ABSTRACT

The  particleboards  are  the  most  consumed  in  the  world,  where  much  of  the  demand  is  associated  to  furniture sector. This study aims to assess the heat treatment effect on particleboard panels. The experiment consisted of four treatments and the control sample, evaluating temperatures of 160°C and 180°C for six and twelve minutes. Commercial particleboard panels were produced with particles of Eucalyptus sp.and urea-formaldehyde synthetic resin. Samples for physical testing (water absorption, and thickness swelling) and mechanical (static bending strength and screw withdrawal strength) were taken from these panels. For physical properties, the assessed heat treatments influenced significantly the water absorption of the panels after 24 hours of immersion. The treatment that utilized temperature of 180°C for six minutes provided the best performance. Concerning to the mechanical properties, the evaluated treatments had non-significantly influence in the panels strength.

RESUMO

Os  painéis  aglomerados  são  os  mais  consumidos  no  mundo,  sendo  que  grande  parte  da  demanda  destes  painéis está associada ao setor moveleiro. O presente estudo teve como objetivo avaliar o efeito do tratamento térmico  em  painéis  aglomerados.  O  experimento  consistiu  de  quatro  tratamentos  mais  a  testemunha,  avaliando as temperaturas de 160 e 180°C por períodos de seis e doze minutos. Foram utilizados painéis aglomerados comerciais produzidos com partículas de Eucalyptus sp. e, resina sintética ureia-formaldeído. Destes  painéis  foram  retiradas  amostras  para  os  ensaios  físicos  (absorção  de  água  e  inchamento  em  espessura)  e  mecânicos  (resistência  à flexão estática e resistência ao arrancamento de parafuso). Para as propriedades físicas, os tratamentos térmicos avaliados influenciaram significativamente a absorção de água  dos  painéis  após  24  horas  de  imersão.  O  tratamento  que  utilizou  a  temperatura  de  180°C  por  seis  minutos foi o que proporcionou o melhor desempenho. Já para as propriedades mecânicas, os tratamentos avaliados não influenciaram significativamente a resistência dos painéis.
