摘要:
The object of the invention consists of a process for the manufacture of aqueous suspensions of calcium carbonate using an acrylic polymer with an average by weight molecular weight of between 8,000 g/mole and 15,000 g/mole and a molar content of less than 20% of polymeric chains of molecular weight less than 3,000 g/mole. It also concerns the aqueous suspensions obtained, possibly dried, and their uses in the paper, paint, plastics and mastics industry.
摘要:
The invention concerns a new synthetic mineral matter containing carbonate, the decomposition of which reduces the rate of fossil fuel carbon dioxide emission. It also concerns its manufacture in batches, or in a batch-continuous manner, or in a continuous manner, together with its uses in the pharmaceutical field, the field of human or animal foodstuffs, or again the papermaking field with, notably, manufacture of paper, filler or coating, or again every other paper surface treatment, together with the fields of water-based or non-water-based paints, together with the field of plastics, such as that of breathable polyethylene films, or again the field of printing inks.
摘要:
Composite compounds of co-structured or co-adsorbed organic or mineral fillers or pigments containing at least two organic or mineral fillers or pigments of a different nature and the use thereof in the paper industry for manufacturing paper, filling or coating or for any other surface treatment of the paper as well as wood or metal or plastic or cement surface treatment compounds in the fields of aqueous and non-aqueous paints and plastics materials.Coatings colors, uncoated filling compound and sheets of base paper for coating containing them.

摘要:
The invention relates to the use of a weakly ionic and water-soluble copolymer as a grinding aid agent for grinding mineral matter in aqueous suspension in order to obtain aqueous suspensions of refined mineral matter, with a dry matter concentration that can be high, with a low Brookfield™ viscosity that remains stable over time, having the property that it presents a pigmentary surface area the ionic charge of which, as determined by ionic titration, is low.The invention relates to the aqueous suspensions of mineral matter obtained and their use in the fields of paper, paint and plastics.
摘要:
The invention concerns a process for manufacturing a dry mineral pigment containing a product formed in situ by the multiple reaction between a calcium carbonate and the product or products of reaction of the said carbonate with one or more moderately strong to strong H30+ ion donators and the product or products of reaction of the said carbonate with gaseous CO2 formed in situ and/or originating from an external supply and one or more compounds of formula R—X together with the mineral pigment obtained by the process, and its applications in the field of paint and/or plastics.
摘要:
The present invention relates to the technical mineral matter suspension sector, and, before and/or after drying, their applications in the fields of paper, paint and, after drying, plastics. It also relates to the use of a copolymer having at least one alkoxy or hydroxy polyalkylene glycol function grafted onto at least one ethylenically unsaturated monomer, as agent whose role is to enhance the gloss of the final product and, in particular, the gloss of the sheet of paper, irrespective of the viewing angle.
