1. Ishishini lesinyithi
Kwishishini lesinyithi, umgubo wegrafiti yendalo ungasetyenziselwa ukuvelisa izinto ezirhabaxa ezifana nezitena ze-magnesium carbon kunye nezitena ze-aluminium carbon ngenxa yokumelana kwayo kakuhle ne-oxidation. Umgubo wegrafiti yokwenziwa ungasetyenziswa njenge-electrode yokwenza intsimbi, kodwa i-electrode eyenziwe ngomgubo wegrafiti yendalo kunzima ukuyisebenzisa kwisithando sombane sokwenza intsimbi.
2. Ishishini loomatshini
Kwishishini loomatshini, izinto zegrafiti zihlala zisetyenziswa njengezinto ezimelana nokuguguleka kunye nokuthambisa. Izinto zokuqala ezikrwada zokulungiselela igrafiti enokukhuliswa yigrafiti enekhabhoni eninzi, kwaye kusetyenziswa ezinye izinto ezisetyenziswa ngamakhemikhali ezifana ne-sulfuric acid egxininisiweyo (ngaphezulu kwe-98%), i-hydrogen peroxide (ngaphezulu kwe-28%), i-potassium permanganate kunye nezinye izinto ezisetyenziswa ngamashishini. Amanyathelo aqhelekileyo okulungiselela ngala alandelayo: kubushushu obufanelekileyo, umlinganiselo owahlukileyo wesisombululo se-hydrogen peroxide, i-natural flake graphite kunye ne-concentrated sulfuric acid zongezwa kwiinkqubo ezahlukeneyo, kwaye zisabela ixesha elithile phantsi koxinzelelo oluqhubekayo, emva koko zihlanjwe zibe zihlukanisiweyo, zihlukaniswe nge-centrifugal, ziphelelwe ngamanzi emzimbeni kwaye zomiswe nge-vacuum kwi-60 ℃. Umgubo wegrafiti yendalo unamafutha afanelekileyo kwaye uhlala usetyenziswa njengesongezelelo kwioyile yokuthambisa. Ukuhambisa i-medium ebolayo, iiringi zepiston, iiringi zokutywina kunye neebheringi ezenziwe ngomgubo wegrafiti yokwenziwa zisetyenziswa kakhulu, ngaphandle kokongeza ioyile yokuthambisa xa zisebenza. Umgubo wegrafiti yendalo kunye nee-polymer resin composites nazo zingasetyenziswa kwiindawo ezingasentla, kodwa ukumelana nokuguguleka akulunganga njengomgubo wegrafiti yokwenziwa.
3. Ishishini leekhemikhali
Umgubo wegrafiti yokwenziwa uneempawu zokuxhathisa ukugqwala, ukuqhuba kakuhle kobushushu, ukungena kancinci, kwaye usetyenziswa kakhulu kwishishini leekhemikhali ukwenza umtshintshi wobushushu, itanki yokusabela, inqaba yokufunxa, isihluzi kunye nezinye izixhobo. Umgubo wegrafiti yendalo kunye nezixhobo ze-polymer resin nazo zingasetyenziswa kwiindawo ezingasentla, kodwa ukuqhubela phambili kobushushu kunye nokugqwala akulunganga njengomgubo wegrafiti yokwenziwa.
Ngophuhliso lwetekhnoloji yophando, amathuba okusetyenziswa komgubo wegrafiti yokwenziwa akanakulinganiswa. Okwangoku, ukusebenzisa igrafiti yendalo njengezinto zokwenza imveliso yegrafiti yokwenziwa kunokubonwa njengenye yeendlela ezibalulekileyo zokwandisa intsimi yokusebenza kwegrafiti yendalo. Umgubo wegrafiti yendalo usetyenzisiwe njengezinto ezincedisayo ekuvelisweni komgubo wegrafiti yokwenziwa, kodwa akwanelanga ukuphuhlisa iimveliso zegrafiti yokwenziwa kunye nomgubo wegrafiti yendalo njengezinto eziphambili zokwenza imveliso. Eyona ndlela ilungileyo yokufezekisa le njongo kukusebenzisa ngokupheleleyo isakhiwo kunye neempawu zomgubo wegrafiti yendalo, kunye nokuvelisa iimveliso zegrafiti yokwenziwa ezinesakhiwo esikhethekileyo, ukusebenza kunye nokusetyenziswa ngobuchwepheshe obufanelekileyo, indlela kunye nendlela.
