plywood is one of the commonly used materials for furniture. It is one of the three major panels of wood-based panels. It can also be used as a material for aircraft, ships, trains, automobiles, buildings, and packaging boxes. At present, the market is flooded with a large number of low-priced eucalyptus core plywood. flame retardant plywood is actually made of poplar core plywood with surface coloring treatment, so the appearance is basically the same as that of eucalyptus core plywood. Today I will introduce how to distinguish.
Plywood is true and false and how to distinguish between good and bad plywood.
Ⅰ. How to distinguish the authenticity of plywood
1. Observe the toughness of wood. The toughness of the eucalyptus core is higher than that of the poplar core, and the eucalyptus core plywood is not easy to be twisted when it is turned, while the poplar core plywood will appear softer.
2. Distinguish by color. The natural colors of these two materials are very different, and the counterfeit business only paints colors on the surface of the wood, so the interior of the wood is still the original color. It can be distinguished by peeling off the surface. The poplar is white and the eucalyptus core is brownish red.
3. Weigh the amount. The density of the eucalyptus core and the poplar wood core are very different. Under the same volume, the eucalyptus core is much heavier than the poplar wood core.
Ⅱ. how to distinguish whether plywood is good or bad
1. Plywood should have clear wood grain, smooth and clean front, not rough, and flat.
2. The appearance of good plywood is not damaged, knots, or flaws. Pay attention to the consistency of the color and the overall feel of the wood grain.
3. The plywood should not have defects such as damage, bumps, bugs, nail holes, dead knots, burrs and groove marks.
4. Some plywood suppliers near me manufacturing plywood is made by patching together two kinds of veneer glues with different textures, so when choosing, pay attention to the joints of the plywood should be tight and there is no unevenness. Especially a piece of plywood should not have two different lines, otherwise it will hinder the reasonable use, cause waste, and affect the appearance of the furniture.
5. If you can smell a strong pungent smell, it means that the plywood contains more harmful ingredients. This kind of plywood sheet is not only of low quality, but also more harmful to the human body.
