Gypsum slurries with linear Polycarboxylate Dispersant.

摘要

A Gypsum slurry that includes water, a Hydraulic Component includes Calcium sulfate hemihydrate and linear Polycarboxylate Dispersant.The linear Anionic Polycarboxylate Dispersant includes a First unit and a Second Unit monomÉrica Repetitive monomÉrica Repetitive.The First Unit Repetitive linear Polycarboxylate Dispersant is a Repetitive Unit of carboxÍlico olefÍnico unsaturated acid or a Salt thereof.The Second Unit Repetitive linear Polycarboxylate Dispersant is a Vinyl sulfonate. The slurry can be converted in a Gypsum panel.Also describes methods for producing Gypsum slurry and Plaster Board.
