Properties of Wood and Wood Based Materials Subjected to Thermal Treatments under Various Conditions

چکیده
Thermal modification is a well-known process to change the dimensional stability, hygroscopicity, and biological resistance of wood due to chemical modifications of wood cell components. In this study, we reviewed several characteristics of heat-modified solid wood and wood-based panels under various temperatures, durations and pressure. Thermal compressing treatment could affect drying speed, equilibrium moisture content, dimensional stability, durability, surface quality, modulus of rupture, modulus of elasticity, janka hardness, surface abrasion strength, nail/screw withdrawal strength, and shear modulus of wood. The hygroscopicity of wood can be also affected by heat.

Nanotechnology in Wood-based Composite Panels
Wood is a naturally renewable material with both continuous and isolated pore systems. Wood-composite panels have the privilege of offering a homogeneous structure to be used as constructional and structural materials. However, its nature makes it susceptible to biological wood-deteriorating agents, water absorption and thickness swelling, fire, etc. Using nano-materials are very easy in the wo...

متن کاملPerformance Characterization of Coatings on Treated-wood
Coating performance is greatly influenced by the properties of the wood substrate. This study was focused on evaluating the performance of coatings on both preservative- and thermally-treated wood. A number of commercially formulated semi-transparent stains Alkyd, Alkyd-Acrylic and PU were applied on four different types of preservative treated and heat-treated wood and their performances were ...
متن کاملThe effect of Sulfuric acid and Maleic acid on characteristics of nano-cellulose produced from waste office paper
Present paper examines the effect of acid type and hydrolysis conditions on morphology, size, yield and crystallinity of produced cellulose nanocrystal (CNC). Cellulose obtained from waste office paper was hydrolyzed under the same conditions by Maleic acid (MA) and Sulfuric Acid (SA) in separate treatments. Also this cellulose was hydrolyzed under different timing and temperature by MA and SA...
