The effects of hindered amine light stabilizers (HALS), antioxidants on the radiation induced discoloration of polypropylene (PP) and polyethylene (PE) are studied.
结果表明五甲基HALS比相应的四甲基HALS更能有效地阻止聚烯烃的辐射致色。
The HALS system provided the UH-60 pilots with continuous 3d real-time radar imagery of the landing zone throughout the approach, hover, and landing in complete brownout.
在灯火管制情况下，在整个接近、盘旋和着陆过程中，HALS系统可以向UH - 60飞行员提供着陆区的连续三维实时雷达图像。
HALS are experimentally used in PVC films in this study. It is shown that thermostabilization and photostabilization functions of HALS are similar to those of benzophenone in PVC.
将受阻胺光稳定剂试用于PVC薄膜，结果表明，该光稳定剂用于PVC中，其光、热稳定效果与二苯甲酮类紫外光稳定剂相近。
It is also found that polymeric HALS is more effective in preventing PE from radiation-induced discoloration than corresponding monomeric HALS when radiation dose is higher than 200kGy.
并且发现，在相同的辐照剂量下，添加聚合物型HALS的PE的黄度比添加相应的单体型HALS的PE的黄度低一些。
