Water Adsorption of Particleboard and Flakeboard

Benedito R. Vital, James B. Wilson


The amount of water adsorption (WA) determines the dimensional stability of particleboard and flakeboard. Regression models showed that WA is a function of relative humidity, resin type, and board specific gravity, as well as the thickness and slenderness ratio of the wood furnish. Those factors explained 95% of all variation in WA.
