WHAT MAKES RODINE 213 THE BEST ACID INHIBITOR FOR OVER TWO DECADES

Rodine 213 has remained the most popular choice till date for Hydrochloric Acid pickling and plant cleaning.

Hydrochloric acid replaced Sulfuric acid as the pickling liquor since it pickles substantially faster with minimal base metal loss. The highly reactive chloride ion in the acid is the reason for high efficacy in the cleaning procedure. It is utilized for cleaning metals with alloy content of 6% or less. An acid inhibitor must be added to the pickling solution to keep the metal surface from dissolving or getting pitted. Such pickling acid inhibited liquor is called "Inhibited HCL" and is a mix of Hydrochloric acid solution in water (3% to 10%) and an acid corrosion inhibitor which in itself is a mix of natural and synthetic chemicals that adsorb on the metal surface during pickling.

Rodine 213 is a superior synthetic blend of keto-amine complex substitutes with non-ionic surfactants, alcohols and solvents particularly intended to restrain hydrochloric acid corrosion on metal surfaces during modern operations like surface cleaning and pickling. It is effective over an extensive variety of metal surfaces like Iron and Steel, copper and metal. Rodine 213 is a high foaming anti-corrosion additive with a high viability at dispersing oil and grease and is perfect for HCL based pickling liquor systems particularly before plating.

It guarantees metal surface protection during procedures including lime scale removal from kettle and pipework and from evaporating plants, removal of oxide residue from iron, steel, metal and copper. Rodine 213 is free from chlorinated hydrocarbons and heavy metals like arsenic and lead. It can be synergized with Hydrochloric acid pickling in stipulated dozes both by circulation method and by drench and flush operations. Rodine 213's exceptional quality and thermal stability makes it a perfect acid corrosion inhibitor for improvement of the pickling procedure by pre-warming the liquor bath with the inhibited acid system. It additionally works as an excellent acid fume suppressant.

Its key components can be summarized as follows:

•          Modifies metal surface to prevent corrosion

•          Easy to apply

•          Excellent wetting properties for better cleaning

•          Effective acid fume suppression

•          Saves Zinc during Plating

•          Reduces metal loss

•          Enhances quality of pickling acid bath, and decreases acid consumption

Rodine 213 has boundless modern applications in enterprises like Iron and Steel, Power Station, Heavy Engineering Industries, Petrochemical and Refineries, Sugar Processing Industry, Cement, Glass and Ceramic Industries to name a few.

RODINE 213 Acid inhibitor for Hydrochloric Acid - ChemEqual

Most metal hot working processes tend to leave a discoloring oxide layer or scale on the surface. Deposition of inorganic impurities, stains, rust and scales from ferrous, cuprous, aluminium and precious metal mostly as oxides hinder with further processes like extrusion, rolling and galvanizing. In jewellery making, soldering and annealing processes leave metal oxide residue that prevent polishing of ornaments. Such impurities are cleaned with the help of diluted solution of acids. The method is called pickling and the workpiece is dipped in a vat of acid solution popularly called “Pickle Liquor”.

Hydrochloric acid replaced the commonly used Sulfuric acid as the pickling liquor because it pickles much faster with minimum base metal loss. The aggressive chloride ion in the acid is the key to high efficiency in the cleaning process. It is used for cleaning metals with an alloy content of 6% or less. An acid inhibitor must be added to the pickling solution to prevent the metal from dissolving or becoming pitted. Such a pickling acid solution is called “Inhibited HCL” and is a blend of Hydrochloric acid solution in water (3% to 10%) and an acid corrosion inhibitor which in itself is a blend of organic compounds that adsorb on the metal surface during pickling.

Rodine 213 is a premium organic blend of keto-amine complex substitutes with non-ionic surfactants, alcohol and solvents especially designed to inhibit attack of hydrochloric acid on metal surfaces during industrial operations like cleaning and pickling. It is effective over a wide range of metal surfaces like Iron & Steel, copper and brass. Rodine 213 is a high foaming formulation with a high efficacy at dispersing grease deposits and is ideal for HCL based pickling liquor solutions especially prior to plating.

It ensures metal surface protection during processes involving elimination of lime deposits from boiler and pipework and from evaporating plants, removal of oxide deposits from iron, steel, brass and copper. Rodine 213 is free from chlorinated hydrocarbons and heavy metals like arsenic and lead. It can be synergized with Hydrochloric acid pickling in stipulated concentrations both by circulation method and by soak and rinse method. Rodine 213’s exceptional strength and commendable heat stability makes it an ideal acid inhibitor during enhancement of the pickling process by pre-heating the equipments with the inhibited acid solution. It also acts as a strong acid fume suppressant.

Its key features can be summarized as follows:

Modifies metal surface to prevent corrosion

Easy to use

Excellent wetting properties for better cleaning

Effective fume suppression

Saves Zinc in galvanizing (Plating)

Reduces metal loss

Enriches strength of pickling acid bath, and reduces acid consumption

Rodine 213 available at ChemEqual has widespread industrial application in industries such as Iron & Steel, Power Station, Heavy Engineering Industries, Petrochemical & Refineries, Sugar Processing Industry, Cement, Glass & Ceramic Industries to name a few.
