【摘要】 用加压浸渍试验方法分别研究了压力、时间和染料溶液质量浓度对速生杉木液体渗透性的影响。结果表明 :①在加压浸渍试验的条件下 ,速生杉木的液体渗透性比之常压法有很大的提高。②外界压力和加压时间对速生杉木的液体渗透性有显著的影响。在一定的外界压力和加压时间范围内 ,速生杉木的液体渗透性随外界压力的增高和加压时间的延长而加大 ,其理想取值为外界压力 0 3～ 0 4MPa ,加压时间 60～ 90min。③染料溶液质量浓度对速生杉木的液体渗透性影响极小。考虑生产实践的要求 ,染料溶液质量浓度以 5～ 1 0g·L-1为宜。图 2表 1参 6更多还原

【Abstract】 Under pressure treatment conditions the liquid penetrability in fast growing Chinese fir and factors affecting on it were studied.Through a series of quantitative and qualitative analysis,the result showed that exterior pressure and pressing time had more effect on penetrability,but dyestuff solution content had less effect.The optimum was as follows:steeping time of 60～90 min,exterior pressure of 0 3～0 4 MPa and dyestuff solution consistence of 5～10 g·L -1.更多还原
