I-graphite powder iwuhlobo lwe-powder ecolekile eyenziwe ngekhabhoni ngemuva kwe-pyrolysis yezinga lokushisa eliphezulu noma i-carbonization, futhi ingxenye yayo eyinhloko yikhabhoni.Impushana ye-graphite inesakhiwo esinezingqimba esiyingqayizivele, esimpunga emnyama noma emnyama ngokukhanyayo.Isisindo sayo samangqamuzana ngu-12.011.
Izici ze-graphite powder zingafingqwa ngale ndlela elandelayo:
1. I-conductivity ephezulu kanye ne-thermal conductivity: i-graphite powder iyinto enhle yokuhambisa kanye ne-thermal conductivity, ene-conductivity ephezulu yokushisa kanye ne-conductivity.Lokhu kubangelwa ikakhulukazi ukuhlelwa okuqinile kanye nesakhiwo esinezingqimba zama-athomu e-carbon ku-graphite, okwenza kube lula ngama-electron nokushisa ukuqhuba.
2. I-inertness enhle yamakhemikhali: i-graphite powder inokuzinza okuhle kwamakhemikhali kanye nokungabi nalutho ngaphansi kwezimo ezijwayelekile, futhi ayiphenduli ngezinto eziningi.Yingakho futhi i-graphite powder isetshenziswa kabanzi emkhakheni wezinto ze-elekthronikhi namakhemikhali, ukuvikelwa kokugqwala kokushisa okuphezulu, njll.
3. Inamandla athile omshini: uma kuqhathaniswa namanye ama-nano-materials, i-graphite powder inokumelana nomthelela ophezulu, ukumelana nokukhishwa kwe-extrusion kanye nokumelana nokuqhekeka, okungathuthukisa izakhiwo zemishini yezinto zokwakha ngezinga elithile.
Izindlela zokulungiselela i-graphite powder zihlukahlukene, futhi izindlela ezivamile zimi kanje:
1. I-Pyrolysis ekushiseni okuphezulu: ukushisa i-graphite yemvelo noma ikristalu ye-graphite eyenziwe ngamakhemikhali kuya ekushiseni okuphezulu (ngaphezulu kuka-2000 ℃) ukuyibolisa ibe yimpushana yegraphite.
2. Indlela ye-carbonization yokushisa ephezulu: i-graphite powder itholakala ngokusabela kwamakhemikhali e-graphite ngezinto zokusetshenziswa ezinesakhiwo esinezingqimba ezifana ne-graphite.Ngokwezinto zokusetshenziswa ezahlukahlukene, ingahlukaniswa ngezindlela ezahlukahlukene zokulungiselela, njenge-vapor chemical vapor deposition, i-pyrolysis kanye ne-carbonization.
3. Indlela yemishini: ngokusebenzisa ukugaya kwemishini kanye nokusebenza kokuhlola, i-graphite yemvelo noma izinto ze-graphite zokwenziwa zicutshungulwa ukuze kutholwe i-graphite powder.
Izindlela ezihlukene zokulungiselela zinemiphumela ehlukene kwikhwalithi, ubumsulwa kanye ne-morphology ye-graphite powder.Ekusetshenzisweni okungokoqobo, izindlela zokulungiselela ezifanele zidinga ukukhethwa ngokuvumelana nezidingo ezahlukene.
1. Izinto ze-elekthronikhi kanye namakhemikhali: i-graphite powder ingalungiswa ibe yizinhlanganisela ze-polymer conductive ne-thermal conductive, ezisetshenziswa kumadivayisi kagesi, amabhethri, ama-inki e-conductive kanye nezinye izinkambu.Isibonelo, ezintweni ze-electrode, i-graphite powder ingakhuphula ukuqhutshwa kwezinto, ithuthukise ukusebenza kwe-electrochemical ye-electrode, futhi yandise impilo yesevisi yebhethri.
2. Izinto zokumboza: i-graphite powder ingasetshenziselwa ukulungiswa kwezingubo ezihlukahlukene, njenge-anti-corrosion coating, i-thermal conductivity coating, i-electromagnetic shielding coating, njll. Emikhakheni yezimoto, izindiza, ukwakhiwa, njll. nge-graphite powder ingathuthukisa ukumelana ne-ultraviolet nokumelana nokugqwala kwezinto.
3. I-Catalyst: I-graphite powder ingasetshenziselwa ukulungiswa kwe-catalyst, futhi isetshenziswa kabanzi ekuhlanganiseni kwe-organic, ukukhiqizwa kwamakhemikhali nezinye izinkambu.Isibonelo, ku-hydrogenation yamafutha yemifino, i-graphite powder emva kokwelashwa ingasetshenziswa njenge-catalyst yokuthuthukisa ukukhetha kokusabela kanye nesivuno.
4. Izinto ze-Ceramic: Ekulungiseleleni izinto ze-ceramic, i-graphite powder ingathuthukisa amandla ayo omshini nezinye izakhiwo ngomphumela wokuqinisa.Ikakhulukazi kuma-cermets nama-ceramics ane-porous, i-graphite powder isetshenziswa kakhulu.
