金属腐蚀是个普遍而大量存在的问题,据有关资料统计:全世界每年金属腐蚀损失约为全年总产量的20%,每年就约有一亿多吨金属因腐蚀而报废。腐蚀引起的主要损失还不仅仅是金属本身,而在更大程度上给生产和使用带来了严重问题,甚至造成公害或人身事故。所以,在实际生产中对金属设备、管道、储罐等采取防腐措施有着极为重要的意义。(一)涂层防腐与带锈涂料多年来国内外对金属的防腐蚀问题都作了 Metal corrosion is a widespread and substantial problem. According to the statistics, the annual global metal corrosion loss is about 20% of the annual output. About 100 million tons of metal are scrapped due to corrosion every year. The main loss caused by corrosion is not only the metal itself, but also poses a serious problem for production and use to a large extent, causing even public nuisance or personal accident. Therefore, in the actual production of metal equipment, pipes, storage tanks and other anti-corrosion measures taken to have a very important significance.
