Process and system for determination of layer thickness swell of wood composites

摘要

A process and system for obtaining a thickness swell measurement of a wood composite material sample. The process includes placing a measurement pattern on an edge of a wood composite material sample, the measurement pattern including layers having a thickness; measuring the thickness of at least one of the layers of the measurement pattern prior to exposing the wood composite material sample to a thickness swell-inducing condition; exposing the wood composite material sample to a thickness swell-inducing condition; and re-measuring the thickness of the at least one layer after exposing the wood composite material sample to a thickness swell-inducing condition to thereby obtain a thickness swell measurement for the wood composite material sample. Representative wood composite materials include medium density fiberboard (MDF), oriented strandboard (OSB) and particle board.
