Use of alkaline carbonate salts to reduce the amount of acrylic polymer in a method for grinding calcium carbonate in water |
| abstract |
The invention relates to the use of alkaline carbonate salts in a method for producing an aqueous suspension of calcium carbonate by grinding. Said salts make it possible to reduce the amount of agents for assisting in grinding used, said agents being homopolymers or water-soluble acrylic acid copolymers. The latter contribute greatly to increasing the concentration of carbon dioxide in the atmosphere and are produced from fossil-fuel raw materials; limiting the amount thereof helps save the environment as well as our natural resources. Said alkaline carbonate salts are directly used by being mixed with the polyacrylate (i.e. prior to the grinding operation) and/or are added during grinding, at the same time as the polyacrylate. |
