摘要
为改善木材的尺寸稳定性,采用二甲基二氯硅烷和聚硅氧烷分别对杉木进行改性处理,并测定处理材的疏水性能。结果表明,处理杉木的平衡含水率下降,杉木质量、与水的接触角和抗膨胀系数等均显著增加。
In order to improve the dimensional stability of Chinese fir, the authors used two formulae of dimethyldichlorosilane and polydimethylsiloxane solutions with n-hexane as the main solvent to treat the wood. The results indicated that the equilibrium moisture content of both treated samples decreased considerably. Surface water contact angle and antiswelling efficiency of treated samples increased.
