通过对粉末涂料体系和树脂的选择,以及脱气剂、硅烷偶联剂等助剂的添加,制得在热镀锌钢管表面具有优异附着力的粉末涂料产品,最终得到的“钢管+镀辞层+粉末涂层”的三层防护系统,进一步延长了钢管的使用寿命。

Though the selection of powder coating system,resin,degassing agent,and the addition of silane coupling agent and other additives,the powder coating products with excellent adhesion on the surface of hot-dip galvanized steel pipe were prepared.The obtained three-layer protection system of“steel pipe+galvanized layer+powder coating”can further extend the service life of the steel pipe.
