Walxaha kuleyliyaha graphite ee Foornooyinka Vaccum

Walxaha kuleyliyaha garaafka ee Foornooyinka Vaccum Sawirka

Sharaxaad Gaaban:

Qaybaha kuleyliyaha ee Semicera's Graphite Foornooyinka Vacuum waxaa loogu talagalay in lagu bixiyo waxtarka kulaylka sare iyo isku halaynta jawi heerkul sare ah. Laga sameeyay garaafka tayada sare leh, walxahan kuleyliyaha ayaa bixiya qaybinta kulaylka wanaagsan, caabbinta kiimikada, iyo waxqabadka muddada dheer. Ku habboon in loogu isticmaalo foornooyinka faakuumka ee warshadaha sida semiconductors, metallurgy, iyo qalabaynta, walxaha kuleylka ee Semicera's graphite waxay xaqiijiyaan xakamaynta heerkulka saxda ah iyo hufnaanta kuleylka ugu fiican, xitaa xaaladaha ugu baahida badan.

Tilmaamaha ugu muhiimsan ee kuleyliyaha garaafka:

1. isku mid ahaanshaha qaab dhismeedka kuleylka.

2. koronto wanaagsan iyo culeys 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.
