Description

Technical Field

[0001] The utility model belongs to the technical field of plate structure, and in particular relates to a crack-proof full birch board. Background Art

[0002] Multilayer boards are made by hot-pressing three or more layers of veneer or thin boards by gluing them together. After the multilayer boards are made, the shape and material will not change. At this time, the key factors that determine the intrinsic quality of solid wood multilayer boards are its moisture content and drying stress. However, since multilayer boards are made by gluing three or more layers of veneer together, some manufacturers use different wood species for the veneers in the same multilayer board in order to save costs. The moisture content of the veneers varies greatly, making it difficult to achieve a certain balance. Therefore, multilayer boards are prone to reduced strength, warping, cracking and deformation. Therefore, the utility model proposes a multilayer board structure that can prevent the board from warping, cracking, twisting and deformation.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
