| 摘 要： | 以杨木单板及其染色单板为试材,使用氙光衰减仪进行辐射试验,分析这两种单板的光变色规律及影响因素,并进行耐光性能评价。结果表明:杨木单板的光变色是木材本身;染色杨木单板的光变色是染料和木材共同作用的结果,影响其光变色的主要因素是染料的品种和结构。因此,杨木单板的光变色小于染色杨木单板,而染色杨木单板中酸性蓝染色单板光变色最显著。

| Abstract: | With poplar veneer and dyed veneer as test pieces,a xenon attenuation instrument is used to conduct radiation tests in order to analyze light-induced discoloration rules and influential factors and to evaluate their light fastness.The results show that the light-induced degradation of poplar veneer is caused by the veneer itself and that the light-induced degradation of dyed veneer is the communal effect of dye and wood,with the main factors influencing the light-induced discoloration being the varieties an... |
