I-graphite iyi-allotrope yekhabhoni, ikristalu yesikhashana phakathi kwamakristalu e-athomu, amakristalu wensimbi namakristalu wamangqamuzana.Ngokujwayelekile umbala omnyama ompunga, ukuthamba okuthambile, umuzwa onamafutha.Ukushisa okuthuthukisiwe emoyeni noma ku-oksijini okushisa futhi kukhiqize i-carbon dioxide. organic acids.Usetshenziswa njenge-antiwear agent kanye nezinto zokuthambisa, okwenza i-crucible, i-electrode, ibhethri elomile, ipensela yomthofu.Ububanzi bokutholwa kwe-graphite: i-graphite yemvelo, i-dense crystalline graphite, i-flake graphite, i-cryptocrystalline graphite, i-graphite powder, iphepha le-graphite, i-graphite enwetshiwe, i-graphite emulsion, i-graphite enwetshiwe, i-graphite yobumba kanye ne-conductive graphite powder, njll.
1. ukumelana nokushisa okuphezulu: indawo yokuncibilika ye-graphite ingu-3850 ± 50 ℃, noma ngemuva kokushisa okushisa kakhulu kwe-arc, ukwehla kwesisindo kuncane kakhulu, i-coefficient yokwanda okushisayo incane kakhulu. Amandla we-graphite ayanda ngokwanda kwezinga lokushisa . Ku-2000 ℃, amandla we-graphite aphindeka kabili.
2. conductive, conductivity ezishisayo: i-conductivity ye-graphite iphindwe izikhathi eziyikhulu kune-ore non-metallic jikelele.Ukuqhutshwa okushisayo kwensimbi, insimbi, ukuhola nezinye izinto zensimbi. izinga lokushisa eliphakeme, i-graphite ibe yizingqimba;
3. Lubricity: i-lubrication ukusebenza kwe-graphite incike kubukhulu be-graphite flake, i-flake, i-coefficient yokushayisana incane, ukusebenza kwe-lubrication kungcono;
4. ukuzinza kwamakhemikhali: i-graphite ekamelweni lokushisa inokuqina okuhle kwamakhemikhali, ukumelana ne-asidi, ukumelana kwe-alikhali kanye nokumelana ne-organic solvent corrosion;
5. I-plasticity: ukuqina kwe-graphite kuhle, kungachotshozwa kube yishidi elincanyana kakhulu;
6. ezishisayo ukushaqeka ukumelana: i-graphite ekamelweni lokushisa lapho isetshenziswa ingamelana nezinguquko ezinkulu ekushiseni ngaphandle kokulimala, ukushintsha kwezinga lokushisa, ivolumu ye-graphite ishintsha kancane, ngeke iqhekeke.
1. ukuhlaziywa kokuqanjwa: i-carbon elungisiwe, umswakama, ukungcola, njll .;
Ukuhlolwa kokusebenza komzimba: ubulukhuni, umlotha, i-viscosity, ubucayi, usayizi wezinhlayiyana, volatilization, amandla adonsela phansi athile, indawo ethile yendawo, iphuzu lokuncibilika, njll.
3. ukuhlolwa kwezakhiwo zomshini: ukuqina, ukuqina, ukuhlolwa kokugoba, ukuhlolwa kokuqina;
Ukuhlolwa kokusebenza kwamakhemikhali: ukumelana namanzi, ukuqina, i-asidi nokumelana ne-alkali, ukumelana nokugqwala, ukumelana nesimo sezulu, ukumelana nokushisa, njll.
5. Ezinye izinto zokuhlola: ukuqhutshwa kukagesi, ukuqhuba okushisayo, ukuthambisa, ukuzinza kwamakhemikhali, ukumelana nokushaqeka okushisayo
