Pickling

WIM Acid Additives Pickle Cleaner, Faster Than Regular Inhibitors

WIM acid additives react with the hydrogen as it is formed when the acid attacks the soluble scale.

This hydrogen polarizes the pickling reaction and inhibits the rate of scale removal. Rather than try and smother the hydrogen WIM uses controlled depolarization to quickly remove the hydrogen. Once the scale is gone the depolarizers stop working and the WIM inhibitor takes over to protect the steel.

Faster scale removal helps the pickler choose the best way to operate.

Faster scale removal also means you can pickle colder and consume less energy, a spectacular way to add up savings. Faster scale removal means you can use a weaker acid or pickle with your acid longer than normal, acid recovery is more efficient, acid consumption improved. Faster scale removal means that the recovered acid is not as sluggish. Faster scale removal means you can pickle intelligently tailored to your wants and needs.

Pickling is complex

We realized that when pickling steel, you cannot rely on a particular acid, inhibitor or accelerator as the sole source of controlling efficiency while producing a clean, scale free surface. Pickling is too complex for such a simple choice. Inhibitors do inhibit the inherent corrosiveness of an acid. They are so effective that they retard scale removal while reducing acid consumption. Accelerators on the other hand improve the corrosive properties of a pickling acid and accelerate rates of scale removal.

WIM helps you control the pickling process

WIM solves that problem by controlling the accelerator so that it responds only to the oxides being removed. When there is a soluble oxide to be removed the WIM accelerator turns itself on. When that soluble oxide is removed the WIM accelerator turns itself off and lets the WIM inhibitor take over to provide the appropriate protection for the pickled surface. WIM controls the pickling reaction better because it lets the acid remove the soluble oxide unimpeded by the inhibitor, then steps aside to let the inhibitor protect the pickled surface.

It is this intelligent use of two opposing chemical reactions that permits you, the pickler, to gain better control over the pickling process and reap its benefits through lower energy use and reduced acid consumption. Tank life can be increased and the pickled surface shines brighter due to the improved acid reaction with the steel.
