One、Veneer board
Veneer plywood is a special type of plywood that is manufactured by bonding together thin wood strips or hollow core panels, and covering both sides with one or more layers of plywood. The resulting product is then compressed under heat and pressure.
Veneer plywood offers excellent screw-holding capacity, high strength, and features such as stiffness, sound absorption, and thermal insulation. It also has a low moisture content, typically between 10% and 13%, making it easy to work with and suitable for a wide range of applications.
Plywood is more stable than solid wood, but it is susceptible to moisture. During construction, it should be avoided in kitchens and bathrooms.
Two. Multi-layer solid wood panels
Multi-layer solid wood panels are manufactured by hot pressing three or more layers of solid wood or thin wood panels with wood adhesive. Plywood is generally available in six specifications: 3mm, 5mm, 9mm, 12mm, 15mm, and 18mm.
Multi-layer solid wood boards have an environmental grade of E1, making them the most commonly used material for handcrafted furniture. Their characteristics include low shrinkage, high strength, and excellent workability.
Three. Which is better, plywood or multi-layer solid wood board?
Particleboard is a special type of plywood, and its production follows the principle of symmetry to prevent warping and deformation. By overcoming the inherent heterogeneity of natural wood, particleboard achieves uniform properties and stable shape, making it a suitable alternative to solid wood. Although particleboard also contains free formaldehyde, its use of adhesives is minimal, resulting in superior environmental performance compared to fiberboard and particleboard. It is a high-quality flooring material.
Engineered plywood with alternating grain patterns exhibits minimal differences in physical and mechanical properties in the longitudinal and transverse directions, resulting in high structural strength, good load-bearing capacity, excellent moisture resistance, and minimal deformation. These advantages surpass those of particleboard. However, oriented strand board (OSB) offers advantages such as lower formaldehyde content, reduced material consumption, lighter weight, superior vertical load-bearing capacity, lower investment, and lower cost.
