Problems solved by technology

[0007] 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, which artificially increases the release of chemical substances from the board, which does not meet the needs of modern people's pursuit of green life.
Therefore, the research on the process of making solid wood ecological boards with Ronganxiang fir as the main raw material, especially how to effectively control the water changes in the production process, is of great significance for improving product quality and promoting industry development. very little research

Abstract

The invention relates to the technical field of solid board processing, in particular to a method for controlling the moisture content of a solid wood ecological board. The method for controlling themoisture content of the solid wood ecological board comprises the following steps of a, processing wood raw materials; b, cutting the raw materials into platens; c, controlling the moisture of the platens; d, splicing the platens to form a board core; e, controlling the moisture of the board core; f, controlling the moisture of eucalyptus chips; g, forming a laminating board through the eucalyptuschips and the board core; and h, controlling the moisture of the laminating board. According to the method for controlling the moisture content of the solid wood ecological board, a multi-step moisture control method is adopted for key materials from the raw materials to the finished product, the product moisture is controlled to be in a reasonable and stable environment, the product is not proneto deforming or cracking in the using process, and the using quantity of chemical waterproof reagents is reduced.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of solid wood board processing, in particular to a method for controlling the moisture content of a solid wood ecological board. [0003] 【Background technique】 [0004] 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. It was assessed by the state in 2010 It is a national-level forestry county. In 2012, it was listed as a pilot county for the national timber strategic reserve base by the Forestry Department of the Autonomous Region. It received an investment of 8.8 million yuan from the central government to build 600 mu of Cedar Sufeng forest and cultivate 70,000 mu of young and middle-aged forest. It is expected that in 2020 the whole county will The area of ​​Xi...
