How to choose decorative veneer veneer plywood
In recent years, in plywood production, derived from many varieties, of which the most important one is in the original plywood on the surface of a thin paste decorative veneer veneer, called decorative veneer plywood market referred to as decorative board or panel.
It is worth noting that the common decorative panels are divided into natural wood veneer panels and artificial wood veneer panels. The natural wood veneer is a veneer veneer made of precious natural wood, which is processed by cutting or rotary cutting. Artificial thin wood is the use of relatively low price of logs cut into veneer, after a certain process of glue made of wood, and then cut into a decorative pattern with a fine decorative wood.
Is often a good pattern usually natural wood veneer veneer veneer veneer stickers, high-value species, such as cypress, pear wood, oak, Manchurian ash etc.. But in the name of goods, it shall be noted, for example, called “cypress plywood” or “plywood ashtree slices”, or “cherry wood trim”.

Stable layer structure, no glue phenomenon. Attention should be paid to the surface between the veneer and the substrate, the inner layer of the substrate can not appear between the drum, layered phenomenon. Testing the bonding strength by means of a knife. This is the most intuitive testing methods of bonding strength, with a sharp blade along the open flat layer. If the layer damage, and the wood is not destroyed, that poor bonding strength.
To choose a low formaldehyde emission plate. Decorative panels with pungent odor should be avoided. Because the greater the smell, indicating that the higher the amount of formaldehyde emissions, the more pollution, the greater the harm.
