Ua cov graphite roj coke (GPC) thiab calcinum coke (CPC)
Pethined Petroleum Coke (CPC): CPC yog tsim los ntawm cua sov roj av roj hmab coke ntawm 1200℃rau hauv ib lub Kiln qeeb lossis lwm cov khoom siv hluav taws xob uas tsim nyog. Cov txheej txheem no, hu ua kev laij tawm, yog tsim los tshem cov tshuaj tsw xws li xws li hydrocarbons, leej faj thiab noo noo, ua rau purer carbon.
Graphite Petroleum Coke (GPC): GPC yog qhov tshwm sim ntawm kev ua haujlwm ntxiv ntawm GPC. Nws cuam tshuam nrog cua sov chp ntawm qhov kub siab heev (feem ntau yog tshaj 2500 degrees) hauv qhov tsis-oxidizing huab cua. Raws li ib tug tshwm sim, carbon atoms tau rov qab mus rau hauv cov qauv crystalline ntawm graphite- Cov txheej txheem no hu ua Graphitization.
Physico -}}}} tshuaj tshuaj ntawm graphite roj coke (GPC) thiab calcinum coke (CPC)
CNC: muaj tsawg hluav taws xob - thiab thermal conductivity thiab kuj tsis sib xws. Txawm hais tias CNC muaj qee tus nqi ntawm cov carbonstalline carbon, nws tsis tsim cov qauv kev txiav txim ntawm HPC.
GPC: Vim tias cov qauv txheej txheem ntxiv ntawm graphite, GPC muaj cov hluav taws xob siab dua {{}} thiab thermal conductivity. Tsis tas li ntawd, nws muaj qhov ntom ntom thiab qis dua coefficient ntawm thermal expansion. Nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab, GPC, raws li txoj cai, yog zoo dua rau GPC.
Daim ntawv thov cov chaw ntawm graphitized roj av coke (GPC) thiab calcinum coke (CPC)
CPC: Siv dav rau electrode ntau lawm hauv cov lag luam steel thiab txhuas; Kuj tseem siv rau kev tsim cov khoom siv titanium dioxide thiab raws li ib tug incandescent hauv cov txheej txheem metallurgical.
GPC: Nws cov physico zoo -}} Cov ntaub ntawv siv tshuaj sib xyaw ua ke, raws li kev lag luam nuclear, nyob rau hauv kev tsim cov khoom siv hluav taws xob siab rau cov hluav taws xob arc.
