National standards for decorative veneer veneer plywood performance requirements: China is the recommended standard GB / T 15104-94 "decorative veneer veneer board", the vast majority of enterprises to implement the implementation of this standard. The standard on the decorative veneer veneer plywood in the appearance of quality, processing accuracy, physical and mechanical properties of the three aspects of the indicators. Its physical and mechanical performance indicators are: moisture content, surface bonding strength, impregnation stripping. GB 18580-2001 "interior decoration materials, wood-based panel and its products in the formaldehyde release limit" also provides the product of formaldehyde emission limit indicators.

① national standards for veneer veneer veneer moisture content index of 6% to 14%.

② surface bonding strength reflects the decorative veneer layer and the plywood between the bonding strength. National standards that the indicators should be ≥ 50MPa, and the number of standard test pieces ≥ 80%. If the index is not qualified, indicating that the decorative veneer and the substrate plywood of the poor quality of bonding, in use may cause the decorative veneer layer opening.

③ impregnated peeling is reflected in the decorative veneer plywood veneer gluing performance. The failure of the indicators that the quality of the poor quality of the plate, in use may cause open plastic.

④ formaldehyde release limit. The indicator is China's January 1, 2002 implementation of the mandatory national standards, which is related products, "Zhunsheng Zheng", from January 1, 2002 onwards to reach the standard products are not allowed to produce; Is also related products, "market access card", from July 1, 2002 can not reach this standard products are not allowed to enter the market circulation. Formaldehyde limit will affect the health of consumers. Standard requirements of decorative veneer veneer plywood formaldehyde emission should be: E1 level ≤ 1.5mg / L, E2 ≤ 5.0mg / L.
