Plywood is one of the commonly used materials for furniture. It is one of the three panels of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, construction and packaging. At present, the market is filled with a large number of low-priced Liuqi core plywood. In the case of fire-retardant plywood, this is the surface coloring treatment of the poplar core board, so the appearance is basically the same as that of the Liuqi core board. Today, I will show you how to distinguish the true and false of plywood and how to distinguish good and bad plywood.

First, how to distinguish the true and false of plywood

1. Observe the toughness of the wood . The toughness of the willow core is higher than that of the poplar core. The plywood core plywood is not easily twisted when flipped, and the poplar core plywood will appear softer.

2. Distinguish by color. The natural color of these two materials is very different, and the business is only painted on the surface of the wood, so the interior of the wood is still the original color. The surface can be distinguished by peeling off the surface, the poplar is white, and the willow core is brownish red.

3, 掂 component. The density of the willow core and the poplar core are very different. The same volume of the willow core is much heavier than the poplar core. You can feel it by hand with a contrast.

Second, how to distinguish whether plywood is good or bad

1. The plywood should have a clear grain pattern, and the front surface should be smooth and smooth, not rough, and should be flat.

2. The appearance of good plywood is not damaged, frugal or hard. Pay attention to the consistency of color and the overall feeling of wood grain.

3, plywood should not be damaged, broken, insects, nail holes, dead knots, burrs and other defects.

4. Some plywood is made up of two different kinds of veneer glue sticks together, so pay attention to the selection when the joints are tight, no unevenness. In particular, there should be no two different lines on a plywood board, otherwise it will hinder reasonable use, resulting in waste and affecting the appearance of furniture.

5, if you can smell a strong pungent smell, it means that the plywood contains more harmful components. This kind of plywood is not only of low quality, but also harmful to the human body.
