Open publisher page 1 citations

Abstract

In order to prepare the lime milk with high activity and good dispersion,the influence of operating parameters including the slaking temperature,mass ratio of H2O and lime,aging time on the activity of Ca(OH)2 was researched.The slaked lime products were characterized by laser particle analyzer and scanning electronic microscope.The results show that the optimizing conditions are that the slaking temperature is 84 ℃,the mass ratio of H2O and lime is 5∶1 without the need for aging.Under this condition,lime milk can reach a higher activity and have a better dispercenty.
