| abstract |
process of grinding calcium carbonate in water in the presence of an acrylic polymer solution and an alkaline carbonate salt fabricated in situ in said solution the invention relates to a process for manufacturing an aqueous calcium carbonate suspension by grinding in aqueous medium, in the presence of an acrylic crushing aid and alkaline carbonate salts. These salts reduce the amounts of grinding aid employed to an equivalent level of performance in rheology material and suspension particle size. One of the originalities of this method is based on a first step of manufacturing the alkaline carbonate salt within the aqueous acrylic polymer solution itself, by adding alkaline hydroxide and carbon dioxide bubbling. |
