摘要
对薄板镀锡及储存过程中镀锡层表面产生的黑灰进行了研究。通过扫描电镜（ＳＥＭ）和能谱分析的观察与研究发现，黑灰的主要成分是锡的氧化物ＳｎＯ和ＳｎＯ２，导致黑灰产生的最有害的杂质是Ｆｅ２＋和锡泥。制定了一种“转移—明差”法用以表征黑灰程度。明度值测试表明，相对误差很小，可定量表征黑灰程度。
The harmful black granulas, which scatter on the surface of tin plated steel, formed during plating and storing, were investigated by SEM and EPMA. A new method named 'Brightness Difference Method' has been applied to characterize the degree of smudginess. The experiment showed that the main components of black smudge were SnO and SnO2. The effects of Fe2+ and tin sludge on the degree of smudginess were discussed.
