Title (EN) GYPSUM SLURRIES WITH LINEAR POLYCARBOXYLATE DISPERSANTS
(FR) BOUILLIES DE GYPSE AYANT DES DISPERSANTS DE POLYCARBOXYLATE LINÉAIRE
Abstract: front page image
(EN)A gypsum slurry includes water, a hydraulic component including calcium sulfate hemihydrate and a linear polycarboxylate dispersant. The linear polycarboxylate anionic dispersant includes a first monomeric repeating unit and a second monomeric repeating unit. The first repeating unit of the linear polycarboxylate dispersant is an olefinic unsaturated carboxylic acid repeating unit or salt thereof. The second repeating unit of the linear polycarboxylate dispersant is a vinyl sulfonate. The slurry can be made into a gypsum panel. Methods of making gypsum slurry and a gypsum panel are also disclosed.
(FR)L'invention porte sur une bouillie de gypse qui comprend de l'eau, un composant hydraulique comprenant du hémihydrate de sulfate de calcium et un dispersant de polycarboxylate linéaire. Le dispersant anionique de polycarboxylate linéaire comprend une première unité de répétition monomère et une seconde unité de répétition monomère. La première unité de répétition du dispersant de polycarboxylate linéaire est une unité de répétition acide carboxylique à insaturation oléfinique ou un sel de ce dernier. La seconde unité de répétition du dispersant de polycarboxylate linéaire est un sulfonate de vinyle. La bouillie peut être formée en un panneau de gypse. L'invention porte également sur des procédés de fabrication de bouillie de gypse et sur un panneau de gypse.
