How to identify the authenticity of plywood 1. How to tell the true and false of plywood 1. Observe the toughness of wood. The toughness of the eucalyptus core is higher than that of the poplar core. When it is turned, the eucalyptus core plywood is less likely to twist, and the poplar core plywood will appear softer. 2. To distinguish by color. The natural colors of these two materials are very different, and the counterfeiting of merchants only paints the surface of the wood, so the interior of the wood is still the original color. It can be distinguished by peeling the surface, the poplar is white, and the core of the eucalyptus is brownish red.
3. The weight. The density of the eucalyptus core and the poplar core is very different, and the eucalyptus core is much heavier than the poplar core under the same volume. You can feel it just by comparing with your hands. Second, how to distinguish the quality of plywood 1. Plywood should have clear wood grain, smooth and smooth front, no roughness, and smooth.
2. The appearance of good plywood is free from damage, knots, or bruises. Pay attention to the consistency of color and the overall feeling of wood grain. 3. The plywood should be free from defects such as breakage, bumps, insects, nail holes, dead joints, and burr grooves. 4. Some plywood are made of two different patterns of veneer glued together, so pay attention to the selection, the joints of the plywood should be tight, and there should be no unevenness. In particular, do not have two different patterns on a plywood, otherwise it will hinder reasonable use, cause waste, and affect the aesthetics of furniture. 5. If you can smell a strong pungent smell, it means that the plywood contains more harmful ingredients. This kind of plywood is not only of low quality, but also harmful to the human body.
