In a cross section of a wood cells microscopically thicker and less distinguished lumen wall, and

Freshly cut wood contains a lot of water, one third to half of its total weight. The process to
remove this water before processing is called dry wood, and is done for many reasons. Dry
wood is much more durable than fresh wood; It is much light
DENSITY AND GROSS DENSITY
In the wood distinguishes between density and bulk density. Density means the ratio of mass to
volume of wood cell cavities. The substance of the cell wall is composed of the same material in
all cells. Therefore, in all woods su
ACOUSTIC PROPERTIES OF WOOD
Sound insulation against external airborne noise: insulation materials against these types of
noise depend on its weight, increasing with increasing isolation it. The wood having a specific
gravity low is a very bad insulation,
The Postforming is a process that transforms bits and pieces of the board with straight edge

For postforming boards requires a prior step that consists in measuring Melamine boards strip

MICROSCOPIC STRUCTURE OF WOOD
If the wood is analyzed through a microscope is found that, like any living being, is constituted
by elongated cells generally arranged mostly in the shaft axis direction, without protoplasmic
content. Only a small percentage
