简介:以废弃锡合金的回收利用为目标,计算绘制了Sn-Pb、Sn-Sb及Sn-Zn二元合金的气-液相平衡成分图。结果表明:Pb、Sb及Zn能够有效地与Sn分离。以此为指导,对不同成分的Sn-Pb合金、Sn-Pb-Sb合金、Sn-Pb-Sb-As合金、粗Pb合金以及Sn-Zn合金开展真空蒸馏工业化实验研究。实验结果表明:Sn-Pb合金在1323K条件下经真空蒸馏可获得含Pb>99%的粗Pb和含Pb≤0.003%的Sn;Sn-Pb-Sb合金经一次真空蒸馏,可得到含Sn量>90%、含Pb量≤2%、含Sb量≤6%的粗Sn和含Sn≤2%的粗Pb;粗Sn经过真空蒸馏后,产品中Pb和Bi含量达到Sn锭GB/T728—2010中Sn99.99A级标准,超过50%的As和Sb得到脱除;Sn-Pb合金在1173K。体系压力20-30Pa条件下真空蒸馏8-10h,得到的产品Zn中含Sn<0.002%,Sn中含Zn约3%。
