How to distinguish between good and bad eco-boards?

See if there is a brand logo on the side of the product. Most of the eco-boards produced by regular companies have the company name on one side of the board, or the boards with edges sealed, and the buckles are also engraved with signs such as brand initials.

Check whether the color of the plate is even. The color of the regular eco-board is uniform, without obvious color difference, and there will be no incongruous color phenomena such as local spots, blocks and black spots, and there will be no defects such as fading, peeling and glue opening.

Put it in a slightly dark place and tilt the plate to see if the surface of the plate is smooth and there are obvious seams. Feel it carefully with your hands. The stronger the smoothness, the better the surface treatment of the plate. Inferior plate with rough and uneven surface. Wipe the disk with a key, the surface trace is not obvious, and basically no trace will appear as a good disk.

Measure the thickness of the plate. Use a tape measure to measure the thickness of different sides of the eco-board, or measure the thickness of several boards. The normal eco-board has a uniform thickness and stable plates, and the general thickness of eco-board is15-18 mm.

When multiple boards are put together, smell the boards. A good eco-board has no pungent smell. If there is a pungent smell, it means that the formaldehyde emission is high. The release amount of E0 grade formaldehyde is ≤0.5mg/L, and the release amount of E 1 grade formaldehyde is ≤ 1.5mg/L, and basically no odor is smelled.

If conditions permit, you can use a saw to cut a corner of the board, and observe its internal wood core structure, whether there are glue pouring, putty filling, internal cavities and cracks, or whether there are bad wood such as bark, drilling and knots in the middle spliced wood strips. Good slats are closely connected and layered.
