燃煤电厂烟气经过湿法脱硫后，烟气的腐蚀性超过了原烟气的腐蚀性，湿烟气对烟囱内壁造成了严重的腐蚀。高分子涂料具有施工简单，工程造价低，适用烟囱范围广等特点，同时随着高分子性能的不断改进，防腐蚀效果突出，因而在烟囱防腐蚀中具有广泛的应用前景。本文综述了应用于湿烟囱防腐蚀领域的高分子涂料种类、主要性能及应用业绩情况，旨在为新旧湿烟囱保护措施的选择提供有益参考，还对高分子涂料在这一领域的发展前景做出了展望。
When wet desulphurization devices are installed in the coal-fired power plants, the flue gas becomes much more corrosive, and the chimney wall would be badly corroded by the wet flue gas. Polymer coatings have low price, wide application and are convenient to be constructed. At the same time, their properties have been greatly improved in the past years. With these advantages, polymer coatings show a bright future in the chimney anti corrosion field. This paper discusses the kinds, properties and application situation of polymer coatings in the chimney anti-corrosion field. It aims to offer a reference for the design and protection of wet chimneys. The prospect of polymer coatings in this field is also discussed.
