I-graphite i-allotrope of carbon, icrystal transitional between atomic crystals, metal crystals and molecular crystals.Ngokuvamile okumpunga okumnyama, ukuthungwa okuthambile, ukuzwa okunamafutha.Ukushisa okuthuthukisiwe emoyeni noma komoya-mpilo okuvutha futhi kukhiqize ikhabhoni dioxide.Izinto ezinamandla eziyi-oxidizing zizowuxilisa Isetshenziswa njenge-agent ye-antiwear kanye nezinto zokugcoba, ukwenza i-crucible, i-electrode, ibhethri elomile, i-pencil lead. Ububanzi bokutholwa kwe-graphite: i-graphite yemvelo, i-crystalline graphite eminyene, i-flake graphite, i-cryptocrystalline graphite, i-graphite powder, i-graphite paper, i-graphite enwetshiwe, i-graphite emulsion, i-graphite eyandisiwe, i-graphite yobumba kanye ne-conductive graphite powder, njll.
1. ukumelana nokushisa okuphezulu: indawo encibilikayo yegraphite ingu-3850 ± 50 ℃, ngisho nangemva kokushiswa kwe-arc yokushisa kwe-ultra-high, ukuncipha kwesisindo kuncane kakhulu, i-coefficient yokwandisa okushisayo incane kakhulu.Amandla egraphite ayanda ngokunyuka kwezinga lokushisa. . Ku-2000 ℃, amandla e-graphite aphindeka kabili.
2. conductive, conductivity thermal: conductivity of graphite ephakeme izikhathi eziyikhulu kune-non-metallic ore jikelele.I-conductivity eshisayo yensimbi, insimbi, umthofu nezinye izinto zensimbi.I-conductivity ye-thermal iyancipha ngokunyuka kwezinga lokushisa, ngisho nasezingeni eliphezulu kakhulu. izinga lokushisa eliphezulu, 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
