| Abstract: | 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. |
