摘要
为提高废纸资源的利用率和附加值,用三种不同规格的废纸片与木材刨花混合制备木/纸复合刨花板,并分析纸片规格和添加量对板材物理力学性能的影响。结果表明,复合刨花板的力学强度随纸片尺寸的增加呈先升后降;随纸片添加量的增加而呈降低趋势;吸水厚度膨胀率则呈一直增加的趋势。
Three sizes(A,B and C)and 10%,20% and 30% of usage of waste newspapers were respectively mixed with wood particle by weight and formed as center layers of composite panels.Physical and mechanical properties of specimens of the panels were evaluated.Test results showed that modulus of rupture(MOR),modulus of elasticity(MOE)and internal bonding strength(IB)of the panels increased at beginning and then decreased with increase of waste newspaper sizes,and decreased with increase of waste newspaper usage.Thickness swelling rate(TS)of the panels increased with increase of both of wastepaper size and usage.
