Environmental Compatibility of GRE Pipes in High-salty and CO2 Conditions
摘 要
采用DN100芳胺固化环氧玻璃钢管材为试验研究对象,在实验室条件下进行模拟高盐度、不同温度下CO2介质环境中的老化试验,并通过测定分析玻璃钢管材老化前后的环向拉伸断裂强度、巴氏硬度等性能的变化,研究了不同的盐度及温度对玻璃钢管材物理力学性能的影响。结果表明,温度、盐度等因素对于玻璃钢的拉伸强度和巴氏硬度影响不大。
Abstract
Glass Reinforced Epoxy (GRE) pipes (DN100) cured by aromatic amine were tested in the ageing environment containing salt of high concentration at different temperatures. By measuring the change of properties before and after ageing,iccluding hoop tensile fracture strength,Barcol hardness etc.,the effects of salt concentration and temperature on the mechanical properties of GRE pipes were studied. The results showed that factors such as temperature and salinity had little effect on the hoop tensile fracture strength and Barcol hardness of GRE.
