TheDaboolka CVD SiCUsha isku dhafan ee CC,Usha Kaarboon-Kaarbon Kaarboon-Kaarboon Isku-dhafka ah, SiC Coated CC Composite Rod oo ka socda vet-china wuxuu isku daraa sifooyinka gaarka ah eeKaarboon-carbon (CC) oo isku dhafanoo leh difaacCVD SiC (Silicon Carbide) daahan. Ushaan horumarsan waxaa loogu talagalay codsiyada waxqabadka sare leh ee u baahan xasilloonida kulaylka sare, xoogga farsamada, iyo iska caabinta kiimikada. Xudunta kaarboon-carbon waxay bixisaa adkeysi aad u wanaagsan iyo sifooyin fudud, halka dahaarka SiC uu kor u qaado iska caabinta xirashada, oksaydhka, iyo heerkulka sare.
Dahaarka CVD SiC wuxuu bixiyaa ilaalin adag, taasoo u oggolaanaysa usha inay u adkeysato xaaladaha ba'an, taasoo ka dhigaysa mid ku habboon wax soo saarka semiconductor, hawada hawada, iyo hababka warshadaha. vet-china waxay hubisaa inDaboolka CVD SiCUsha isku dhafan ee CC waxay xamili kartaa heerkulka ka sarreeya 1600°C, taasoo bixisa isku halaynta deegaan u baahan saxnaanta iyo cimriga labadaba.
Usha isku-dhafka ah ee vet-china waxaa loo naqshadeeyay inay ku shaqeyso xaaladaha ugu adag, hubinta xasilloonida iyo kordhinta cimriga qaybaha warshadaha baahida sare leh. Isku darka dahaadhka CVD SiC iyo qaab dhismeedka isku dhafan ee CC ayaa keenaya badeecad aan miisaankeedu fududayn oo keliya balse si gaar ah u xoog badan oo u adkaysata xidhashada iyo jeexjeexa.
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.
