The uses of an agent of CO grinding and aqueous suspensions and dry pigments of GCC and PCC co crushed and aqueous suspensions and dry pigments of GCC and PCC co crushed
The uses of an agent of CO grinding and aqueous suspensions and dry pigments of GCC and PCC co crushed and aqueous suspensions and dry pigments of GCC and PCC co crushed the invention consists in the use, in a manufacturing process of GCC and PCC co crushed into w A,An agent of CO grinding is characterized by the fact that: (a) it is constituted of at least one homopolymer and / or of a copolymer of acrylic acid partially neutralized, whose rate of neutralization molar is less than 75% of the total amount of the acid functions, (b) and that he is a Introduced: during the preparation step of aqueous suspensions of GCC and PCC.And / or during the step of CO grinding, and possibly between the step of CO grinding and another step of concentration and possibly during this stage of concentration. The invention also resides in aqueous suspensions of GCC and PCC and GCC and PCC pigments dry results Ined, and the use of these products in paper, paint, rubber and plastic.
