Abstract

The moisture sorption properties of wheatstraw fiberboard were examined as a function of humidity.The fiberboards were made from wheatstraw untreated and treated by xylanase.The moisture contents of these fiberboards were measured at different temperature and different relative humidities to obtain the sorption isotherm of wheatstraw fiberboard.The multistep sorption isotherm was modeled with the GAB model. The results showed that the moisture content of adsorption and desorption of fiberboard from xylanasetreated wheatstraw was lower than that from untreated wheatstraw at the same identical temperature and relative humidity.The sorption property of wheatstraw fiberboard was influenced by temperatures and relative humidity. The experimental data could be well modeled with the GAB mathematical equation.
