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 lwengubo ye-flake yegraphite echasene ne-oxidation, kufuneka siqale sixhathise ubushushu obuphezulu kunye nokubumbana.
Okulungileyo, ukuxhathisa okulungileyo kwe-corrosion, ukuxhathisa okuqinileyo kwe-oxidation, ubunzima obuphezulu kunye nezinye iimpawu. Le ilandelayo iFuruite Graphite Xiaobian yazisa iindlela zokuthintela i-flake graphite ekubeni ifakwe i-oxid kubushushu obuphezulu:
1. Sebenzisa izinto ezinoxinzelelo lomphunga ngaphantsi kwe-0.1333MPa (1650 * C) kunye nokusebenza kakuhle okubanzi.
2. Khetha izinto zesigaba seglasi ezihlangabezana neemfuno zokusebenza njengezinto zokuzitywina, kwaye uzenze zibe yinto yokutywinwa kwe-crack kwiqondo lokushisa lokusebenza.
3. Ngokomsebenzi womgangatho oqhelekileyo wamandla wokuphendula nge-oksijini kunye nobushushu, kwiqondo lokushisa le-steelmaking (1650-1750 * C), izinto ezihambelana kakhulu ne-oksijeni kune-carbon-oksijeni zikhethwa ukuba zibambe i-oksijini, ngoko ke. njengokwenza i-oxidize ngokwabo kunye nokukhusela i-graphite ye-flake. Emva kwe-oxidation, isigaba esitsha esinomlinganiselo womthamo wesigaba sokuqala senziwa.
Enkulu, eluncedo ekuthinteleni umjelo wangaphakathi wokusasazwa kweoksijini 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.
Ubushushu be-oxidation ye-flake ye-graphite eveliswe e-China yi-560815 ° C xa umxholo wekhabhoni ungama-88% 96% kwaye ubungakanani be-particle bungaphezu kwama-400 meshes. Phakathi kwabo, xa ubukhulu be-particle ye-graphite yi-0.0970.105mm, ukushisa kwe-oxidation ye-graphite engaphezulu kwe-90% ye-carbon content yi-600815 ° C kunye ne-carbon content ngaphantsi kwe-90%.
Ubushushu be-oxidation ye-inki yi-620790 C. Ingcono i-crystalline flake graphite, iphezulu i-oxidation iqondo lokushisa, kwaye ngaphantsi kwe-oxidation ilahleko yobunzima kubushushu obuphezulu.
