Resumen

WU, Qinglin; LEE, Ong N; CAI, Zhiyong  y  ZHOU, Dingguo. CREEP BEHAVIOR OF BORATE-TREATED STRANDBOARD: EFFECT OF ZINC BORATE RETENTION, WOOD SPECIES, AND LOAD LEVEL. Maderas, Cienc. tecnol. [online]. 2009, vol.11, n.1, pp.19-32. ISSN 0718-221X.  http://dx.doi.org/10.4067/S0718-221X2009000100002.

Creep performance of zinc borate-treated strandboard from southern pine (Pinus taeda L.) and red oak (Quercus falcata) was investigated at 250C temperature and 65% relative humidity. It was shown that the borate treatment had some significant effect on creep deflection of the test panels, and the effect varied with wood species. There was no significant effect of creep loading on residual bending properties of treated strandboard under the stress levels used. The four element spring-dashpot creep model fitted the creep data well. The predicted creep deflection for a 10-year loading duration under both 15% and 40% stress levels met the National Design Specification for Wood Construction despite of the noticeable borate treatment effect on creep. Future work is needed to study the creep behavior under combined mechanical and moisture loadings for treated structural panels.

Palabras clave : Rheological behavior; creep; chemical treatment; OSB; zinc borate.
