Performance of Eucalyptus Lumber after Resin Impregnation and Heat Treatment
TLDR
In this article, the authors impregnated melamine urea-formaldehyde resin into wood before the heat treatment and showed that this combined treatment not only improved wood dimensional stability and durability, but also prevented the loss of mechanical strength.Abstract:
Heat treatment of wood under about 200 ℃ for a short period of time is a commonly used method to improve its durability and dimensional stability.However,the mechanical strength of wood after heat treatment usually decreases and the loss of strength has a negative effect on the application of heat-treated wood.To compensate for the strength loss,the authors impregnated melamine urea-formaldehyde resin into wood before the heat treatment.The results showed that this combined treatment(resin impregnation and heat treatment) not only improved wood dimensional stability and durability,but also prevented the loss of mechanical strength.read more

Changes of Chemical Composition, Crystallinity, and Fourier Transform Infrared Spectra of Eucalypt pellita Wood under Different Vacuum Heat Treatment Temperatures
TL;DR: In this paper, the authors proposed a method of improving dimensional stability and durability of wood by using vacuum heat treatment, which decreases the bending strength of wood and improves the dimensional stability of wood.
