Raadintayada iyo ujeeddada shirkadu waa inta badan inay " had iyo jeer buuxiso shuruudaha iibsadaha " Waxaan sii wadnaa inaan soo saarno oo aan u habeyno wax soo saar tayo sare leh oo loogu talagalay macaamiisheena hore iyo kuwa cusub labadaba waxaanan xaqiijineynaa rajada guuleysiga ee macaamiisheena sidoo kale annagoo ah soo saaraha Shiinaha Carbon Graphite Mold Loo isticmaalo polishing la taaban karo, Helitaanka joogtada ah ee badeecadaha heerka sare ah marka lagu daro taageeradayada wanaagsan ee ka hor iyo ka dib iibka waxay hubisaa tartan xoogan suuqa caalamiga ah ee sii kordheysa.
Raadintayada iyo ujeeddada shirkadu waa inta badan inay " had iyo jeer buuxiso shuruudaha iibsadaha " Waxaan sii wadnaa inaan soo saarno oo aan u habeyno alaab tayo sare leh oo loogu talagalay macaamiisheena hore iyo kuwa cusub labadaba waxaanan xaqiijineynaa rajo-guulnimo macaamiishayada sidoo kale annaguChina Carbon Graphite Molds, Qaababka garaafka, Magaca Shirkadda, had iyo jeer waa la xiriira tayada sida aasaaska shirkadda, raadinta horumarinta via heerka sare ee kalsoonida , u hoggaansamaan heerka maamulka tayada ISO si adag, abuurista shirkadda sare-sare by ruuxa horumar-calaamad daacadnimo iyo yididiilo.
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.
