Electroplating plant in the face of nickel plating layer appears rough fault, often first from the nickel plating brightener to start troubleshooting, but in the actual production, the cause of roughness is a variety of reasons, such as hangers, sanding copper rods, treatment of the plating solution is not filtered thoroughly, and so on. This issue of the article we will analyze.
Powdering off of plating on hooks
In the use of nickel plating brightener, hooks on the hooks do not need to conductive parts of the insulating treatment is not cleaned in a timely manner, due to the hooks at the current density is particularly high, after repeated use will form a thick and loose plating, plating in the workpiece off, the corresponding part of the plating will be rough. This often happens in poorly managed plating plants.
Introduction of sand-washed copper rods
Common low-grade plating plant either conductive copper rod is very dirty, regardless of whether it affects the conductivity; either with sandpaper washing, the following and do not use something to catch the block, sand particles and dirt let it fall into the plating solution.
Failure to filter the plating solution thoroughly after treatment
When removing copper from bright nickel solution with sodium yellow hematite, the precipitate generated is difficult to filter clean. When adding powdered activated carbon to treat the plating solution (especially for zincate galvanizing solution with large viscosity), it is also difficult to filter thoroughly, and the residue becomes mechanical impurities.
