摘要
采用棚下暴露、氙灯老化和荧光紫外灯老化这3种老化方法,研究聚苯乙烯在模拟户内环境下颜色随老化时间的变化。结果表明:聚苯乙烯颜色随老化时间的变化符合相关因数接近于1的线性回归方程;利用所获得的线性回归方程对聚苯乙烯的颜色变化进行预估,实测值包含在置信度为95%的预测区间之内。
Three aging tests,under roof,xenon lamp,fluorescent lamp were used to study the change of polystyrene color with aging times under simulated indoor environment.The results showed that the change of polystyrene color with aging times was conformed to linear regression equation,and its correlation coefficient near 1.According to the linear regression equation,one can predict the color-difference of polystyrene,and the observed data will be included in 95% confidence interval.
