Method for producing cosmetic plaster slurry for use in gypsum board, including gypsum board and non-pregelatinized diffusible starch

摘要

A method for continuously forming a gypsum-based panel, comprising the steps of forming a mixture comprising cosmetic plaster, diffusible starch, glass fiber, and water, and forming the mixture into a band formed without breaks. Maintaining the band under conditions to form a gypsum seam base on which the decorative plaster has set; cutting the band to form one or more wet panel precursors; and Drying the wet panel precursor to form one or more gypsum-based panels, wherein the weight ratio of water to cosmetic plaster in the mixture is less than 0.7, the cosmetic plaster There is an amount exceeding 60% by mass with respect to the total solid content in the mixture, the starch has an amount exceeding 3% by mass with respect to the cosmetic plaster in the mixture, and the glass fiber is in the mixture There is an amount of more than 1% by weight, based on the serial stucco, the density of the gypsum-based panel may be greater than 700 kg / m ^3.
