摘要
因一般高分子材料容易老化 ,尤其是在沙漠环境下 ,强烈的热光辐射、氧化更加速其老化过程。SH为新型高分子固化材料。本文通过SH固化沙体的室内老化试验 ,初步研究了SH的耐老化特征。结果表明 ,在间断或连续紫外线辐照下 ,SH耐老化性能优于同类其他固沙剂 。
The Polymer solidified material is prone to aging, especially in a desert environment where strong heat and ray radiations as well as oxidation may speed up the process of aging. This paper presents preliminary results of resistances to aging of SH, a new Polymer solidified material, by using an aging test of the SH-fixated sands. The results indicated that the resistance to aging of SH is better than other sand-fixing agents under periodic or continuous ultraviolet radiation. Therefore SH can be adopted in the fixation of sands in a desert environment.
