| Résumé | The use of poplar wood as a raw material for making hardboards was investigated. Poplar chips were pulped by the Asplund process and formed into hardboards by the wet process. Strength of the hardboards made from poplar was lower than boards made from coniferous woods when no resin was used. The strength of poplar hardboards can be increased to an acceptable level by adding resin or starch to the refined stock. Without sizing agents the water sorption was the same for boards made from poplar and coniferous wood. It was not possible to size poplar hardboards well with was emulsion size to meet specifications for Class 1 standard board. When they were sized with 1% long-chain fatty acids 1% phenol-formaldehyde resin was added, the poplar boards were strong enough and water-resistant enough to meet all specifications for standard hardboard except for thickness expansion. |
