Silicon Carbide (SiC) Dulmarka budada
Silicon carbide (SiC), oo sidoo kale loo yaqaan carborundum ama emery, waa mid ka mid ah agabka aadka loo isticmaalo iyo dhaqaalaha. SiC waxaa lagu heli karaa laba qaab: carbide silicon madow iyo carbide silicon cagaaran.
Habka wax soo saarka
SiC waxa soo saara dhalaalaysa ciid quartz, kookaha batroolka, ama daamurka dhuxusha, iyo jajabyada alwaax ee heerkul sare ee foornada iska caabinta. Carbide silikoon cagaaran ayaa si gaar ah loo sameeyay iyadoo dhalaalaysa silikoon dioxide iyo kookaha batroolka oo tayo sare leh, iyadoo cusbo lagu daray wax lagu daro.
Guryaha iyo Codsiyada
- Adag:Ku dhaca inta u dhaxaysa corundum iyo dheeman.
-Awoodda Makaanikada:Ka sarreeya korundum, jajaban, iyo fiiqan.
-Akhlaaqda:Leh koronto iyo kulaylka qaarkood.
Sababo la xiriira guryahan, SiC waxay ku habboon tahay codsiyada u baahan adkeysiga iyo maaraynta kulaylka. Waxaa si weyn loogu isticmaalaa warshadaha sida abrasives, refractories, iyo semiconductors.
Sifooyinka Silicon Carbide
1. Balaadhinta kulaylka hoose:Waxay yaraynaysaa isbeddellada cabbirka iyadoo leh isbeddellada heerkulka.
2. Dhaqdhaqaaqa Heerarka Sare:Si hufan u gudbiya kulaylka.
3. Cadaadiska Cadaadiska Kulaylka:Waxay yaraynaysaa suurtogalnimada diiqada kulaylka.
4. Iska caabinta shoogga kulaylka heer sare ah:U adkaysta isbeddelada heerkulka degdega ah.
5. Iska caabinta daxalka:Waarta ka-hortagga waxyeelada kiimikada.
6. Dulqaadka heerkulka aad u daran: Si fiican ayey ugu shaqeysaa jawi aad u qabow iyo mid kulul labadaba.
7. Iska caabinta gurguurta Heerkulka Sare:Waxay ilaalisaa xasilloonida iyo xoogga heerkulka sare.
Semicera waxay u habeyn kartaa 4N-6N silicon carbide budada si waafaqsan baahidaada, ku soo dhawoow inaad wax weydiiso.
