The choice of plywood mainly depends on its formaldehyde emission and bonding strength. If the glue strength of the plywood is not good, it will fall apart easily. When choosing, pay attention to whether the nominal thickness of the plywood is consistent with the actual thickness. Pay attention to the following points when choosing plywood:
1. There is a difference between the front and back of plywood. When selecting, the plywood should have clear wood grain, the front surface should be smooth and clean, not rough, and smooth and non-sluggish.
2. The plywood should not have defects such as damage, bruises, bruises, scars, etc.
3. There is no degumming of the glued whole board.
4. Some plywood is made by pasting two veneers with different textures together. Therefore, when choosing the plywood, the joints of the plywood should be tight and there is no unevenness.
5. When choosing plywood, pay attention to choosing plywood that does not loose glue. If the sound is brittle when knocking on each part of the plywood by hand, the quality is good; if the sound is dull, it means that the plywood has appeared loose glue.
