Waxaan ku raaxaysan xaalad aad u wanaagsan oo ka mid ah rajooyinkayada tayada sare ee badeecadaheena, qiimaha tartanka iyo adeegga ugu habboon ee Supplier Graphite Heater Kuleyliyaha lagu kalsoonaan karo ee lagu dhalaalinayo Shiinaha, Hoggaaminta isbeddelka goobtan waa ujeedkeenna joogtada ah. In aan ku bilowno alaabta fasalka waa ujeedkeena. Si loo abuuro mustaqbal qurux badan, waxaan dooneynaa inaan la shaqeyno dhammaan asxaabta wanaagsan ee gurigaaga iyo dibaddaba. Haddii aad daneyneyso gudaha xalalkayaga, fadlan ma sugi doontid inaad nala soo xiriirto.

Cimri dheer SIC Kuleyliyaha Dahaarka leh ee MOCVD K465i
Qaybaha kuleyliyaha garaafka waxaa loo isticmaalaa foornada heerkul sare oo heerkulku gaaray 2200 darajo deegaanka faakuumka iyo 3000 digrii ee deoxidized iyo deegaanka gaaska la geliyo.
Tilmaamaha ugu muhiimsan ee kuleyliyaha garaafka:
1. isku mid ahaanshaha qaab dhismeedka kuleylka.
2. korantada wanaagsan iyo culays koronto oo sarreeya.
3. iska caabin daxalka.
4. oksidizability.
5. nadiifinta kiimikada sare.
6. xoogga farsamada sare.
Faa'iidada waa tamar hufan, qiimo sare iyo dayactir hooseeya.
Waxaan soo saari karnaa ka-hortagga oksaydhka iyo cimriga dheer ee garaafiga crucible, caaryada garaafka iyo dhammaan qaybaha kuleyliyaha garaafka.
Qiyaasaha ugu muhiimsan ee kuleyliyaha garaafka:
Tilmaamaha Farsamada | VET-M3 |
Cufnaanta Weyn (g/cm3) | ≥1.85 |
Waxyaabaha Ash (PPM) | ≤500 |
Xeebta Adag | ≥45 |
Iska caabin gaar ah (μ.Ω.m) | ≤12 |
Xoog Jilicsan (Mpa) | ≥40 |
Xoog isku dhejisan (Mpa) | ≥70 |
Max. Cabbirka hadhuudhka (μm) | ≤43 |
Isku-dhafka Balaadhinta kulaylka Mm/°C | ≤4.4*10-6 |
Kuleyliyaha garaafka ee foornada korantada wuxuu leeyahay sifooyin caabbinta kulaylka, caabbinta oksaydhka, korantada wanaagsan ee korantada iyo xoojinta farsamada ka wanaagsan. Waxaan mishiin karnaa noocyada kala duwan ee kuleyliyaha graphite sida waafaqsan naqshadaha macaamiisha.
