本发明内容是关于生产镀锡板的一般电镀方法和生产具有高耐蚀性的酸性电镀锡板的特殊方法。用于金属制罐工业中的绝大多数镀锡板都是用酸性镀锡溶液或碱性镀锡溶液生产的电镀锡板,很多人认为酸性电镀锡方法是一种既快又简单而且较为经济的方法。因此用酸性镀锡法生产的镀锡板的比例比用碱性镀锡法生产的要大得多。可是碱性镀锡板具有令人满意的特殊性能试验值(如酸渍滞后值,锡合金偶合值和铁溶值等)通常显示出高的耐蚀
The present invention relates to a general plating method for producing a tin plate and a special method for producing an acid tin plate having high corrosion resistance. The vast majority of tinplates used in the metal can industry are tinplates made from acidic tin baths or alkaline tinplates and many believe that the acidic tin electroplating process is a fast, simple and economical process Methods. Therefore, the proportion of tin plates produced by acid tinning is much greater than that produced by alkaline tinning. However, alkaline tin plate has a satisfactory special properties Test values (such as acid lag value, tin alloy coupling value and iron solubility, etc.) usually shows high corrosion resistance
