  Choosing environmental protection board is an important part in the decoration process. Whether the board is good or not directly determines the quality and effect of home decoration. Now, let's teach you how to choose people to make boards.
  What is wood-based panel? Wood based panel is a board or molded product made of wood or other non wood plants as raw materials, which is separated into various unit materials after certain mechanical processing, with or without adhesive and other additives. Common wood-based panels include blockboard, plywood, along core board, integrated board, ecological board, etc.

  How to judge the quality of wood-based panel? To make a judgment, we can't ignore these indexes: moisture content, transverse static bending strength, bonding strength, immersion stripping and environmental protection grade.

1. Moisture content refers to the percentage of "water weight" in "dry wood weight". The moisture content determines the quality of wood products. When the moisture content exceeds 16%, it is prone to quality problems such as blistering, cracking, deformation, arching, discoloration and so on.
2. Transverse static bending strength is a physical and mechanical property. The higher the value of transverse static bending strength, the stronger the ability to resist bending deformation. In other words, the greater the transverse static bending strength, the stronger the plate.
3. The bonding strength is the bonding firmness between the surface and the medium plate. The surface bonding strength is low, and there is a great possibility of glue opening between the surface veneer and the substrate in the process of use.
4. Impregnation stripping is to judge the bonding performance of the test piece after impregnation and drying according to the degree of peeling of the adhesive layer. The impregnation stripping performance is poor, and the glue will open between the surface veneer and each layer of the substrate.
5. The environmental protection level is needless to say. If conditions permit, try to choose board products with high environmental protection level. After all, only by controlling the environmental protection of the substrate can we lay a good foundation for the overall household environmental protection.
When purchasing wood-based panels, it is suggested that we consider the core materials, appearance, enterprise qualification and environmental protection grade, so as to select satisfactory environmental protection panels more conveniently and quickly.
