Impregnation Properties of Nigerian-Grown Gmelina arborea Roxb. Wood

open access: yesForests, 2022
The success of any wood treatment process and the measure of protection conferred on treated wood are determined by the uptake and penetration of the treatment chemicals, in addition to the efficacy of the chemicals used for the treatment.

Fast Preparation of High-Performance Wood Materials Assisted by Ultrasonic and Vacuum Impregnation

open access: yesForests, 2021
In the absence of high-quality hardwood timber resources, we have gradually turned our attention from natural forests to planted fast-growing forests. However, fast-growing tree timber in general has defects such as low wood density, loose texture, and ...

Wood impregnation

open access: yes, 2016
Wood impregnation is one of the oldest and the most frequently used techniques to protect the wood. This treatment offers a wide range of protection depending on used impregnants (preservatives). Impregnation can make the wood more resistant to decay, less flammable, more dimensionally stable, harder, stronger, more UV stable resistant and many more ...

Paraffin Pickering Emulsion Stabilized with Nano-SiO2 Designed for Wood Impregnation

open access: yesForests, 2020
Wax impregnation is an effective approach to improve wood water resistance. However, melted waxes require special equipment and cannot penetrate deep enough into wood. Recently, wax emulsions show excellent efficiency in wood modification. In this study,

Wood impregnation of yeast lees for winemaking

Food Chemistry, 2015
This study develops a new method to produce more complex wines by means of an indirect diffusion of wood aromas from yeast cell-walls. An exogenous lyophilized biomass was macerated with an ethanol wood extract solution and subsequently dried. Different times were used for the adsorption of polyphenols and volatile compounds to the yeast cell-walls ...

Effects of Potassium Hydroxide Impregnation on Wood Pyrolysis

Energy & Fuels, 2009
The pyrolysis of a packed bed of fir wood particles, after impregnation with KOH, is investigated. For a heating temperature of 800 K, maximum variations in the pyrolysis characteristics are observed for KOH concentrations in wood below 1%. Decomposition temperatures become lower (35−70 K), and conversion times are rapidly more than halved.

IMPREGNATED WOOD VENEERS

Anti-Corrosion Methods and Materials, 1955
Chemical engineers have always been interested in non‐metallic materials because they are non‐corroding and extensive use has been made in the past of wood. Wood, however, suffers from many disadvantages, chief of which are its dimensional instability and its susceptibility to bacterial and insect attack.
