Yog vim li cas rau graphite pas nrig electrolysis

Cov xwm txheej rau kev tsim electrolytic cell: DC fais fab mov. (1) DC fais fab mov. (2) Ob lub electrodes. Ob lub electrodes txuas nrog tus ncej zoo ntawm lub hwj huam mov. Ntawm lawv, qhov zoo electrode txuas nrog tus ncej zoo ntawm lub zog hluav taws xob yog hu ua anode, thiab cov electrode txuas nrog lub cev tsis zoo ntawm lub zog hluav taws xob hu ua cathode. (3) Electrolyte tov los yog molten electrolyte.Electrolytekev daws teeb meem los yog kev daws teeb meem 4, ob lub electrodes thiab electrode cov tshuaj tiv thaiv, anode (txuas mus rau lub zoo ncej ntawm lub hwj chim mov): oxidation cov tshuaj tiv thaiv anode (txuas mus rau lub zoo ncej ntawm lub hwj chim mov): oxidation cov tshuaj tiv thaiv cathode (txuas mus rau lub tsis zoo ncej ntawm lub fais fab mov): txo cov tshuaj tiv thaiv cathode (txuas mus rau qhov tsis zoo ncej ntawm lub hwj huam mov): txo cov tshuaj tiv thaiv (tsis zoo electrode txuas): txo pawg 1: electrolysis pawg 1: electrolysis ntawm CuCl2 anode cathode tshuaj chlorine.
     Graphiteyog ib tug crystal ntawm carbon. Nws yog cov khoom siv tsis yog xim hlau nrog nyiaj grey xim, mos thiab xim hlau luster. Mohs hardness yog 1-2, lub ntiajteb txawj nqus tshwj xeeb yog 2.2-2.3, thiab nws qhov ntom ntom feem ntau yog 1.5-1.8.
Lub melting point ntawm graphite pib soften thaum nws mus txog 3000 ℃ hauv lub tshuab nqus tsev thiab zoo li yaj. Thaum nws ncav cuag 3600 ℃, graphite pib evaporate thiab sublimate. Lub zog ntawm cov khoom siv maj mam txo qis ntawm qhov kub thiab txias, thaum lub zog ntawm graphite yog ob zaug uas nyob rau hauv chav tsev kub thaum nws rhuab mus rau 2000 ℃. Txawm li cas los xij, oxidation tsis kam ntawm graphite tsis zoo, thiab oxidation tus nqi maj mam nce nrog qhov kub thiab txias.
Covthermal conductivitythiab conductivity ntawm graphite yog heev. Nws cov conductivity yog 4 npaug siab dua ntawm cov hlau tsis muaj steel, 2 npaug siab dua cov hlau carbon thiab 100 npaug siab dua li cov hlau tsis yog hlau. Nws cov thermal conductivity tsis tsuas yog tshaj li cov khoom siv hlau xws li hlau, hlau thiab txhuas, tab sis kuj txo qis nrog qhov kub thiab txias, uas txawv ntawm cov khoom siv hlau dav dav. Graphite txawm zoo li adiabatic ntawm qhov kub sib txawv. Yog li ntawd, thermal rwb thaiv tsev kev ua tau zoo ntawm graphite yog heev txhim khu kev qha nyob rau hauv high kub.
Graphite muaj lubricity zoo thiab plasticity. Kev sib txhuam coefficient ntawm graphite yog tsawg dua 0.1. Graphite tuaj yeem tsim rau hauv cov ntawv ua pa thiab pob tshab. Lub hardness ntawm high-strength graphite yog zoo heev uas nws yog ib qho nyuaj rau txheej txheem nrog pob zeb diamond cov cuab yeej.
Graphite muaj tshuaj stability, acid thiabalkali tsis kamthiab organic hnyav corrosion kuj. Vim tias graphite muaj cov khoom zoo tshaj plaws, nws tau siv dav hauv kev lag luam niaj hnub no.
