Vim li cas cov electrodes graphite muaj zog heev thiaj kim dua?

Tus nqi siab dua ntawm cov electrodes graphite muaj zog heev feem ntau yog vim lawv cov nqi khoom siv raw siab, cov txheej txheem tsim khoom nyuaj, cov txiaj ntsig zoo ntawm kev ua tau zoo, thiab kev hloov pauv ntawm kev muab khoom thiab kev thov. Kev tshuaj xyuas ntxaws ntxaws yog raws li nram no:

1. Cov Nqi Khoom Siv Raw Siab
   Cov khoom siv tseem ceeb rau cov electrodes graphite muaj zog heev yog koob coke thiab roj av coke, nrog rau koob coke yog qhov tseem ceeb. Koob coke muaj cov qauv fibrous, cov coefficient nthuav dav thermal qis, thiab yooj yim ntawm graphitization, ua rau nws yog cov khoom siv zoo tshaj plaws rau kev tsim cov electrodes graphite muaj zog lossis muaj zog heev. Txawm li cas los xij, nws cov txheej txheem tsim khoom yog qhov nyuaj, nrog rau cov teeb meem kev siv tshuab siab, thiab kev muab khoom thoob ntiaj teb tseem tsawg, ua rau tus nqi siab tas li. Tsis tas li ntawd, roj av coke, lwm yam khoom siv tseem ceeb, raug cuam tshuam los ntawm kev lag luam kev muab khoom-kev thov thiab kev hloov pauv ntawm tus nqi roj av, nrog rau tus nqi nce siab hauv xyoo tas los no. Cov nqi khoom siv raw no nce siab ncaj qha tsav cov nqi tsim khoom ntawm cov electrodes graphite muaj zog heev.

2. Cov Txheej Txheem Tsim Khoom Nyuaj
   Kev tsim cov electrodes graphite muaj zog heev muaj ntau theem, suav nrog cov khoom siv raw calcination, blending, molding, ci, impregnation, graphitization, thiab machining. Txhua kauj ruam yuav tsum tau tswj hwm cov txheej txheem kom ntseeg tau tias cov khoom zoo. Graphitization, ib theem tseem ceeb, yuav tsum tau kho ntawm qhov kub tshaj 2,000 ° C kom hloov cov qauv ntawm cov khoom siv carbon mus rau hauv cov siv lead ua graphite, txhim kho kev ua hluav taws xob thiab kev tiv taus kub siab. Cov txheej txheem no tsis yog tsuas yog siv zog ntau xwb tab sis kuj xav tau kev nqis peev ntau hauv cov khoom siv, ua rau cov nqi tsim khoom nce ntxiv.

3. Cov txiaj ntsig zoo ntawm kev ua tau zoo
   Cov electrodes graphite muaj zog heev ua rau pom cov khoom zoo heev, xws li tsis tshua muaj zog, ceev ceev, tiv taus oxidation, ua siab kub, thiab siv tsawg. Lawv qhov resistivity feem ntau poob rau hauv qhov ntau ntawm 4-6 μΩ·m, ua rau muaj kev siv hluav taws xob zoo hauv cov cub hluav taws xob arc kom tsim tau cua sov txaus rau kev yaj thiab kev ua kom huv. Piv rau cov hluav taws xob ib txwm thiab cov electrodes graphite muaj zog heev, cov hluav taws xob ultra-siab tuaj yeem tiv taus cov hluav taws xob siab dua, txo cov hlau seem yaj lub sijhawm, txo kev siv hluav taws xob, thiab txhim kho kev tsim khoom. Cov txiaj ntsig kev ua tau zoo no tsav lawv txoj kev siv dav hauv kev ua hlau, kev tsim cov phosphorus daj, kev lag luam silicon smelting, thiab lwm yam kev lag luam, ua rau muaj kev thov ua lag luam muaj zog.

4. Kev Hloov Pauv ntawm Kev Muab Khoom thiab Kev Xav Tau
   Nyob rau xyoo tas los no, kev lag luam hlau thoob ntiaj teb rov qab los thiab kev loj hlob sai ntawm cov khoom siv hluav taws xob tshiab thiab cov khoom siv siab heev tau ua rau muaj kev xav tau ntau ntxiv rau cov electrodes graphite muaj zog heev. Txawm li cas los xij, vim muaj kev txwv ntawm cov khoom siv raw thiab cov txheej txheem tsim khoom nyuaj, kev loj hlob ntawm cov khoom tsim tau qeeb qeeb, ua rau muaj kev sib cav sib ceg ntawm kev muab khoom thiab kev thov. Vim yog qhov no, tus nqi rau cov electrodes graphite muaj zog heev tau nce siab heev.
