本文收集和编译了对耐酸腐蚀性较好的E-CR玻璃纤维及其层压板和压力管的耐腐蚀性研究的结果：ECR玻璃纤维与E玻璃相比在酸性介质中的耐蚀性能更好，能提高污水管道玻璃钢层的耐腐蚀性能，降低管壁厚度，能使聚酯玻璃钢在高腐蚀环境中得到应用。 Corrosion resistance of E-CR glass fibers with good acid corrosion resistance and their laminates and pressure tubes was collected and compiled in this paper. The corrosion resistance of ECR ​​glass fibers in acidic media is better than that of E glass , Can improve the corrosion resistance of the fiberglass layer of the sewage pipe, reduce the thickness of the pipe wall, and enable the polyester glass fiber reinforced plastic to be used in a highly corrosive environment.
