THE EFFECT OF VARIABLE ENVIRONMENTAL CONDITIONS ON DIMENSIONAL CHANGES IN THIN WOOD-BASED MATERIALS PART II. DESORPTION CHANGES
Journal Title: ELECTRONIC JOURNAL OF POLISH AGRICULTURAL UNIVERSITIES - Year 2010, Vol 13, Issue 3
Abstract
The study comprised an analysis of dimensional changes in thin wood-based boards caused by cyclical changes in relativehumidity at constant ambient temperature. Analyses were conducted on MDF, HDF, PB and OSB. As a result of these investigations it was found that final relative dimensional changes are significan tly dependent on changes in dimensions occurring at individual stages of conditioning, with the first ad sorption changes being most important. The lowest relative change in length determined in relation to the initial length was found for MDF board, while that in thickness – for HDF board.
