Hauv qab no yog cov ncauj lus kom ntxaws sib piv ntawm ob:
1. Khoom siv
Tooj Electrodes: Ua los ntawm tooj liab hlau, uas yog cov khoom siv zoo heev thiab malleable.
Graphite electrodes: Feem ntau ntawm cov pa roj carbon monoxide, muab tau los ntawm roj av coke thiab thee tar pitch, ua tiav rau hauv cov qauv graphitic.
2. Hluav taws xob conductivity
Tooj Electrodes: Muaj hluav taws xob conductivity siab heev, yog ib qhov siab tshaj plaws ntawm cov hlau, ua rau lawv zoo heev rau cov ntawv thov uas yuav tsum tau muaj hluav taws xob tsawg.
Graphite electrodes: Muaj cov khoom siv hluav taws xob zoo tab sis feem ntau qis dua cov tooj liab. Lawv conductivity yog txaus rau ntau high-temperature thiab industrial daim ntaub ntawv.
3. Thermal conductivity
Tooj Electrodes: Muaj cov thermal conductivity zoo heev, uas tso cai rau kom muaj cua sov thiab txias hauv kev siv xws li EDM (Electrical Discharge Machining).
Graphite electrodes: Kuj muaj cov thermal conductivity zoo, tab sis lawv cov kev ua tau zoo tuaj yeem sib txawv raws li hom thiab zoo. Graphite tuaj yeem tiv taus qhov kub thiab txias zoo dua li tooj liab yam tsis muaj melting.
4. Thermal stability
Tooj Electrodes: Muaj qhov chaw melting ntawm kwv yees li 1,984 degree F (1,085 degree ). Lawv tuaj yeem deform lossis yaj thaum ua haujlwm hauv qhov chaw kub kub heev.
Graphite electrodes: tuaj yeem tiv taus qhov kub thiab txias ntau dua (txog li 5,400 degree F lossis 3,000 degree ) yam tsis muaj melting, ua rau lawv haum rau kev siv xws li hluav taws xob arc rauv.
5. Tshuaj tiv thaiv
Tooj Electrodes: Muaj peev xwm corrode thaum raug rau tej yam tshuaj los yog ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv siab kub. Lawv tuaj yeem oxidize thaum muaj oxygen.
Graphite electrodes: Feem ntau pom muaj kev ruaj ntseg zoo thiab tsis kam tiv thaiv cov tshuaj tiv thaiv, tshwj xeeb tshaj yog nyob rau hauv kev txo qis ib puag ncig. Txawm li cas los xij, graphite tuaj yeem oxidize ntawm qhov kub thiab txias thaum muaj oxygen.
6. Nqi thiab Muaj
Tooj Electrodes: Feem ntau kim dua graphite electrodes vim tus nqi ntawm cov tooj liab nyoos thiab kev lag luam hloov pauv. Lawv qhov muaj tuaj yeem sib txawv raws li kev ua lag luam.
Graphite electrodes: Feem ntau tsis tshua kim los tsim thiab dav dav, tshwj xeeb tshaj yog muab lawv siv rau hauv cov ntawv thov siab xws li steelmaking.
7. Daim ntawv thov
Tooj Electrodes: Feem ntau siv nyob rau hauv hluav taws xob tawm machining (EDM), electroplating, thiab vuam txheej txheem uas muaj hluav taws xob conductivity yog qhov tseem ceeb.
Graphite electrodes: Feem ntau siv nyob rau hauv metallurgical txheej txheem, tshwj xeeb tshaj yog nyob rau hauv hluav taws xob arc rauv rau steel ntau lawm, raws li zoo raws li nyob rau hauv ntau yam electrochemical daim ntaub ntawv xws li roj teeb thiab roj hlwb.
8. Hnav Resistance
Tooj Electrodes: Thaum lawv tuaj yeem ua tau ntev, lawv tuaj yeem hnav sai dua hauv cov ntawv thov tshwj xeeb piv rau graphite vim lawv qhov softer.
Graphite electrodes: Feem ntau muaj kev hnav zoo dua nyob rau hauv cov ntawv thov kub, uas ua rau lub neej ua haujlwm ntev dua hauv qee qhov chaw.
