I-graphite powder yinto ezwela kakhulu ekuphenduleni kwamakhemikhali.Ezimweni ezihlukene, ukumelana kwayo kuzoshintsha, okusho ukuthi inani layo lokumelana lizoshintsha.Nokho, kunento eyodwa engashintshi.I-graphite powder ingenye yezinto ezinhle ezingezona ezensimbi.Uma nje i-graphite powder igcinwa ingaphazamiseki entweni evalekile, izophinde ifakwe ugesi njengocingo oluncane.Kodwa-ke, ayikho inombolo enembile yenani lokumelana, Ngenxa yokuthi ubukhulu be-graphite powder buyahlukahluka, inani lokumelana ne-graphite powder lizophinde lihluke lapho lisetshenziselwa izinto ezahlukene kanye nezindawo.Ngenxa yesakhiwo sayo esikhethekile, i-graphite inezindawo ezikhethekile ezilandelayo:

1) Uhlobo olumelana nokushisa okuphezulu: indawo encibilikayo yegraphite ingu-3850 ± 50 ℃, futhi indawo yokubilisa ingu-4250 ℃.Ngisho noma kushiswa i-arc yokushisa ephezulu kakhulu, ukulahlekelwa isisindo kanye ne-coefficient yokwandisa okushisayo kuncane kakhulu.Amandla egraphite akhuphuka ngezinga lokushisa, futhi ngo-2000 ℃, amandla egraphite aphinda kabili.
I-2) I-Conductivity kanye ne-thermal conductivity: I-conductivity ye-graphite iphindwe izikhathi ezingu-100 kunaleyo yamaminerali angewona ama-metallic avamile.I-thermal conductivity idlula leyo yezinto zensimbi ezifana nensimbi, insimbi, nomthofu.I-conductivity eshisayo iyancipha ngokukhuphuka kwezinga lokushisa, futhi ngisho namazinga okushisa aphezulu kakhulu, i-graphite iba isivikeli.
3) I-Lubricity: Ukusebenza kokugcoba kwe-graphite kuncike kusayizi wama-graphite flakes.Uma ama-flakes emakhulu, i-coefficient ye-friction iba mancane, kanye nokusebenza okungcono kokugcotshwa.
I-4) Ukuzinza kwamakhemikhali: i-graphite inokusimama okuhle kwamakhemikhali ekamelweni lokushisa, futhi ingamelana ne-asidi, i-alkali ne-organic solvent corrosion.
I-5) Ipulasitiki: I-graphite inokuqina okuhle futhi ingaxhunywa kumashidi amancane kakhulu.
I-6) Ukumelana nokushisa okushisayo: I-graphite ingakwazi ukumelana nezinguquko ezinzima zokushisa ngaphandle kokulimala lapho isetshenziswa ekamelweni lokushisa.Lapho izinga lokushisa lishintsha ngokuzumayo, umthamo we-graphite awushintshi kakhulu futhi ngeke uqhekeke.

1. Njengezinto eziphikisayo: i-graphite nemikhiqizo yayo inezindawo zokumelana nokushisa okuphezulu namandla aphezulu.Embonini ye-metallurgical, isetshenziselwa kakhulu ukwenza izinsimbi ze-graphite.Ekwenziweni kwensimbi, i-graphite ivame ukusetshenziswa njenge-ejenti evikelayo yezinsimbi zensimbi kanye nolwelwesi lwesithando somlilo se-metallurgical.
2. Njengempahla eqhubayo: esetshenziswa embonini kagesi ukwenza ama-electrode, amabhulashi, ama-carbon rod, amashubhu ekhabhoni, ama-electrode aqondile ama-mercury positive current transformers, ama-graphite gaskets, izingxenye zocingo, okokunamathela kumashubhu kamabonakude, njll.
3. Njengento yokugcoba engagugi: I-graphite ivamise ukusetshenziswa njengesithambiso embonini yemishini.Amafutha okugcoba ngokuvamile awakwazi ukusetshenziswa ngaphansi kwezimo zesivinini esikhulu, izinga lokushisa eliphezulu, kanye nezimo zokucindezela okukhulu, kuyilapho izinto ezikwazi ukumelana ne-graphite zingasebenza ngaphandle kokugcoba uwoyela ngesivinini esishelelayo esiphezulu emazingeni okushisa asukela ku-200 kuya ku-2000 ℃.Imishini eminingi ethutha imidiya ebolayo yenziwa kabanzi ngezinto zegraphite ukwenza izinkomishi ze-piston, izindandatho zokuvala, nama-bearings, okungadingi ukufakwa kwamafutha okugcoba ngesikhathi sokusebenza.I-emulsion ye-graphite iphinde ibe yi-lubricant enhle yokucubungula insimbi eminingi (umdwebo wocingo, umdwebo weshubhu).
