目前低温镀铁在全国推广并发展到有各种各样的工艺流程。但根据对工件镀面处理的方法不同,一般可划分为两大类:即有硫酸刻蚀的低温交直流及直流镀铁和无硫酸刻蚀的低温交直流及直流镀铁。有硫酸刻蚀的就是在处理工件镀面时,把工件挂在30%硫酸液中的阳极上,以铅板为阴极,通以定量定时的电流,以产生大量氧气来剥离工件镀面上的残余氧化 The current low-temperature plating iron in the country to promote and develop a wide range of process. However, according to the different methods of processing the workpiece plating, the general can be divided into two categories: that is, sulfuric acid etching of AC and DC AC and DC ferric and non-sulfuric acid etching DC AC and DC iron plating. Sulfuric acid is the etching of the workpiece surface treatment, the workpiece hanging in the 30% sulfuric acid in the anode, the lead plate for the cathode, through the quantitative timing of the current to produce a lot of oxygen to peel off the workpiece surface Residual oxidation
