Budada Graphite waa nooc ka mid ah walxaha budada ah ee ka samaysan kaarboon ka dib markii heerkulka sare ee pyrolysis ama carbonization, iyo qaybteeda ugu muhiimsan waa kaarboon. Budada graphite waxay leedahay qaab dhismeed gaar ah, kaas oo ah madow cawl ama madow khafiif ah. Miisaanka unugyadu waa 12.011.
Tilmaamaha budada graphite waxaa lagu soo koobi karaa sida soo socota:
1. Dhaqdhaqaaq sare oo sarreeya iyo kuleylka kuleylka: budada graphite waa wax-qabad wanaagsan oo kuleyl ah, oo leh dabeecad heer sare ah oo kuleyl ah. Tani waxay inta badan sabab u tahay habaynta adag iyo qaab dhismeedka lakabka ah ee atamka kaarboon ee graphite, taas oo u sahlaysa electrons iyo kulaylku inay qabtaan.
2. Wanaagsanaan la'aanta kiimikada: budada graphite waxay leedahay xasillooni kiimiko wanaagsan iyo firfircooni la'aan xaaladaha caadiga ah, oo aan ka falcelinin walxaha badankood. Tani waa sidoo kale sababta budada graphite si weyn loogu isticmaalo beeraha elektiroonigga ah iyo walxaha kiimikada, ilaalinta daxalka heerkulka sare, iwm.
3. Waxay leedahay awood farsamo oo gaar ah: marka la barbardhigo walxaha kale ee nano-nano, budada graphite waxay leedahay iska caabin saameyn sare leh, caabbinta extrusion iyo iska caabinta dillaaca, taas oo kor u qaadi karta sifooyinka farsamada ee alaabta ilaa xad.
Hababka diyaarinta budada graphite way kala duwan yihiin, hababka caadiga ah waa sida soo socota:
1. Pyrolysis heerkulka sare: kulaylka graphite dabiiciga ah ama kiimikaad farsamaysan graphite crystal heerkul sare (ka sarreeya 2000 ℃) si ay u jajabiso budada graphite.
2. Habka kaarboonaynta heerkulka sare: budada graphite waxaa lagu helaa fal-celin kiimikaad ee graphite oo leh alaab cayriin oo leh qaab dhismeed la mid ah graphite. Marka loo eego alaabta ceeriin ee kala duwan, waxaa loo qaybin karaa habab diyaarin oo kala duwan, sida kaydinta uumiga kiimikada, pyrolysis iyo carbonization.
3. Habka makaanikada: iyada oo loo marayo qashinka farsamada iyo hawlgallada baarista, garaafyada dabiiciga ah ama qalabka garaafka synthetic ayaa lagu farsameeyaa si loo helo budada garaafka.
Hababka diyaargarowga kala duwan ayaa saameyn kala duwan ku leh tayada, nadiifnimada iyo qaab-dhismeedka budada graphite. Codsiyada wax ku oolka ah, hababka diyaarinta ku habboon ayaa loo baahan yahay in lagu doorto shuruudo kala duwan.
1. Qalabka elektaroonigga ah iyo kiimikooyinka: budada graphite waxaa loo diyaarin karaa isku-dhafka polymer conductive iyo kulaylka, kuwaas oo loo isticmaalo qalabka elektarooniga ah, baytariyada, khadadka korantada iyo meelaha kale. Tusaale ahaan, qalabka elektiroonigga ah, budada graphite waxay kordhin kartaa dhaqdhaqaaqa walxaha, hagaajinta waxqabadka korantada ee korantada, waxayna kordhisaa nolosha adeegga batteriga.
2. Qalabka dahaarka: budada graphite waxaa loo isticmaali karaa diyaarinta dahaaryo kala duwan, sida daahan ka-hortagga-daxalka, daahan kulaylka kuleyl, daahan gaashaan electromagnetic, iwm ee beeraha baabuurta, diyaaradaha, dhismaha, iwm. budada graphite waxay hagaajin kartaa iska caabbinta ultraviolet iyo iska caabbinta daxalka ee alaabta.
3. Catalyst: Budada Graphite waxaa loo isticmaali karaa diyaarinta kicinta, waxaana si weyn loogu isticmaalaa isku-dhafka organic, wax soo saarka kiimikada iyo beeraha kale. Tusaale ahaan, hydrogenation ee saliidda khudradda, budada graphite ka dib daaweynta waxaa loo isticmaali karaa kicin si loo hagaajiyo xulashada falcelinta iyo dhalidda.
4. Qalabka dhoobada: Diyaarinta qalabka dhoobada, budada graphite waxay hagaajin kartaa xooggeeda farsamada iyo sifooyinka kale iyada oo loo marayo xoojinta xoojinta. Gaar ahaan cermets iyo ceramics dalool, budada graphite si weyn ayaa loo isticmaalaa.
