Dziurka D. , Mirski R. , Łęcka J. 2006. THE EFFECT OF PINE PARTICLE MOISTURE CONTENT ON PROPERTIES OF PARTICLEBOARDS RESINATED WITH PMDI, EJPAU 9(1), #16.
Available Online: http://www.ejpau.media.pl/volume9/issue1/abs-16.html

ABSTRACT

The effect of pine particle moisture content (within the 2÷25% range) on properties of particleboards resinated with PMDI was investigated in this study. The conducted investigations showed that along with an increase in particle moisture content (up to 15%) an improvement is observed in the mechanical properties of manufactured boards, i.e. modulus of rupture, modulus of elasticity and internal bond. No significant effect was found for particle moisture content on water resistance of boards, measured by their swelling in thickness after 24h and internal bond after the boiling test.

Key words: particleboard, PMDI resin, particle moisture.
