Surface roughness of uncoated particleboards and its relation with the raw material, adhesive and climatic conditions

The effect of raw material, adhesive and climatic conditions on the surface roughness and moisture content of uncoated particleboards was determined. Particleboards made with recycled particles in the surface layer had the roughest surfaces irrespective of the adhesive used. The relationship between equilibrium moisture content and roughness are a complex function of interactions between many variables.
