色木径向、弦向、非标准向压缩木的吸水性

Water absorbing Capacity of Mono Maple's Radial, Tangential and Non standard Direction Compressed Wood

对色木径向、弦向、非标准向压缩木的吸水性测试结果表明 :不论哪个方向压缩 ,压缩木压缩方向上的膨胀率明显高于非压缩方向的膨胀率 ;压缩木压缩方向在 2 4h之内的吸水速度最快 ,之后趋于缓和 ;在浸水前 3d径向压缩木径向的膨胀率大于弦向压缩木弦向的膨胀率 ,3d之后情况相反 ;压缩木压缩方向的垂直方向上的膨胀率 ,弦向压缩最小 ,径向压缩最大 ,非标准向居中。

Water absorbing capacities of mono maple's radial, tangential and non standard direction compressed wood were tested, results are as follows. Swelling efficiency in compressed direction was obviously higher than that in non compressed direction whichever direction was chosen to be compressed. The absorbing water velocity of the compressed woods in compression direction within 24 hours was the highest, then come to be getting gentle. During the first three days of impregnating the compressed wood with water, the swelling efficiency in radial direction of radial compressed wood was higher than that in tangential direction of tangential compressed wood, contrary result however appeared after three days. Swelling efficiency in vertical direction of compressed direction was the smallest in tangential, the biggest in radial and middle in non standard direction compression.
