Umidade de equilíbrio de painéis OSB produzidos com inclusão laminar e com diferentes tipos de adesivos

Abstract: RESUMO:Neste trabalho, objetivou-se avaliar diferentes modelos estatísticos para a estimativa da umidade de equilíbrio de painéis OSB expostos a diferentes condições de temperatura e umidade relativa do ar, bem como avaliar a influência do adesivo e do reforço laminar na umidade de equilíbrio. Os painéis foram produzidos com três diferentes tipos de adesivos (fenol-formaldeído -FF, melamina-uréia-formaldeído -MUF, e fenol-melamina-uréia-formaldeído -PMUF) e, ainda, com e sem a inclusão laminar. A avaliação da … Show more

“…This did not occur in the present study, possibly due to the addition of paraffin emulsion in the amount of 1% with relation to the dry weight of the particles. The paraffin emulsion reduced the water absorption by sealing the particles (Cloutier 1998;Marra 1992;Mendes et al 2003Mendes et al , 2014. Concerning the 24-h swelling samples, the P2, P3, and P4 met the requirements of the EN 300 (2006) (17.1%, 20%, and 20.5%, respectively), as shown in Tables 4 and 6.…”

“…The measurement of the contact angle between the cellulose pulp surface and the drop of distilled water was performed on a Krüss goniometer, using the Advance software. The moisture absorption test followed the speci cations proposed by Mendes (Mendes 2014) with minor modi cations, before and after the plasma treatment. 0.25 g of sample was packed in aluminum crucibles for later heat treatment at 100°C for 24 hours.…”
