Preparation method of solid wood flooring blank for heat modified floor heating system

Abstract

The invention provides a preparation method of a solid wood flooring blank for a heat modified floor heating system. The dried solid wood flooring blank is subject to lower temperature heat treatment, lower temperature drying, high temperature drying, high temperature heat treatment, cooling and humidify adjustment treatment and six processes for solid wood flooring blank maintenance, wherein the six processes include three times of heat treatment, two times of drying and one time of maintenance. The processes of the method are completed in a conventional wood drying kilns, wood high temperature carbonization rooms and wood maintenance rooms. By means of the processes, through lower temperature heat treatment and lower temperature drying in the early stage, defects of cracking, deformation and the like caused by uneven internal stress and uneven water content are reduced, and the yield of the solid wood flooring blank is improved.

Description

technical field [0001] The invention belongs to the field of solid wood floor processing and preparation, in particular to a method for preparing a heat-modified solid wood floor blank for floor heating. Background technique [0002] The existing thermal modification of wood is to put the wood in a high temperature, anaerobic or low oxygen environment of 160-220 ° C for a period of heat treatment. High temperature carbonization will reduce the concentration of free hydroxyl groups in the wood components and improve the wood. Dimensional stability. It is mainly aimed at coniferous materials and soft broad-leaved materials with relatively loose materials, while floor materials are generally hard broad-leaved materials with relatively high density, darker color and relatively stable material properties. If this technology is directly used for solid wood floor blanks, Not only will it cause cracking and degradation of solid wood floor blanks, but there will also be some problem...

Problems solved by technology

It is mainly aimed at coniferous materials and soft broad-leaved materials with relatively loose materials, while floor materials are generally hard broad-leaved materials with relatively high density, darker color and relatively stable material properties. If this technology is directly used for solid wood floor blanks, Not only will it cause cracking and degradation of solid wood floor blanks, but there will also be some problems in the color and luster of the wood, the mechanical strength, and the adhesion of the paint film.
