Plywood, which is cut into thin veneers by peeling or slicing logs, and then using adhesives to glue them into a plate-like material with three or more layers. Usually, an odd number of layers of veneers are used and the fiber directions of adjacent layers of veneers are glued perpendicular to each other. The length and width specifications of the plywood are generally 1220×2440mm, and the thickness specifications are 3, 5, 9, 12, 15, 18mm, etc. The main tree species are pine, poplar, and eucalyptus.

 

Plywood is also one of the most widely used materials for furniture making, and it is also one of the three major panels of wood-based panels. It can provide materials for aircraft, ships, trains, automobiles, buildings, and packaging boxes. A group of veneers is usually formed by gluing the adjacent layers of wood grains perpendicular to each other. The surface board and the inner board are usually symmetrically arranged on both sides of the layer or core. A slab made of glued veneers crisscrossed in the wood grain direction is pressed under heating or unheated conditions. The number of layers is generally odd, and a few have even numbers. The physical and mechanical properties of the vertical and horizontal directions are quite different. small. Commonly used types of plywood are three-plywood, five-plywood, and so on. Plywood can improve the utilization rate of wood and is the main way to save wood.

 

 

What are the main points of buying plywood?

 

1. We need to check the appearance of the plywood carefully to see if there are any small cracks or incomplete traces such as blisters. There is also a kind of plywood that is glued together by two veneers with different textures. Therefore, when buying, check whether the plywood is tightly seamed and whether there is unevenness. Furniture made of cracked plywood is not good-looking. Because some plywood is pasted, it is necessary to observe whether its color and texture are consistent. And whether the color of the wood is coordinated with the color of the furniture paint, the color of the plywood to be purchased must be coordinated with the overall effect of the decoration.

2. In the next step, we need to see if its workmanship is very fine. It is precise because the plywood is combined and pasted by two veneers, so there will be a difference between the front and the back. The surface layer of the plywood should have clear wood grain, the front side should be smooth and flat, and the backside should not have a rough and thorny feeling, and there should be no nodes. If the plywood is degummed, it will not only affect the construction but also cause pollution. Therefore, when selecting, you can tap the board lightly with your hands. If it makes a crisp sound, it means that the board sticks well. If it makes a heavy sound, it indicates that the board is degumming.
