| Abstract: |
Testing of the oxidation resistance of geomembranes in the autoclave.The oxidation behavior of geomembranes, which are chemically stabilized by phenols and phosphites, with different additive concentrations was studied at high and low oxygen pressures by the autoclave test. It was found that the influence of chemical stabilization at an oxygen pressure of 50 bar is strongly suppressed and the influence of the stabilization regarding the lifetime cannot be determined. However, the influence of chemical stabilization on the oxidation behavior of geomembranes at lower oxygen pressures up to 5 bar can be detected and evaluated. The effective rate constant of the stabilizer depletion obeys a power law in oxygen pressure. |
