The most environmentally friendly are: pure solid wood board and formaldehyde-free board.
I. Fiberboard (Density Board)
The full name is density fiberboard, which is made of wood and other plant fibers into powder and hot-pressed with glue.
Suitable for carved doors, but the moisture-proof performance is poor.
Second, particle board
Particleboard is made of wood fibers, that is, wood blocks, which are crushed into shavings and hot-pressed with adhesive. Density board is made of "powder" and particleboard is made of "broken", so the density is not as good as density board. Cut the cross section and you can see a hole in the middle. But the moisture-proof performance is better than that of MDF.
Density board and particle board are made of broken wood blocks and powder, so some bad manufacturers will add some other impurities to fill them, which will make the stability of the board much worse. Pay attention to buying this kind of board.
Third, the finger joint plate:
Also known as laminated board, multi-layer board and finger joint board, that is, plates made of small pieces of solid wood after deep processing like fingers. Because it is connected by solid wood blocks, the amount of glue used is also small, and the environmental protection coefficient is relatively high.
Fourth, splint
Also called multi-layer board and plywood, it is made of multi-layer sawdust by hot pressing. The hardness of the plate is also good, which is suitable for on-site cutting construction, but the amount of glue used will be a little more than that of the finger joint plate.
Five, formaldehyde-free board
Formaldehyde-free board is essentially a kind of wood-based board, but different from the previous wood-based board, it is required that formaldehyde-containing adhesives and other additives should not be used in the production process; Because no aldehyde is added, it has great advantages in environmental protection, but because the price of formaldehyde-free glue used will be a little higher than that of the same type of board.
