Method for grinding calcium carbonate in water in the presence of a solution of acrylic polymer and an alkaline carbonate salt manufactured in place in the said solution |
| abstract |
A method for manufacturing an aqueous suspension of calcium carbonate by grinding in an aqueous medium in the presence of an acrylic grinding aid agent and of an alkaline carbonate salt. These salts enable the quantity of grinding aid agent used to be reduced, for an equivalent level of performance in terms of rheology and granulometry of the suspensions. The method includes a first step of manufacture of the alkaline carbonate salt within the aqueous solution of acrylic polymer itself, through the addition of alkaline hydroxide and bubbling of carbon dioxide. |
