Particleboard belongs to one of artificial board made of wood or plant fiber raw materials, by crushing wood or plant fiber into particles or fragments, and then adding adhesive, pressed by high temperature and high pressure.
It is widely used in furniture manufacturing, architectural decoration, packaging and other fields, with low cost, strong plasticity, a wide range of raw materials and other characteristics
Many raw materials | Wood based waste like sawdust, wood chips, agricultural straw, High resource utilization |
Low production cost | Compare with Plywood, MDF, cost lower |
Easy processing | Easy to cut, carve, drill, laminate |
Good stability | Not easy to crack deformation, but poor moisture resistance (special treatment required) |
Environmental protection | Ordinary urea formaldehyde particle board contains formaldehyde, MDI rubber/soybean particle board can be aldehyde-free. |
- As Raw materials:
Wood particleboard (mainstream) : pine, poplar, eucalyptus and other wood processing leftovers, high strength.
Non-wood particleboard: made of agricultural residues such as rice husk, wheat straw and bagasse, more environmentally friendly but less strong
- As Density:
Low Density: 400-600kg/m3, for packing, deadening materials
Middel Density: 600-800kg/m3, for common furniture, decoration
High Density: 800-900kg/m3, for strength floor substrate, Load-bearing furniture
- As Adhesive:
Ordinary particle board (E2/E1 grade) : urea-formaldehyde resin (UF glue), low price, but containing formaldehyde.
Moisture-proof particleboard (E0 grade) : phenolic resin (PF glue), good water resistance.
Aldehyde-free particleboard (ENF grade) : MDI glue or soy glue, environmentally friendly but costly.
Particle board making machines
- Raw material treatment: wood or straw crushing, drying (moisture content control in 2%~5%).
- Sizing mix: Add adhesives (urea-formaldehyde resin, phenolic resin or MDI glue) and additives (water repellent, flame retardant).
- Paving molding: evenly paved into slabs (single or multi-layer structure).
- Hot press curing: high temperature (180~220℃) high pressure (20~30MPa) pressing, so that the adhesive curing.
- Post-treatment: cooling, sanding, cutting, some products will be veneer (melamine paper, wood veneer, etc.)
Furniture manufacturing: cabinets, wardrobes, desks, bed boards, etc. (usually covered with leather or spray paint)
Building decoration: floor substrate, partition panel, ceiling (moisture-proof type can be used for bathroom, kitchen)
Packaging industry: pallets, boxes (low cost, customizable)
Other uses: speaker box, exhibition props, DIY handmade materials, etc✔ Advantages
Low price: more economical than plywood and density board.
Environmental protection (part) : Waste wood and agricultural residues can be used to reduce resource waste.
Good processability: easy to cut, drilling, suitable for mass production
✖ Disadvantages
Moisture resistance: ordinary particleboard is easy to expand when exposed to water, and needs to be treated with moisture.
Poor grip force: the screw is easy to loosen, not suitable for frequent disassembly.
Formaldehyde problem: Ordinary urea-formaldehyde rubber plate may release formaldehyde, you need to choose E0 or ENF grade products
Look at the environmental protection level: E0 grade (≤0.05mg/m³) or ENF grade (≤0.025mg/m³) is preferred.
Check density: high-density board (≥750kg/m³) is more durable, and low-density board is easy to deform.
Observation surface: flat without empty drum, edge compact without loose particles.
Moisture-proof requirement: Select phenolic glue or MDI glue particleboard in humid environment.
Brand selection: Well-known brands more stable quality
