自硫化衬胶老化性能检测及状态评估

Aging Test and State Assessment of the Self-Vulcanized Rubber Lining

某核电站冷凝器水室衬胶已服役12年,本文通过收集和整理冷凝器水室衬胶自服役至今的目视检查、硬度、厚度等历史检查数据,检测水室衬胶老化性能,包含硬度、厚度、拉伸强度、拉断伸长率、粘合强度、耐磨性等指标,对水室衬胶进行老化状态评估和剩余寿命预测。

The condenser rubber lining aging is unavoidable during the service of the nuclear power plant.The paper is a collection of the visual check,Shore hardness,thickness data of the condenser Selfvulcanized rubber lining in 12 years,aging test the rubber lining,including the tensile strength elongation,tearing strength,adhesive strength,wear resistance,and provides a method of the Self-vulcanized rubber lining state assessment and residual life predication.
