| 摘 要： | 为改善速生杉木木材的性质,试验中先后用硫酸铝和水玻璃等溶液对其进行处理,浸入木材的铝离子与硅酸根离子结合,在木材微纤丝间隙和管胞(或纤维)的胞腔中生成硫酸铝沉淀,从而使木材中填充了大量的无机物,得到杉木无机复合木材.无机复合木材的尺寸稳定性显著提高,在最优化工艺下,复合木材的抗收缩系数可达34.21,稳定系数在80%以上.同时,复合木材除抗冲击韧性略有下降外,其余如抗弯强度、抗弯弹性模量、顺纹抗压强度及硬度等主要力学性能指标均有明显提高.

| Abstract: | To improve the properties of fast growing Chinese fir,Aluminum Sulfate solution and water glass solution are used successively to treat it in the experiment.As a result,the aluminum ions that go into the wood react with silicate ion to produce aluminum sulfate precipitation in the wood microfiber and fiber tracheid which fills the wood with a large amount of inorganic matters and then inorganic composite of Chinese fir is obtained.The dimensional stability of inorganic wood composite is improved substantial... |
