1. Structure
Particleboard is a multi-layer structure, the surface is equivalent to MDF, and the density is good; The interior is a layer of wood chips that retains the fiber structure, and the layer structure is maintained by a specific process, which is close to the structure of natural solid wood panels.
2. Materials
MDF uses sawdust from the end of the forestry industry, and the material itself has no fiber structure at all. The particleboard uses lamellar wood chips that retain the fibrous structure and are machine-processed from untimber tree branches, rather than scraps.
3. Processing technology
Since the raw material of MDF is close to powder, the surface area of the same volume of material is much larger than that of lamellar wood chips used in particleboard. The adhesive consumed by board bonding and molding also far exceeds that of particleboard, which determines that the price, density (specific gravity) and formaldehyde content of MDF are higher than that of particleboard. It can be seen that the high price of MDF is due to high cost rather than performance.
Modern particleboard production processes use aerial atomization spray adhesives and layering processes, resulting in lower amounts of adhesives, more rational board structures, and therefore better quality.
4. Scope of application
Due to its uniform and delicate internal structure, MDF is widely used in the furniture industry to replace wood processing flower lines and carved products, such as European-style furniture door panels, hats, decorative columns, etc. Particleboard is widely used in the panel furniture industry because it is not easy to bend and deform, has a high strength-to-weight ratio, good nail holding force, and low formaldehyde content. Most of the international custom wardrobe brands and domestic enterprises choose particleboard.
