Study on the characterization of the plywood fire spread;

胶合板表面火蔓延特性研究

The results showed that enzyme concentration and pretreatment duration had a significant effect on the surface bonding strength of wheat straw.

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。

Based on test data and information concerned, a summary account is given of the characteristic and qualityrequirements of plywood sheathing for wood frame construction.

通过试验数据及有关资料,简述了轻型木结构用覆面胶合板的特点,并介绍了相关产品标准的质量和性能要求。
