高分子材料用于我国大气环境严酷度比较的研究

摘要

Accurate evaluating and describing environmental severity is an important guarantee of material selection and service life improvement. At present, study on environment corrosion grade by standard metal is fully and mature, but study on environmental severity using polymer material is quite rare. So, it is a benefit attempts to quantitatively classifying the environmental severity by using polymer′s degradation model. The result showed that, the severity of Qionghai is close to Lasha, and all are about 1.2 times of Guangzhou.%在大气环境腐蚀性分类分级的研究中，利用高分子材料来评价大气环境严酷度的研究并不多见。因此，尝试了利用高分子材料的老化模型来定量评价大气环境的严酷度。结果表明，广州、琼海、拉萨3个自然暴晒试验点中，琼海和拉萨的严酷度接近，约为广州的1.2倍左右。
