镀铜

1.With regards to the surface treatment, our crafts include nigrescence, phosphorization, zinc plating, dacromet, nickel plating and copper plating.

面处理有发黑、磷化、机械镀锌、达克罗、镀镍、镀铜等工艺。

2.Used AgNO3 Standard solution to measure the content of mercapto heterogeneous ring compound and thioureido derivative in acid coppering gloss agent continuously by potentiometric titration.

以硝酸银标准溶液，采用电位滴定法，连续测定酸性镀铜光充剂中巯基杂环化合物和硫脲衍生物含量。

3.The product has red dumet wire, pale (golden yellow) dumet wire, white dumet wire, no B dumen wire and luminous (is moisture-proof) dumet wire etc.

先面镀铜（或铜）技术使面状态呈均匀砖红色或黄色等。产品有红、淡（金黄）色、白、无硼和光亮（防潮型）等。

4.Cu-Sn alloy coating with different Sn content can be replacement plating out on iron and steel surface in a solution comprising of copper sulfate, stanous sulfate, complexant and stabilization agent.

铁件在由硫酸铜、硫酸亚锡、络合剂、稳定剂等组成溶液中,可以置换镀覆不同锡质量分数铜- 锡合金镀层,其工艺可替代氰化物预镀铜,消除氰化物污染,是实现电镀清洁生产措施之一。
