摘 要:
研究麦秸单元经过纤维素酶和半纤维素酶处理后的表面润湿性能、化学基团和胶合强度的变化。结果表明：在试验区间内，随着纤维素酶和半纤维素酶用量的增加，麦秸的表面胶合强度逐渐上升，UF树脂对麦秸表面接触角逐渐减小；酶处理时间的延长，有利于麦秸表面胶合强度的提高。[著者文摘]

Abstract:
A thin layer of wax and inorganic silica on wheat straw surfaces has been known to be one of the major barriers in utilizing wheat straw for profitable and marketable composites. Enzyme pretreatments with Trichoderma sp. and Aspergillus niger were used in this study to improve surface wetability and bonding performance. The results showed that enzyme concentration and pretreatment duration had a significant effect on the surface bonding strength of wheat straw. Generally, higher enzyme concentration and longer pretreatment will increase the surface bonding strength.[著者文摘]
