One. Characteristics of engineered wood products
1、Large surface area, excellent structure, and easy to apply.
2、Low expansion and contraction rate, stable dimensions, and a more uniform texture compared to timber, resulting in reduced deformation and cracking.
3. Plywood and various chips, which are used as raw materials for composite panels, are easily impregnated, making them suitable for various functional treatments.
4、Suitable for a wide range of thicknesses and densities.
5、Excellent bending and shaping performance.
Two. Applications of Engineered Wood Products
Engineered wood products, including plywood, particleboard, and fiberboard, comprise three main categories with hundreds of derivative and processed products. The following outlines some common applications of these engineered wood materials:
1、Plywood is a commonly used material for furniture, one of the three main types of composite wood panels, and can also be used for materials in aircraft, ships, trains, automobiles, buildings, and packaging boxes.
2、Thin plywood is widely used in furniture manufacturing, sewing machine tables, vehicle cabins, ships, and in the construction industry.
3、Honeycomb panels are commonly used for exterior cladding, interior decoration, advertising boards, marine construction, aerospace manufacturing, interior partitions, and display stands for commercial vehicles and containers. They are also used as a supply material for furniture.
4、Particleboard is widely used in domestic furniture, interior design, musical instruments, and packaging.
5、Intumescent boards are primarily used for furniture and general construction applications.
6、Aluminum composite panels are widely used for exterior walls of buildings, curtain wall panels, renovation and refurbishment of existing buildings, interior wall and ceiling decoration, advertising signs, display stands, and air purification projects.
7、Foam boards can be used for sound insulation and for inserting nails, especially suitable for structures with low strength and low load-bearing capacity.
8、Particleboard is commonly used as a substrate for veneers, furniture, ceiling panels, shelves, flooring materials, cabinets, partition walls, and stair treads.
Three. What are the advantages of engineered wood?
Engineered wood products are manufactured by processing wood or other non-wood plant materials into various unit materials through mechanical processing, followed by bonding with or without adhesives and other additives to form boards or molded products.
Engineered wood products increase the utilization of solid wood raw materials, reducing the consumption of solid wood resources, thereby contributing to the protection of forest resources and the environment.
However, the raw materials used in the production of engineered wood panels, such as urea-formaldehyde resins, still primarily consist of urea-formaldehyde resins. These resins and their products will inevitably release formaldehyde over time. This is due to both the fact that urea-formaldehyde resins contain a large amount of free formaldehyde during synthesis due to incomplete reactions, and the fact that urea-formaldehyde resins continuously degrade over time, releasing formaldehyde.
Therefore, when selecting engineered wood products, it is essential to choose products manufactured by reputable or large-scale engineered wood manufacturers. These products have formaldehyde emission levels within the specified range, and, when used correctly, pose minimal risk to human health.
