The journey of the copper wire begins and ends with these systems. The pay-off unit precisely unwinds the raw copper wire, ensuring consistent tension as it enters the processing line. Conversely, the take-up system carefully spools the newly silver-plated wire. I prioritize systems that offer precise tension control and automatic spool changes to maximize uptime and minimize manual intervention.

Pre-treatment and Cleaning Units

Before silver plating, thorough cleaning is essential. I implement a multi-stage pre-treatment sequence to prepare the copper wire surface. This often includes:

1. Ultrasonic cleaning: I use LJ-28 neutral ultrasonic special cleaning agent (5% concentration, 40-50°C, 25kHz frequency).
2. Electrochemical degreasing: This involves cathode oil removal (3 min) followed by anode electrolysis reverse oil removal (30 sec) using FM-3 type weak alkaline electro degreasing powder (50g/L, 60-80°C, pH 10.0-11.5).
3. Hydrochloric acid activation: I soak the wire in 30% dilute hydrochloric acid solution at room temperature for 5-10 seconds. This removes oxide film and activates the surface.
4. Alkaline cooking: I perform this in a solution of 500-550g/L sodium hydroxide and 200-250g/L sodium nitrite for 20 minutes to loosen heat-treatment oxide scale.
5. Film removal: I soak the wire in 10% dilute sulfuric acid solution for 5-10 seconds at room temperature to remove any remaining oxide film. These steps ensure optimal adhesion for the silver layer.
