Shirkaddayadu waxay ku adkaysanaysaa dhammaan siyaasadda tayada ee "tayada sare ee alaabtu waa saldhigga badbaadada ururka; Raaxada iibsaduhu waxay noqon doontaa barta dheygagga iyo dhammaadka shirkadda; Horumarka joogtada ah waa daba-galka daa'imka ah ee shaqaalaha" oo lagu daray ujeedada joogtada ah ee "sumcada marka hore, iibsadaha ugu horreeya" ee warshadda si toos ah u siisa Shiinaha Electro Graphite Block, Shaqaalaha ganacsigeena oo leh dhammaan isticmaalka teknoolajiyada casriga ah ayaa bixiya xalal aad u fiican oo aad loo jecel yahay. waxaana u mahadceliyey macaamiisheena caalamka.
Shirkaddayadu waxay ku adkaysanaysaa dhammaan siyaasadda tayada ee "tayada sare ee alaabtu waa saldhigga badbaadada ururka; Raaxada iibsaduhu waxay noqon doontaa barta dheygagga iyo dhammaadka shirkadda; Horumarka joogtada ahi waa daba-galka daa'imka ah ee shaqaalahaKaarboon Block, Shiinaha Graphite Block, Shaqaalaheennu waxay u hoggaansamaan ruuxa "Horumarka ku salaysan hufnaanta iyo is-dhexgalka", iyo mabda'a "Tayada heerka koowaad ee leh adeeg heer sare ah". Marka loo eego baahiyaha macaamiil kasta, waxaanu bixinaa adeegyo la habeeyey & kuwo la gaaryeelay si aan uga caawino macaamiisha inay gaadhaan hadafkooda si guul leh. Ku soo dhawoow macaamiisha guriga iyo dibadda si ay u wacaan oo wax u weydiiyaan!
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 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.
