摘要： The invention relates to the use, in a method comprising a first step of grinding into a calcium carbonate aqueous medium, of an acrylic polymer having a molecular weight between 8,000 g/mol and 15,000 g/mol and a mole content less than 20% in polymer chains having a molecular weight less than 3,000 g/mol. Said method, comprising a second step that is a concentration step, leads to an aqueous suspension with an increased slope factor, which improves the opacity of the coated paper obtained from said suspension.

摘要： The invention relates to the use, in a hydraulic binder-based composition, of a calcium carbonate characterized in that it is obtained by dry-grinding, and in that it is dry-ground in the presence of a grinding aid agent that is a (meth)acrylic acid copolymer with a monomer carrying an alkoxy or hydroxy polyalkylene glycol function. The invention also concerns the hydraulic binder-based compositions thus obtained.

摘要： A first objective of the present invention is a method for dry milling material which contains carbonate ore, characterized in that the said method comprises the following steps: a) dry milling of the said material in at least one milling unit: (i) in the presence of at least one polyalkylene glycol polymer where at least 90% but preferably 95% at least, and very preferably 98% at least of the monomer units forming the backbone of the said polymer are constituted by ethylene oxide, propylene oxide or their mixtures, and where the molecular weight is at least equal to 400 g/mole, (ii) such that the quantity of water in the said milling unit is less than 10% in dry weight of the said material in the said milling unit; b) the milled material may then be classified according to step a) with at least one classification unit; c) the steps a) and/or b) may be repeated with all or part of the milled material from step a) and/or step b). Another aim of the present invention is a product coming from step a) and/or b) and/or c) of the method of the invention. A third object of the present invention is the use of the said product from step a) and/or b) and/or c) for making sealant, paper, paint, plastic or else for formula used in agriculture.
