【摘要】 研究了速生杨木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:随着纤维素酶和半纤维素酶用量的增加,杨木的表面自由能和胶合强度逐渐上升。在试验区间内,酶处理时间越长,杨木的胶合性能改善效果越明显。更多还原

【Abstract】 The influnce of enzyme treatment on poplar wood surface properties such as the surface wettabili- ty,chemical group and gluing strength is studied.The results show that the surface free energy and gluing strength of poplar increase with the dose of cellulase and hemicellulase rising.In the testing area the longer the treatment time is,the more obvious poplar wood gluing property improves.更多还原
