1) Decorative veneer veneer plywood is a man-made board made of natural wooden decorative veneer attached to plywood. Decorative veneer is a thin wood chip made of high-quality wood through sliced or peeled processing methods.
2) Features of decorative veneer plywood:
Decorative veneer veneer plywood is one of the most commonly used materials for interior decoration. Because the decorative veneer on the surface of the product is made of high-quality wood by slicing or rotary cutting, it has better decorative properties than plywood. The product is natural, simple, natural and noble, and it can create the best friendly and elegant living environment with people.
3) Types of decorative veneer veneer plywood:
Decorative veneer veneer plywood can be divided into single-sided veneer veneer plywood and double-sided veneer veneer plywood according to the decorative surface; according to the water resistance, it can be divided into type I decorative veneer veneer plywood and type II decorative veneer Veneered plywood and Class III decorative veneer veneer; according to the texture of the decorative veneer, it can be divided into radial decorative veneer veneer plywood and chord-direction decorative veneer veneer plywood. Common is single-sided decorative veneer veneer plywood. Commonly used wood species for decorative veneer are birch, ash, oak, shuiqinggang, elm, maple, walnut and so on.
4) Classification of decorative veneer veneer plywood:
my country’s decorative veneer veneer plywood standard stipulates that decorative veneer veneer plywood is divided into three grades: excellent, first-class and qualified. I would like to remind manufacturers and consumers that other grading forms do not meet my country’s decorative veneer veneer plywood standards. For example, some manufacturers have a logo level of “AAA”, which is a corporate behavior.
5) National standards for decorative veneer veneer performance requirements: my country’s current recommended standard GB/T 15104-2006 “Decorative veneer veneer wood-based panels”, most of the production of enterprises implement this standard. This standard specifies indicators for decorative veneer veneer plywood in terms of appearance quality, processing accuracy, and physical and mechanical properties. Its physical and mechanical performance indicators include: moisture content, surface bonding strength, immersion and peeling. GB 18580-2001 “Indoor Decoration Materials-Man-made Panels and Products of Formaldehyde Release Limits” also specifies the product’s formaldehyde emission limits.
① The national standard stipulates that the moisture content index of decorative veneer veneer is 6% to 14%.
②Surface bonding strength reflects the bonding strength between the decorative veneer layer and the plywood substrate. National standards stipulate that this index should be ≥50MPa, and the number of test pieces meeting the standard ≥80%. If this index is unqualified, it means that the glue quality of the decorative veneer and the base plywood is poor, which may cause the decorative veneer layer to open up and bulge during use.
③Dipping and peeling reflects the gluing performance of each layer of decorative veneer veneer plywood. The unqualified index indicates that the bonding quality of the board is poor, which may cause the glue to open during use.
④Limit of formaldehyde emission. This indicator is a mandatory national standard implemented by my country on January 1, 2002. This is a “birth certificate” for related products. Products that fail to meet this standard will not be allowed to be produced from January 1, 2002; this It is also a “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.
