Umahluko phakathi kweCarbon kunye neSilicon Carbide
Ukubunjwa kunye neSakhiwo
Iitywina zeCarbon mechanical zenziwe ngegraphite, uhlobo lwekhabhoni eyaziwa ngokuba yi-self-lubricating properties kunye nokumelana nobushushu kunye nokuhlaselwa kweekhemikhali.Igraphite idla ngokufakwa intlaka okanye isinyithi ukukhulisa iimpawu zayo zomatshini.
I-Silicon carbide (i-SiC) yimathiriyeli ye-ceramic eqinile, engagugiyo eyenziwe ngesilicon kunye nekhabhoni.Inokwakheka kwekristale enegalelo kubulukhuni bayo obugqwesileyo, ukuhanjiswa kwe-thermal, kunye nokuzinza kweekhemikhali.
Ubulukhuni kunye nokuNxitywa kweNgqondo
I-silicon carbide inzima kakhulu kunekhabhoni, kunye nobunzima be-Mohs be-9-9.5 xa kuthelekiswa ne-1-2 yegraphite.Obu bunzima buphezulu benza i-SiC ixhathise kakhulu ukunxitywa kwe-abrasive, nakwizicelo ezifunwayo ezinemithombo yeendaba ezirhabaxa.
Izitywina zeCarbon, ngelixa zithambile, zisabonelela ngokumelana nokunxiba kakuhle kwiindawo ezingezizo.Ubume bokuzithambisa begraphite bunceda ekunciphiseni ukukhuhlana kunye nokuguga phakathi kobuso betywina.
Ukumelana nobushushu
Zombini i-carbon kunye ne-silicon carbide zineempawu ezibalaseleyo zobushushu obuphezulu.Iitywina zeCarbon zinokusebenza kumaqondo obushushu ukuya kuma-350°C (662°F), ngelixa i-silicon carbide seals inokumelana namaqondo obushushu aphezulu, adla ngokugqitha kuma-500°C (932°F).
I-thermal conductivity ye-silicon carbide iphezulu kunekhabhoni, ivumela izitywina ze-SiC ukuba zichithe ubushushu ngokufanelekileyo kwaye zigcine ubushushu obuphantsi bokusebenza kwindawo yokutywina.
Ukumelana nemichiza
I-Silicon carbide i-inert yekhemikhali kwaye iyamelana nokuhlaselwa kwii-asidi ezininzi, iziseko, kunye nezinyibilikisi.Lolona khetho lubalaseleyo lokutywina imidiya eyingozi kakhulu okanye enobundlobongela.
Ikhabhoni ikwabonelela ngokumelana neekhemikhali ezilungileyo, ngakumbi kwiikhompawundi ze-organic kunye ne-non-oxidizing acids kunye neziseko.Nangona kunjalo, isenokungalungeli kakhulu kwindawo ene-oxidizing okanye usetyenziso olunemidiya ephezulu ye-pH.
Iindleko kunye nokuFumana
Iitywina zoomatshini beCarbon zihlala zixabisa ngaphantsi kunezitywina zesilicon carbide ngenxa yexabiso eliphantsi lemathiriyeli ekrwada kunye neenkqubo ezilula zokwenza.Iitywina zeCarbon zifumaneka ngokubanzi kwaye zinokuveliswa kwiindidi ezahlukeneyo kunye nokucwangciswa.
