This paper examined the potential of reducing the hygroscopicity of pine wood treated with chitosan polymer. Chitosan is considered to be one of the most widely used materials having the major advantage of the existence of modifiable positions in its chemical structure (amino and hydroxyl groups). The Hailwood–Horrobin model was applied in order to determine the sorption isotherms. The analysis revealed that the treatment resulted in a reduction in the hygroscopicity, since the equilibrium moisture content of treated wood was reduced at all relative humidities, which was the case in both total polymolecular and monomolecular sorption. The application of chitosan compound was to reduce total sorption by 23.8%, polymolecular sorption by 20.6% and monomolecular sorption by 35.3% at saturation.

壳聚糖聚合物对木材水蒸气的吸附行为

本文研究了使用壳聚糖聚合物处理降低松木吸湿性的潜力。壳聚糖被认为是使用最广泛的材料之一，其主要优点是其化学结构（氨基和羟基）中存在可改变的位置。应用了Hailwood–Horrobin模型来确定吸附等温线。分析表明，该处理导​​致了吸湿性的降低，因为在所有相对湿度下，处理过的木材的平衡水分含量都降低了，这在总的多分子和单分子吸附中都是如此。壳聚糖化合物的应用是在饱和时将总吸附量降低23.8％，将多分子吸附量降低20.6％，将单分子吸附量降低35.3％。
