Acid Inhibitors

What Is An Acid Inhibitor?

Acid inhibitors are typically a modern dry powder inhibitor to thoroughly control the corrosive effects of all solid scale removers and some liquid scale removers. Acid inhibitors incorporate a unique filming agent which provides a protective coating to the metal guarding it against attack by the acid. At the same time, it has little or no effect in regard to impairing the efficiency of the acid action.

The type of inhibitor used is dependent on the type of material it will come into contact with and what it is designed to protect.

How Do Acid Inhibitors Work?

Our acid inhibitors are a combination of chemical agents including a dispersant and wetting agent which when applied to the acids listed below will reduce the severe acid attack on common metals to a negligible amount.

  • Sulfamic Acid
  • Tartaric Acid
  • Sodium Acid Sulfate
  • Citric Acid
  • Phosphoric acid
  • Sulfuric Acid
  • Oxalic Acid
  • Formic Acid

In a number of instances, inhibition from 99 1/2% to 100% has been achieved. Acid inhibitors are especially effective in protecting stainless steel, iron, bronze and admiralty metal. Unlike most inhibitors when used with granular grades of sulfamic acid, ours do not evolve acidic gases. These gases are very injurious if inhaled and are especially destructive to all electrical equipment and any material with which it comes in contact.

The inhibitors we offer, when added to sulfamic, sulfuric, phosphoric, oxalic and other acids, does not bring about this reaction so that it is much safer to use not only in regard to equipment, but also in regard to personnel handling the acid. However, it is recommended that all acid cleaning jobs be vented at all times. Careful consideration should be given to the selection of inhibitors in regard to this corrosive problem.

How Do We Suppress Corrosion?

O’B HIBIT, when in combination with sulfamic acid, does not increase to any great extent the dissolution rate of calcium carbonate scale like many other inhibitors. Our O’B HIBIT product has outperformed all other inhibitors, liquid or dry in tests on an equivalent basis of material added in pounds or percent by weight in the various acids listed in this bulletin. Savings of 35% to 50% on Inhibitor cost are possible using O’B Hibit. Check it out below!

If you’re in need of solutions for descaling, we have a range of products available to help. Our boiler descalers are an alkaline, aqueous blend of chelants, antifoam and a polymeric dispersant.  The chelating capability forms stable complex salts with cations.  Its ability to solubilize contaminants commonly found in boiler feedwater provides the greatest potential to maintain clean boiler heat transfer surfaces.  It prevents deposition even during periods of hardness leakage into the feedwater.  Products applied to systems where moderate deposition can be removed with an in-service chelant cleanup program.  Because of its chelating efficiency, boiler descaling agents can remove deposits formed when feedwater quality varies.
