Mat Compression Measurements During Low- Density Particleboard Manufacturing Piotr Boruszewski, Piotr Borysiuk, Mariusz Mami ń ski, and Joanna Czechowska Faculty of Wood Technology, Warsaw University of Life Sciences - SGGW, Nowoursynowska Str. 159, 02- 776 Warsaw, Poland This study regards the effect of technological aspects on mat compression during the manufacturing of low-density particleboards made of two low density species - i.e. poplar and pine. Using these materials, three-layer low-density particleboards (500 kg/m3) were prepared. Three series were manufactured: (1) neat pine, (2) poplar-pine (face layer and core layer, respectively) and (3) neat poplar boards. Measurements of real-time variations in mat core temperature, pressure, and mat thickness allowed for the analysis of the mat compaction. Selected mechanical properties (modulus of rupture, modulus of elasticity, and internal bonding) of the manufactured particleboards were determined. Raw material of lower density used for particleboard manufacturing required either prolonged pressing time or more intense heat transfer into the mat core. The highest strength values were
obtained for the poplar-pine particleboards. BioResources 11(3), 6909-6919. (Open Access) DOI: 10.15376/biores.11.3.6909-6919
The Paper Industry Technical Association (PITA) is an independent organisation which operates for the general benefit of its members – both individual and corporate – dedicated to promoting and improving the technical and scientific knowledge of those working in the UK pulp and paper industry. Formed in 1960, it serves the Industry, both manufacturers and suppliers, by providing a forum for members to meet and network; it organises visits, conferences and training seminars that cover all aspects of papermaking science. It also publishes the prestigious journal Paper Technology and the PITA Annual Review , both sent free to members, and a range of other technical publications which include conference proceedings and the acclaimed Essential Guide to Aqueous Coating .
