Particle Board QC Inspection Checklist : Part 3 Structure of PB

Particle Board QC Inspection Checklist : Part 3 Structure of PB

• Particles of mm dimensions
• Typically 3 layers – surface or
face material of fine particles
• Core material of coarser
material (larger chips)
• Density profile developed
during manufacture
– Improved properties in bending
– Harder surface

– Stiffness (bending)
– Density
– Surface hardness
– Screw holding
– Colour
– Surface “finish” (roughness)
– Moisture resistance
– Creep (long term deformation under a sustained load)
– VOC emissions
