Abstract
Description
technical field
[0001] The invention relates to the technical field of boards, in particular to blockboards. Background technique
[0002] Blockboard, commonly known as large core board, is made of two veneers glued together in the middle. The total thickness of the double-sided glued veneers of the blockboard shall not be less than 3mm. The corner defects of various blockboards shall not exceed 5mm in width and 20mm in length within the nominal format. The middle plank is made of high-quality natural planks after heat treatment (that is, drying in the drying room), and then processed into wooden strips of certain specifications, which are spliced by a jigsaw machine. The spliced wooden boards are covered with two layers of high-quality veneer on both sides, and then glued by cold and hot presses. Since blockboard is a special plywood, the principle of symmetry should also be followed in the production process to avoid warping and deformation of the board. As a thick ...

Embodiment Construction
[0012] A blockboard is a composite wood board that is vertically symmetrical with a core 1 as the center, and is composed of a core 1, a bamboo charcoal layer 2, a PVC layer 3, an imidazoline layer 4, and an adhesive veneer 5. The board core 1 is formed by interlocking and splicing diamond-shaped planks, and two layers of bamboo charcoal layers 2 are arranged on the left and right sides of the board core 1 respectively, and the thickness of the bamboo charcoal layer 2 is between 0.4-0.6 mm. A PVC layer 3 is arranged between two layers of bamboo charcoal layers 2, and a layer of bamboo charcoal layer 2 is arranged, and finally an imidazoline layer 4 and an adhesive veneer 5 are arranged in sequence. The thickness of the imidazoline layer 4 is between 0.5-1 mm. Add at least one of polyvinyl alcohol, polyethylene glycol, and hydroxymethyl cellulose to the glue for gluing the veneer 5 .
