简介：我们使用了联合代理人改进在小麦稻草粒子和UF树脂之间的结合的能力的silane，并且调查了表面性质(wettability和表面粗糙)和用与由联合代理人内容和稻草/白杨木头粒子比率的silane影响了的白杨木头相结合的结合UF的小麦稻草(TriticumaestivumL.)做的particleboard的坚硬。我们在0，5%和10%的三个层次在稻草的四不同比率生产了一个分层的particleboard面板到白杨木头粒子(0%，15%，30%和45%小麦稻草)和silane联合代理人内容。粗糙大小，平均粗糙(R),平均数peak-to-valley高度(Rz),和根平均数平方粗糙(Rq)被使用跟踪技术的一支好尖笔在unsanded样品上测量。我们由使用连接到一个数字照相机和计算机系统的角度计获得了接触角度大小。包含白杨粒子的更大的数量的板与控制样品相比有优异坚硬并且有更低的wettability。与有的silane的更高的数量做的面板降低R<潜水艇class=“a-plus-plus”>q值。
