Jun 11, 2022
1. Understand the positive and negative characteristics of multi-layer boards: multi-layer boards can be divided into positive and negative sides. Therefore, when selecting, you should choose one with clear wood grain, smooth and tidy front, no roughness and flatness.
2. Pay attention to avoid all kinds of defects: multi-layer boards can't have defects such as damage, scars and bruises, so observe the surface of multi-layer boards carefully.
3. Look at the glue of multi-layer boards: when buying multi-layer boards, carefully observe whether there is degumming.
4. See if the splicing is good: sometimes multi-layer boards are made by splicing two single boards with different grain together. At this time, you need to carefully observe whether the lending is tight, whether there are obvious seams or uneven phenomena.
5. Choose a multilayer board that does not scatter glue: when shopping, you can try to knock the wrong parts of the multilayer board by hand. If the sound is brittle, it proves that the quality is better. On the contrary, if the sound is dull, it means that the multilayer board may have scattered glue.
