Abstract

Fibres de sulfate de calcium comportant des revêtements minéraux. Ils se caractérisent par le fait que les revêtements sont constitués de composés minéraux très adhérents difficilement solubles, leur proportion par rapport à la fibre enrobée étant comprise entre 0,5 et 10 pour cent en poids. Applications de ces fibres notamment pour le renforcement des produits cellulosiques, des produits synthétiques et des liants minéraux.Calcium sulphate fibers with mineral coatings. They are characterized in that the coatings consist of very adherent, hardly soluble mineral compounds, their proportion relative to the coated fiber being between 0.5 and 10 percent by weight. Applications of these fibers, in particular for the reinforcement of cellulosic products, synthetic products and mineral binders.
