Wood stores CO2, which makes it a valuable material for reducing climate change. In essence, CO2 can be sequestered to a greater extent when more wood is used. Wood used …
In the last decade there has been a remarkable growth world-wide in the production of biomaterial-based composites. In this context, so-called wood plastic composites (WPCs) are today mainly used in …
Southern pine solid wood and wood fiber were reacted with acetic anhydride to various acetyl weight gains. The equilibrium moisture content (EMC) was determined on these specimens at 30%, 65% …
Acetylated Southern yellow pine (SYP) panels were exposed at a test field outside Stockholm, Sweden. After 7 months outdoors exposure at 45° facing south and 90° facing north, panels with …
Wood used in outside applications is susceptible to weathering and photo degradation, which often leads to surface discoloration, loss of brightness and surface deterioration. Research has shown that acetylated wood …
In the reaction of wood with acetic anhydride, when no catalysis or decrystalizing solvent are used, there is always hydroxyl functionality remaining after the reaction has gone to “completion” as …
The purpose of this study was to explore the possibility to surface densify acetylated solid wood. The aim of surface densification is to improve mechanical properties, such as hardness, at …
The primary purpose of growing rubber tree is to produce latex for rubber and tire industries. However, its wood has become a veritable alternative timber source in Nigeria. Rubber wood …
Mapping and visualization of structural changes due to the modification of wood would increase the understanding of chemical modification processes and facilitate optimization of the process parameters. The 2D and …
Wood is used as construction material because it’s strength and aesthetical properties from time immemorial. The shortages in wood application are bio-deterioration and swelling or shrinkage in variable humidity conditions. …
The decrease of water sorption is one of objectives of wood acetylation (Ac) with acetic anhydride (AA). The water absorption in acetylated wood might be decreased with rapeseed (Brassica napus) …
Acetylation has proven successful in limiting the hygroscopicity of wood, and improves both durability and dimensional stability (Rowell, 1996). It provides an environmentally friendly way to protect wood in outdoor …
Wood is a naturally hygroscopic material, and the atmospheric water molecules interact with sorption sites in the cell wall, causing changing moisture contents depending on the relative humidity of the …
Due to the inherent biological nature, wood is susceptible to microbial degradation. Traditionally, broad toxicity biocides have been used to protect wood against decay, but these are gradually being phased …
Plywood made from birch has superior mechanical properties compared with that made from most softwoods, which makes it suitable for structural application. Several previous studies have addressed birch plywood’s structural …
