As far as wallboard is concerned, it is nothing more than fiberboard (density board), particleboard (solid wood particle board), multilayer board (multi-layer solid wood board), large core board (joinery board), solid wood mosaic board and original wood board. Density board and particleboard shall not be used as wallboard. First, the amount of glue is large and there is a hidden danger of formaldehyde; Second, in humid weather, the arch of the foot expands and collapses; Third, it is airtight, expensive and laborious, and the operation is useless. For example, I think there are more layers of criticism of the family and less space for the circle. Multilayer board and large core board have better stability than density board and particleboard, and their disadvantages are the same as the latter.

It is suggested to use solid wood board and original wood board as wallboard instead of melamine tissue paper. Both of them completely retain wood fibers, naturally interact with the outside world, expand and contract when wet, and intelligently adjust the environmental humidity. The process of sticking melamine paper towels is an "eco-board", which completely isolates the board itself from the outside air, and the airtight formaldehyde is also closed, so you can't detect it, but it is slowly released at 15. However, all solid wood will expand and contract with the change of air humidity, so there will be many warping, cracking and moldy phenomena in solid wood furniture.

It is strongly recommended to use brand oil oak stabilized solid wood plywood as wallboard. This kind of plywood is deformation-resistant, formaldehyde-free, intelligently adjusts indoor humidity, and can create a healthy and beneficial environment when used in a large area indoors. It has obtained a national patent.

Oil oak, a tree species of eucalyptus in Myrtaceae, is tough, dense, moth-resistant and corrosion-resistant. Rich in a variety of natural essential oils beneficial to human health, such as eucalyptol, pinene, rest anisaldehyde, piperidone, fennel, etc., it can strongly release phentermine and negative ions (air vitamins). Its special fiber structure can strongly absorb and release water, and shrink through wet expansion. Large-scale indoor use can achieve the effects of sterilization, anti-inflammation, air purification, immunity improvement, blood pressure reduction, tranquilization, brain strengthening and anti-aging.
