The base material of the plywood is wood and formed into a veneer or a thin wood cut from wood, and is laminated into three or more layers by a special adhesive.
It has good sound absorption and sound insulation performance; the particleboard is insulated and absorbs sound; the interior is granular with cross-staggered structure, the directions of each part are basically the same, and the lateral load-bearing capacity is good;
There are many reasons for the bubbling of the plywood. It may be that the raw material is unqualified, the quality is not good, and when the surface smoothness of the substrate is relatively poor, it is easy to cause bubbling of the finished multi-layer board.
The quality of particleboard varies greatly. The wasteboard made of sawdust and sawdust is also made of large-scale planks made of logs. The formaldehyde content of this facade is also different.
Particle board is also called bagasse board. It is made of wood or other lignocellulosic material. It is a kind of wood-based board which is glued under the action of heat and pressure. It is also called particle board.
