look
The surface board of high-quality eco-board is smooth and flat as a whole, and the thickness of the board core is uniform. It is necessary to observe whether the multi-layer board is peeled off. If there is no difference in the texture of a pile of veneers, most of them are covered with artificial veneers, and whether the veneers are dyed or not can be identified only by dipping them in some water and rubbing them gently.
listen to
If the eco-board stands on the ground and knocks at different positions, if the knocking is very different, then there may be quality problems. If the tapping is even, the quality of the board is still very good.
touch control
Touch the surface of eco-board or multi-layer board with your hands. A good plate should feel dry and smooth, and there is no wave when touching it horizontally, indicating that the plate has low moisture content and good flatness.
smell
If the eco-board emits a faint fragrance, it means that the formaldehyde content of the board is low; Conversely, if the smell is pungent, the formaldehyde content is high.
see
If conditions permit, it's best to cut open the eco-board and observe it to see whether the internal quality, slats are dense, whether there are obvious gaps, and whether there are rotten battens in it, because there may be bugs hatching in the rotten battens, which will easily be eaten by insects in the future.
cheque
Check the trademark, certificate, anti-counterfeiting mark, formaldehyde test report, environmental protection mark and so on of the eco-board in detail.
price
It's hard to say, because the prices of different manufacturers in different regions vary greatly, but in the same region, the prices of plates with the same quality are basically the same. So don't be greedy and cheap when buying. It is suggested to choose brand products such as Bunny, Zhongmu Woodcutter, Jingyiliangmu, etc. These products are well-known and recognized by various national authorities.
