Changing wood texture with combination of selective treatment and pressing

Abstract

Structural and anatomical models of alder wood have been developed on the basis of technical and physical models of wood. The models enable to solve the problem of penetrating changes in wood texture by combining selective treatment (impregnation) with two wood colouring agents in different directions of anisotropy, followed by uneven pressing. Specimens with the texture of mahogany, rosewood, walnut, etc have been obtained. Alder wood is pressed at an angle of 45° to the radial direction to obtain the texture of mahogany, at an angle of 90° – for a texture of rosewood. At the same time, physical and mechanical properties of modified wood correspond to similar indicators of wood of these species. The study of macro-and microstructure of pressed wood suggests that texture of the obtained material corresponds to the texture of rosewood and mahogany. It is possible to imitate any species of valuable wood using the obtained structural models and the developed techniques.

Stabilization of shapes and dimensions of compressed wood using chemical and physical methods

“…Hydro-thermal treatment is also used [4,5]. The most promising modification method is wood pressing [6][7][8]. However, this method has a significant drawback: increased formability.…”

Improving the quality of bog oak boards using microwave drying chambers

“…The purpose of this work was development of equipment and modes of microwave drying of cracking material (bog oak at the age of 100-150 and 2500-3000 years) by a combination of microwave drying and chemical treatment [10,11]. Optimized drying modes will increase the quality of bog oak in terms of cracking defect by three or four times.…”
