Fine grinding of wood – Overview from wood breakage to applications

Interactions between Fine Wood Decomposition and Flammability

Fire is nearly ubiquitous in the terrestrial biosphere, with profound effects on earth surface carbon storage, climate, and forest functions. Fuel quality is an important parameter determining forest fire behavior, which differs among both tree species and organs. Fuel quality is not static: when dead plant material decomposes, its structural, chemical, and water dynamic properties change, with...

Acetylation of wood – A review

Wood is a porous three dimensional, hydroscopic, viscoelastic, anisotropic bio-polymer composite composed of an interconnecting matrix of cellulose, hemicelluloses and lignin with minor amounts of inorganic elements and organic extractives. Some, but not all, of the cell wall polymer hydroxyl groups are accessible to moisture and these accessible hydroxyls form hydrogen bonds with water. As the...

Ipolyhydric Alcohols from Wood

Dermatitis from Mansonia wood.

Homer and Wigley (1936) reported a case of dermatitis due to Mansonia wood (Sterculiacea altissima) and in his annual report the Chief Inspector of Factories (1936) also reported that the dust of this wood could give rise to serious symptoms and in this respect compared it with African box wood. There are apparently no other reports of the possible dangers relating to the use of this wood, and,...

Properties of Wood and Structural Wood Products

Wood differs from other construction materials because it is produced in a living tree. As a result, wood possesses material properties that may be significantly different from other materials normally encountered in structural design. Although it is not necessary to have an in-depth knowl­ edge of wood anatomy and properties, it is necessary for the engineer to have a general understanding of ...
