Firstly, we need to identify artificial decorative panels and natural decorative panels, with straight and regular textures and consistent colors. The natural decorative panel, on the other hand, has a highly variable and irregular texture pattern.

Secondly, the decorative appearance of the decorative panel is good. The material should be fine and uniform, with clear color and beautiful wood grain. The texture of the matching board and patchwork should be arranged according to a certain pattern, with similar wood colors and almost parallel seams and edges of the board. The surface color should be consistent and there should be no scars on the surface.

The quality of the base layer and surface wood veneer of the decorative panel should be good. The thickness and moisture content of the base layer should meet national standards, and whether alkali removal treatment should be carried out. The thickness of the surface wood veneer should meet the standard and should not be too thin. If it is too thin, it will penetrate the bottom and change, affecting the aesthetics.

The adhesive layer structure is stable and there is no peeling phenomenon. The joint between the wood veneer and the substrate must be tight, and there should be no bubbling, layering, or debonding between the wood veneer and the substrate, as well as between the internal layers of the substrate. You can use the knife prying method to test the bonding strength. Use a sharp flat blade to pry along the adhesive layer. If the adhesive layer is damaged but the wood is intact, it indicates poor bonding strength.

Smell the odor. If the pungent odor is strong, it indicates that the formaldehyde release exceeds the standard, which will seriously pollute the indoor environment and become more dangerous when used indoors. We can request a test report from the merchant to see if the product meets environmental standards.

When purchasing, it is necessary to choose products produced by legitimate manufacturers with markings indicating the category, grade, and manufacturer name of the decorative panel on the lower right corner of the back panel.
