摘要

采用统计学方法，综合分析木材压缩变形永久固定（定型）过程中热处理介质组成及其压力对木材颜色的影响，为处理过程中木材颜色变化控制提供依据。以蒸汽、空气、氮气，以及蒸汽与空气、蒸汽与

氮气的混合气体为热处理介质，在气体压力分别为0.1、0.3和0.5 MPa的环境中，对表层压缩毛白杨（

Populus tomentosa

）木材进行180 ℃、2 h的压缩变形固定处理，测定木材的颜色参数、质量损失率（mass loss，ML）和平衡含水率（equilibrium moisture content，EMC）。结果表明，介质种类和压力对毛白杨木材颜色有显著影响。随着压力的增加，处理材的

降低，

值增大，颜色向红棕色转变。以空气为介质时，随着压力的增加，处理材的△

显著增大；以蒸汽为介质时，压力增大至0.5 MPa时才对处理材△

产生显著影响；以氮气为介质时，压力的增加对处理材△

无显著影响。因子分析结果表明，处理材△

、△

和△

三者间，△

和△

间，以及ML和EMC间，均存在相关关系。基于颜色差值的聚类分析结果，在0.5 MPa压力下蒸汽介质处理材的△

和△

最大，分别为22.71和23.09，单独聚为一类；蒸汽介质中混入1/3或1/2的空气或氮气后，处理材的△

和△

均可降低50%以上，而且在聚为三类的情况下出现在同1个集群，在聚为四类的情况下又可以分为含有空气的介质处理和蒸汽与氮气混合介质处理2个集群。调控气体压力、以及蒸汽与空气或氮气的混合比，可以减少处理木材的色差，实现木材颜色的调控。

Abstract

Effects of heating media composition and its pressure on color changes in wood during permanent compression deformation were analyzed using statistical methods. The heating media

including steam only

air only

nitrogen (N

) only

and the mixture of either steam combining with air or steam combining with N

were used to treat the compressed poplar (

Populus tomentosa

) wood for permanent setting at 180 ℃ for 2 hours at various pressures of 0.1 MPa

0.3 MPa

and 0.5 MPa. The variables that represented wood color

mass loss

and equilibrium moisture content (EMC) were measured. The results showed that the medium composition and pressure had significant impact on wood color changes. When

decreased and

increased consistently with the increasing pressures

wood surface color turned to red brown. When air only was used as the medium

△

increased signif

icantly with the increasing pressure. When steam only was used as the medium

a pressure of 0.5 MPa had a significant impact on △

. When N

only was used as the medium

the increasing pressure had no significant effect on △

. The results of factorial analysis indicated that a certain relationship existed among the △

△

and △

between the △

and △

and between the mass loss rate and EMC. Based on color changes

the clustering analysis results showed that the largest absolute values of △

and △

were 22.71 and 23.09 at 0.5 MPa respectively. Either 1/3 or 1/2 of air or N

was added into the steam medium

△

and △

decreased more than 50%. Moreover

if the data was classified into 3 clusters

the similarity was shared among the clusters. If it was classified into 4 clusters

it could be further divided into 2 clusters: one was the treatment with air only and the mixed medium of steam and air

the other one was the treatment with a mixed medium of steam and N

. Through regulating the pressures and the mixing ratios of steam to air or N

the color of the pressured wood can be controlled.
