摘要
研究采用3种浓度的NaOH对毛竹进行处理,测定浸渍处理前后毛竹的淀粉含量。将浸渍处理试样置于温度(30±2)℃,湿度95%±5%的恒定湿热环境中进行霉变实验,观察毛竹的霉变特性。研究结果表明:碱液浸渍处理能够降低毛竹淀粉含量,抑制霉菌出现时间,降低毛竹横切面、径切面、竹黄面霉变率。试样横切面、径切面、竹黄面上的霉变率随着淀粉含量的减少而减少。
Three levels of concentration of NaOH solution were used to treat bamboos and their mould performances were observed under lab condition.The starch contents of bamboo after alkali treatment and control samples were measured.Then the treated samples were put into a hydrothermal environment of temperature（30±2）℃,relative humidity 95%±5%.Moldy situations of bamboo were observed.The results suggested that by reducing starch content of bamboo,alkali treatment may delay the mould appearance time of bamboo and reduce the mould rate of cross section,longitudinal section,and inner bamboo surface.
