Abstract

The surface roughness is primarily a function of the raw material properties, but other factors like type and amount of resin, press cycle, sanding and moisture content of the boards may also affect the roughness and other surface properties. In this study the effect of the equilibrium moisture content on medium density fiberboards (MDF) surfaces was evaluate using different raw materials in their surface layers as well as different binders. The statistical analysis confirmed that the relationship between equilibrium moisture content and average roughness are a complex function of interactions between many variables.
