聚酯玻璃钢铁路信号器材1988年2月通过了铁道部部级技术鉴定。聚酯玻璃钢是近代材料科学兴起的一种新型材料。它具有多种优异的技术特性和良好的工艺性能,用它代替铁路常规材料:铸铁、铁板、钢板等,是一个创新,并显示出了广阔的发展前景。一、技术特性 1.良好的耐腐蚀性能聚酯玻璃钢具有良好的耐酸碱、耐有机溶剂、耐海水、盐雾和耐微生物作用的性能。其防腐性能优于钢材,不仅延长了使用寿命,而且大大降低了维修费
Polyester FRP railway signal equipment in February 1988 adopted the Ministry of Railways ministerial technical appraisal. Polyester fiberglass is a modern material science rise of a new type of material. It has a variety of excellent technical characteristics and good process performance, use it instead of conventional railway materials: cast iron, iron, steel, etc., is an innovation and shows a broad development prospects. First, the technical characteristics 1. Good corrosion resistance Polyester fiberglass has good acid and alkali resistance, organic solvents, seawater, salt spray and the role of micro-organisms. Its anti-corrosion properties better than steel, not only to extend the service life, but also greatly reduce maintenance costs
