Chifukwa cha graphite rod electrolysis

Zoyenera kupanga ma electrolytic cell: magetsi a DC. (1) DC magetsi. (2) Ma elekitirodi awiri. Ma elekitirodi awiri olumikizidwa ku mtengo wabwino wamagetsi. Pakati pawo, ma elekitirodi abwino okhudzana ndi mtengo wabwino wa magetsi amatchedwa anode, ndipo electrode yokhudzana ndi mzati woipa wa magetsi amatchedwa cathode. (3) Electrolyte solution kapena electrolyte yosungunuka.Electrolyteyankho kapena yankho 4, maelekitirodi awiri ndi electrode reaction, anode (yolumikizidwa ndi mtengo wabwino wamagetsi): anode ya okosijeni (yolumikizidwa ndi mtengo wabwino wamagetsi): cathode ya oxidation (yolumikizidwa ndi mtengo woyipa wamagetsi) magetsi): kuchepetsa reaction cathode (yolumikizidwa ndi mtengo woyipa wamagetsi): kachitidwe kocheperako (ma elekitirodi opanda pake alumikizidwa): Gulu lochepetsa 1: gulu la electrolysis 1: electrolysis CuCl2 anode cathode klorini.
     Graphitendi kristalo wa carbon. Ndizinthu zopanda zitsulo zokhala ndi imvi zasiliva, zofewa komanso zitsulo zonyezimira. Kulimba kwa Mohs ndi 1-2, mphamvu yokoka yeniyeni ndi 2.2-2.3, ndipo kachulukidwe kake kawirikawiri ndi 1.5-1.8.
Malo osungunuka a graphite amayamba kufewa akafika 3000 ℃ mu vacuum ndipo amatha kusungunuka. Ikafika 3600 ℃, graphite imayamba kusanduka nthunzi ndi kutsika. Mphamvu ya zipangizo ambiri pang`onopang`ono amachepetsa pa kutentha, pamene mphamvu graphite ndi kawiri pa firiji pamene usavutike mtima kuti 2000 ℃. Komabe, kukana kwa okosijeni kwa graphite ndikocheperako, ndipo kuchuluka kwa okosijeni kumawonjezeka pang'onopang'ono ndikuwonjezeka kwa kutentha.
Thematenthedwe madutsidwendipo madutsidwe a graphite ndi okwera kwambiri. Ma conductivity ake ndi okwera 4 kuposa chitsulo chosapanga dzimbiri, 2 nthawi zambiri kuposa chitsulo cha carbon ndi nthawi 100 kuposa chitsulo chosapanga chitsulo. Kutentha kwake kotentha sikumangopitirira zitsulo monga zitsulo, chitsulo ndi kutsogolera, komanso kumachepa ndi kuwonjezeka kwa kutentha, komwe kumasiyana ndi zitsulo zambiri. Graphite imakonda kukhala adiabatic pa kutentha kosiyana. Choncho, matenthedwe kutchinjiriza ntchito graphite ndi odalirika pa kutentha kwambiri.
Graphite ili ndi mafuta abwino komanso mapulasitiki. Mkangano wa graphite ndi wochepera 0.1. Graphite imatha kupangidwa kukhala mapepala opumira komanso owonekera. Kuuma kwa graphite yamphamvu kwambiri ndikwambiri kotero kuti kumakhala kovuta kukonza ndi zida za diamondi.
Graphite ali kukhazikika kwa mankhwala, asidi ndikukana kwa alkalindi organic zosungunulira dzimbiri kukana. Chifukwa chakuti graphite ili ndi zinthu zabwino kwambiri zomwe zili pamwambazi, ikugwiritsidwa ntchito kwambiri m'makampani amakono.
