What should we pay attention to when choosing plywood?
1. We have studied the characteristics and uses of plywood before. So how do we choose?
There are two sides of the splint. When choosing plywood, the grain should be clear, the front surface should be smooth and smooth, not rough, and the hand should be smooth and smooth. When purchasing multiple plywood, the plywood with similar wood grain and color should be selected.
2. Plywood should not be damaged, bruised, hardened or scarred, and should be free from decay and deterioration.
3. No degumming of plywood.
4. Some plywood is made by sticking two veneers with different lines together. Therefore, we should pay attention to the tight joint of the splint in the selection, and there is no unevenness.
When choosing splints, attention should be paid to choosing non-dispersible splints. If the voice is crisp when the hand knocks on all parts of the plywood, the quality is good. If the voice is stuffy, it means that the splint has spread glue phenomenon.
6. Choose environmentally friendly plywood and pay attention to its formaldehyde release. Consumers should purchase high-quality environmental protection brand plates.
