What is the purpose of the Hull cell test when using galvanizing brighteners? It plays an important role throughout almost the entire galvanizing production process, whether it is testing additive performance before use or troubleshooting galvanizing faults.
The role of the Hull cell test
When the Hull cell was first invented, electroplaters used it for testing and it served two main purposes: the first one is to obtain current density range of qualified plating layer, and the second one is the factors affecting current density range. Later, with the wide application of Hull cell, electroplaters also carry out deep research on it, resulting in a great expansion of the role of Hull cell test, through the Hull cell test almost all the plating process parameters and plating solution performance parameters can be confirmed.
This is manifested in the effects of the main salt, auxiliary salt, pH, temperature, agitation, impurities, and the role of brighteners, etc..Many experienced field plating technicians and operators can utilize the Hull cell test to troubleshoot plating solution problems that arise.There are also plating developers and manufacturers who use Hull cell test pieces to illustrate the performance of their products and provide product samples for users to do Hull cell tests to verify the performance of their products. Before purchasing Bigely's galvanizing brighteners and other products, many customers will use the samples provided by us to do the Hull cell tests to check the performance of the product's plating solution and coating.
