One of the largest issues with treatment on waterlogged wood is finding a way to remove the water in the wood but keep the water that is part of the material. Preventing cell wall collapse (which causes shrinking, cracking, and further damage) of the waterlogged wood while drying is the largest struggle and main goal of treatment.
These processes autoclave the treated wood, subjecting it to pressure and heat, along with nitrogen or water vapour to control drying in a staged treatment process ranging from 24 to 48 hours at temperatures of 180 °C to 230 °C depending on timber species. These processes increase the durability, dimensional stability and hardness of the ...
The relative humidity of air is defined as the partial pressure of water vapour divided by the saturated vapour pressure at the same temperature and total pressure (Siau, 1984). If the temperature is kept constant, lower relative humidities result in higher drying rates due to the increased moisture gradient in wood, resulting from the ...

Wood slabs can also become warped as a result of insufficient support from underlying shelf hardware (commonly referred to as sagging or bowing). [2] The types of wood warping include: bow: a warp along the length of the face of the wood; crook: a warp along the length of the edge of the wood; kink: a localized crook, often due to a knot
Let’s dive into why storms can make you feel like curling up for a nap: Nature's Melatonin One of the biggest culprits behind storm-induced sleepiness is a drop in barometric pressure, which ...
Thermally modified wood is engineered wood that has been modified by a controlled pyrolysis process of wood being heated to (> 180 °C) in an oxygen free atmosphere. This process changes to the chemical structures of wood's cell wall components lignin , cellulose and hemicellulose which decreases its hygroscopy and thus increases dimensional ...
