Doorka Kookaha Batroolka ee Graphitized ee Warshadaha Dhalmada ee Silicon-ka Warshadaha iyo Kaarboon-ga Silicon-ka
I. Doorka Dhalmada Silikoon ee Warshadaha
1. Shaqada Wakiilka Yaraynta Aasaasiga ah
Kookaha batroolka ee sawiran waa mid ka mid ah wakiilada ugu muhiimsan ee yareeya kaarboonka ee wax soo saarka silikoonka warshadaha. Waxyaabaha ku jira kaarboonka sare (90%-97%) iyo astaamaha dambaska hooseeya waxay ka dhigayaan walxo muhiim ah oo ceeriin ah oo lagu bixiyo kaarboonka loo baahan yahay falcelinta. Inta lagu jiro dhalaalinta foornada korantada, kookaha batroolka wuxuu fududeeyaa beddelka silica (SiO₂) una beddelo silikoon warshadeed iyada oo loo marayo falcelinta dhimista kaarboonka. Intaa waxaa dheer, koontaroolkeeda korontada wuxuu ka caawiyaa nidaaminta iska caabbinta kharashka foornada, xakamaynta qoto dheer ee gelinta elektroodka iyo hagaajinta hawlgalka foornada qaansada korantada.
2. Hagaajinta Waxqabadka Kuraasta Foornada
- Hagaajinta Iska caabinta: Korantada korantada ee kookaha batroolka ayaa saameyn ku yeelata iska caabinta kharashka foornada. Iyadoo la hagaajinayo qiyaasta iyo cabbirka walxaha, hufnaanta kulaylka ee foornada qaansada korontada ayaa la hagaajin karaa, taasoo yaraynaysa isticmaalka korontada.
- Hagaajinta Joogitaanka: Kookaha batroolka saafiga ah wuxuu u janjeeraa inuu sawiro ku sameeyo heerkul sare, taasoo keenta in qoloftu ka samaysmato dusha sare ee foornada. Si loo yareeyo tan, jajabyada alwaaxa ama qoryaha ayaa la isku daraa si loo kordhiyo iska caabinta gaarka ah, loo xoojiyo u-gudbinta dallacaadda foornada, loona xasiliyo xaaladaha hawlgalka.
- Kaabis Hawlaha Kiimikada: Kookaha batroolka wuxuu muujiyaa sifooyin yareynaya oo daciif ah waxaana badanaa loo isticmaalaa iyadoo lala kaashanayo dhuxusha silikoon ee dambaska yar ama dhuxusha si loo hubiyo horumarka siman ee falcelinta dhimista.
3. Isku dheelitirka Tayada iyo Qiimaha
- Wax Soo Saarka Silikoon ee Heerka Sare ah: Dambaska yar ee ku jira kookaha batroolka ayaa ka dhigaya mid ku habboon soo saarista silikoon warshadeed oo saafi ah. Si kastaba ha ahaatee, waa in la xakameeyaa sulfur, vanadium, nikkel, iyo wasakhda kale, gaar ahaan wax soo saarka organosilicon, halkaas oo saamiga kookaha batroolka la xaddiday si looga hortago sumowga kiciyaha.
- Faa'iidooyinka Dhaqaale: Marka la barbardhigo dhuxusha, kookaha batroolka ayaa si ballaaran loo heli karaa, qiimo ahaan waa mid deggan, mana saameyn badan ku yeesho siyaasadaha deegaanka, taasoo ka dhigaysa wakiilka ugu wanaagsan ee yareeya wax soo saarka baaxadda leh.
II. Doorka Dhalmada Kaarboohaydraytka ee Silikoon
1. Bixinta Isha Kaarboonka
Soo saarista silikoon carbide (SiC) waxay u baahan tahay ilo kaarboon saafi ah. Ka dib kaalshiyamaynta, kookaha batroolka ee garaafka lagu sameeyay wuxuu muujiyaa wax yar oo isbeddelaya iyo garaafisinta la xoojiyay, taasoo bixisa ilo kaarboon oo deggan oo kor u qaada falcelinta wejiga adag ee u dhaxaysa silikoon iyo kaarboon si loo soo saaro silikoon carbide saafi ah oo sarreeya.
2. Codsiyada Agabka Baabi'iya
Kookaha batroolka waxaa si toos ah loogu isticmaali karaa in lagu sameeyo walxaha silikoon carbide (tusaale ahaan, giraangiraha shiidi, warqadda ciidda). Adkaanta sare iyo iska caabbinta xirashada ayaa ka dhigaya walxo muhiim u ah farsamaynta birta, nadiifinta dhoobada, iyo codsiyada kale.
3. Hagaajinta Habka
- Daawaynta Calcination: Calcining coke-ka batroolka ceeriin ah heerkulka 1300°C wuxuu yareeyaa heerka haydarojiinta wuxuuna xoojiyaa graphitization-ka, isagoo hagaajinaya socodka korontada iyo iska caabbinta kulaylka ee alaabada silicon carbide.
- Xakamaynta Cabbirka Walxaha: Hagaajinta cabbirka walxaha kookaha batroolka waxay wanaajisaa habka kiristaalka ee silikoon carbide, taasoo kor u qaadaysa isku mid ahaanshaha badeecada.
III. Doorka Dhammaystiran iyo Qiimaha Warshadaha
1. Waxtarka Dhalmada oo La Xoojiyay
Korantada korantada iyo xasilloonida kiimikada ee kookaha batroolka ee graphitized wuxuu yareeyaa isticmaalka tamarta ee foornada korantada, wuxuu gaabinayaa wareegyada dhalaalinta, wuxuuna hagaajiyaa hufnaanta wax soo saarka. Tusaale ahaan, wax soo saarka silikoonka warshadaha, isku darka kookaha batroolka ee saxda ah wuxuu hoos u dhigi karaa isticmaalka korontada 5%-10%.
2. Hubinta Tayada
Xakamaynta heerarka baaruudka, dambaska, iyo wasakhda ku jirta kookaha batroolka waxay yaraynaysaa ku darista aan birta ahayn ee silikoonka warshadaha waxayna kor u qaadaysaa daahirnimada silikoonka carbide, iyadoo buuxinaysa baahiyaha wax soo saarka heerka sare ah (tusaale ahaan, silikoonka carbide-ka heerka semiconductor-ka ah).
3. Horumarinta Casriyeynta Warshadaha
Iyadoo warshadaha wax-soo-saarka ay u socdaan hawlgallo ballaaran oo caqli badan, daahirnimada sare ee kookaha batroolka ee garaafka lagu sameeyay iyo kirismaska ayaa taageera soo saarista koolada elektiroodhka waxqabadka sare leh iyo elektroodhada kaarboonka waaweyn, taasoo kor u qaadaysa casriyeynta tignoolajiyada ee qaybta oo dhan.
