Chifukwa cha electrolysis ya ndodo ya graphite

Zofunikira popanga selo yamagetsi: Mphamvu yamagetsi ya DC. (1) Mphamvu yamagetsi ya DC. (2) Ma electrode awiri. Ma electrode awiri olumikizidwa ku positive pole yamagetsi. Pakati pawo, positive electrode yolumikizidwa ndi positive pole yamagetsi imatchedwa anode, ndipo electrode yolumikizidwa ndi negative pole yamagetsi imatchedwa cathode. (3) Electrolyte solution kapena electrolyte yosungunuka.Electrolyteyankho kapena yankho 4, ma electrode awiri ndi reaction ya electrode, anode (yolumikizidwa ku positive pole yamagetsi): oxidation reaction anode (yolumikizidwa ku positive pole yamagetsi): oxidation reaction cathode (yolumikizidwa ku negative pole yamagetsi): reduction reaction cathode (yolumikizidwa ku negative pole yamagetsi): reduction reaction cathode (yolumikizidwa ku negative pole yamagetsi): reduction reaction (negative electrode connected): reduction group 1: electrolysis group 1: electrolysis ya CuCl2 anode cathode chlorine.
     Graphitendi galasi la kaboni. Ndi chinthu chosakhala chachitsulo chokhala ndi mtundu wa imvi wasiliva, chofewa komanso chonyezimira chachitsulo. Kulimba kwa Mohs ndi 1-2, mphamvu yokoka yeniyeni ndi 2.2-2.3, ndipo kuchuluka kwake kwakukulu nthawi zambiri kumakhala 1.5-1.8.
Malo osungunuka a graphite amayamba kufewa akafika pa 3000 ℃ mu vacuum ndipo nthawi zambiri amasungunuka. Akafika pa 3600 ℃, graphite imayamba kusungunuka ndi kusungunuka. Mphamvu ya zinthu zonse imachepa pang'onopang'ono kutentha kwambiri, pomwe mphamvu ya graphite imawirikiza kawiri kutentha kwa chipinda ikatenthedwa kufika pa 2000 ℃. Komabe, kukana kwa okosijeni kwa graphite ndi kochepa, ndipo kuchuluka kwa okosijeni kumawonjezeka pang'onopang'ono kutentha kukakwera.
Thekutentha kwa mpweyandipo mphamvu ya graphite ndi yapamwamba kwambiri. Mphamvu yake yoyendetsera zinthu ndi yokwera kasanu kuposa ya chitsulo chosapanga dzimbiri, kawiri kuposa ya chitsulo cha kaboni komanso nthawi 100 kuposa ya chitsulo chosakhala chachitsulo. Mphamvu yake yoyendetsera zinthu kutentha sikuti imaposa ya chitsulo monga chitsulo, chitsulo ndi lead, komanso imachepa ndi kutentha komwe kumawonjezeka, komwe kumasiyana ndi zinthu zachitsulo wamba. Graphite nthawi zambiri imakhala ya adiabatic pa kutentha kosiyanasiyana. Chifukwa chake, mphamvu ya graphite yotetezera kutentha ndi yodalirika kwambiri pa kutentha kwakukulu.
Graphite ili ndi mafuta abwino komanso pulasitiki wabwino. Graphite imachepa ndi 0.1. Graphite imatha kupangidwa kukhala mapepala opumira komanso owonekera bwino. Kulimba kwa graphite yamphamvu kwambiri ndi kwakukulu kwambiri kotero kuti zimakhala zovuta kuikonza ndi zida za diamondi.
Graphite ili ndi kukhazikika kwa mankhwala, asidi ndikukana kwa alkalikomanso kukana dzimbiri kwa zinthu zosungunulira zachilengedwe. Popeza graphite ili ndi makhalidwe abwino kwambiri omwe ali pamwambapa, imagwiritsidwa ntchito kwambiri m'mafakitale amakono.
