摘　　要：木材表面颜色的光变、褪色是影响木质产品商品价值的主要因素,选取18种市场上地板与家具装饰常用树种的木材试样,采用氙光加速老化的方法,通过蓝色羊毛标样与灰色样卡变色度的对比,评定其耐光色牢度等级,为今后木材耐光色牢度评定标准的制定提供依据。Photo-discoloration of wood surfaces not only causes the degradation of the wood properties,but also affects the commercial value when being used in decorative furniture or flooring products.Wood specimens of eighteen different species,which are usually used for furniture,were selected for an accelerated ageing test.After exposing the specimens to a xenon light for a certain amount of time,the specimens were taken out and compared with standard color samples.Colorfastness to light was rated in accordance with the grey scale.
