摘要
借助CIE的L*a*b*标准色度学系统,研究了西南桦、云南松和云南铁杉装饰薄木在热处理过程中的材色变化特征。结果表明:随着处理温度提高和处理时间延长,装饰薄木的明度下降,处理前后色差增大;西南桦材色的热响应速度更快,变色主要发生于热处理开始的15 min内,云南松和云南铁杉对热处理的响应速度较慢,160℃以上的处理色差才显著增大,明度才有显著下降。
L＊a＊b＊ system（CIE） was used to investigate the color behavior of Betula alnoides,Pinus yunnanensis and Tsuga dumosa veneer during heat treatment.It was observed that,with the increase of treating temperature and duration,the lightness of the veneer decreased while the color difference between the untreated and the treated veneer increased.The response behavior varied among species.The discoloration of B.alnoides occurred within the first 15 minutes of heat treatment.For P.yunnanensis and T.dumosa,the discoloration did not occur until the temperature was above160℃.
