I-graphite i-allotrope of carbon, icrystal transitional between atomic crystals, metal crystals and molecular crystals.Ngokuvamile grey black, soft texture, greasy feeling.Ukushisa okuthuthukisiwe emoyeni noma umoya-mpilo oshisa futhi ukhiqize ikhabhoni dioxide.Izinto ezisebenza nge-oxidizing ezinamandla zizoyi-oxidize ibe ama-organic acids.Isetshenziswa njenge-agent e-lubricacible, eyomile yebhethri, yenza i-electrowear, i-anticrucible, i-electronic material eyomile. umsizi wepensela.Ububanzi bokutholwa kwe-graphite: igraphite yemvelo, i-crystalline graphite eminyene, i-flake graphite, i-cryptocrystalline graphite, i-graphite powder, iphepha le-graphite, i-graphite enwetshiwe, i-graphite emulsion, i-graphite enwetshiwe, i-clay graphite ne-conductive graphite powder, njll.
1. ukumelana nokushisa okuphezulu: indawo yokuncibilika ye-graphite ingu-3850 ± 50 ℃, ngisho nangemva kokushiswa kwe-arc yokushisa kwe-ultra-high, ukulahlekelwa kwesisindo kuncane kakhulu, i-coefficient yokwandisa okushisayo incane kakhulu.Amandla e-graphite ayanda ngokunyuka kwezinga lokushisa. Ku-2000 ℃, amandla e-graphite aphindeka kabili.
2. I-conductive, i-thermal conductivity: i-conductivity ye-graphite iphindwe izikhathi eziyikhulu kune-ore jikelele engeyona eyensimbi.I-thermal conductivity yensimbi, insimbi, i-lead nezinye izinto zensimbi.I-Conductivity yokushisa iyancipha ngokunyuka kwezinga lokushisa, ngisho namazinga okushisa aphezulu kakhulu, i-graphite ibe yi-insulation;
3. Lubricity: ukusebenza kokugcoba kwe-graphite kuncike kusayizi we-graphite flake, i-flake, i-friction coefficient incane, ukusebenza kokugcoba kungcono;
4. Ukuqina kwamakhemikhali: I-graphite ekamelweni lokushisa inokuqina okuhle kwamakhemikhali, ukumelana ne-asidi, ukumelana ne-alkali kanye nokumelana nokugqwala kwe-organic solvent;
5. Ipulasitiki: ukuqina kwe-graphite kuhle, kungachotshozwa ibe ishidi elincane kakhulu;
6. Ukumelana nokushaqeka okushisayo: i-graphite ekamelweni lokushisa lapho isetshenziswa ingakwazi ukumelana nezinguquko ezinkulu ekushiseni ngaphandle kokulimala, ukuguqulwa kwezinga lokushisa, umthamo we-graphite ushintsha kancane, ngeke uqhekeke.
1. ukuhlaziya ukwakheka: ikhabhoni engaguquki, umswakama, ukungcola, njll.;
2. Ukuhlolwa kokusebenza komzimba: ubulukhuni, umlotha, i-viscosity, ubuhle, usayizi wezinhlayiyana, ukuguquguquka, amandla adonsela phansi athile, indawo ethile, indawo encibilikayo, njll.
3. ukuhlolwa kwezakhiwo zemishini: amandla aqinile, ukuqina, ukuhlolwa kokugoba, ukuhlolwa okuqinile;
4. ukuhlolwa kokusebenza kwamakhemikhali: ukumelana namanzi, ukuqina, ukumelana ne-asidi ne-alkali, ukumelana nokugqwala, ukumelana nesimo sezulu, ukumelana nokushisa, njll.
5. Ezinye izinto zokuhlola: i-conductivity kagesi, i-thermal conductivity, i-lubrication, ukuqina kwamakhemikhali, ukumelana nokushaqeka okushisayo
