Dab tsi yog cov txheej txheem nthuav dav ntawm graphite electrode?
Cov roj hauv lub roj teeb sab hauv yog qhov ua rau cov roj teeb o. Txawm hais tias lub roj teeb nyob rau hauv ib txwm ua haujlwm, qhov kub thiab txias, thiab khaws cia ntawm qhov kub thiab txias, qhov no yuav ua rau cov pa roj sib txawv. Graphite electrodes yog tsim los ntawm roj av coke thiab rab koob coke li raw cov ntaub ntawv, asphalt mastic raws li ib tug fusion agent, thiab yog tsim los ntawm calcination, seasoning, kneading, nias, ci, graphitization, thiab machining. Lawv yog cov khoom siv hluav taws xob uas ua kom sov thiab yaj cov khoom pov tseg hauv nruab nrab ntawm lub tshuab hluav taws xob los ntawm kev tso hluav taws xob hluav taws xob hauv daim ntawv ntawm arc. Raws li lawv cov qauv zoo, lawv tuaj yeem muab faib ua lub zog dav dav, siab zog thiab ultra-siab zog. Graphite electrodes feem ntau suav nrog cov hluav taws xob dav dav graphite electrodes, tiv thaiv oxidation coated graphite electrodes, siab zog graphite electrodes thiab ultra-siab zog graphite electrodes.
Graphite rods feem ntau yog siv nyob rau hauv hluav taws xob cua sov caij ntawm high-temperature nqus tsev vacuum furnaces. Qhov siab tshaj plaws daim ntawv thov kub ncav cuag 3000 degree. Lawv yooj yim rau oxidize ntawm qhov kub thiab txias. Tsuas yog lub tshuab nqus tsev twj, lawv tsuas yog siv tau rau hauv nruab nrab lossis oxidizing cua. Nws cov linear expansion coefficient yog me me, thermal conductivity yog loj, thiab resistivity index yog (8 ~ 13) × 10-6Ω·m. Nws cov txheej txheem ua tau zoo dua li ntawm SiC thiab MoSi2 rods. Nws yog tshav kub-resistant, tsis tshua muaj txias thiab polar tshav kub-resistant, thiab nws cov nqi kuj pheej yig. Graphite block yog ib hom hluavtaws graphite, thiab hluavtaws graphite yog tsim los ntawm cov txheej txheem xws li cua sov ntawm cov khoom siv coke. Feem ntau, yog tias nws yog purified mus rau lub siab purity, los yog ua rau carbon fiber, tus nqi ntxiv yuav siab. Nws tau raug pov thawj tias cov yam ntxwv uas ua rau lub roj teeb o yog tshwm sim los ntawm kev tawg ntawm lithium roj teeb electrolyte. Muaj ob yam xwm txheej rau kev tawg ntawm lithium roj teeb electrolyte. Cov electrolyte yog ib qho residue, hlau residue xws li dej thiab electrolyte hnyav roj. Lwm qhov yog tias photocatalytic dialog box ntawm cov electrolyte tsawg dhau lawm, ua rau cov kev sib cais thaum lub sijhawm them cov roj teeb. Cov kuab tshuaj tau tom qab electrolyte EC thiab DEC, xws li cov hluav taws xob, yuav tsim cov pa oxygen radicals, uas yog cov txiaj ntsig ncaj qha los ntawm cov tshuaj tiv thaiv radical los tsim cov tshuaj nitrogen tsawg, lipids, ethers, thiab CO2.
