I-graphite ingawuthatha njani indawo yobhedu njenge-electrode?Amandla aphezulu oomatshini iGraphite Electrode China.
Kwiminyaka yoo-1960, ubhedu lwalusetyenziswa kakhulu njengezinto ze-electrode, izinga lokusetyenziswa limalunga ne-90% kwaye i-graphite yayimalunga ne-10%. Kwinkulungwane yama-21, abasebenzisi abaninzi baqala ukukhetha i-graphite njengezinto ze-electrode. EYurophu, ngaphezulu kwe-90% yezinto ze-electrode yi-graphite. Ubhedu, olwalukade luyinto elawulayo ye-electrode, phantse luphulukene nomphetho walo ngaphezu kwe-graphite. Yintoni eyabangela olu tshintsho lukhulu? Kakade ke, kukho iingenelo ezininzi ze-graphite electrode.
(1) isantya sokucubungula esikhawulezayo: ngokubanzi, isantya sokucubungula ngoomatshiniI-Graphite Electrode iyathengiswainokuba ngokukhawuleza ngokuphindwe kabini ukuya kahlanu kuneyobhedu; Nangona kunjalo, i-edm ikhawuleza ngokuphindwe kabini ukuya kathathu kunethusi, kwaye izinto azinangxaki yokuguquka. Indawo yokuthambisa yobhedu imalunga ne-1000 degrees, kwaye kulula ukuyitshintsha bubushushu. Ubushushu be-Graphite sublimation yi-3650 degrees; I-coefficient yokwandiswa kobushushu yi-1/30 kuphela yobhedu.
(2) ubunzima obulula: uxinano lwegrafiti yi-1/5 kuphela yolo lobhedu, olunokunciphisa ngempumelelo umthwalo wesixhobo somatshini (EDM) xa ii-electrode ezinkulu zicutshungulwa ngokukhupha; Ifanelekile ngakumbi ukusetyenziswa kwesikhunta esikhulu.
(3) ukusetyenziswa kokukhupha kuncinci; Ekubeni ioyile yentlantsi ikwanazo neeathom ze-C, ngexesha lokucubungula ukukhupha, ubushushu obuphezulu bubangela ukuba iiathom ze-C kwioyile yentlantsi zibole, nto leyo eyenza ifilimu ekhuselayo kumphezulu we-graphite electrode, ihlawulela ukulahleka kwe-graphite electrode.
(4) akukho zibher; Emva kokuba i-electrode yobhedu isetyenzisiwe, kufuneka inqunyulwe ngesandla ukuze kususwe izibher, ngelixa i-graphite isetyenzwa yi-Umzi-mveliso weGraphite Electrodengaphandle kwee-burrs, nto leyo egcina iindleko ezininzi kwaye yenza kube lula ukwenza imveliso ngokuzenzekelayo
(5) igrafiti kulula ukuyigaya nokuyipolisha; Ekubeni igrafiti inesinye kwisihlanu kuphela sokumelana nokusika kobhedu, kulula ukuyigaya nokuyipolisha ngesandla.
(6) ixabiso eliphantsi lezinto ezibonakalayo kunye nexabiso elizinzileyo; Ngenxa yokunyuka kwexabiso lekopolo kwiminyaka yakutshanje, ixabiso le-isotropic graphite liphantsi kunelekopolo. Phantsi komthamo ofanayo, ixabiso leemveliso ze-graphite ngokubanzi ze-toyo carbon liphantsi ngama-30% ~ 60% kunelekopolo, kwaye ixabiso lizinzile ngakumbi, ukuguquguquka kwexabiso lexesha elifutshane kuncinci kakhulu.
Ngenxa yolu ncedo lungenakuthelekiswa nanto, i-graphite iye yathatha indawo yobhedu kancinci kancinci njengesixhobo esikhethwayo se-electrode ye-EDM.
