Alumina (Al2O3) Kubadaha shiida
Kubadaha wax lagu shiidi karo alumina ayaa si weyn loogu isticmaalaa miraha kubbadda sida warbaahinta abrasive ee alaabta ceeriinka ah iyo alaabta dhalaalka ah.Warshadaha dhoobada, sibidhka iyo dhaldhalaalka iyo sidoo kale dhirta shaqada dhalada ah ayaa isticmaala iyaga sababtoo ah heerka sare ee cufnaanta sare, adkaantooda sare, iyo caabbinta sare ee xirashada.Inta lagu jiro farsamaynta xoqidda/shiidida, kubbadaha dhoobada ah marar dhif ah ayaa la jebin doonaa oo qodobka wasakhaysan ayaa ah mid aad u yar.
Faa'iidooyinka
1.High wear-resistanceKubadaha wax lagu shiido waxay ka sarreeyaan kubbadaha alumina ee caadiga ah, marka ay shaqaynayso, kubbaddu ma nijaasayn doonto qalabka wax lagu shiido, si ay u ilaaliso nadiifnimada iyo hagaajinta xasiloonida alaabta la shiiday gaar ahaan glaze dhoobada.
2.High DensityThe cufnaanta sare, engegnaanta sare iyo jilayaasha shiidi sare badbaadiyaan waqtiga shiida, ballaadhiyaan qolka jajabinta.Markaa waxay wanaajin kartaa hufnaanta shiididda.
