摘要:
为了改善黑木相思木材干燥质量,促进其合理高效利用,采用百度试验法对5年生和7年生黑木相思的木材的干燥特性展开研究,通过分析试件的初期开裂、内裂及截面变形等干燥缺陷,以期制定5年生和7年生黑木相思木材的干燥基准。结果表明:5年生和7年生黑木相思木材干燥特性基本一致。初期开裂等级为3级,内部开裂等级为1级,扭曲变形等级为3级,截面变形等级为2级,干燥速度等级为2级,综合等级为2级。木材的平均径向收缩率为4.48%,平均弦向收缩率为6.29%,平均差异干缩为1.40;黑木相思木材干燥初期干球温度为60 ℃,初期干湿球温度差为3 ℃,干燥末期温度为90 ℃,干燥时间约为8.5 d。
Abstract:
In order to improve the drying quality of Acacia melanoxylon wood and promote its rational and efficient utilization, the drying characteristics of the 5-, 7-year-old wood were studied by 100 ℃ test method. The drying criteria of 5-, 7-year-old wood were established by analyzing drying defects such as initial cracking, internal cracking and cross section deformation of specimens. The results showed that the drying characteristics of 5-, 7-year-old A. melanoxylon wood were basically the same, the initial cracking grade was 3, the internal cracking grade was 1, the distortion grade was 3, the cross section deformation grade was 2, the drying speed grade was 2, and the comprehensive grade was 2. The average radial shrinkage of wood was 4.48%, the average chord shrinkage was 6.29%, and the average differential dry shrinkage was 1.40. The dry bulb temperature at the initial stage of drying was 60 ℃, the difference between dry and wet bulb temperature at the initial stage was 3 ℃, the temperature at the end of drying was 90 ℃, and the drying time was about 8.5 d.
