| 摘 要： | 对经木聚糖酶处理和未处理麦秸纤维制成的纤维板吸着特性进行了研究。测定了不同温度和相对湿度条件下，木聚糖酶处理对麦秸纤维板平衡含水率的影响，求得麦秸纤维板的吸着等温线，并且利用GAB模型对麦秸纤维板吸着等温线进行了拟合。结果表明：经过木聚糖酶改性处理麦秸纤维制成的纤维板，在相同环境温度和相对湿度条件下，吸湿和解吸平衡含水率均低于未处理麦秸纤维板；温度和相对湿度对麦秸纤维板的吸着特性有一定影响；采用GAB模型能较好地拟合试验数据，再现麦秸纤维板的吸着等温线。 |

| 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 xylan... |
