|Description: ||This work aimed to verify the efficiency of Nelson’s equation to estimate equilibrium moisture content of this material and provide a model for determination of moisture content of panels based on air relative moisture content, as well as to evaluate the effect of some processing variables on the equilibrium moisture content of OSB (Oriented Strand Board) panels. The 25 x 25 mm samples were put in an acclimation room where they were kept at 30°C and had their mass determined after stabilization at the relative air moisture contents of 40, 50, 60, 70, 80 and 90%. By the results obtained it was possible to conclude that: Nelson’s equation tended to underestimate moisture values of the panel; the polynomial model adjusted based on the relative moisture of the air presented great potential to be used; although different behavior may be observed for the isotherms of treatments, there was no significant effect of the variables panel density, wood basic density, mat type and pressure temperature on mean equilibrium moisture content in desorption 1, adsorption and desorption 2. |
