聚氨酯沥青涂料具有优良的保护效果,涂层坚硬耐磨,附着力强。1972年6月黄河水净化站澄清池使用聚氨酯沥青涂料防腐,1981年4月停产检修,认为该涂料防腐性能比较理想。深水部位最好,涂层无损坏,钢板无生锈;浅水部位次之,涂层面漆层局部有损坏,钢板局部有生锈;水位以上
Polyurethane asphalt coating has excellent protection effect, hard and wear-resistant coating, strong adhesion. In June 1972, the clarification pool of the Yellow River Water Purification Station used anti-corrosion polyurethane urethane paint. In April 1981, it was shut down for maintenance and it was considered that the anti-corrosion performance of the paint was satisfactory. The deep water part is best, the coating is not damaged, the steel plate has no rust; the shallow water part is followed, the coating topcoat layer is partially damaged, and the steel plate has local rust; above the water level
