Additives for hydrochloric – and sulfuric acid pickling baths
In the galvanizing process, steel is pickled in an acid tank after degreasing and before pre-fluxing. Acid pickling has the goal to remove the iron oxides or scales from the steel surface to expose a bare area on which a zinc layer can be place in subsequent process steps. To prevent corrosion during pickling a corrosion inhibitor is recommended as well as a fume suppressant (against nitric gases). AD Chemicals offers in this area:
- Corrosion inhibitor 04C is ad high performing and cost effective inhibitor for hydrochloric acid pickling bath additives. It is formulated to meet the needs of continuous hydrochloric picklers. It meets all the requirements of a qualitative pickling inhibitor: enables descaling, high-quality protection, can be rinsed, reduces acid consumption, metal and gage loss, fumes, is durable and results in a perfect uniform pickled surface.
- Additive SP is a foam blanket additive for hydrochloric acid batch pickling baths. It creates a uniform layer of foam on the surface of a steel pickling bath. It reduces heat loss and keeps corrosive hydrochloric fumes in the bath. For optimal performance to be used with Corrosion Inhibitor 04C.
