ACID CORROSION INHIBITOR

Rodine range of Acid Inhibitors

ACID CORROSION INHIBITOR - INTRODUCTION

Acid Corrosion Inhibitor stands out to be an effective and most used product for providing complete protection to base metals against the corrosive attack of most acids.

Before discussing more about acid corrosion inhibitors, first let us

get an insight into what corrosion is all about and why acidic

corrosion occurs

• Most industries all over the world involve the usage of metals and their alloys in any form – be it for raw material purpose or for using them in the construction of their machine parts.

• Different kinds of metals, till date, remain an indispensible part of any industry irrespective of their nature of operation.

• These metals or metal structures require proper maintenance or else they undergo slow deterioration by the action of atmospheric gases, moisture or other chemicals.

• This chemical phenomenon of a metal undergoing destruction due to environmental factors is referred to as Corrosion.

CORROSION

CORROSION• Corrosion may be regarded as the

gradual abrasion or deterioration of a metal by electrochemical or chemical reactions with its environment.

• On account of corrosion, the useful characteristics of a metal such as malleability, ductility and electrical conductivity are gradually lost.

• Rusting of iron can be referred to as a common example of corrosion.

• The rate and extent of corrosion mainly depends on the nature of the metal as well as the nature of the environment.

ACIDIC TREATMENT

• To prevent metals from corroding, protective coatings of different types are added. The outermost surface of the base metal usually consists of impurities like scale, rust and grease.

• These substances, if present at the time of coating, will give porous and discontinuous coatings.

• In order to get a uniform, smooth and coherent protective coating, these substances are to be removed by certain methods which include the application of acidic treatment.

• This process of the removal of the oxide scales and corrosion products (rust) from the surface is called descaling. In this process, the base metal is dipped inside the acid solution at higher temperatures.

• The acid penetrates through cracks and pores of the scales and then their dissolution takes place.

• Acids like sulphuric acid, hydrochloric acid and nitric acid are used under dilute conditions.

NEED FOR ACID CORROSION INHIBITOR

ACID CORROSION INHIBITOR

• Prolonged exposure of these metals into the acidic solution may cause gradual wearing of the metal surfaces. In order to prevent this type of corrosion, inhibitors are added.

• Acid Corrosion Inhibitor generally helps to impede corrosion by adhering to the metal surfaces and forms protective films which serves to prevent both cathodic and anodic reactions.

• Acid Corrosion Inhibitor is designed specifically to inhibit the acidic attack on various metals such as Brass, Copper, Tin, Nickel, Zinc, Lead, Galvanized surface and all other type of steel.

• It can be used for blending or formulating pre-inhibited descalant or acidic cleaners.

RODINE ACID INHIBITORS• Rodine range of acid inhibitor products serve as

the worldwide standard for acid inhibitors.

• Rodine inhibitors have been formulated to provide effective protection to base metals from acidic corrosion

• Helps in reducing iron build-up

• Helps in improved protection of equipments

• Accounts for better finish and appearance

RODINE ACID INHIBITORS

• Aids in eliminating chances of over pickling

• Rodine range of products include inhibitors that are designed for use in most acid cleaning operations without affecting the productivity

• Finds application in the following industries: Iron & Steel, Power Station, Petrochemical &

Refineries, Heavy Engineering Industries, Cement, Glass & Ceramic Industries, Sugar Processing Industry, Miscelleneous Manufacturing Industry, etc.
