Plywood Density

- Oct 26, 2017 -

The density of the plywood is around 0.6.

        Plywood for aircraft, ships, trains, cars, construction and packaging and other materials. A group of veneers are usually made in the direction of the adjacent layers in the direction of the adjacent layers. Generally, the panels and the inner plates are arranged symmetrically on either side of the center layer or the core. With the veneer after the wood by the direction of criss-cross the composition of the slab, heated or not heated under the conditions of suppression. The number of layers is generally odd, and there are even few. Vertical and horizontal direction of the physical and mechanical properties of small differences. Commonly used plywood type plywood, penta and so on. Plywood can improve wood utilization and is a major way to save wood. The general length and width specifications are: 1220 × 2440mm, while the thickness specifications are generally: 3,5,9,12,15,18 mm and so on. The main species are: camphor, willow, poplar, eucalyptus and so on.


Plywood

Plywood density:

        The higher the plywood density, the better the quality. Generally larger than the same kind of decoration wood. The greater the unit pressure when gluing, the greater the density of the plywood. As the wood at high temperature easy to produce plastic deformation, hot pressing glue than the cold compression of the compression rate is greater. As the plywood from the criss-cross the preparation of the veneer, the thermal conductivity is lower than the same species of wood.
