Soo saaraha Qiimaha Wanaagsan Calcium Alumina Sibidhka CAS: 65997-16-2
CalciumAlumina Cement waa sibidh leh kalsiyum kalsiyum ama aluminium kalsiyum oo ah qaybteeda ugu weyn ee macdanta.Waxay ka samaysan tahay aluminium dabiici ah ama aluminium warshadeed iyo calcium carbonate (limestone) iyadoo loo eegayo qayb gaar ah, taas oo lagu sameeyo gubasho ama dhalaalid koronto.
Waxyaabaha ay ka kooban yihiin iyo qaybaha: CalciumAlumina Cement waxa loo qaybin karaa sibidhka calcium calcium ee caadiga ah (al2O3 53-72%, CAO 21-35%) iyo sibidh aluminium saafi ah (al2O3 72-82%, CAO 19-23%) Laba qaybood.Sibidhka aluminium ee caadiga ah waxaa loo qaybin karaa nooca birta-hooseeya (FE2O3 <2%) iyo nooca xadiidka xawaaraha sare (Fe2O37-16%).Low-tareen-nooca aluminium-nooca kalsiyum sibidhka waxa loo qaybin karaa sibidhka carrada alum (Al2O353 ~ 56 %, CAO 33-35%), aluminium -60 cement (al2O359% to 61%, CAO 27-31%), iyo hoose -kalcium aluminium asiidh cement (Al2O3 65-70%, CAO 21 ilaa 24%).Sibidhka aluminiumka saafiga ah waxaa loo qaybin karaa laba nooc: Al2O3 72-78%) iyo nooca aluminium ultra-high (Al2O3 78-85%).Intaa waxaa dheer, waxaa jira sibidh kalsiyum aluminium ah oo degdeg ah oo adag.CAS: 65997-16-2
