利用红外光谱分析法对影响工业相色管褪色的主要因素进行了探究。研究发现, 高温低湿的环境对相色管褪色老化影响最大; 紫外光的照射会导致相色管固化程度提高从而出现明显的老化现象; 过酸过碱的环境也会对相色管内部分子结构造成一定影响。本文结论从相色管基团变化的角度揭示了相色管老化的成因, 为日后进一步研究相色管抗老化防褪色机制提供了可行方向。

Various influential factors in the fading of the power accessory were investigated by the infrared spectroscopy in this study. The most important factor for the fading and aging of the power accessories is a high temperature and low humidity environment. In addition, UV radiation can lead to the increase of the degree of cure of the power accessories, significantly resulting in increasing its aging. Last but not least, strong acid or strong alkali environment will greatly affect the molecular structure of power accessories which could be greatly affected under the strong acid or strong alkali environments. These results not only reveal the reason of the aging of the power accessories, but also provide the feasible paths to the anti-aging and fade-proof of the power accessories.
