Selected Physical Properties of Thermally Modified Spruce Wood
Original language description
Thermal modification of wood does not only change the color of the wood, it also changes wood properties that are closely related to its reaction to water (changes in dimensions, weight, density,...). These properties of thermally modified wood play an important role, limiting the use of thermally modified wood itself. These changes may be positive or negative depending on the wood species, thermal modification mode, the temperature used during the modification and other factors. The aim of this article is to broaden and collect knowledge about the effect of different thermal modification temperatures on selected physical characteristics of spruce wood. The results of the study show that thermal modification at a temperature range of 160C-210C has a statistically significant effect on the absorbability of thermally modified wood, as well as on tangential and volumetric swelling. Conversely, the effect of thermal modification on longitudinal swelling and a change in density during absorption was not proven.
