SOLUTION CONTAINING ACID-MODIFIED DRY MIXTURE, GYPSUM PANEL MADE FROM THIS SOLUTION, AND METHOD OF PRODUCING SAID GYPSUM PANEL Russian patent published in 2025 - IPC C04B28/14 E04C2/04 

FIELD: chemistry.

SUBSTANCE: invention contains a solution containing an acid-modified dry mixture, a gypsum panel made from this solution, and a method of producing said gypsum panel. Method of making gypsum board includes: forming acid-modified dry mixture; adding an acid-modified dry mixture to water and plaster to form a solution; placing the gypsum board core forming solution between the first and second cover sheet to form a wet assembly; cutting the wet assembly into gypsum panels; drying the gypsum panel. Acid-modified dry mixture is formed by combining the initial dry mixture after the dry grinding process, heating the mixture and adding a neutralizer to the mixture, additionally drying and removing agglomerates. Plaster solution used in making the gypsum panel contains water, plaster and an acid-modified dry mixture.

EFFECT: improved technological process by reducing production operations.
