FIBERBOARD MANUFACTURED WITHOUT RESIN USING THE FENTON REACTION
Resin-free fiberboards were manufactured using industrial fiber from Pinus radiata activated by an oxidative treatment using the Fenton reaction (H(2)0(2)/ Fe(II)). A multivariate analysis was used to study the effect of fiber moisture content (MC), press temperature (T), and the H(2)0(2)/Fe(II) rat...

| Sumario: | Resin-free fiberboards were manufactured using industrial fiber from Pinus radiata activated by an oxidative treatment using the Fenton reaction (H(2)0(2)/ Fe(II)). A multivariate analysis was used to study the effect of fiber moisture content (MC), press temperature (T), and the H(2)0(2)/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 H(2)0(2)/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. |
