Sizing dispersions of liquid reactive size are made by dispersing the reactive size as a neat liquid into a dispersion of bentonite or other anionic microparticulate material in water. These dispersions can be used for internal sizing, for instance wherein the dispersion is used as the anionic microparticulare stage in a microparticulate retention paper-making process, or they can be used for external sizing.
Des dispersions de colle réactive liquide sont fabriquées en dispersant la colle réactive, sous forme liquide, pour la transformer en dispersion de bentonite ou d'un autre matériau microparticulaire anionique dans l'eau. Ces dispersions peuvent être utilisées pour le collage interne, par exemple, lorsque la dispersion est utilisée comme étape de matière microparticulaire anionique au cours d'un procédé de fabrication du papier à rétention de matière microparticulaire, ou elles peuvent servir pour le collage externe.
