1 前言用作食品包装的镀锡板,近年来出现了高消耗状态。但是自七十年代末,世界锡资源日益紧张,锡价昂贵.使镀锡板生产成本提高例如1985年生产镀锡板用锡占原料成本费用的10％,1986～1987年上升为12—14％:据统计每年生产镀锡板耗锡量占世界总锡耗量的40％,因此减少镀锡板生产用锡无论对节约锡资源还是降低生产成本都是非常重要的。
1 Preface Used as a tin plate for food packaging, high consumption has occurred in recent years. However, since the late 1970s, the world’s tin resources have become increasingly strained and the price of tin has become so high that the cost of tinplate production has risen, for example, tin accounted for 10% of the cost of raw materials for tinplate production in 1985 and rose from 12-14 in 1986-1987 %: According to the statistics, the annual tin production accounts for 40% of the total tin consumption in the world. Therefore, reducing the tin production for tin plate is very important for saving the resources of tin and reducing the production cost.
