphezulu, obunokukhusela ngokufanelekileyo i-graphite ye-flake kwi-oxidation kwiqondo lokushisa eliphezulu. Ukufumana olu hlobo lwedyasi 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. Umhleli olandelayo we-Furuite Graphite wabelana ngendlela yokuthintela i-flake graphite ekubeni i-oxidized kubushushu obuphezulu:
1. Izinto eziphathekayo ezinoxinzelelo lwe-steam ngaphantsi kwe-0.1333MPa (1650 ℃) kunye neempawu ezintle ezibanzi zamkelwe.
2. Khetha izinto zesigaba seglasi ezihlangabezana neemfuno zokusebenza njengezinto zokuzitywina, kwaye uzenze zibe yinto yokutywinwa kokuqhekeka ngaphakathi kobushushu bokusebenza.
3. Ngokomsebenzi otshintshileyo wamandla asimahla wokuphendula ngeoksijini ngeqondo lobushushu, kwiqondo lobushushu bokwenza intsimbi (1650-1750℃), khetha izinto ezinobudlelwane obuphezulu neoksijini kune-carbon-oksijeni, bamba ioksijini kuqala, kwaye bazigcine ngokwabo ukuze bazikhusele. igrafu 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, liyakwazi ukufunxa inani elikhulu lezinto ezifakiweyo ezifana ne-AL2O3, iSiO2, i-Fe2O3 kwintsimbi etyhidiweyo, kwaye iphendule ngokwayo kwi-sinter, ukwenzela ukuba ukubandakanywa okuhlukeneyo kwintsimbi etyhidiweyo kungene ngokuthe ngcembe kwi-coating.
I-Furuite Graphite Xiaobian ikhumbuza ukuba ubushushu be-oxidation ye-flake graphite kwiindawo eziphambili ze-China zokuvelisa yi-560,815 ℃ xa umxholo wekhabhoni ungama-88% 96% kunye nobukhulu be-particle bungaphezu kwe-400 mesh. Phakathi kwazo, xa ubukhulu besuntswana legraphite yi-0.0970.105mm, ubushushu be-oxidation yegraphite engaphezulu kwe-90% yesiqulatho sekhabhoni yi-600,815 ℃, kwaye leyo yegraphite engaphantsi kwe-90% yekhabhoni umxholo ngu-6200℃. Okukhona icrystalline flake graphite ingcono, kokukhona iphezulu iqondo lobushushu be-oxidation kwaye kokukhona ukuncipha kobunzima be-oxidation kubushushu obuphezulu.
