| titleOfInvention | Method of manufacturing aqueous calcium carbonate suspensions and suspensions obtained as well as their uses |
| abstract | Manufacturing method of an aqueous suspension of natural calcium carbonate characterized in that it comprises the following steps: a) dry and/or wet pre-milling of calcium carbonate to an average diameter of 0.5 to 500 μm (d50) in the presence or in the absence of dispersing agents, b) form an aqueous suspension of the product of step a) by adding the necessary amount of water to obtain a dry calcium carbonate content of between 10% and 80%, preferably between 30% and 50% and very preferably between 35% and 45%, c) grinding the suspension resulting from step b) in the presence of a (meth)acrylic acid homopolymer and/or copolymer having at the same time a molecular weight between 8000 g /mol and 15,000 g/mol, preferably between 10,000 g/mol and 14,000 g/mol, most preferably in the order of 12,000 g/mol and a molar content of polymer chains with a molecular weight of less than 3,000 g/mol to less than 20 %, preferably 15%, most preferably 10%, d) optionally concentrated Treat the aqueous suspension obtained in step c) by any known means in order to obtain a calcium carbonate content of at least 5% in the concentration of step b) or c), which preferably comprises between 60% and 80%. by weight, and most preferably between 65% and 75% by weight, e) optionally adding a dispersing agent to the aqueous suspension during or after step d). |
