Picking plywood should pay attention to the following aspects:
1) There are differences between the two sides of the splint. When picking, the plywood should have clear wood grain, smooth and smooth front surface, and no roughness, and it should be smooth without any feeling of lag; when purchasing multiple plywood, plywood with wood grain and similar color should be selected.
2) Plywood should not have defects such as breakage, bumps, hard wounds, tangles, etc., and there should be no decay or deterioration.
3) No degumming of plywood.
4) Some plywood is made by affixing two different lines of veneer together. Therefore, attention should be paid to the plywood patchwork where there is no unevenness.
5) When selecting splints, care should be taken to choose splints that do not loosen. If the plywood is hit by hand, the sound is brittle, which proves that the quality is good. If the sound is boring, it means that the plywood has been loose.
6) Choose environmentally friendly plywood, pay attention to the amount of formaldehyde released. Consumers should buy high-quality, environmentally-friendly brand plates.
