摘　　要：介绍了无溶剂聚氨酯涂层技术在一条DN2 200钢管顶管工程中的具体应用。实践表明,对于大口径钢管的内、外防腐,该涂料不仅具有良好的防腐效果,而且在工程难点及其重要部位的应用还具有较高的性价比。Because non-solvent corrosion resistance, compact coating, temperature, it is applied widely. The polyurethane has a lot of virtues, such as fast curing, excellent high strength, good abrasion resistance, good performance at low application of polyurethane coating technique in a jacking engineering of a DN2 200 water pipe was introduced. The practice shows that this coating has a good internal and external anti-corrosive effect on steel pipe with large caliber and a higher ratio of performance to price in the application at the difficult engineering sites and important locations.
