树脂制车窗玻璃具有轻量化、防止破损等优点,但由于其系由有机系高分子材料制作,在列车运行环境中长年使用,会出现一定程度的老化趋势(如黄变),要按规定周期更换。介绍了铁道综合技术研究所瞄准提高树脂玻璃寿命以削减维修成本的目标,以黄变为基础,把握长期老化的特性,研究提高寿命的可能性概况与成果。论述了运用各种试样开展相关试验,调查各项初期特性及其特性变化的情况。
Resin-made window glass has the advantages of light weight, prevention of damage, etc. However, since it is made of organic polymer material and has been used for many years in a train operating environment, a certain degree of aging tendency (such as yellowing) The provisions of the cycle replacement. This paper introduces the goal of improving the service life of Plexiglas and reducing the maintenance cost by using the yellow technology as the foundation, grasping the characteristics of long-term aging, and studying the possibility of improving life expectancy. Discusses the use of a variety of samples to carry out the relevant tests to investigate the initial characteristics and changes in the characteristics of the situation.
