I-graphite, uhlobo lwekhabhoni, yinto ephawulekayo eyaziwayo ngeempawu zayo ezizodwa kunye noluhlu olubanzi lwezicelo.Iintonga zegraphite, ngokukodwa, baye bazuza ukuqondwa okuphawulekayo ngeempawu zabo ezikhethekileyo kunye nokuguquguquka. Ngokuqhuba kwabo kakuhle kwe-thermal, ukuhanjiswa kombane, kunye namandla omatshini,iintonga zegraphiteibe lukhetho olukhethwayo kumashishini ahlukeneyo. Kweli nqaku, siza kuphonononga iimpawu ezibalaseleyo zeiintonga zegraphitekunye nezicelo zabo ezahlukeneyo.
Enye yeenzuzo eziphambili zeiintonga zegraphitekukuqhuba kwabo okukhethekileyo kwe-thermal. I-graphite ibonisa i-conductivity ephezulu ye-thermal ngenxa yesakhiwo sayo esisodwa se-athomu, esivumela ukushisa ukuba kudluliselwe ngokukhawuleza kwizinto eziphathekayo. Le propati yenzaiintonga zegraphiteesebenza kakhulu kwizicelo ezifuna ukuchithwa kobushushu okusebenzayo, njengakwiindawo zokutshintsha ubushushu, kwiziko, kunye neenkqubo zolawulo lobushushu. I-conductivity ephezulu ye-thermal ye-graphite rods ibenza bakwazi ukusabalalisa ukushisa ngokulinganayo, ukukhusela iindawo ezishushu zendawo kunye nokuqinisekisa ukusebenza kakuhle kwizicelo zokushisa.
Iintonga zegraphitezikwanazo nokuqhutywa kombane okugqwesileyo, okubenza baxabiseke kusetyenziso lombane kunye ne-elektroniki. Isakhiwo se-athomu esiyingqayizivele se-graphite sivumela ukuhamba ngokukhululekileyo kwee-electron, kube lula ukuhamba kombane. Le propati yenza ukuba iirodi zegraphite ziqhube umbane ngokufanelekileyo, zizenze zilungele ukusetyenziswa ezifana ne-electrode, uqhagamshelwano lombane, kunye nezinto eziphethe umsinga. I-conductivity ephezulu yombane yee-graphite rods iqinisekisa ukuchasana okuncinci kunye nokulahlekelwa kwamandla, okunegalelo ekusebenzeni kakuhle kunye nokuthembeka kweenkqubo zombane.
Ukongeza kwi-conductivity yabo ye-thermal kunye nombane, iintonga zegraphite zibonisa iimpawu eziphawulekayo zomatshini. Banendibaniselwano yamandla aphezulu kunye noxinaniso oluphantsi, okubenza ukuba bakhaphukhaphu kodwa bomelele. Iintonga zegraphite zinamandla okuqina okuchukumisayo, ezivumela ukuba zimelane nemithwalo ephezulu kunye noxinzelelo lomatshini. La mandla omatshini enza ukuba iintonga zegraphite zilungele ukusetyenziswa kwezakhiwo kumashishini afana ne-aerospace, i-automotive, kunye nokwakhiwa. Zingasetyenziswa kumacandelo afuna ukomelela kunye nokukhaphukhaphu, njengamalungu enqwelomoya, izixhobo zemidlalo, kunye nezinto zokuqinisa kwizakhiwo.
Enye ipropati ephawulekayo yeentonga zegraphite kukunganyangeki kwabo kweekhemikhali. Igraphite inert kakhulu kwaye ibonisa ukumelana okugqwesileyo kuluhlu olubanzi lweekhemikhali, iiasidi, kunye nezinyibilikisi. Oku kuxhathisa ukuhlaselwa kweekhemikhali kwenza iintonga zegraphite zilungele ukusetyenziswa kwiindawo ezinobungozi, ezifana nokulungiswa kweekhemikhali, i-electroplating, kunye nokucocwa kwamanzi amdaka. Ukuzinza kweekhemikhali kweentonga zegraphite kuqinisekisa ukuba zihlala ixesha elide kunye nokuthembeka kwazo, nakwiimeko zekhemikhali ezinzima.
Iintonga zegraphite zikwabonelela ngeempawu ezilungileyo zokuthambisa ngenxa yokwakheka kweathomu yazo. Amandla e-interlayer abuthathaka kwigraphite avumela iileya ukuba zityibilike ngokutyibilikayo komnye nomnye, zinciphisa ukungqubana kunye nokuguga. Olu phawu lokuzithambisa lwenza ukuba iirodi zegraphite zibe lukhetho oluhle kakhulu kwizicelo ezibandakanya izinto ezityibilikayo okanye ezijikelezayo, ezinje ngeebheringi, izitywina, kunye neendibano zoomatshini. Iimpawu zokuthambisa zeerodi zegraphite zinegalelo ekunciphiseni ukukhuhlana, ixesha elide lecandelo, kunye nokuphucula ukusebenza kakuhle.
Ukuqukumbela, iirodi zegraphite zineempawu ezikhethekileyo ezenza zibe luncedo kakhulu kwiinkqubo ezahlukeneyo. Ukuqhuba kwabo okuphezulu kwe-thermal, ukuhanjiswa kombane, amandla omatshini, ukumelana neekhemikhali, kunye neempawu zokuthambisa kunegalelo ekusebenziseni kwabo ngeendlela ezahlukeneyo kumashishini afana nolawulo lwe-thermal, i-elektroniki, ukwakhiwa, kunye nokusetyenzwa kweekhemikhali. Ukongeza, iirodi zegraphite zifumana uncedo kwintsimi yezilwanyana, ngakumbi kwi-equine dentistry. Njengoko amashishini eqhubeka efuna imathiriyeli ephucukileyo kwiimfuno zabo ezahlukeneyo, iirodi zegraphite zihlala zilukhetho oluthembekileyo noluxabisekileyo, lunikezela indibaniselwano yeempawu ezinqwenelekayo ezonyusa ukusebenza, ukuqina, kunye nokusebenza kakuhle kwizicelo ezininzi.
