Abstract
Disclosed is a lime milk comprising at least 40 wt. % of dry matter composed of hydrated lime; 0.1 to 3 dry wt. % of carbohydrate dispersants selected from monosaccharides, disaccharides, oligosaccharides, their alkoxide form and derivatives thereof obtained by oxidation or hydrogenation; 0.1 to 3 dry wt. % of a dispersant comprising polycarboxylic polyether copolymers obtained by copolymerization of unsaturated ethylene monomers having between 15 and 100 moles of C2-C3 oxyalkylene groups, and unsaturated ethylene monomers of mono- or dicarboxylic acids, and/or their salts and/or the C1-C4 alkyl esters thereof. In some aspects, the proportion between the dispersant of the carbohydrate type and the dispersant of the copolymer type is between 5:1 and 1:1; the particle size distribution of hydrated lime comprises at least 99% of particles having a size lower than 100 μm; at least 75% of particles having a size greater than 1.2 μm.
