Do you really know anything about plywood?

what is plywood?

Plywood, in fact, is a kind of sheet made of adhesive. The front side of the plywood is called the “panel”, and the opposite side is called the “backplane”. The middle one is called the “core plate”. Under normal circumstances, the board core is made of some wood cut into thin slices, and then paste these sheets layer by layer according to the direction of the wood grain, and then put the panel and the inner board on both sides of the board core or the center layer, and then use the coated veneer, according to the direction of the wood grain staggered superposition into the board blank, and then after heating and pressing. Common plywood tired heart has plywood, plywood and so on. Common plywood materials are poplar, willow, beech and so on.

what are the advantages of plywood?


Because plywood is some thin skin bonded together, these sheets also form a right Angle structure, as we all know, the right Angle structure will be better strength, not easy to crack and not easy to bend.


Plywood is composed of some thin skin bonding, so the price will be lower than other sheet prices.

Wide range of use

Plywood is not only used in home decoration, such as aircraft, ships and containers have places that need to use plywood.


How to buy plywood?


The wood grain of good quality plywood is relatively clear, and it is smooth and flat to touch, and there will be no cracking and bulging phenomenon. Of course, there are some plywood above there will be cracks, frizz and other phenomena, these plywood are inferior to polish their eyes oh!


The strength of the plywood also determines the quality of the plywood, the method of checking the strength is very simple, that is, pick up one end of the plywood and listen to whether there will be a “creak” sound, if there is so that the strength is not high.

Moisture content

The moisture content of the board is very important, if the moisture content is too high, then the board is prone to cracking and deformation, the way to check is if you feel cold when you touch the plywood then the moisture content is relatively high plywood.

Board core

Board core is an important factor that determines the quality of plywood, although in the middle of the plate we can not be identified by the naked eye, but you can use the hand to knock, if the sound is not uniform is the core of the hollow phenomenon, plywood joint is tight is also crucial, can not appear uneven phenomenon.
