摘要： A gypsum slurry is provided that includes calcium sulfate hemihydrate; water; a dispersant component comprising at least one of the following a comb-branched polymer with polyether side chains, naphthalene sulfonate-formaldehyde condensate or melamine sulfonate-formaldehyde condensate; a foaming agent; and a polycondensation component with three polycondensation repeating units. Also provided is a method for making a gypsum slurry with a foaming agent in which the ratio between the dispersant component and the polycondensation component is adjusted to control for the size of foam bubbles in the gypsum slurry. Gypsum products made from the gypsum slurry are provided and methods for making the products are provided as well.
