Raws li peb txhua tus paub, graphite muaj cov yam ntxwv zoo uas lwm cov khoom siv hlau tsis tuaj yeem hloov tau. Raws li cov khoom siv nyiam, cov ntaub ntawv graphite electrode feem ntau muaj ntau yam tsis meej pem hauv kev xaiv cov ntaub ntawv tiag tiag. Muaj ntau lub hauv paus rau kev xaiv cov ntaub ntawv graphite electrode, tab sis muaj plaub qhov tseem ceeb:
Rau cov ntaub ntawv uas muaj qhov nruab nrab ntawm cov khoom me me, lub zog thiab qhov nyuaj ntawm cov ntaub ntawv uas muaj qhov tsis kam kuj qis dua li cov uas muaj qhov tsis kam siab. Uas yog hais tias, qhov ceev ntawm kev tawm thiab kev poob yuav txawv. Yog li ntawd, qhov tsis kam ntawm cov khoom siv graphite electrode yog qhov tseem ceeb heev rau kev siv ua haujlwm. Kev xaiv cov ntaub ntawv electrode yog ncaj qha cuam tshuam nrog cov nyhuv ntawm kev tawm. Feem ntau, kev xaiv cov ntaub ntawv txiav txim siab qhov kawg ntawm kev tawm ceev, kev ua haujlwm raug thiab qhov roughness ntawm qhov chaw.
Hauv kev lag luam graphite tshwj xeeb, tus qauv ntsuas qhov nyuaj dav dav yog Shore hardness testing method, uas nws txoj cai ntsuas txawv ntawm cov hlau. Txawm hais tias hauv peb qhov kev nkag siab txog graphite, feem ntau nws suav tias yog cov khoom mos. Tab sis cov ntaub ntawv xeem tiag tiag thiab daim ntawv thov qhia tias qhov nyuaj ntawm graphite siab dua li cov khoom siv hlau. Vim yog cov qauv txheej txheem ntawm graphite, nws muaj kev ua tau zoo heev hauv cov txheej txheem txiav. Lub zog txiav tsuas yog li 1/3 ntawm cov khoom siv tooj liab, thiab qhov chaw ua haujlwm yooj yim rau kev tuav.
Txawm li cas los xij, vim nws qhov nyuaj siab, qhov hnav ntawm cov cuab yeej yuav ntau dua li cov cuab yeej txiav hlau hauv kev txiav. Tib lub sijhawm, cov khoom siv uas muaj qhov nyuaj siab muaj kev tswj hwm zoo ntawm kev poob tawm. Yog li ntawd, Shore hardness ntawm cov khoom siv graphite electrode kuj yog ib qho ntawm cov qauv xaiv ntawm cov khoom siv graphite electrode.
Tom qab ntawd muaj lub zog khoov ntawm cov khoom siv graphite electrode. Lub zog khoov ntawm cov khoom siv graphite electrode yog qhov kev cuam tshuam ncaj qha ntawm lub zog ntawm cov khoom siv, qhia txog qhov compactness ntawm cov qauv sab hauv ntawm cov khoom siv. Cov khoom siv uas muaj zog siab muaj kev tiv thaiv kev hnav tawm zoo. Rau cov electrode uas muaj qhov tseeb siab, cov khoom siv uas muaj zog zoo dua yuav tsum tau xaiv kom deb li deb tau.
Thaum kawg, qhov nruab nrab ntawm cov khoom me me ntawm cov khoom siv graphite electrode, qhov nruab nrab ntawm cov khoom me me ntawm cov khoom siv graphite electrode cuam tshuam ncaj qha rau qhov xwm txheej ntawm cov khoom tawm. Qhov me me ntawm qhov nruab nrab ntawm cov khoom me me, qhov sib npaug ntawm qhov tawm, qhov ruaj khov ntawm qhov tawm thiab qhov zoo dua ntawm qhov chaw. Qhov loj me ntawm cov khoom me me, qhov ceev ntawm qhov tawm thiab qhov poob ntawm roughing me me. Qhov laj thawj tseem ceeb yog tias lub zog tawm sib txawv nrog lub zog tam sim no thaum lub sijhawm tawm. Txawm li cas los xij, qhov tiav ntawm qhov chaw tom qab tawm sib txawv nrog qhov kev hloov pauv ntawm cov khoom me me.
Cov hluav taws xob graphite yog thawj qhov kev xaiv ntawm cov ntaub ntawv hauv kev lag luam. Vim tias cov hluav taws xob graphite muaj qhov zoo tshaj plaws, cov qauv xaiv cov hluav taws xob graphite thiab kev xaiv cov khub hluav taws xob graphite tsim nyog yog qhov tseem ceeb.
