摘要
本技术在国内外首次提出 ,硝酸—硝酸铁型印制板退锡剂的循环再生使用新概念 ,实现了退锡废液的零排放。由废退锡液处理所得到的再生型退锡剂的性能与新开缸退锡剂完全一致。这种退锡剂除了成本要低 60 %外 ,还可因再生过程回收到重金属而产生可观的利润。
It's the first time to give the new concept in domestic and overseas that nitric acid-ferric nitrated tin-lead stripper can be recycled and reused without waste.The specifications of the recycled stripper are as the same as the new one.Apart from the 60 % lower costing,this kind of stripper can give you an extra profit because of heavy metals are gained in the recycle process.
