Estimation and Environment-Deterioration Testing of Non-Metallic Liner Physically

摘要

Up to date, it is difficult to estimate durability of epoxy liner in service time because an estimation of the long term environment-deterioration with aging has not been processed. In the study, the estimation on epoxy liner is carried out by the physical test for 7 rounds. There are the elongation test and the crack bridging test in the part of physical tests. An elongation test is carried out with epoxy membrane and a crack bridging test is carried out with epoxy-coated specimen on mortar. The subjects of test and estimation are a containment quality system and a fibre-glass reinforced system. The materials of these subjects are ET5140, CL890, and EH2340. Ensuring the test data, properties of epoxy liner was estimated and the change of properties was predicted on epoxy liners.
