Performance Requirements For Decorative Veneer Veneer Plywood

①The national standard stipulates that the moisture content index of decorative veneer veneer plywood is 6% to 14%.

②The surface bonding strength reflects the bonding strength between the decorative veneer layer and the plywood substrate. The national standard stipulates that this index should be ≥ 50MPa, and the number of up-to-standard specimens should be ≥ 80%. If this index is unqualified, it means that the bonding quality between the decorative veneer and the base plywood is poor, which may cause the decorative veneer layer to open and bulge during use.

③Dipping and peeling reflects the gluing performance of each adhesive layer of decorative veneer veneer plywood. If this indicator is not qualified, it means that the glue quality of the board is poor, which may cause the glue to open during use.

④ Formaldehyde release limit. This indicator is a mandatory national standard implemented in my country from January 1, 2002, which is the "birth certificate" for related products. It is also the "market access certificate" for related products. Since July 1, 2002, products that fail to meet this standard are not allowed to enter the market circulation field. Exceeding the limit of formaldehyde will affect the health of consumers. The standard stipulates that the formaldehyde emission of decorative veneer veneer plywood should reach: E1 level ≤ 1.5mg/L, E2 level ≤ 5.0mg/L.
