1. Observe the surface of the plywood
Observe whether there are cracks, worm holes, blisters, stains and other bad marks on the surface. Some plywoods are pasted together with two veneers with different textures, so when purchasing, check whether the seams of the plywood are tight and whether they are high or low. inequity.
2. Measure the actual thickness of the plywood
Measure whether the actual thickness of the plywood matches the nominal thickness when the merchant sells it, so as to avoid cutting corners.
3. Pay attention to the choice of plywood’s gluing properties
For boards with stable glue layer structure and no glue-opening phenomenon, you can tap each part of the plywood by hand when purchasing. The sound is brittle and usually indicates good quality. If the sound is dull, it means that the glue quality is not good. The plywood method can also be used to test the gluing performance, that is, use a sharp blade to pry the plywood along the glue layer. If the glue layer is damaged but the wood is not damaged, it means that the gluing quality is poor.
4. Observe whether the color and texture are consistent
Since some plywood is pasted, it is necessary to observe whether its color is consistent, whether the texture is 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 should be coordinated with the overall effect of the decoration.
5. Check whether the workmanship of the plywood is fine
Since plywood is made of two veneers pasted together, there must be front and back sides. The surface layer of the plywood should have a clear wood grain, the front side should be smooth and smooth, and the back side should not have a rough and thorny feeling, and it is best not to have nodes. If the plywood is degummed, it will not only affect the construction, but also cause pollution. Therefore, you can tap the plate lightly when selecting it. If it makes a crisp sound, it means that the plate is well adhered.
6. Choose environmentally friendly plywood Do not buy plywood with a distinct pungent odor.
