Tawm tsam keeb kwm yav dhau los ntawm kev nthuav dav thoob ntiaj teb cov hlau, txhuas electrolysis, thiab kev lag luam hluav taws xob tshiab, kev xaiv cov pa roj carbon additives tau dhau los ua qhov tseem ceeb hauv kev txiav txim siab cov khoom lag luam zoo, kev tswj hwm tus nqi, thiab kev ua haujlwm zoo. Raws li ob qho kev lag luam carbon cov ntaub ntawv tseem ceeb -calcined petroleum coke (CPC) thiab graphite petroleum coke (GPC)-txawm hais tias sib koom tib cov ntaub ntawv raw, lawv sib txawv hauv cov txheej txheem ntau lawm, ntsuas kev ua tau zoo, thiab daim ntawv thov scenarios. Koj tuaj yeem ua qhov kev xaiv zoo tshaj plaws rau koj daim ntawv thov li cas? Kab lus no muab ib qho hauv - tsom xam qhov tob los ntawm ntau qhov kev xav.
Tib Raw Khoom, Cov txheej txheem sib txawv
Calcined petroleum coke yog cov khoom siv carbon tau los ntawm calcining roj av coke ntawm kwv yees li 1300 degree. Nws yog dav siv hauv graphite electrodes, aluminium electrolysis anode paste, thiab kev lag luam metallurgical. Nws txoj kev npaj yog feem ntau ua nyob rau hauv ib tug teb kiln los yog lub lauj kaub rauv ntawm 1200℃mus rau 1500 degree, ib tug txheej txheem uas tshem tawm volatiles, nce taag carbon cov ntsiab lus, thiab txhim kho cov qauv crystallinity.
Graphite petroleum coke, ntawm qhov tod tes, koom nrog ntxiv graphitizing calcined petroleum coke nyob rau hauv ib qho ultra- kub kub siab tshaj 3000℃. Cov txheej txheem no rearranges carbon atoms rau hauv ib qho kev txiav txim siab graphite siv lead ua qauv, txo cov sulfur thiab nitrogen cov ntsiab lus thiab txhim kho conductivity thiab thermal shock resistance. Los ntawm refining residue mus rau siab -tus nqi- ntxiv cov ntaub ntawv, graphitized petroleum coke tau dhau los ua "rov qab los."
Application Scenarios: Txhua tus nrog nws tus kheej lub zog
Cov ntawv thov CPC feem ntau yog tsom rau hauv kev lag luam hnyav hnyav. Nws yog cov khoom siv tseem ceeb rau carbon anodes hauv aluminium electrolysis, nrog aluminium smelting yog nws thawj qhov chaw noj. Tsis tas li ntawd, CPC muaj kev siv dav hauv kev tsim cov hluav taws xob zoo tib yam graphite electrodes, steel carbonization, thiab ua roj hauv cov cement thiab fais fab kev lag luam.
GPC daim ntawv thov nthuav tawm ob qho tib si ib txwm thiab cov haujlwm tshiab. Hauv kev lag luam steel, GPC yog ib qho tseem ceeb raw khoom rau ultra- siab zog graphite electrodes thiab nyiam carbonizer nyob rau hauv smelting ntawm ductile hlau thiab tsawg- sulfur tshwj xeeb steels. Hauv kev lag luam hluav taws xob tshiab, GPC, nrog nws cov ultra- tsis muaj sulfur, siab purity, thiab zoo heev conductivity, tau dhau los ua ib qho tseem ceeb precursor rau lithium - ion roj teeb anode cov ntaub ntawv. Tib lub sijhawm, GPC tseem tuav txoj haujlwm tsis tuaj yeem hloov pauv hauv siab -kawg daim ntawv thov xws li txhuas electrolysis cathodes, carbon txhuam, thiab nuclear graphite.
Xaiv cov khoom zoo: Sib piv cov kev xav tau thiab nkag siab txog tus nqi tag nrho
Kev txiav txim siab xaiv cov khoom lag luam yuav tsum muaj kev txiav txim siab zoo ntawm peb qhov: cov khoom yuav tsum tau ua kom zoo, cov txheej txheem txheej txheem, thiab cov qauv nqi.
- Graphite Petroleum Coke (GPC) yog tsim rau:
Ua high-kawg metallurgical khoom xws li ultra- siab zog graphite electrodes, ductile hlau, thiab qis- sulfur tshwj xeeb hlau;
Lithium{0}} ion roj teeb anode cov ntaub ntawv thiab cov ntawv thov hauv lub zog tshiab;
Daim ntawv thov Scenery nrog nruj ib puag ncig lossis kev xav tau zoo rau cov ntsiab lus sulfur thiab kev tswj tsis huv;
Cov ntawv thov nrhiav cov pa roj carbon ntau dua kom txo lub sijhawm smelting thiab txhim kho kev ua haujlwm tag nrho.
- Calcinated Petroleum Coke (CPC) yog tsim rau:
Ib txwm teb xws li lub zog zoo tib yam graphite electrodes thiab txhuas electrolysis carbon anodes;
Tus nqi -sensitive steel carbon uptake thiab casting ntau lawm nrog rau cov kev xav tau zoo;
Scenery daim ntaub ntawv nrog siab ruaj cov ntsiab lus ntawm cov pa roj carbon monoxide tab sis kuj so kom txaus rau impurities xws li sulfur thiab nitrogen.
Nws yuav tsum raug sau tseg tias txawm hais tias tus nqi ntawm GPC feem ntau yog siab dua li ntawm CPC, los ntawm qhov kev xav ntawm tag nrho cov nqi siv, nws tus nqi nce siab dua, lub sij hawm smelting luv dua, thiab cov khoom ruaj khov dua feem ntau ua rau lub sij hawm zoo dua - kev lag luam. Qhov no kuj yog ib qho laj thawj tseem ceeb vim li cas ntau lub tuam txhab foundry thiab steelmaking tau maj mam hloov mus rau graphitized carbon additives nyob rau xyoo tas los no. Cov tuam txhab lag luam yuav tsum ua tiav ntsuas lawv tus kheej cov yam ntxwv ntawm cov txheej txheem, cov khoom muag, thiab cov hom phiaj tus nqi los ua qhov kev xaiv zoo.
Nyob rau hauv lub ntiaj teb no nthwv dej ntawm ntsuab ntsuab thiab txhim kho nyob rau hauv kev tsim, kev xaiv ntawm carbon additives tsis yog ib tug teeb meem ntawm tus nqi, tab sis kuj zoo, efficiency, thiab kev sib tw. Nkag siab txog qhov sib txawv ntawm cov calcined petroleum coke thiab graphitized petroleum coke yog qhov tseem ceeb heev kom tau txais kev sib tw hauv kev sib tw ua lag luam hnyav zuj zus.
