Izinto zokufudumeza zeGraphite, njengezixhobo zokufudumeza ezisebenzisa ubushushu obuphezulu, zisetyenziswa kakhulu kumashishini amaninzi, kuquka i-metallurgy, i-electronics, i-semiconductors, kunye neekhemikhali. Izixhobo ze-graphite zinomoya ogqithisileyo wokushisa, ukumelana nobushushu obuphezulu, kunye nozinzo lweekhemikhali, nto leyo evumela ukuba zigcine ukusebenza okuzinzileyo ixesha elide, ingakumbi kwiindawo ezisebenzisa ubushushu obuphezulu. Nangona kunjalo, ubushushu obuphezulu bokusebenza bezinto zokufudumeza ze-graphite buchatshazelwa zizinto ezahlukeneyo, kunye nomahluko omkhulu kwimida yobushushu phakathi kweendawo zomoya kunye ne-vacuum.
Kwi-indawo yomoya, ubushushu obuphezulu bezinto zokufudumeza zegrafiti bunqunyelwe yi-oxidation. Xa into yokufudumeza yegrafiti ishushu kubushushu obuphezulu, isabela kunye neoksijini emoyeni ukuze yenze i-carbon dioxide (CO₂) okanye i-carbon monoxide (CO). Le nkqubo yokufudumeza ikhokelela ekuwohlokeni kwezinto kancinci kancinci kunye nokusebenza okunciphileyo, ekugqibeleni ichaphazela ubomi bento yokufudumeza. Ngokwesiqhelo, kwiimeko zomoya eziqhelekileyo, ubushushu obuphezulu bokusebenza bezinto zokufudumeza zegrafiti bujikeleze.3000°CUkudlula kolu bushushu kukhawulezisa isantya se-oxidation, nto leyo ebangela ukubola ngokukhawuleza kwezinto.
Ngokungafaniyo nomoya, kwiindawo yokufunxa umoya, i-oxidation iyacinezelwa ngempumelelo. Kwi-vacuum, uxinzelelo lwe-oksijini luphantse lube yi-zero, ngoko ke akukho i-oxidation eyenzekayo kumphezulu we-graphite. Oku kuvumela izixhobo ze-graphite ukuba zikwazi ukumelana namaqondo obushushu aphezulu kakhulu. Enyanisweni, kwi-vacuum, ubushushu obukhulu be-graphite bunokufikelela kwi-3500°Cokanye ngaphezulu, ubushushu obungenakufikelelwa emoyeni. Iingenelo zeemeko zomoya azikho kuphela kulawulo lwe-oxidation kodwa nakwizinzo ezingcono zobushushu kunye nobomi obude. Oku kwenza izinto zokufudumeza zegrafiti zilungele ukusetyenziswa kobushushu obuphezulu kakhulu, njengokwenziwa kwe-semiconductor kunye neenkqubo zokufudumeza zokuhlola isithuba, apho zihlala zisebenza kwiimeko zomoya ukuze zisebenzise ngokupheleleyo iimpawu zazo zezinto.
Ukongeza kwi-oxidation, amandla aphezulu obushushu e-graphite adlala indima ebalulekileyo ekumiseleni umda wobushushu bayo. Njengoko ubushushu busanda, i-graphite lattice inokutshintsha kancinci, ingakumbi xa ubushushu budlula uluhlu oluthile. Oku kunokubangela ukwanda kobushushu okanye ukwakheka kwemifantu yomphezulu. Olu tshintsho lwendalo aluchaphazeli kuphela iimpawu zoomatshini ze-graphite kodwa lunokunciphisa nokuzinza kobushushu bento yokufudumeza. Ke ngoko, ukuqina kwe-graphite kubushushu obahlukeneyo yinto ebalulekileyo ekumiseleni ukuba inokusebenza ngokukhuselekileyo nangokufanelekileyo na kwiindawo ezithile.
Kwimeko-bume ye-vacuum, izinto zokufudumeza ze-graphite zinokufikelela kumaqondo obushushu aphezulu kakhulu kuba akukho i-oxidation yokonakalisa izinto. Ukongeza, kwi-vacuum, ukudluliselwa kobushushu kusebenza kakuhle, njengoko i-graphite inokudlulisa ubushushu ngcono kwindawo yokusebenza ngaphandle kokuphazamiseka kwe-oxidation. Oku kwenza izinto zokufudumeza ze-graphite zilungele ukusetyenziswa kwii-vacuum oven, ukunyibilika kwe-laser, iinkqubo zokufudumeza indawo, kunye nezinye izinto ezisebenzisa amaqondo obushushu aphezulu.
Nangona kunjalo, nangona kukho iingenelo ezibalulekileyo kwindawo yokukhupha umoya, kufuneka kuqwalaselwe ezinye izinto xa kusetyenziswa izinto zegrafiti kwi-vacuum. Umzekelo, ukuhanjiswa kobushushu begrafiti kunokutshintsha kancinci ngenxa yokutshintsha koxinzelelo lwegesi. Ke ngoko, ulawulo lobushushu lwezinto zokufudumeza zegrafiti kwiimeko ezahlukeneyo ze-vacuum lusafuna ukulungiswa ngokusekelwe kwiimeko ezithile. Ukongeza, nangona i-oxidation ithintelwa kwi-vacuum, iimeko ezigqithisileyo ezifana nokukhutshwa kwe-arc zisenokuchaphazela uzinzo kunye nokuqina kwegrafiti.
Ngamafutshane, umahluko kwimida yobushushuizinto zokufudumeza zegrafayithiKwindawo ezishushu emoyeni nakwi-vacuum kubonakalisa unxibelelwano oluntsonkothileyo phakathi kweempawu zezinto kunye nezinto ezingqongileyo. I-oxidation emoyeni yeyona nto iphambili ethintela uzinzo lwe-graphite kumaqondo obushushu aphezulu, ngelixa indawo eshushu emoyeni ibonelela ngeqonga elingena-oxidation phantse, elivumela i-graphite ukuba isebenze kumaqondo obushushu aphezulu kakhulu. Xa ukhetha izinto zokufudumeza ze-graphite kwizicelo ezithile, kubalulekile ukuqwalasela indawo yokusebenza ukuze uthathe isigqibo sokuba uza kusebenzisa umoya okanye i-vacuum heater. Kwindawo ezishushu kakhulu nezihlala ixesha elide, izinto zokufudumeza ze-graphite kwiindawo ezishushu ngokuqinisekileyo ziluncedo ngakumbi.
