Iyada oo la adeegsanayo wadarta guud ee habka maaraynta tayada sayniska ee tayada sare leh, tayada sare leh iyo iimaanka aad u fiican, waxaan helnaa magac weyn oo aan ku qabsanay goobtan Shiinaha ee jumlada Shiinaha soo saaraha ee Tayada Sare ee Graphite Crucible / Doon, waxaan si dhakhso ah u xallin karnaa dhibaatooyinka macaamiishayada oo aan faa'iido u helno macmiilka.Kuwa u baahan bixiye heer sare ah oo heer sare ah , pls noo door , mahadsanid !
Isticmaalka guud ahaan habka maaraynta tayada wanaagsan ee sayniska, tayada sare leh iyo iimaanka wanaagsan, waxaan helnaa magac weyn oo aan ku qabsanay goobtanShiinaha Crucible, Graphite Crucible, Waxaan leenahay line wax soo saarka oo dhamaystiran, ururinta line , nidaamka xakamaynta tayada, iyo tan ugu muhiimsan, waxaan leenahay teknoolajiyada patents badan oo khibrad farsamo & kooxda wax soo saarka, kooxda adeegga iibka takhasuska leh.Faa'iidooyinkaas oo dhan, waxaan ku talo jirnay inaan abuurno "summada caalamiga ah ee caanka ah ee naylon monofilaments", oo aan ku faafino alaabadayada gees kasta oo adduunka ah.Waanu sii soconay waxaanan isku daynay intii karaankeena ah si aan ugu adeegno macaamiisheena.
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-da la sameeyay waxay si adag ugu xidhan tahay saldhigga garaafka, iyadoo siinaya saldhigga garaafyada sifooyin gaar ah, sidaas darteed samaynta dusha sare ee garaafka is haysta, 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.
