近年来,钢丝镀铜,特别是化学镀铜得到广泛应用。钢丝表面镀铜,不仅满足了钢丝拉制过程的润滑条件.提供成品钢丝光洁表面,而且有利于增强产品的导电性能,焊接性能,以及改善与橡胶的结合力等。各种产品的使用性能,往往与铜层厚度有密切 In recent years, copper wire plating, especially electroless copper plating has been widely used. Copper plating on the steel wire not only satisfies the lubrication conditions of the steel wire drawing process, but also provides the surface smoothness of the finished steel wire, and is conducive to enhancing the electrical conductivity, the welding performance and the adhesion with the rubber. The performance of a variety of products, often with copper layer thickness is close
