钢铁构件长期暴露在大气中,会受到腐蚀介质的侵入而锈蚀,全世界每年大约有8～10%的钢材因腐蚀而损失掉。多年来,采用了各种方法以解决腐蚀问题。而在所有钢材防蚀方法中,热镀锌工艺是较经济的。其工艺简单、镀层美观,防腐蚀性能好,一直在国内外广为采用。
Steel components exposed to the atmosphere for a long time, will be corrosive media intrusion and corrosion, the world each year about 8 to 10% of the steel loss due to corrosion. Over the years, various methods have been adopted to solve the problem of corrosion. In all steel corrosion methods, hot-dip galvanizing process is more economical. The process is simple, beautiful coating, anti-corrosion performance, has been widely used at home and abroad.
