Shaagagga shiidida dhoobada ee SG
SG abrasive waa alumina aluminium polycrystalline abrasive leh qaab-dhismeedka crystalline submicron.Waxay ku siinaysaa wax qabad sare oo ka sarreeya alumina abrasives-ka caadiga ah, sababtoo ah cidhifkeeda goynta si microscopically ah ayaa u jajaban oo awoodda goynta sare waxaa lagu hayaa dusha sare iyo shiidida cylindrical.Shiidashada giraangiraha ka samaysan abrasive dhoobada leh waxay leedahay cimri dheer iyo cimri dheer, taas oo ah 5-10 jeer marka loo eego giraangiraha shiida ee ka samaysan corundum caadiga ah. Its wax-qabad sare leh oo abuur ah jel dhoobada alumina iyo aluminium aluminium friable abrasive isku darka ah waxay qaadataa saddex ilaa shan jeer ka dheer marka loo eego giraangiraha aluminium oksaydh ee caadiga ah, iyo xoqiddeeda is-afaysa waxay kordhisaa cidhifyada fiiqan ee aaladaha wayna dhintaa.
