| 中文摘要 |
| 对我国大陆首次研制成功的高密度聚乙烯(HDPE)防渗材料在浸泡条件下的抗化学老化性能进行了系统测试,并与美国产品进行了比较。结果表明：在氢氧化钠溶液、16.7%硝酸、33.3%硝酸和三氯乙烯4种溶液中长期浸泡后,国产产品抗化学老化性能指数分别为0.775、2.8、3.15和3.15,已经全面达到国际水平。 |
| 英文摘要 |
| In this paper,the ageinhibiting property of Chinese-made high density polyethylene(HDPE)liners under exposure conditions had been studied systematically and compared with the products abroad.It is shown that the comprehensive index for chemical aging property under soak in NaOH aqueous solution,16.7% HNO3,33.3% HNO3 and trichloroethylene aqueous solution is 0.775 2.8 3.15 and 3.15 respectively,which has reached the international advanced standard. |
