Moisture-resistant board features

Environmental friendliness: This mainly refers to whether the glue used is aldehyde glue or melamine glue. The latter is more environmentally friendly, but it's not easy for the average customer to distinguish. Smelling it isn't always reliable; some boards lose their smell over time, while others develop an odor after being sealed for a long time. The smell is also much stronger in hot weather. A better method is to check both the inspection report and the markings on the board. However, relying solely on the inspection report isn't enough, as a factory may produce boards of different grades, and the inspection report might not reflect the grade. Checking the grade markings on the board is much more reliable. Generally, manufacturers and sellers can make arbitrary claims and issue invoices arbitrarily. They can deny what they say verbally and claim errors in written documentation, saying they can simply redo it. But marking the product itself is a different story.

Physical properties: These include properties such as bonding strength, resistance to deformation, and overall strength. These are generally difficult for those unfamiliar with the subject to determine. A good indicator is that the particle size of the moisture-resistant board shouldn't be too large, as this would result in insufficient strength, nor too small, as this might indicate sawdust. Cut it open and look at the cross-section (it should be irregular, you can't see it if it's flat), see how many needle-like sheets there are.

Moisture resistance: This is even harder to judge, you have to take different brands home and soak them in water to see.
