The Acid Pickle Naturally Retards Production. Naxidic Puts You Back in Control
Naxidic acid will always out-perform its equivalent commercial grade acid.
All the different reactions that take place while pickling either weaken the acid or keep it from reacting with an oxide as efficiently as it can. As the acid weakens the pickling speed slows, although rejuvenated with fresh acid at some point a maximum acid addition is reached and the acid is disposed or recovered.
Common features of WIM® Acid Additives
Inhibitors Take Over Once Accelerators Have Done Their Job
When pickling with depolarizers you have an accelerating effect which turns on and off depending on presence of soluble oxides. Once the soluble oxides are removed the accelerator stops and the inhibitor takes over. This is not possible with systems which must rely solely on wetting agents.
Surfaces are 28% brighter due to the type of etch afforded by these accelerators. The cleaner pickled surface improves zinc deposition when hot dip or electro galvanizing.
Naxidic Acid and Fe
The Controlled Depolarizer in the acid neutralizes the inhibiting effect of Fe in the pickle.
Mill scale is not a simple iron oxide but one which is very complex and its timely removal depends on an acid which is ready to react with even the toughest combination of oxides. When conventional acid meets up with this situation immersion times may be increased to assure removal. The same oxide pickled with Naxidic Acid is more likely to be removed in its normal time.
Naxidic Acid Is Cost Effective
Naxidic acid, although more powerful than conventional acid is not an expensive upgrade. The money saved through improved acid consumption, energy conservation, and related labor savings well exceeds the slight surcharge for the Naxidic conversion.
