Saturated salt method determination of hysteresis of Pinus sylvestris L. wood for 35 ºC isotherms
Keywords:hysteresis, sorption, desorption, hysteresis coefficient, saturated salts, Pinus sylvestris
The saturated salts method was used in this study to quantify hysteresis in Pinus sylvestris L. wood, in an exercise that involved plotting the 35 ºC desorption and sorption isotherms. Nine salts were used, all of which establish stable and known relative humidity values when saturated in water The wood was kept at the relative humidity generated by each of these salts until the equilibrium moisture content (EMC) was reached, both in the water loss or desorption, and the water uptake or sorption processes. The Guggenheim method was used to fit the values obtained to the respective curves. Hysteresis was evaluated in terms of the hysteresis coefficient, for which a mean value of 0.87 was found.
