RIQUELME-VALDES, JUAN et al. FIBERBOARD MANUFACTURED WITHOUT RESIN USING THE FENTON REACTION. J. Chil. Chem. Soc. [online]. 2008, vol.53, n.4, pp. 1722-1725. ISSN 0717-9707.  doi: 10.4067/S0717-97072008000400019.

Resin-free fiberboards were manufactured using industrial fiber from Pinus radiata activated by an oxidative treatment using the Fenton reaction (H₂0₂/ Fe(II)). A multivariate analysis was used to study the effect of fiber moisture content (MC), press temperature (T), and the H₂0₂/Fe(II) ratio on the board internal bond strength (IB). Using response surface methodology, a set of máximum IB conditions was obtained. Validation of these conditions which included 25% MC, 170°C press temperature and a H₂0₂/Fe(II) relation of 25 produced an optimal board with an IB strength of 0.888 MPa. Without the addition of sizing agents or other additives, the dimensional stability properties were 16% of thickness swell and 40% of the water absorption of control boards.
