Chikonzero che graphite tsvimbo electrolysis

Mamiriro ekugadzira electrolytic cell: DC magetsi ekupa. (1) DC simba rekupa. (2) Ma electrode maviri. Ma electrode maviri akabatanidzwa kune yakanaka pole yemagetsi ekupa. Pakati pavo, iyo electrode yakanaka yakabatana neiyo danda remagetsi remagetsi inonzi anode, uye iyo electrode yakabatana neiyo yakaipa pole yemagetsi inonzi cathode. (3) Electrolyte solution kana electrolyte yakanyungudutswa.Electrolytemhinduro kana mhinduro 4, maelectrode maviri uye electrode reaction, anode (yakabatana kune yakanaka danda remagetsi emagetsi): oxidation reaction anode (yakabatana kune yakanaka danda remagetsi emagetsi): oxidation reaction cathode (yakabatana neiyo yakaipa danda magetsi): kudzikisa reaction cathode (yakabatana nedanda rakashata remagetsi emagetsi): maitiro ekudzikisa (negative electrode yakabatana): boka rekudzikisa 1: boka re electrolysis 1: electrolysis ye CuCl2 anode cathode chlorine.
     Graphiteikristaro yekabhoni. Icho chinhu chisiri chesimbi chine sirivheri grey ruvara, yakapfava uye simbi inopenya. Kuoma kweMohs ndeye 1-2, giravhiti chaiyo ndeye 2.2-2.3, uye huwandu hwayo huzhinji hunowanzo 1.5-1.8.
Nzvimbo yekunyungudika yegraphite inotanga kupfava kana yasvika 3000 ℃ muvacuum uye inoita kunyungudika. Kana yasvika 3600 ℃, graphite inotanga kubuda uye sublimate. Simba rezvinhu zvakajairika zvishoma nezvishoma rinodzikira pakupisa kwepamusoro, nepo simba regraphite rakapetwa kaviri pane tembiricha yekamuri kana ichipisa kusvika 2000 ℃. Nekudaro, iyo oxidation kuramba yegraphite haina kunaka, uye mwero weoxidation unowedzera zvishoma nezvishoma nekuwedzera kwekushisa.
Thethermal conductivityuye conductivity yegraphite yakakwira zvakanyanya. Conductivity yaro yakakwira 4 nguva kupfuura yesimbi isina tsvina, 2 nguva yakakwirira kupfuura iyo carbon steel uye 100 nguva yakakwirira kupfuura iyo yakawanda isiri-simbi. Thermal conductivity yaro haingopfuuri chete yezvigadzirwa zvesimbi zvakadai sesimbi, iron uye lead, asi zvakare inoderera nekuwedzera kwekushisa, iyo yakasiyana neyakajairwa simbi zvinhu. Graphite inotoita kunge adiabatic pane tembiricha dzakasiyana. Naizvozvo, iyo thermal insulation performance yegraphite inovimbika zvakanyanya pakupisa kwakanyanya.
Graphite ine lubricity yakanaka uye plastiki. Iko friction coefficient yegraphite isingasviki 0.1. Graphite inogona kuvandudzwa kuita mapepa anofema uye akajeka. Kuoma kwepamusoro-simba graphite yakakura zvokuti zvakaoma kugadzirisa nemidziyo yedhaimondi.
Graphite ine kugadzikana kwemakemikari, asidhi uyealkali resistanceuye organic solvent corrosion resistance. Nekuti graphite ine zvinhu zvakanakisa zviri pamusoro apa, iri kuwedzera kushandiswa zvakanyanya muindasitiri yemazuva ano.
