Abstract

The invention discloses a reinforced gypsum board as well as a production system and a production method thereof. The reinforced gypsum board comprises upper surface protection paper, lower surface protection paper and at least two fiber layers arranged between the upper surface protection paper and the lower surface protection paper; every two adjacent fiber layers are connected through vertical yarns to form a three-dimensional fiber structure; and the three-dimensional fiber structure is filled with a plate core.

Description

technical field [0001] This application relates to but not limited to the field of gypsum board production, especially a reinforced gypsum board and its production system and production method. Background technique [0002] Gypsum boards are used in a wide range of applications, and in some special occasions, the strength requirements for gypsum boards are very high. Currently, there are several ways to enhance the strength of gypsum board: first, strengthen the strength of the core, such as increasing the thickness of the core and reducing the cell volume of the core; second, adding additives such as adhesives; Fibrous substances are mixed into the gypsum slurry. However, the strength enhancement degree of the gypsum board by the above methods is limited, and cannot well meet the high-strength requirements of the gypsum board. Contents of the invention [0003] The embodiment of the present application provides a reinforced gypsum board and its production system and pro...
