Helitaanka buuxinta iibsadaha waa ujeedada shirkadeena aan dhamaadka lahayn. Waxaan samayn doonaa dadaallo aad u fiican si aan u helno xalal cusub oo tayo sare leh, la kulanno tafaasiishaada gaarka ah oo aan ku siino iibka hore, iibinta iyo bixiyeyaasha iibka ka dib ee Alaabada Cusub ee Kulul ee Plasma Kordhinta CVD Tube Foornada loogu talagalay Dhigista Sare- Filimada Adag ee Tayada leh, Ku soo dhawoow weydiintaada, adeegga ugu wanaagsan ayaa lagu siin doonaa qalbi buuxa.
Helitaanka buuxinta iibsadaha waa ujeedada shirkadeena aan dhamaadka lahayn. Waxaan samayn doonaa dadaallo aad u fiican si aan u helno xalal cusub oo tayo sare leh, oo aan la kulano tafaasiishaada gaarka ah oo aan ku siin doono iibka kahor, iibka iyo bixiyeyaasha iibka kadibChina CVD Tube Foornada iyo CVD Tube Foornada Foornada Kiimikada Dhigista Uumiga Kiimikada, Suuqa sii kordheysa ee tartanka, Adeeg daacad ah oo tayo sare leh iyo sumcad wanaagsan, waxaan had iyo jeer siinaa macaamiisha taageerada alaabta iyo farsamooyinka si loo gaaro iskaashi muddo dheer ah. Ku-noolaanshaha tayada, horumarka credit-ku waa raadintayada weligeed ah, Waxaan si adag u aaminsanahay in booqashadaada ka dib aan noqon doono lammaane mustaqbalka fog ah.
Kaarboon / kaarboon isku-dar ah(ka dib loo tixraaco "C/C ama CFC”) waa nooc ka mid ah walxaha isku dhafan kaas oo ku salaysan kaarboon oo lagu xoojiyay fiber carbon iyo alaabteeda (kaarboon fiber preform). Waxay leedahay labadaba firfircoonida kaarboonka iyo xoogga sare ee fiber carbon. Waxay leedahay sifooyin farsamo oo wanaagsan, caabbinta kulaylka, iska caabinta daxalka, qoyaanka xoqida iyo sifooyinka kulaylka iyo korantada
CVD-SiCdaahan wuxuu leeyahay sifooyinka qaab-dhismeedka lebis, wax is haysta, iska caabin heerkulka sare, iska caabin oksaydhka, daahirsanaan sare, caabbinta acid & alkali iyo reagent organic, leh guryaha deggan iyo kiimikaad.
Marka la barbar dhigo qalabka garaafyada sare ee nadiifka ah, graphite wuxuu bilaabaa inuu oxidize at 400C, taas oo keeni doonta luminta budada sababtoo ah oksaydheynta, taasoo keentay wasakhowga deegaanka ee aaladaha durugsan iyo qolalka faakuumka, iyo kordhinta wasakhda deegaanka saafiga ah.
Si kastaba ha noqotee, daahan SiC wuxuu ilaalin karaa xasilloonida jirka iyo kiimikaad ee 1600 darajo, Waxaa si weyn loogu isticmaalaa warshadaha casriga ah, gaar ahaan warshadaha semiconductor.
Shirkadeena waxay bixisaa adeegyada habka daahan SiC ee habka CVD ee dusha sare ee graphite, ceramics iyo alaabta kale, si gaasaska gaarka ah ee ay ku jiraan kaarboon iyo silikoon ay uga falceliyaan heerkulka sare si ay u helaan nadiifnimada sare ee SiC molecules, molecules deposited on the dusha alaabta dahaarka ah, samaynta lakabka ilaalinta SIC. SIC-ga la sameeyay waxay si adag ugu xidhan tahay saldhigga garaafka, iyadoo siinaya saldhigga garaafyada sifooyin gaar ah, sidaas darteed samaynta dusha sare ee garaafka, Porosity-free, caabbinta heerkulka sare, caabbinta daxalka iyo caabbinta oksaydhka.
Tilmaamaha ugu muhiimsan:
1. Iska caabbinta oksaydhka heerkulka sare:
caabbinta oksaydhisku weli aad bay u wanaagsan tahay marka heerkulku uu gaadho 1600 C.
2. Nadiifin sare: oo ay samaysay uumiga kiimikaad ee hoos yimaada xaalada koloriinaynta heerkulka sare.
3. Iska caabbinta nabaadguurka: adkaanta sare, dusha sare, qaybo yaryar.
4. Iska caabinta daxalka: acid, alkali, milix iyo reagents organic.
