Garaafka synthetic waa polycrystalline oo la mid ah crystallography. Waxaa jira noocyo badan oo garaaf ah oo macmal ah iyo habab wax soo saar oo kala duwan.
Dareen ballaadhan, dhammaan qalabka garaafyada ee la helay ka dib carbonization of organic organic iyo graphitization heerkulka sare waxaa si wadajir ah loo tixraaci karaa garaafyada macmal ah, sida carbon (graphite) fiber, pyrolytic carbon (graphite), graphite xumbo, iwm.
Dareenka cidhiidhiga ah, garaafyada macmalka ah sida caadiga ah waxaa loola jeedaa alaabta adag ee bulk, sida graphite electrode, graphite isostatic, oo lagu sameeyay baking, isku dhafka, qaabeynta, carbonization (oo loo yaqaan dubista warshadaha) iyo garaafka, oo leh waxyaabo wasakh ah oo hooseeya oo ah alaabta ceeriin ee dhuxusha. (coke petroleum, coke asphalt, iwm.) sida wadar ahaan, garoon dhuxul sida xidhaha.
Waxaa jira noocyo badan oo garaafyada macmalka ah, oo ay ku jiraan budada, fiber iyo block, halka dareenka cidhiidhiga ah ee garaafiga macmalka ah uu caadi ahaan xanniban yahay, kaas oo u baahan in loo habeeyo qaab gaar ah marka la isticmaalo. Waxaa loo arki karaa sida nooc ka mid ah walaxaha badan, oo ay ku jiraan wajiga graphite bedelay by qaybo kaarboon sida batroolka kookaha ama asphalt coke, wajiga graphite bedelay bynder garoonka dhuxusha dahaarka leh agagaarka qaybaha, ururinta qayb ama daldaloolada ay samaysay dhuxusha binder ka dib daawaynta kulaylka, iwm. Guud ahaan marka loo eego, sare u kaca heerkulka daaweynta kulaylka, heerka sare ee garaafka garaafka. Wax soo saarka warshadaha ee garaafka macmalka ah, heerka garaafka sida caadiga ah waa wax ka yar 90%.
Marka la barbardhigo garaafyada dabiiciga ah, garaafyada macmalka ah ayaa leh wareejinta kulaylka daciifka ah iyo korantada korantada, dufanka iyo caagagga, laakiin graphite-ka macmalka ah ayaa sidoo kale leh caabbinta xirashada, caabbinta daxalka iyo qulqulka hooseeya marka loo eego graphite dabiiciga ah.
Qalabka cayriin ee soo saarista garaafyada macmalka ah inta badan waxaa ka mid ah coke petroleum, coke irbad, coke asphalt, garoonka dhuxusha, microspheres kaarboon, iwm sarifle iyo wixii la mid ah.
Codsiga badeecada garaafiga macmalka ah ayaa inta badan ka muuqda dhinacyada soo socda:
1. Graphite electrode: Iyada oo kookaha batroolka iyo coke irbadda ay yihiin alaab cayriin ah iyo garoonka dhuxusha oo ah binder, graphite electrode waxa lagu sameeyaa calcination, batching, qas, cadaadin, dubayn, qalabayn iyo mashiin. Waxaa si weyn loogu isticmaalaa birta foornada korontada, silicon warshadaha, fosfooraska jaalaha ah iyo qalab kale iyadoo la sii daayo tamarta korantada ee qaabka arc si loo kululeeyo loona dhalaaliyo kharashka.
2. Pre-la dubay anode: ka samaysan coke batroolka sida alaabta ceeriin iyo garoon dhuxul sida binder iyada oo calcination, Duubista, qaso, riixaya, dubay, impregnation, graphitization iyo machining, waxaa guud ahaan loo isticmaalaa sida anode conductive ee qalabka aluminium electrolytic.
3. Gawaarida, giraanta xidhitaanka: gudbinta qalabka warbaahinta ee xunxun, garaafyada macmalka ah ee si ballaaran loo isticmaalo oo laga sameeyay giraangiraha piston, xirmooyinka xirmooyinka iyo xirmooyinka, shaqada iyada oo aan lagu darin saliid saliid.
4. Heat beddelka, fasalka filter: graphite macmal ah wuxuu leeyahay sifooyin caabbinta daxalka, conductivity kaamerada wanaagsan iyo permeability hoose. Waxaa si weyn loogu isticmaalaa warshadaha kiimikada si loo sameeyo kulaylka beddelka, taangiga falcelinta, nuuga, filter iyo qalab kale.
5. Garaafyada gaarka ah: oo leh kookaha batroolka oo tayo sare leh sida alaabta ceeriin, garoon dhuxul ama xabagta synthetic sida binder, iyada oo loo marayo diyaarinta alaabta ceeriin, dufan, cajiin, cadaadis, burburin, cajiin isku qasan, qaabaynta, duban badan, dhexgalka badan, sifaynta iyo graphitization, Mashiinka iyo samaynta, guud ahaan ay ku jiraan garaafka isostatic, garaafiga nukliyeerka, garaafka nadiifka sare, oo loo isticmaalo hawada, elektiroonigga, qaybaha warshadaha nukliyeerka.
