Problems solved by technology

However, even if the bonding surface between the finger-joint strips is changed to an inclined plane, after the finger-joint board is made, the stability of the entire finger-joint board is still not good enough, the joints are not tight, and the glue shrinks easily after hot pressing. There are depressions at the seams, these problems seriously restrict the application of finger joint boards in end products

Embodiment 1

[0030] Embodiment 1, a kind of manufacturing method of large format carbonized plate, comprises the following steps:

[0031] A. Raw materials: Saw poplar fast-growing wood into small fast-growing wood materials of required specifications, adjust the moisture content of small fast-growing wood materials to 8-12%, and the moisture content deviation between small fast-growing wood materials does not exceed 2%. ;

[0032] B. Tenoning; making tenons and tongues on two opposite sides in the length direction and two opposite sides in the width direction of the fast-growing wood small material, and applying glue;

[0033] C. Assemble the length and width; first, the glued fast-growing small pieces are lengthened in the length direction, and then widened in the width direction of the fast-growing small pieces to make a slab;

[0034] D. Sanding and edge trimming of the blank board; sanding and fine sanding the blank board on both sides to the required flatness, and cutting the four s...

Embodiment 2

[0046] Embodiment 2, a kind of manufacturing method of large format carbonized board, comprises the following steps:

[0047] A. Raw material preparation; saw the fast-growing wood into small pieces of fast-growing wood of the required specifications, adjust the moisture content of the small pieces of fast-growing wood to 8%, and the deviation of moisture content between small pieces of fast-growing wood is 1%. ;

[0048] B. Tenoning; making tenons and tongues on two opposite sides in the length direction and two opposite sides in the width direction of the fast-growing wood small material, and applying glue;

[0049] C. Assemble the length and width; first, the glued fast-growing small pieces are lengthened in the length direction, and then widened in the width direction of the fast-growing small pieces to make a slab;

[0050] D. Sanding and edge trimming of the blank board; sanding and fine sanding the blank board on both sides to the required flatness, and cutting the fou...

Abstract

The invention discloses a manufacturing method of a wide-breadth carbonized board, which comprises the following steps: A. material preparing; B. tenoning; C. lengthwise and widthwise splicing; D. sanding and edge cutting on a board blank ; E, hot-press densification treatment on the board blank; F. carbonizing treatment. The manufacturing method of a finger joint laminated board, provided by the invention, is simple in technology; the finger joint laminated board manufactured according to the method has high structural strength, good stability and low adhesive consumption.

Description

technical field [0001] The invention relates to the technical field of decorative materials, and more specifically relates to a method for manufacturing a large-format carbonized plate. Background technique [0002] According to the regulations of GB / T21140-2007, finger-jointed lumber refers to the plank and square lumber made of sawn timber through finger tenon processing and gluing, and then the finished plank and square lumber is glued in the width direction. After knotting, the width is made into finger-jointed boards. The raw materials used are mainly fast-growing wood, among which poplar is the most widely used, with poor strength and low surface hardness. At present, finger-jointed boards are only used for concealed and unsightly surfaces such as furniture back panels. A position that is stressed and does not require strength. The current mainstream method is to overcome the plate deformation by changing the tooth structure in the width direction. For example, the in...
