Isizathu se-graphite rod electrolysis

Izimo zokwenza iseli ye-electrolytic: Ukunikezwa kwamandla ka-DC. (1) Ukunikezwa kukagesi kwe-DC. (2) Ama-electrode amabili. Ama-electrode amabili axhunywe esigxotsheni esihle sokuphakelwa kwamandla. Phakathi kwazo, i-electrode enhle exhunywe nesigxobo esihle sokunikezwa kwamandla ibizwa ngokuthi i-anode, futhi i-electrode exhunywe nesigxobo esingalungile sokunikezwa kwamandla kuthiwa yi-cathode. (3) Isixazululo se-Electrolyte noma i-electrolyte encibilikisiwe.I-Electrolyteisisombululo noma isixazululo 4, ama-electrode amabili kanye ne-electrode reaction, i-anode (exhunywe esigxotsheni esihle samandla kagesi): i-anode ye-oxidation reaction (exhunywe esigxotsheni esihle sokuphakelwa kwamandla): i-oxidation reaction cathode (exhunywe esigxotsheni esinegethivu ukunikezwa kwamandla): i-cathode yokusabela encishisiwe (ixhunywe esigxotsheni esinegethivu samandla kagesi): ukusabela kokunciphisa (i-electrode engalungile ixhunyiwe): iqembu lokunciphisa 1: iqembu le-electrolysis 1: i-electrolysis CuCl2 anode cathode chlorine.
     I-graphiteiyikristalu yekhabhoni. Kuyimpahla engeyona eyensimbi enombala ompunga oyisiliva, icwebezela elithambile nelensimbi. Ubulukhuni be-Mohs bungu-1-2, amandla adonsela phansi athile angu-2.2-2.3, futhi ukuminyana kwawo ngobuningi ngokuvamile kungu-1.5-1.8.
Iphuzu elincibilikayo le-graphite liqala ukuthamba lapho lifinyelela ku-3000 ℃ ku-vacuum futhi livame ukuncibilika. Uma ifinyelela ku-3600 ℃, i-graphite iqala ukuhwamuka futhi i-sublimate. Amandla ezinto ezivamile ayancipha kancane kancane ekushiseni okuphezulu, kuyilapho amandla egraphite ephindwe kabili kunaleyo ekamelweni lokushisa lapho ishiselwa ku-2000 ℃. Kodwa-ke, ukumelana ne-oxidation ye-graphite kubi, futhi izinga le-oxidation liyakhula kancane kancane ngokunyuka kwezinga lokushisa.
Iconductivity ezishisayofuthi conductivity of graphite ziphakeme impela. I-conductivity yayo iphakeme izikhathi ezi-4 kuneyensimbi engagqwali, izikhathi ezi-2 ziphakeme kune-carbon steel futhi izikhathi eziyi-100 ziphakeme kunezingezona ezensimbi ezijwayelekile. I-conductivity yayo eshisayo ayidluli nje kuphela izinto zensimbi ezifana nensimbi, insimbi nomthofu, kodwa futhi iyancipha ngokunyuka kwezinga lokushisa, elihlukile ezintweni zensimbi ezijwayelekile. I-graphite ijwayele ukuba ne-adiabatic emazingeni okushisa ahlukene. Ngakho-ke, ukusebenza kokushisa okushisayo kwe-graphite kunokwethenjelwa kakhulu ekushiseni okuphezulu.
I-graphite inokuthambisa okuhle kanye nepulasitiki. I-coefficient ye-friction ye-graphite ingaphansi kuka-0.1. I-graphite ingathuthukiswa ibe amashidi aphefumulayo nasobala. Ukuqina kwe-graphite ephezulu kakhulu kangangokuthi kunzima ukucubungula ngamathuluzi wedayimane.
I-graphite inokuqina kwamakhemikhali, i-asidi kanyeukumelana ne-alkalikanye ne-organic solvent corrosion resistance. Ngenxa yokuthi i-graphite inezindawo ezinhle kakhulu ezingenhla, isetshenziswa kabanzi embonini yesimanje.
