Kwiminyaka yakutshanje, itekhnoloji yemveliso yekhayaI-greyitite crucabswenze inkqubela ebonakalayo. Ababanjiwe nje ngenqanawa ethunyelweyo, kodwa kwezinye iimeko bade bagqitha kubo. Ngokuqesha ubuchwephesha bokwenza imveliso kunye nokufumana izinto ezikumgangatho ophezulu, igrafu emiselweyo ngoku inokumelana neemeko ezigqithileyo ngokungafanelekanga.
Iimpawu eziphambili zezi mpawu zegrafiti entsha azifanele zithintelwe. Okokuqala, banayo i-pumering ephezulu yokuqhubela phambili, ukunciphisa ixesha lokulila, ngenxa yokusetyenziswa kwezinto ezingafunekiyo ezinjengegrafu, eyenza igrafu egqwesileyo. Oku kunyuka ngokusebenza kwempumelelo kungekuphela nje kukugcina ixesha namandla, kodwa ukwandisa imveliso kumashishini.
Ukongeza, ezi zinto zibethelekayo zinokuchasana nobushushu kwaye zinokumelana namaqondo obushushu ukuya kuthi ga kwi-1200 ukuya kwi-1600 ° C. Olu phawu lubalaseleyo luyenza ilungele ukusetyenziswa kwezicelo ezifuna amaqondo obushushu aphezulu, anjengeenkcazelo yensimbi kunye neziseko. Amandla okumelana nobushushu obuthe gabalala ngaphandle kokusebenza komsebenzi ngumdlalo wemizi-mveliso.
Enye yezona ndawo zimangalisayo zezi phofu zinqabileyo kukungaxhathisi. Babonisa ukuxhathisa okukhulu nangaphantsi kobuso bezixhobo ezinobungozi kakhulu, ukuqinisekisa ukuba i-longeving kunye nentsebenzo ephuculweyo. Ukuxhathisa okusulwayo kuyanda kuluhlu lwezicelo ezibethelele, ngakumbi kumashishini ekhemikhali kunye nemizi yentsimbi.
Ukongeza, ukungavisisani kwayo okuthe tyaba kukwenza kube nkulu kwiimveliso ezifanayo. I-grafite the the thercabs ibonisa i-elasticity ephantsi kwe-piding yokuphola kunye nokutshisa, ibetha ukuba ichaphazeleke ekrameni kunye nokuqhawula. Olu ncedo luphezulu aluphuculi nje ukhuseleko kodwa likwabonelela ngolondolozo lweendleko olubalulekileyo ngokunciphisa isidingo sokutshintsha rhoqo.
Igrafu ye-greyitite isetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yokuqhubela phambili kwabo okuhle kunye nokuchaswa kobushushu obuphezulu. Ezi zinto zibethelayo zinelungelo lokufumana ulwandiso lwe-shirmal kwaye ziyanyangeka kutshintsho lweqondo. Banokumelana ngokukhawuleza nokufudumeza kunye nokupholisa ngaphandle kokubandezeleka okukhulu, ukuqinisekisa ukusebenza ngokufanelekileyo kunye nokuthembeka.
Igrafu ye-greyitives ingumzekelo wokunganyangeki kwe-acidic kunye ne-alkaline sombuso, ibenza babalulekile kwiilebhu kunye nezityalo zemveliso yemichiza. Uzinzo lwabo olugqibeleleyo lokuphendula kweekhemikhali lubonisa ukuqina kwabo kwaye lunokuphatha ngokukhuselekileyo uluhlu olubanzi lweekhemikhali.
Ukuqulunqwa kwegraphite ityetyiswa igrafu yendalo njengeyona nto iphambili. Ibanjwe kunye esebenzisa i-adhesive ekhethekileyo ebizwa ngokuba yiplastiki yomlilo. Olu hlanganiso lukhethekileyo luqinisekisa ukuba iimbeke ezithe tye igcina ukuthembeka kwesakhiwo phantsi kweemeko ezinzima, ukubonelela ngeziphumo ezingaguqukiyo kwizicelo ezahlukeneyo.
Ukufika kwezemisebenzi eveliswe ngegrafikhi yegrafired ayiphawuli kuphela i-upocuguegical yezobuchwephesha, kodwa ikwaxhasa ukuphuculwa kwamashishini endawo. Imveliso yemveliso yaseKhaya, ekumgangatho okuphakathi ukunciphisa ukuthembela kunyango ngelixa kubonelela ngamaxabiso okhuphiswano kuluhlu lwamashishini. Olu phuhliso lubamba indlela yokufumana imali enkulu kwaye yomeleze imveliso yelizwe.
Kwisishwankathelo, izinto ezintsha kwimveliso yegrafu esityebileyo siye sayityumza ukuya kwiindawo eziphakamileyo, ezigqithileyo ezingenantsingiselo ezingeniswayo ngokwendlela yokusebenza kunye nokuqina. Ukuqhutywa kwengqondo okuhle, ukumelana nobushushu obuhle, ukuxhathisa ubushushu kunye nokuxhathisa isothuso sentshukumo kwenza ukuba kubalulekile kwizicelo ezahlukeneyo zemizi-mveliso. Ngeenkqubela phambili, ishishini elityebileyo lemifanekiso lenze iminikelo ebalulekileyo ekukhuleni kwemveliso yeli lizwe kunye nokuzithemba.
