FIELD: construction.SUBSTANCE: invention relates to the production of gypsum board plate (plates dry plaster), use of foamed starch pellets in the production of lightweight gypsum board. Technical result is an improvement of a strength and a lightness of the gypsum board plate. In accordance with the present disclosure, the starch necessary for board formation is provided in the form of starch pellets. These pellets are mixed with a gypsum slurry in a mixer. Pellets are initially insoluble and do not dissolve. However, during subsequent drying stages, the pellets become soluble and dissolve into the gypsum phase.EFFECT: this both provides the desired starch component and also results in the formation of voids within the set gypsum.24 cl, 5 dwg |
