硅镁凝胶浸渍改性杉木在物理力学性能方面提升较佳，探究硅镁凝胶在杉木中的固着性能和机制，对后续研究与创新具有一定意义。以硅镁凝胶为改性药剂，人工林杉木为基材，浸渍干燥后制得改性杉木。通过FTIR和XPS分析杉木素材和改性杉木的化学成分和结合方式，并对硅镁凝胶在木材中的分布以及改性杉木的渗透性进行探讨。实验结果表明：硅镁凝胶浸渍改性杉木的物理力学性能得到明显改善，密度均达到0.5 g·cm-3以上，抗压强度和抗弯强度相比杉木素材分别提升了99.73%和58.48%,端面硬度从3 659 N提升到5 843 N,基本已达到中等木材的性能指标。EDS结果证明药剂在杉木细胞腔中填充状况良好，Si, O, Na...

The silica-magnesium gel impregnated modified Chinese fir has improved physical and mechanical properties. Exploring the fixing performance and mechanism of silica-magnesium gel in Chinese fir has significance for subsequent research and innovation. It is uses silica-magnesium gel as the modifying agent and fast-growing Chinese fir as the base material. Modified Chinese fir was prepared after dipping and drying. FTIR and XPS were used to analyze the chemical composition and combination of naturalChinese fir and modified Chinesefir and discussed...
