Peb txhua tus paub tias graphite muaj lwm cov ntaub ntawv hlau tsis tuaj yeem hloov cov yam ntxwv zoo, raws li cov khoom nyiam,graphite electrodecov khoom siv hauv kev xaiv cov ntaub ntawv tiag tiag feem ntau muaj ntau yam tsis meej pem, kev xaiv cov khoom siv graphite electrode kuj muaj ntau lub hauv paus, tab sis plaub tus qauv 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 yuav tsawg dua cov uas muaj siab resistivity.Ntawd yog, qhov ceev ntawm kev tso tawm, poob yuav txawv.Yog li ntawd, natural resistivity ntawmgraphite electrodecov ntaub ntawv, nyob rau hauv lub tswv yim daim ntawv thov ntawm yuav tsum tau xaiv cov ntaub ntawv tseem ceeb heev.Qhov kev xaiv ntawm cov khoom siv electrode yog ncaj qha ntsig txog cov nyhuv tawm.Rau qhov loj, txawm tias cov khoom raug xaiv kom raug txiav txim siab qhov kev tso tawm ceev, kev ua haujlwm raug thiab qhov roughness.

Hauv kev lag luam tshwj xeeb graphite, cov qauv kev ntsuas qhov hnyav dav dav yog txoj kev ntsuas Shore hardness, cov qauv ntsuas txawv ntawm cov hlau.Txawm hais tias peb nyob rau hauv lub subconscious nkag siab ntawm graphite, nws yog feem ntau suav hais tias yog ib tug kuj mos cov ntaub ntawv.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 hais tias ntawm cov txheej txheem txheej ntawm graphite, yog li ntawd nws muaj superior txiav kev ua tau zoo nyob rau hauv cov txheej txheem txiav, txiav quab yuam tsuas yog hais txog 1/3 ntawm cov khoom siv tooj liab, machined nto yog ib qho yooj yim los daws.

Tab sis vim nws cov hardness siab dua, hauv kev txiav, qhov poob ntawm lub cuab yeej yuav yog me ntsis ntau dua li cov cuab yeej txiav ntawm cov hlau.Nyob rau tib lub sijhawm, cov khoom siv nrog cov hardness siab muaj kev tswj xyuas zoo dua ntawm kev tso tawm.Yog li ntawd, lub ntug hardness ntawmgraphite electrodecov khoom kuj yog ib qho ntawm cov kev xaiv ntawm graphite electrode khoom.

Tom qab ntawd muaj qhov khoov lub zog ntawm cov khoom siv graphite electrode.Lub zog dabtsi yog khoov ntawm cov khoom siv graphite electrode yog ib qho kev cuam tshuam ncaj qha ntawm lub zog ntawm cov khoom, uas qhia qhov nruj ntawm cov qauv sab hauv ntawm cov khoom.Cov khoom siv zog siab, nws qhov kev tawm tsis zoo kuj yog qhov zoo, rau qhov kev xav tau ntawm cov electrode, sim xaiv cov khoom siv zog zoo dua.

Thaum kawg, qhov nruab nrab particle txoj kab uas hla ntawm cov khoom siv graphite electrode ncaj qha cuam tshuam rau qhov paug ntawm cov khoom.Qhov me me qhov nruab nrab ntawm cov khoom siv, qhov sib txawv ntawm cov khoom siv, qhov ruaj khov ntawm qhov paug tawm, qhov zoo ntawm qhov chaw zoo.Qhov loj dua qhov particle, qhov nrawm nrawm dua, qhov me dua qhov poob ntawm qhov ntxhib machining.Qhov laj thawj tseem ceeb yog qhov kev tawm dag zog sib txawv vim qhov sib txawv tam sim no siv.Txawm li cas los xij, qhov chaw ua tiav tom qab tso tawm kuj tseem hloov nrog kev hloov ntawm cov khoom.

Graphite electrodetuaj yeem dhau los ua cov khoom siv hauv kev lag luam, nws yog vim cov graphite electrode muaj qhov tsis zoo, yog li cov khoom siv raug xaiv ntawm graphite electrode, haum rau graphite electrode yog qhov tseem ceeb.
