appropriate plate under the board. Due to the large core plate belongs to the multi-layer structure, the quality of each layer of material will affect the overall quality. Daxinban produced by some small manufacturers in order to save costs, the use of the thin plate, resulting in large core bending less than adequate. If the bending force, such a large core plate easy to split from the two core pieces of wood cracks. In addition, many merchants sell pallets stacked in layers. When consumers choose pallets, look at the side of each of the pallets to see if they are the same. If the thickness of the same, indicating a higher level of sheet metal processing technology, quality is guaranteed. Xiaobian reminder: Identify the quality of Daxin Ban, you can also tap the surface of the board, listen to the sound of the differences, if the sound has changed, indicating the existence of a hollow sheet. The overall strength of such a plate is weak, uneven long-term force will distort the plate structure, deformation, affect the appearance and use. Fourth, environmental protection: environmental protection board to see the level of large-core board in the core board splicing and veneer and veneer veneer must use glue, so more or less the release
