Uvavanyo loMgangatho weGraphite

Isishwankathelo sovavanyo

Igraphite yiallotrope yekhabhoni, icrystal transitional between atomic crystals, metal crystals and molecular crystals.Generally grey black, soft texture, greasy feeling.Ubushushu obuphuculweyo emoyeni okanye ioksijini etshisayo kwaye ivelise ikharbon diokside.Ii-oxidizing agents eziyomeleleyo ziyakuyi-oxidize zibe I-asidi ye-organic.Isetyenziswa njenge-agent ye-antiwear kunye nezinto zokuthambisa, ukwenza i-crucible, i-electrode, ibhetri eyomileyo, i-pencil lead. i-graphite emulsion, igraphite eyandisiweyo, igraphite yodongwe kunye ne-conductive graphite powder, njl.

Iimpawu ezikhethekileyo zegraphite

1. ukumelana nobushushu obuphezulu: indawo yokunyibilika yegraphite yi-3850±50℃, nasemva kokutshiswa kwe-arc yobushushu obuphezulu, ukwehla kobunzima kuncinci kakhulu, i-coefficient yokwandisa i-thermal incinci kakhulu.Amandla egraphite ayanda ngokunyuka kwamaqondo obushushu. . Kwi-2000℃, amandla egraphite aphinda kabini.
2. I-conductive, i-thermal conductivity: i-conductivity ye-graphite iphezulu ngokuphindwe kalikhulu kune-ore non-metallic ore.I-thermal conductivity yentsimbi, isinyithi, i-load kunye nezinye izinto zetsimbi. ubushushu obuphezulu, igraphite kwi-insulation;
3. i-lubricity: ukusebenza kwe-lubrication ye-graphite kuxhomekeke kubungakanani be-graphite flake, i-flake, i-friction coefficient incinci, ukusebenza kwe-lubrication kungcono;
4. ukuzinza kweekhemikhali: igraphite kwiqondo lobushushu begumbi linozinzo oluhle lweekhemikhali, ukuxhathisa kwe-asidi, ukuxhathisa kwe-alkali kunye ne-organic solvent corrosion resistance;
5. Iplastiki: ubunzima begraphite bulungile, bunokutyunyuzwa kwiphepha elincinci kakhulu;
6. ukuxhathisa ukutshatyalaliswa kwe-thermal: i-graphite kwiqondo lokushisa eliqhelekileyo xa isetyenziswe inokumelana nokutshintsha okukhulu kwiqondo lokushisa ngaphandle komonakalo, ukuguqulwa kweqondo lokushisa, umthamo wegraphite utshintshe kancinci, awuyi kuqhekeka.

Eyesibini, izikhombisi zokubona

1. uhlalutyo lokubunjwa: i-carbon esisigxina, umswakama, ukungcola, njl.;
2. Uvavanyo lwentsebenzo yomzimba: ubulukhuni, umlotha, i-viscosity, ukucoleka, ubungakanani bamasuntswana, i-volatilization, ubunzima obuthile, indawo ethile yendawo, indawo yokunyibilika, njl.
3. uvavanyo lweempawu zoomatshini: amandla okuqina, ukuqaqanjelwa, uvavanyo lokugoba, uvavanyo lokuxinana;
4. Uvavanyo lokusebenza kwemichiza: ukunganyangeki kwamanzi, ukuqina, ukuxhathisa kweasidi kunye nealkali, ukuxhathisa umhlwa, ukumelana nemozulu, ukumelana nobushushu, njl.
5. Ezinye izinto zokuvavanya: ukuhanjiswa kombane, ukuhanjiswa kwe-thermal, ukuthambisa, ukuzinza kweekhemikhali, ukuxhathisa ukothuka kwe-thermal.
