Hygroscopicity is a general term used to describe a material's ability to absorb moisture from the environment. [31] There is no standard quantitative definition of hygroscopicity, so generally the qualification of hygroscopic and non-hygroscopic is determined on a case-by-case basis.
Equilibrium moisture content of wood versus humidity and temperature, according to the Hailwood-Horrobin equation. The equilibrium moisture content (EMC) of a hygroscopic material surrounded at least partially by air is the moisture content at which the material is neither gaining nor losing moisture.
Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method. There are two main reasons for drying wood: Woodworking
The relationship between water content and equilibrium relative humidity of a material can be displayed graphically by a curve, the so-called moisture sorption isotherm. For each humidity value, a sorption isotherm indicates the corresponding water content value at a given temperature. If the composition or quality of the material changes, then ...
Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, woodchips, or fibers. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper.
Wood science [1] is the scientific field which predominantly studies and investigates elements associated with the formation, the physical and chemical composition, and the macro- and microstructure of wood as a bio-based and lignocellulosic material.
Furniture preservation is the practice of maintaining the condition of furniture, especially antique or valuable wooden furniture. One of the most significant dangers to wooden furniture is humidity ; wood will tend to expand by absorbing water from the air when it is humid, and shrink when the air is drier. [ 1 ]
Wood was an important and common material in Greek furniture, both domestic and imported. [26] A common technique was to construct the main sections of the furniture with cheap solid wood, then apply a veneer using an expensive wood, such as maple or ebony. [26]
