Título (EN) A PIGMENT PARTICLE COMPOSITION, ITS METHOD OF MANUFACTURE AND ITS USE
(FR) COMPOSITION DE PARTICULES DE PIGMENT, SON PROCÉDÉ DE FABRICATION ET SON UTILISATION
Resumo: front page image
(EN)A pigment particle composition which comprises calcium carbonate particles and pigment particles, its method of manufacture and its use. According to the present invention, the calcium carbonate particles are carbonated so that they bind to each other, in which case calcium carbonate structures are generated, which comprise pigment particles and which form essentially opaque and stable pigment-calcium carbonate aggregates. It is possible to manufacture the composition by atomizing calcium hydroxide-bearing pigment slurry into a carbon dioxide-bearing gas, in which case the calcium hydroxide is carbonated in order to precipitate the calcium hydroxide particles to be attached to each other and the carbonation is continued until essentially all of the calcium hydroxide has been converted into calcium carbonate. The composition is suitable for use, among others, in paints, coating materials, fillers, polymers and printing inks.
(FR)La présente invention concerne une composition de particules de pigment qui comprend des particules de carbonate de calcium et des particules de pigment, son procédé de fabrication et son utilisation. Selon la présente invention, les particules de carbonate de calcium sont carbonatées de sorte qu’elles se lient les unes aux autres, auquel cas des structures de carbonate de calcium sont générées, qui comprennent des particules de pigment et qui forment des agrégats pigment-carbonate de calcium pratiquement opaques et stables. Il est possible de fabriquer la composition en atomisant une suspension de pigment comportant de l’hydroxyde de calcium dans un gaz comportant du dioxyde de carbone, auquel cas l’hydroxyde de calcium est carbonaté afin de précipiter les particules d’hydroxyde de calcium de manière à être liées les unes aux autres et la carbonation est prolongée jusqu’à ce que pratiquement tout l’hydroxyde de calcium ait été converti en carbonate de calcium. La composition est adaptée pour utilisation, entre autres, dans des peintures, des matériaux de revêtement, des charges, des polymères et des encres d’impression.
