Qaybaha Garaafka Saxda ah ee Injineerka ee Semicera ee Baahiyaha Warshada ee La Habeeyay

Sharaxaad Gaaban:

Garaafkayaga istatic-ka ee cufnaanta sare leh, oo ay soo saartay Semicera, ayaa ku habboon codsiyo badan oo cadaadis sarreeya. Garaafyadan gaarka ah ayaa si taxadar leh loo sameeyay iyadoo la adeegsanayo tignoolajiyada horumarsan si loo hubiyo cufnaanta sare, xoogga, iyo waxqabadka. Iyada oo kuleylkeedu aad u fiican yahay iyo xasillooni, blocksyada garaafyada isostatic waxay bixiyaan isku halleyn gaar ah iyo adkeysiga jawiga baahida. Ku kalsoonow Semicera alaabada garaafyada isostatic ee tayada sare leh ee buuxiya shuruudaha adag ee warshado kala duwan.

Alaabooyinka ugu muhiimsan ee semicera waa graphite qurub qurux badan oo la riixay oo loo isticmaalo semiconductors. Macluumaadka aasaasiga ah ee adduunka ugu horumarsan ee Jarmalka SGL iyo Japan Toyo kaarboon waa sida soo socota:

Halbeegga waxqabadka	semicera	SGL R6510	TOYO IG310
Cufnaanta weyn (g/cm3)	1.91	1.83	1.85
Xoog laabashada (MPa)	63	60	49
Awood cadaadis (MPa)	135	130	103
Hardness Shore (HS)	70	64	60
Dhaqdhaqaaqa kulaylka(W/m·K)	85	105	130
Isku-dhafka ballaarinta kulaylka(10-6/K)	5.85	4.2	5.0
iska caabinμΩm)	11-13	13	10

Faa'iidada waxqabadka:
1.Qabdhismeedku wuu fiican yahay oo cufan, isku-duubnina waa wanaagsan yahay.
2.Low coefficient of ballaarinta kulaylka, caabbinta shoogga kulaylka aad u fiican;
3.Isotropy;
4.Cabsiga kiimikada xooggan;
5.kuleylka wanaagsan iyo korantada;
6.Waxay leedahay sifooyin machining heer sare ah.
