机械工程 耐光性 Treatment with photostability agents shows a obvious improvement on photostability of birch. The treatment methods of photostability agent have the most significant effect on improving photostability of bleached veneer. 耐光处理对漂白桦木的耐光性有明显的改善作用,处理方式对提高耐光性影响最大,漂洗阶段0.4%的苯骈三唑溶液浸泡得到的漂后单板耐光性能最佳。 光稳定性 Polyacetylene, poly(phenylene vinylene), and their derivatives are typically lacking a desired processability and longterm photostability. 如聚乙炔、聚亚苯基乙烯(PPV)及其衍生物,其缺点是缺乏良好的可加工性和持久的光稳定性。
