Alumina Foda/α-Alumina Micropowder
Bayani
Alumina foda wani abu ne na inorganic tare da tsarin sinadaran Al2O3.Yana da wani babban taurin fili mai narkewar 2054°C da wurin tafasar 2980°C.Ionic crystal ne wanda zai iya yin ionize a babban zafin jiki kuma ana amfani dashi sau da yawa wajen kera kayan da ba su da ƙarfi.
Alumina foda shine alumina Al2O3 foda mai ƙarfi, yawanci ana sarrafa shi don α-al2o3 alumina foda, β-al2o3 alumina foda, γ-al2o3 alumina foda azaman amfani daban-daban.
α-Alumina micropowder
α alumina foda yana da matukar kwanciyar hankali na jiki da sinadarai, babban taurin kai, juriya mai ƙarfi, ƙarfin injiniya mai ƙarfi, rufin, juriya mai zafi, ƙarancin ƙonawa, ƙarancin haɓakar haɓakar thermal, kyawawan halayen thermal da sauran halaye.
α alumina yawanci ana amfani da shi azaman abrasive, wakili mai ƙarfi, kayan haɓakawa, kayan goge baki, da sauransu.
Tsarin samarwa
1. Raw material ball niƙa: yana taimakawa wajen kawar da ƙazanta, inganta yawan juzu'i na tsarin harbe-harbe, da kuma ƙara saurin amsawa;
2. Roasting kiln roating: ci gaba da kuma barga samar za a iya gane, kuma za a iya sarrafa gasas zafin jiki daidai;
3. Clinker ball niƙa: Niƙa clinker cikin girman da ake buƙata.
