Title (EN) MIGRATING STARCH WITH HIGH COLD-WATER SOLUBILITY FOR USE IN PREPARING GYPSUM BOARD
(FR) MIGRATION D'AMIDON DOTÉ D'UNE SOLUBILITÉ ÉLEVÉE DANS L'EAU FROIDE POUR UNE UTILISATION DANS LA PRÉPARATION DE PLAQUE DE PLÂTRE
Abstract:
(EN) Disclosed is gypsum board formed from stucco, water, and at least one migrating starch having a cold-water solubility of at least about 25%. Generally, the starch has a viscosity of less than about 20 centipoise (e.g., from about 1 centipoise to about 20 centipoise), as determined according to the VMA method. Also disclosed are related slurries and methods of preparing gypsum board.
(FR) L'invention concerne une plaque de plâtre formée à partir de stuc, d'eau et d'au moins un amidon migrant doté d'une solubilité dans l'eau froide d'au moins environ 25 %. Généralement, l'amidon présente une viscosité inférieure à environ 20 centipoises (par exemple d'environ 1 centipoise à environ 20 centipoises), telle que déterminée selon le procédé VMA. La présente invention concerne également des suspensions associées et des procédés associés de préparation de plaque de plâtre.
