Ningheda Waxyaabaha Graphite Faa'iidooyinka
1.Graphite wax ceeriin ah wuxuu leeyahay cufnaan badan oo ballaaran iyo hoos u dhac yar, taas oo iska caabineysa nabaad-guurka dareeraha aluminiumka dhalaalay iyo walxaha aluminium gaaska leh illaa heerka ugu weyn.
Waxyaabaha ceeriin ee 2.Graphite oo leh daahirsanaan sare, ash ash hooseeya waxay ka hortageysaa walxaha isbeddelaya ee wax soo saarka, ka fogaanshaha dhibcaha, godadka ku duuban filimka aluminium, kaas oo damaanad qaadi kara tayada filimka aluminium dahaarka leh.
Qalabka loo yaqaan 'Graphite crucible' wuxuu leeyahay cabir sax ah, dusha sare oo siman, adkeysi qiijiid xoog leh, adeegsi hooseeya iyo nolol dheer.

Faa'iidooyinka garaafka looxa loogu talagalay lakabka uumiga ee aluminium
1. Degganaanta kuleylka: Marka loo eego xaaladaha isticmaalka garaafka iskudhafka ah ee kululaynta iyo qaboojinta degdegga ah, qaabeyn gaar ah ayaa loo sameeyaa si loo hubiyo kalsoonida tayada;
2. Iska caabinta daxalka: Isku-shaandhaynta iyo naqshadeynta jaantuska wanaagsan ayaa dib u dhigaysa daxalka meeriska
3. Saamaynta saamaynta: Awoodda naxdinta kuleylka ee garaafka la ruxruxo uu adkeysan karo waa mid aad u sarreeya, sidaa darteed geeddi-socod kasta waxaa lagu fulin karaa kalsooni;
4. Acid iska caabinta: ku darista qalabka qaaska ah waxay si weyn u wanaajineysaa tayada iskutallaabyada garaafka, waxay leedahay waxqabad aad u wanaagsan marka la eego tilmaamayaasha caabbinta aashitada, waxayna si weyn u dheereysaa nolosha adeegga ee loo yaqaan 'graphite crucibles';
5. Qabsashada kuleylka sare: Waxyaabaha sare ee kaarboonku waxay xaqiijineysaa habsami u socodka kuleylka, wuxuu gaabiyo waqtiga kala-baxa, wuxuuna si weyn u yareeyaa isticmaalka shidaalka ama isticmaalka kale ee tamarta;
6. Xakamaynta wasakheynta biraha: Xakamaynta adag ee ka kooban walxaha waxay xaqiijineysaa in garaafka garaafku uusan wasakheyn birta inta lagu jiro kala-baxa;
7. Xasiloonida tayada: Nidaamka farsamada iyo nidaamka hubinta tayada habka sameynta cadaadiska sare ayaa si buuxda u damaanad qaadaya xasiloonida tayada.
