We all know that in the production process of plastic electroplating, the colloidal palladium adsorbed on the surface of plastic workpieces after palladium activation does not have catalytic activity. This is because its surroundings are surrounded by divalent tin ions, and the use of a gel remover can dissolve the divalent tin around palladium to expose it for treatment, so that palladium ions have catalytic activity. So what do we need to pay attention to when using glue removers?
Based on on-site experience and the characteristics of the product plastic electroplating adhesive, Bigley Technology analyzed that the adhesive can remove divalent tin ions adsorbed on the surface of the workpiece, exposing palladium ions. In this way, palladium metal acts as a catalyst in chemical nickel, promoting the deposition of the chemical nickel coating. So we need to pay attention to these four points when using glue removers:
1. During the production of gel breaking working solution, it is necessary to keep it clean, so a filter needs to be used for circulating filtration.
2. The release time of the workpiece during the release process should be appropriately matched with the activation time. If the release process is too short, it can cause poor electroplating of the workpiece, resulting in missed or overflow plating.
3. After a period of use, the adhesive release working fluid needs to be replaced or supplemented with new adhesive release agents to maintain a good adhesive release effect.
4. When replacing the adhesive release working fluid, it is necessary to reserve some old working fluid to ensure that the replaced adhesive release working fluid has a certain degree of activity and avoid affecting production efficiency.
So, we need to pay attention to the above four points in the production process of using plastic electroplating adhesive to reduce the occurrence of faults and improve production efficiency.
