In order to give you a better understanding of poplar plywood packaging, poplar plywood packaging manufacturers deliberately constitute its principles, characteristics, and uses for everyone to be a detailed introduction.
1, outlined the composition of poplar plywood principles:
(1) symmetry principle: in the poplar plywood symmetrical central plane on both sides of the corresponding layer within the unit, its tree species, thickness manufacturing methods, texture direction, moisture content should be the same.
(2) the principle of interlayer texture arrangement: a right angle or a certain angle to reduce anisotropy, the direction of fiber alignment to play a longitudinal strength dimensional stability characteristics.
(3) the principle of odd layer: the group did not follow the principle of symmetry, inter-layer texture principles, are generally followed the odd principle 5. Write dry heat production of plywood process.

2, what is plywood? Brief description of the characteristics of plywood:
Plywood consists of three or more than three veneer according to the principle of symmetry, adjacent to each other wood grain direction perpendicular to the group of billet formed plate. Usually, the face plate and the inner layer plate are symmetrically arranged on both sides of the center layer or the core. Features: (1) High strength ratio, (2) Large format, (3) Beautiful appearance, (4) Anisotropic reduction, (5) Retain the advantages of the natural wood and hide some defects.
3, plywood by purpose, number of layers, the water resistance of the rubber layer which is divided into several?
Special plywood (with special properties, such as flame retardant, anti-corrosion, pest control and other plywood) by layer: three-layer plywood (non-specialized plywood, yield the most widely used, the most typical plywood) , Five plywood, multi-layer plywood.
According to the water resistance: Ⅰ type plywood (weather-resistant plywood, for outdoor use, through the boiling test), Ⅱ type plywood (water plywood, for wet conditions, through 63 ± 3 ℃ hot water immersion test) Ⅲ type plywood (not resistant to moisture plywood, for use under dry conditions, through the dry test).
Through the poplar packaging plywood manufacturers, we constitute the principles of plywood, features and uses are more clear it. Finally, the three sources of wood I wish you good health, family happiness.
