Research paper thumbnail of Hardness and contact angle of thermo-treated poplar plywood for bio-building

Poplar plywood, with a national production of around 270,000 m 3 in 2017, is a key product for the Italian wood sector, and currently is destined for several applications as component for furniture and motorhomes. Previous research has shown that thermal treatment can be effectively applied to poplar plywood in order to make it suitable to the requirements of new end-uses. The present study aims to widen the knowledge of the effects of thermal treatment on poplar plywood. With this purpose, 7-layered, 12-mm thick plywood bonded with urea-melamine-formaldehyde (UMF) resin was thermally treated for 2 h at 170, 190 and 210 °C through the Termovuoto ® process. The treatment aimed to improve the dimensional stability and durability against fungal decay. The process was set at lower temperature and shorter time than those of many thermal treatments commonly used in practice in order to limit the reduction in mechanical properties and to maintain an adequate bonding quality. The above properties were already verified by previous research, whereas in this study Brinell hardness and contact angle of treated panels were investigated as relevant for several end-uses that can be prospected in building and in outdoor environments. Brinell hardness decreased from 10.8 to 8.3 N mm-2 and contact angle increased from 75.8° to 103.6°. Overall, treatment at 190 °C seems the most suitable to induce balanced modifications in the panels. From a technical point of view, these appear ready to enter the market, for instance for use in exterior claddings, partitions and outdoor flooring.

Il libro attraverso l'apporto di diverse competenze disciplinari (scienze forestali, tecnologia dell'architettura) indaga il tema della valorizzazione del legno nella prospettiva di filiera corta come materiale da costruzione in relazione ad una prospettiva di sviluppo sostenibile. Il testo analizza il patrimonio di esperienze e di esperienze progettuali sviluppate sia in ambito internazionale che nazionale attraverso l'individuazione di buone pratiche in questo settore (linee guida, studi di inquadramento) per la valorizzazione dell'uso delle risorse legnose con particolare riferimento al consolidamento e la diversifica...

The influence of some surface and edge coatings on MUF glued panels, made of veneers of the poplar clone 'I-214', has been evaluated against the attack of wood decay fungi, according to the test method provided by CEN/TC38, now ENV 12038. The residual bonding quality has also been verified (EN 314). All specimens showed a high level of biodegradation. The best protection system seems to be the combination of treating the surface and painting the edges of the panels, while the surface treatments alone were less effective. The article also points out that the test method used is not the most suitable for evaluating the biological durability of plywood, considering its real use in exterior conditions. poplar / plywood / fungal decay / biological durability / protective treatment Résumé-Résistance du contreplaqué de peuplier aux dégâts dus aux champignons : efficacité des traitements de protection en relation à la norme ENV 12038. Ce travail est une contribution à la connaissance du comportement du contreplaqué de peuplier face aux dégâts dûs aux champignons, en considérant son utilisation dans une exposition caractérisée par une forte humidité. L'influence de la protection sur la surface et sur le bord des panneaux (collés avec une résine MUF) réalisés avec des placages déroulés provenant du clone 'I-214', a été évaluée contre l'attaque biologique des basidiomycètes en suivant la méthode d'essai ENV 12038. La qualité du collage résiduelle a été aussi vérifiée (EN 314). Tous les échantillons ont subi une biodégradation élevée. Le meilleur système de protection semble être une combinaison entre le traitement de surface et la peinture des bords des panneaux, alors que le traitement de surface seul est peu efficace. L'article montre aussi que la méthode d'essai employée n'est pas vraiment utilisable pour évaluer la durabilité biologique du contreplaqué, en considération de son emploi dans des conditions extérieures.
