Tayada wanaagsani waxay ku bilaabataa; adeegga ayaa ugu horreeya; Ururka waa iskaashiga" waa falsafada ganacsiga our si joogto ah loo arkay oo ay eryan by our shirkad qiimo jaban Shiinaha High Heerkulka Resistance Molybdenum Graphite Crucible Metal dhalaalaysa dheriga, Arkay aaminsan!
Tayada wanaagsani waxay ku bilaabataa; adeegga ayaa ugu horreeya; ururku waa iskaashiga" waa falsafada ganacsiga ee si joogto ah loo ilaaliyo oo ay daba gasho shirkadeenaShiinaha Molybdenum Crucible, Crucibles Iibka, Waxaan bixinaa adeeg khibrad leh, jawaab degdeg ah, gaarsiinta waqtiga, tayada ugu fiican iyo qiimaha ugu fiican macaamiishayada. Ku qanacsanaanta iyo ammaanta wanaagsan ee macmiil kasta waa mudnaantayada. Waxaan diiradda saareynaa faahfaahin kasta oo ku saabsan habaynta macaamiisha ilaa ay ka helayaan badeecooyin ammaan ah oo wanaagsan oo leh adeeg saadka iyo kharash dhaqaale oo wanaagsan. Iyadoo taas ku xiran, baayacmushtarkeena si aad u wanaagsan ayaa loogu iibiyaa wadamada Afrika, Bariga Dhexe iyo Koonfur-bari Aasiya. Anagoo raacayna falsafada ganacsi ee 'macmiilka marka hore, horay u sii wad', waxaanu si kal iyo laab ah u soo dhawaynaynaa macaamiisha ka timid gudaha iyo dibaddaba inay nala shaqeeyaan.
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.
Shirkaddayadu waxay bixisaa adeegyada habka daahan SiC by habka CVD on dusha graphite, ceramics iyo alaabta kale, si gaas gaar ah oo ay ku jiraan kaarboon iyo Silicon falgal heerkulka sare si ay u helaan daahirsanaan sare SiC molecules, molecules kaydin 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 caabinta nabaadguurka: adkaanta sare, dusha sare, qaybo yaryar.
4. Iska caabinta daxalka: acid, alkali, milix iyo reagents organic.
