Raws li peb txhua tus paub, graphite muaj cov yam ntxwv zoo uas lwm cov ntaub ntawv hlau tsis tuaj yeem hloov tau. Raws li cov khoom 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 xaiv graphite electrode cov ntaub ntawv, tab sis muaj plaub yam tseem ceeb:
Rau cov ntaub ntawv nrog tib qhov nruab nrab particle loj, lub zog thiab hardness ntawm cov ntaub ntawv uas tsis tshua muaj resistivity kuj yog me ntsis qis dua cov uas muaj siab resistivity. Uas yog hais, qhov tso tawm ceev thiab poob yuav txawv. Yog li ntawd, intrinsic resistivity ntawm graphite electrode khoom yog ib qho tseem ceeb heev rau kev siv tswv yim. Kev xaiv cov khoom siv electrode yog ncaj qha cuam tshuam rau cov nyhuv ntawm qhov paug tawm. Rau qhov loj, kev xaiv ntawm cov ntaub ntawv txiav txim siab zaum kawg ntawm kev tso tawm ceev, machining raug thiab nto roughness.
Hauv kev lag luam tshwj xeeb graphite, cov qauv ntsuas kev sib tw dav dav yog txoj kev ntsuas Shore hardness, uas nws cov qauv ntsuas txawv ntawm cov hlau. Txawm hais tias nyob rau hauv peb txoj kev nkag siab ntawm graphite, nws feem ntau suav hais tias yog cov khoom muag muag. Tab sis qhov tseeb cov ntaub ntawv xeem thiab daim ntawv thov qhia tau hais tias lub hardness ntawm graphite yog siab tshaj ntawm cov ntaub ntawv hlau. Vim yog cov txheej txheem txheej ntawm graphite, nws muaj kev ua tau zoo heev hauv cov txheej txheem txiav. Lub zog txiav tsuas yog kwv yees li 1/3 ntawm cov khoom siv tooj liab, thiab lub tshuab ua haujlwm tau yooj yim.
Txawm li cas los xij, vim nws cov hardness siab, cov cuab yeej hnav yuav yog me ntsis ntau dua li cov hlau txiav cov cuab yeej hauv kev txiav. Nyob rau tib lub sijhawm, cov khoom siv nrog lub siab hardness muaj kev tswj xyuas zoo ntawm kev tso tawm. Yog li ntawd, Shore hardness ntawm graphite electrode khoom kuj yog ib qho ntawm cov kev xaiv ntawm graphite electrode khoom.
Tom qab ntawd muaj lub zog flexural ntawm graphite electrode cov ntaub ntawv. Lub zog flexural ntawm graphite electrode cov ntaub ntawv yog qhov cuam tshuam ncaj qha ntawm lub zog ntawm cov ntaub ntawv, uas qhia cov compactness ntawm cov qauv sab hauv ntawm cov ntaub ntawv. Cov khoom siv nrog lub zog siab muaj qhov zoo tawm ntawm kev hnav tsis kam. Rau cov electrode nrog high precision, cov khoom siv nrog lub zog zoo dua yuav tsum tau xaiv kom deb li deb tau.
Thaum kawg, qhov nruab nrab particle txoj kab uas hla ntawm graphite electrode cov ntaub ntawv, qhov nruab nrab particle txoj kab uas hla ntawm graphite electrode cov ntaub ntawv ncaj qha cuam tshuam rau qhov paug ntawm cov ntaub ntawv. Qhov me me qhov nruab nrab qhov loj me, qhov sib txawv ntawm qhov paug tawm, qhov ruaj khov ntawm qhov paug tawm thiab qhov zoo ntawm qhov chaw zoo. Qhov loj dua qhov particle loj, qhov nrawm nrawm dua thiab qhov me dua qhov poob ntawm roughing. Qhov laj thawj tseem ceeb yog tias cov hluav taws xob tawm txawv txav nrog qhov kev siv tam sim no thaum lub sij hawm tso tawm. Txawm li cas los xij, qhov chaw tiav tom qab tso tawm txawv nrog qhov hloov ntawm cov khoom.
Graphite electrodes tuaj yeem yog thawj qhov kev xaiv ntawm cov ntaub ntawv hauv kev lag luam. Nws yog qhov tseeb vim tias graphite electrodes muaj qhov zoo tsis zoo uas qhov kev xaiv raug ntawm graphite electrodes thiab xaiv cov khub tsim nyog ntawm graphite electrodes yog qhov tseem ceeb.
