Iphepha le-Graphite Graphite alisetshenziselwa ukuvalwa uphawu, kepha futhi linezimpawu ezinhle kakhulu njengokuphakelayo kukagesi, ukusebenza okushisayo, ukuthambisa, ukuthambisa okuphezulu, ukumelana nokugqwala okuphansi. Ngenxa yalokhu, ukusetshenziswa kwe-graphite eguquguqukayo kubekwa iminyaka eminingi. Izinto zokufudumeza kagesi zenziwa ngokusebenza kwayo nokusebenza kwazo, futhi kulula ukucindezela uhlelo oluyinkimbinkimbi lwe-groove groove yegesi kaphethiloli kanye negesi oxidant. Umhleli we-graphite olandelayo uzophendula ukuthi kungani iphepha le-graphite graphite lingumfazi omuhle kakhulu:
Usebenzisa izici ezinhle kakhulu zokuboniswa kwephepha le-graphite eliguqukayo ekulweni kwemisebe ye-thermal, okuvikelekile okushisayo (ukufakwa) kwezinto zokushisa eziphakeme. Ngokuvuselelwa kwemisebe (> 850 ℃), i-graphite eguquguqukayo iyisitayela esihle kakhulu ngokusebenza okuzinzile okusebenzayo, okunomphumela wokuvikela kangcono kunezinsimbi ezinjenge-tungsten ne-molybdenum. I-graphite isikhathi eside isetshenziswe njenge-lubricant ephezulu yokushisa, futhi i-graphite ye-graphite evumelana nomlandeli omuhle kakhulu. Uma isetshenziswa ezimweni eziphakeme zokushisa okushisa njengokufa kwayo njengokufa kwayo, inokuthambisa okuhle kakhulu, futhi kungagwema ukuthambisa izindawo ezifile, kube nomphumela omuhle. Okunye ukusetshenziswa okusha kuyakhiwa futhi.
Iphepha le-graphite elikhiqizwa yi-graphite furuite lenziwe ngegrafu elandisiwe njengezinto ezingavuthiwe, ezingacindezelwa zibe ngephepha le-graphite elinobukhulu obukhulu ngokubeka umkhiqizi okhethekile we-graphite. Iphepha le-graphite kulula ukusika futhi lingasikwa libe yizilo ezahlukahlukene zezimpawu ze-graphite, ezingasetshenziswa emkhakheni wokubekwa uphawu kwezimboni. Ukusebenza okuhle kokubekwa uphawu kwephepha le-graphite kukwenze kwaba nedumela le- "King of Sealing", nephepha le-graphite lingasetshenziswa ekuvalweni kwezimboni zemishini, njll.
