1. The texture and color of plywood
The texture of plywood is regular, beautiful and generous, with natural tones and clear wood grain. Conversely, poor-quality plywood has messy textures and deep colors.
2. Amount of glue for plywood
Saw the plywood into wooden strips, pull it open by hand, and see if the raw material in the middle of the product is in the shape of a wire. If the dough is separated from the dough, it means that the amount of plywood glue is insufficient. It is easy to crack during use, which will greatly reduce the use of plywood.
3. Toughness
Lean one end of the plywood against a fixed pier, make one end of the plywood high and the other low, and people stand on it and step on it. If the plywood breaks too much, it means that the inside of the plywood is not a whole core material.
4. Faults and hollow cores
Saw the plywood and look at the layout in the middle of the plywood. If there is a fault or hollow core, the plywood will bulge and crack.
5. Flatness of plywood
The surface of the plywood should be smooth, without obvious wormholes, cracks, short feet, and scars on the surface. After the plywood is removed, the concrete appearance can be neat and beautiful.
6. Boil in water and check the adhesion
Place the plywood in boiling water for two hours, check the plywood's gluing force, and see if the building template is cracked.
