Problems solved by technology

[0005] Because Rong'an fir is different from other raw materials, in the current existing technology, the processing of Rong'an fir is more simple drying and bonding according to the traditional wood manual or simple mechanical processing methods handed down from word of mouth, resulting in Due to environmental changes in the process of making processed plates into finished products, their internal moisture content also undergoes major changes, which are prone to deformation and cracking, which is not conducive to the development of this industry
On the other hand, in order to overcome the above situation, more waterproof and anti-cracking agents are added to the current board treatment, artificially increasing the release of chemical substances from the board, which does not meet the needs of modern people in pursuit of a green life
Therefore, it is of great significance to improve product quality and promote the development of the industry to improve the stability of the quality of solid wood panels during the use of solid wood panels and to achieve the purpose of people pursuing high-quality furniture. There is very little research on this area in the prior art

Embodiment 1

[0035] A method for controlling the flatness of a solid wood ecological board, comprising the following steps:

[0036] a. Scraping the solid wood core: First use wood chips to fill up the recesses of the solid wood core with a diameter > 15mm, and then use ash scraping material A to scrape the solid wood core; wherein, the solid wood core is 3cm in width, 45cm in length, It is formed by splicing 12mm thick slats, and the slat raw materials are selected from common Chinese fir;

[0037] Wherein, the ash-scraping material A comprises the following raw materials by weight: 20 parts of wood bran, 200 parts of glue, and 7 parts of flour.

[0038] b. Solid wood board core sanding: the solid wood board core is evenly sanded on both sides, and the flatness of the same board after sanding is within -2 ~ 2mm;

[0039] c. The solid wood core and the eucalyptus chips are laminated and pressed to form a rough board: the solid wood core is coated with glue on both sides, and after air-dry...

Embodiment 2

[0046] A method for controlling the flatness of a solid wood ecological board, comprising the following steps:

Abstract

The invention relates to the technical field of solid wood plate processing, in particular to a solid wood ecological plate flatness control method. The method comprises the following steps that a, solid wood plate core ash scraping is conducted; b, solid wood plate core sanding is conducted; c, the solid wood plate core and a eucalyptus sheet are attached and pressed to be formed, and a blank plate is obtained; d, the blank plate is subjected to standing and maintained for 10-45 days; e, blank plate ash scraping is conducted; f, blank plate sanding is conducted; g, the blank plate and poplarbark are attached, and a blank plate is obtained; and h, blank plate sanding is conducted. The solid wood ecological plate flatness control method is provided, formaldehyde release in the method is the E0 level, and the solid wood plate can be directly used in a room; in the using process, the solid wood plate flatness change is small, related standard requirements are met, and the appearance canmeet the requirements of people for high-quality furniture plates under normal usage even under the severe conditions.

Description

【Technical field】 [0001] The invention relates to the technical field of solid wood board processing, in particular to a method for controlling the flatness of a solid wood ecological board. 【Background technique】 [0002] Rong'an County is a major forestry county in the country and a key county for national ecological protection. It has a total area of ​​1.25 million mu of Chinese fir, a stock volume of 4.13 million cubic meters of Chinese fir, and an annual harvest of 120,000 cubic meters of Chinese fir. [0003] Environmental protection furniture has become a new force in the furniture industry, which can better meet the new needs and life concepts of modern people in pursuit of environmental protection, ecology and health. Therefore, the new ecological board will be a new force in the current industry. The ecological board has the advantages of small deformation rate, less glue consumption, etc., coupled with the advantages of the overall solid wood core structure, it wi...
