METHOD FOR PRODUCING GYPSUM PLASTERBOARD AND GYPSUM PLASTERBOARD PRODUCED THEREBY Russian patent published in 2019 - IPC C04B28/14 B28B19/00 B28B1/16 B32B13/08 

FIELD: processing of cement, clay and stone.

SUBSTANCE: present invention relates to a gypsum plasterboard containing first outer layer, preferably paper layer (111), first intermediate layer (112) formed by the second gypsum slurry S₂, central layer (113) formed by first gypsum slurry S₁, second intermediate layer (114) formed by third gypsum slurry S₃, and second outer layer, in particular paper layer (115), first intermediate layer (112) is located between first outer layer (111) and core layer (113), and second intermediate layer (114) is located between second outer layer (115) and core layer (113), with intermediate layers (112, 114) having, at least a substantially, constant thickness from 0.1 to 3 mm, preferably from 0.2 to 1 mm, moreover, the first gypsum suspension contains at least 80 % (by weight) of all gypsum suspensions (S₁, S₂, S₃) and moreover, the first gypsum slurry is prepared and injected with a lower percentage of water (by weight) than the second S₂ and / or third S₃ gypsum slurry. Invention also relates to a method for producing the gypsum plasterboard. Invention is developed in dependent paragraphs of the invention claims.

EFFECT: object of the invention to reduce the input of electrical power and carbon dioxide emissions.
