Birta Silikoon
Gsifooyinka tamarta ee birta silikoon
Birta Silicon waxa kale oo loo yaqaan silikoon bir ah ama, inta badan, si fudud silikoon.Silikoon lafteedu waa curiyaha sideedaad ee ugu badan koonka, laakiin marar dhif ah ayaa laga helaa qaab saafi ah oo dhulka ah.Adeegga Soo-saarka Kiimikada ee US (CAS) ayaa siisay lambarka CAS 7440-21-3.Birta Silikoon ee qaabkeeda saafiga ah waa cawl, dhalaalaysa, curiye metalloidal ah oo aan lahayn ur.Meesha dhalaalkeeda iyo barteeda karkaraya aad bay u sarraysaa.Silikon bir ah ayaa dhalaalaysa qiyaastii 1,410°C.Barta karkarinta ayaa xitaa ka sii sareysa oo waxay gaartaa ilaa 2,355°C.milanka biyaha ee birta silikoon aad bay u hoosaysaa taas oo loo arko inay tahay mid aan milmi karin ficil ahaan.

Xirmada: Waxaa ku jira 1-Ton bacaha xamuulka ah oo dabacsan, sidoo kale waxay bixiyaan xirmo waafaqsan shuruudaha macaamiisha;
Maxaa Birta Silicon loo isticmaalaa?
Birta Silicon waxaa badanaa loo isticmaalaa sidii looga shaqaaleysiin lahaa warshadaha kiimikooyinka ee soo saarista siloxanes iyo silikoon.Birta silikoonka waxa kale oo loo isticmaali karaa sida walxo lagama maarmaanka u ah elaktrooniga iyo warshadaha qoraxda (chips silicon, semi-conductors, solar panels).Waxa kale oo ay hagaajin kartaa sifooyinka horeba waxtarka leh ee aluminiumka sida kasbashada, adkaanta iyo xoogga.Ku darista birta silikoon ee aluminiumyada aluminiumku waxay ka dhigtaa iftiin iyo xoog.Markaa, waxaa si isa soo taraysa loogu isticmaalaa warshadaha baabuurta.Loo isticmaalo in lagu beddelo qaybaha birta ee culus.Qaybaha baabuurta sida baloogyada mishiinada iyo cidhifyada taayirka ayaa ah qaybaha ugu badan ee aluminiumka ah ee silikon shubka ah.
Codsiga birta Silicon waxaa lagu soo koobi karaa sida soo socota:
● aluminium aluminium (tusaale aluminium aluminium aluminium ah oo xoog badan oo loogu talagalay warshadaha baabuurta).
● samaynta siloxanes iyo silicones.
● Waxyaabaha aasaasiga ah ee wax gelinta ee soo saarista qaybaha sawir-qaadista.
● soo saarista silikon heerka elektarooniga ah.
● soo saarista silica amorphous synthetic.
● codsiyada kale ee warshadaha.
