Faahfaahinta Badeecada

Calaamadaha Alaabta

Tayada sare ayaa ugu horreysa; taageeradu waa tan ugu horreysa; ganacsigu waa iskaashi” waa falsafaddeenna ganacsiga yar yar oo si joogto ah loo ilaaliyo oo ay u raacdo ururkayagu muddo 8 sano ah Dhoofiye Qiimo jaban oo Tayada Sare leh Badeecadaha Tuubada Sic ee Foornada Kuleyliyaha Heerkulka Sare, Iskaashiga daacadda ah oo aad la leedahay, gebi ahaanba wuxuu soo saari doonaa berri farxad leh!
Tayada sare ayaa ugu horreysa; taageeradu waa tan ugu horreysa; ganacsigu waa iskaashi” waa falsafaddeenna ganacsiga yar yar oo si joogto ah loo ilaaliyo oo ay u raacdo ururkeennuKuleyliyaha Shiinaha iyo Kuleyliyaha Heerkulka SareWaxaan si dhab ah u rajeyneynaa inaan xiriir ganacsi oo muddo dheer ah la yeelano shirkaddaada sharafta leh fursaddan, oo ku salaysan ganacsi siman, faa'iido leh iyo guul-guul leh laga bilaabo hadda ilaa mustaqbalka.
Kuleyliyaha garaafka
Qaybaha kululeeyaha garaafka waxaa loo isticmaalaa foornada heerkulka sare leh iyadoo heerkulku gaaray 2200 digrii jawiga faakuumka iyo 3000 digrii jawiga gaaska ee la deoksaydhay oo la geliyay.
Astaamaha ugu muhiimsan ee kululeeyaha graphite:
1. isku mid ahaanshaha qaab-dhismeedka kuleylinta.
2. Korantada oo si fiican loo isticmaalo iyo culays koronto oo sarreeya.
3. iska caabbinta daxalka.
4. oksaydh la'aan.
5. daahirnimo kiimiko oo sareysa.
6. xoog farsamo oo sare leh.
Faa'iidada waa tamar hufan, qiimo sare iyo dayactir hooseeya.
Waxaan soo saari karnaa ka-hortagga oksaydheynta iyo cimri dheer oo graphite crucible ah, caaryada graphite iyo dhammaan qaybaha kuleyliyaha graphite.
Qiyaasaha ugu muhiimsan ee kululeeyaha graphite:

Qeexitaanka Farsamada	VET-M3
Cufnaanta Badan (g/cm3)	≥1.85
Waxyaabaha Dambaska ah (PPM)	≤500
Adkaanta Xeebta	≥45
Iska caabinta Gaarka ah (μ.Ω.m)	≤12
Xoogga Laab-jeexa (Mpa)	≥40
Xoog Cadaadis ah (Mpa)	≥70
Cabbirka ugu Badan ee Badarka (μm)	≤43
Isugeynta Ballaarinta Kulaylka M/°C	≤4.4*10-6

Kuleyliyaha garaafka ee foornada korontada ku shaqeeya wuxuu leeyahay sifooyin iska caabbinta kulaylka, iska caabbinta oksaydhka, gudbinta korantada oo wanaagsan iyo xoojinta farsamada oo wanaagsan. Waxaan mashiin ku samayn karnaa noocyo kala duwan oo kuleyliyaha garaafka ah iyadoo loo eegayo naqshadaha macaamiisha..
